So much to like about the Demibot and with the collaboration between Bot and Tommy it's the clear winner for me. The extra room and mounting in the back is more HDZero freestyle friendly. Great video Joshua 🤟
Thanks for the honest review, Joshua. :) Just incase anyone is looking at the TanQ - I want to be upfront - it will not accept 20x20 stack - only 30x30. The frame that Joshua has in this video is a new version, that has already been strengthened around the break point from the Rotor Riot - straight into the ground video. I literally called the manufacturer the next day and revised the design. Always improving. Please tag me, anyone who has broken the TanQ and I will continue to make it the most durable frame on the planet. :)
I think Bot and I totally have similar needs and I think he did a great job with his frame. Congratulations, Botgrinder on making a super durable frame. Love it. :)
@LetsFlyRC I broke one in two different places in two different flights. I wrote RotorRiot about it just yesterday. Happy to provide details but prefer not to put them here.
@@matthewpequignot1026 please message me on Facebook if you have it, or email shawn@rotorriot.com. I would love to know where it broke so I can make sure we fix the issue, if it already hasn’t been fixed. So far, I have updated the bottom plate, the arms, and more changes are coming in the next batch. Everything is backwards compatible. My goal is to keep making the TanQ better with each iteration.
Hi, Mechanical engineer here, having more threads through a nut gives some redundancy if it backs out at all, but the entire load is carried by the first 3 threads, so as long as you have 3 threads through, it’s as strong as it will be
Older machinist here. Always depend on application. 12.3 button head. I ran machines long ago we used metric and standard Allen wrenches with six foot pipe to tighten the strongest black thick bolts, most expensive.get what you pay for.
Absolutely, and I'll just add to that that that's 3 full threads (tips of screws don't count) and into a steel nut. Into Al or plastic I go 1.5-2x the diameter of the bolt respectively as a rule of thumb, but in a lot of cases you might not even need all that clamping force. It also assumes you want the bolt to fail, it's a lot easier to replace a bolt than a threaded part.
@@Hobz79 You are both correct. I suppose I was saying that as more of a fun fact. It was certainly not design advice. I would always recommend at least having the screw all the way through the nut. Preloading plastic like that isn’t usually to the advantage and will more likely cause failure of the plastic fixture. Bolts are the most easy thing to replace
I’ve been flying the demibot all summer and have been LOVING it. I’m much more likely to try difficult tricks because of how unlikely I’ll break something. It’s definitely giving me a lot more confidence that I wasn’t getting from my old Nazgul5X. Despite being significantly heavier, I’ve tuned it to fly pretty damn well in comparison. Props to Ummagawd and Botgrinder for this frame 🙌
Flown the botgrinder frame for the last few months and ive broken 5 backplates, the design and placement of the holes + no standoffs means it breaks quite easy, never broken an arm but 5 bottom-back plates
A center standoff at around the base of the bottom-back plate would have done the trick, no prob with the bolt head if you use a battery pad. Leaving it unsupported like that even with 3mm CF is asking for trouble.
@@MallyFPV yup or even better good old 2 standoffs in the back right after the stack would of made it unbreakable..not its built like a lever increasing force on the backplate
I fly both frames, have only had to replace a few motors with my Demibot and the bottom plate on the Tanq! They both pass a durability test that’s for sure.
The Tanq is designed for the battery to be mounted in a toilet tank orientation. Hence the two holes for the battery leads/strap in the top plate, and the lack of indents on the side of the top plate for a strap.
Being a very old machinist, anything can be made,fast, cheap. Bot's the best. No bs with that boy. I am 66and say that with all due respect. Love his life story. The man among men
I have a Demibot, and it is my favorite quad. DJI 03, and Imperial motors. Survived many many crashes. Picked up a 3d print kit from Brain3D. Can't wait to get the 3.5".
Silly thing: I guess you actually only need 4 pieces for replacement. I think the arms are interchangeable! Edit: JB figured it out at 5:40 . Im dumb, ignore this comment!
I'm flying the volador right now. Im really enjoying it. I haven't gone bando bashing with it yet, though. I almost got the demebot instead. I love Bot!
All I do know imo bot did it wrong with the park. Went from donate and if he doesn’t get to 70 grand in a certain timeframe he will give it all back. Broke his promise on that.I knew it wasn’t going to go good from there.Then he said the park would be for everyone to go fly at. Now he buys a landlocked land that he will take 10 people he picks once a month for the summer only. Haha, so basically he bought land for himself that we get to go fly whenever it works for him. I see him say he’s doing with what money he had to work with. That’s exactly why you should have given everyone money back when you didn’t hit your goal like you said you would anyway. I don’t hold any hard feelings but I’ll go back to my never donate money to people because some people just can’t keep a promise on what they say.
I didn't like the whole hand select 10 people a month for a private trip thing at all either. When I heard that I was disappointed because now it feels like it will be hard to get permission to go to what was supposed to be a park for the people. Oh well reality sets in I guess. I still respect him for what he is doing and enjoy the content.
I went with the tanq for one main reason: Now obviously they're both intended to be indestructible but the Tanq protects the camera way better and the o3 camera is freaking expensive.
Love the Demibot frame. I was gifted one at Christmas this last year. my only complaint is the battery strap placement seems to be VERY far forward. I would prefer if it were about 10-15 mm back.
WOW, looks like Tanq is going to win! I'm going to buy that instead. And from my years of experiences flying several types of 5 inch frames, arms always broke.
And for the screw ripping off the hole of the bottom plate, the solution to that is to use a metal washer. A single m3 metal washer might be around 0.5-2g. That's light!
@@neilfpvsince the “three full throttles into the ground” video, the bottom plate has been reinforced in that area, and won’t break there anymore. The frame Bardwell has in this video is the updated version. The version in the RR video had less meat around the screw.
it's crazy how the Apex design has imposed itself as the oubvious best, and every strong frame nowadays is a variation of the apex. Love the looks of the demi-bot frame.
The battery strap for the tanq is pretty good spot if you know where it goes and it's called a toilet bowl style. It is impossible to slip or eject your battery
Needs longer screws for the arms on demibot. I put longer ones in mine after ripping out a few of the originals. Slightly longer screws are holding up way better
The Tanq does something that FPV Cycle does with their Fouride, although it's turned 90 degrees, that I think every frame should do. Slots in the top plate to weave the battery strap through the top plate to not only hold the strap in place, but it also keeps it from slipping around. I don't know why every frame doesn't do this.
12:50 umagod battery pad can very easily be cleaned using duct tape. Just stick it on and rip it off to lift all the dust and debris. Your pad will be back to full health
BOTH GREAT FRAMES.......BUT I JUST FINISH BUILDING THE DEMIBOT .......LITERALLY JUST DID A TEST FLIGHT......I LIKE THE WEIGHT BALANCE....WILL DO A 6S FLIGHT IN THE MORNING......THANKS JB
My preference goes for frames that use a cage to protect the camera. Also 8mm arm feel cool. I am very satisfied with my armattan rooster rooster except for the fact I stripped one of its holes (titanium cage hole lost the battle with stainless screw).
I have dropped my TANQs from well over 40 feet because of stupidity and both times, no frame issue but bent motor shaft having to replace the motor. Something had to give. Arm is cheaper. Maybe 6mm would have broke and left the motor fine. Love the TANQ with 2506. Fly on.
The demibot is a very well thought out frame, not surprising with Tommy at the helm. A great mix of durability, bad ass looks, and features! The Tanq ain't no slouch either but I'd go Demibot
I gotta say, I am not a fan of the lack of design of the tanq's top and bottom plates. As you stated it won't hold your battery straps in one place as reliably,but I also feel like the solid piece of carbon with no cuts it anything is kind of cheap/ugly looking. I know the battery mostly covers that area in flight, but I feel that having cutouts in the top and bottom plates aids in ventilation
I love my Demibot. Heavy? Yes. Breaks less than my bind n fly's. Definitely. I'm not a great pilot, I fuggin crash. A lot I'm always going a little harder than my skills. Usually around buildings and tall pnw trees. I appreciate the extra strength over a Roma or Nazgul. With some choice 3d prints it has saved me so much money and time in replacing arms and motors.
The demibot looks awesome. Just wish the props were a little less in view. That much prop is distracting. Want just enough to know what's going on if I crash. It's all about preference.
I broke a bot back mid plate and my first bottom plate had delaminated at the counter sunk screws. I like it but for the price I switched my 5"s over to RDQ Source one v 5's. when one brakes I will just grab another. Also my tpu mounted camera would end up looking more at one prop then the other after a crash. Had to e6000 it to prevent it from moving.
For weight you also have stack screws in the botgrinder frame when you weighed it, and not in the tanq. I would think those frame screws weigh more than the 3d printed bits, making the botgrinder frame more than 10 grams lightter.
The Demibot is totally the frame for me. It's beefy and has room for HDZero. The only problem is that it is sold out everywhere so I'm waiting for it to get back in stock.
The Tanq can not take a 20x20 stack unless you drill extra holes for that like i had to do. or get a 30x30 to 20x20 adaptor plate. people should know this if they are thinking about getting the tanq. but it is still one of the best frames for bashing!
@@LetsFlyRC Brother i want to thank you for finally building a quad with such thick arms. it is amazing! the only quad i have found that is as tough as this quad is the kinfpv At6 all aluminum quad. i have that also and it is a tank as well. but i don't think you can buy that frame any more so it's your's or nothing. if you build another frame in the future please include 20x20 mounting in the front and 30x30 mounting in the rear for us analog guys that like to run the AKK 2,000mw VTX. but i was able to modify your tanq to accommodate all that pretty easy so thanks a million!
i’m really loving your content and i’m thinking to sell my mavic pro to get an fpv drone, i was thinking about the geprc mark5, the o3 version, studying electronics at school, i come across lots of sensors, i saw in one of your videos of betaflight that it could be hooked up a sonar sensor, could you do a video about this topic?
Demibot Demibot Demibot. Best frame I have ever had. Flys great and you can bash it a lot. May get a crack here or there but it keeps on ticking!! Pick one up if you can they go fast!! And fpvcycle 25mm motors are like a kiss on the butthole mounted on the demibot😘😘
DemiBot wins, Design and look (Imaging "JB kiss omuaaah"), one thing to notice is props will be in camera view in demibot more than Tanq.... that's only thing and for me it's fine. @Joshua Baredwell ...... It's out of stock in every link you provide. lol
Nice to know, I went with the MK3 also and have been worried about it and even purched two extra arms :). so glad you posted so now I feel better, thank you
@@mathew-street yes! Its a TANK plus! Ive had it fall from over 100 ft and only wrecked a prop! Had hard hits and frame shrugs it off! Ive not replaced one arm so far in a year and I fly hard….. you will love it! The problem with the two frames in this vid especially is the weight…. The Skyliner is in between the flimsy and heavy such a perfect combo!
The Armattan designs are solid, but a little dated in my opinion. I would expect this to be more durable, although Armattan does have a lifetime warranty that might make up a difference.
Armattan Marmotte/ Badger for the Win! It's 40-60grams lighter, titanium camera cage to protect the front end and keep those expensive fpv cams alive. And most important, a lifentime warranty to just keep replacing the bits yoh do break. ImpulseRC Apex is another great frame for bashing concrete, and has a 2 year warranty. Anything you hit on concrete will eventually break, so a bit of balance will make yohr quad fly better and you'll be less likely to crash sooooo hard...and a lifetime warranty when you do explode the thing 🤣
Why aren't more frames made of aluminum? Carbon fiber is way more expensive, it breaks instead of bends and although it has a higher strength to weight ratio it's mostly strong in tension. it's only 30-50% as strong in compress which seems to be often over looked. I assume there is some other reason aluminum isn't more common?
@@deathlocus1571 I was thinking that too but Aluminum (AL) can be hardened to the point where it would fracture like Carbon Fiber (CF) but having it bend would seem to be an advantage. FC are good enough they could compensate for a bent arm to at least finish a race. Aluminum can be stamped or use aircraft grade 7075 ( still cheaper than CF) to make the parts much lighter. Or even a AL/CF composite to reduce the cost. AL also has the benefit of being a heatsink. IDK, I assume there's a smoking gun reason but it does make me want to cut a frame of of AL to try it :)
Quick google shows the specific strength (strength to weight) is >4x of Al. There is a lot more to it but for back of the napkin calcs that's fine. Also remember, that extra weight hurts you in an impact. Going the other way, I'd be interested in frames that are plastic (something like injection molded glass filled polycarbonate), but the tooling costs would be immense for a small market like freestyle drones. RC cars take a huge beating using just plastic parts. You can get more creative with the geometry, such as ribs, that could make up for some of the lack in stiffness.
@@Hobz79 The quick answer from google is generally correct but incomplete. CF being flexible threads bound by glue It's really strong in tensile stress but in compression the glue is doing all the work. Different binders and weave patterns can be used to increase the strength it's generally less than half the strength it has in tension. AL is a crystal lattice which is equally strong in every direction. Without a qualitative comparison it's hard to say. I thought for sure I would fine videos comparing the two but there isn't much. I found one but it's far from scientific. I agree my Traxxas is a beast but the injection molding is $$$. It's also more of a compliant device where it absorbs the impact, like you said might avoided with supports to increase the rigidity. I have a CNC, I'm thinking about cutting an arm out of several materials and testing it.
Agreed, however I got the pre-built TANQ, both versions pro and non-solder, and Rotor Riot uses subpar soft button head bolts. Easily sheared and stripped. Just spent a night replacing them on both, had to dremel a slot on 8 of them to get them out.
@@MountaineerFPVplease help me make the TanQ even better - I am always improving it - what is bad about the standoffs? The screws are a constant battle with out manufacture. We always request brand name screws and sometimes they screw that up. :/
So much to like about the Demibot and with the collaboration between Bot and Tommy it's the clear winner for me. The extra room and mounting in the back is more HDZero freestyle friendly. Great video Joshua 🤟
Makes sense too, since bot likes using hdz
That's exactly why I bought this frame because I upgraded to HDZ and wanted something that wouldn't shit the bed

i’m really loving your content and i’m thinking to sell my mavic pro to get an fpv drone, i was thinking about the geprc mark5, the o3 version, studying electronics at school, i come across lots of sensors, i saw in one of your videos of betaflight that it could be hooked up a sonar sensor, could you do a video about this topic?
U for got smooth style better then all
I think the tanq suppose to be toilet tank batt mounting? Possibly why it doesn't have that waistline?
I broke 7 arms in the demibot. But behind the small screws. And also the screws bent and it was almost impossible to get them out
I still fly my trusted Aliens.
Bortgander he’s the best!
Demibot Demibot Demibot. Best frame I have ever had. Flys great and you can bash it a lot. May get a crack here or there but it keeps on ticking!! Pick one up if you can they go fast!! And fpvcycle 25mm motors are like a kiss on the butthole mounted on the demibot😘😘
I really like the grl fpv pro2 for super strong frame… lifetime warranty on the arms too ;) interested to hear what you think?
DemiBot wins, Design and look (Imaging "JB kiss omuaaah"), one thing to notice is props will be in camera view in demibot more than Tanq.... that's only thing and for me it's fine.
@Joshua Baredwell ...... It's out of stock in every link you provide. lol
Need to make fifty of each and thrash them until last quad standing
soo, we gonna get a video of you flying the demibot?
Try the armattan roster 5
Also sends??? 5:14
I just got one recently but haven't built it up.
Team maniacs oily rig
Lost my demibot in the river... Fitting. @botgrinder hates water more than cats.
My Skyliner MK3 has been a tank itself! Ive had bad crashes and nothing has broke! La Drib did the damn thing!
Nice to know, I went with the MK3 also and have been worried about it and even purched two extra arms :). so glad you posted so now I feel better, thank you
@@mathew-street yes! Its a TANK plus! Ive had it fall from over 100 ft and only wrecked a prop! Had hard hits and frame shrugs it off! Ive not replaced one arm so far in a year and I fly hard….. you will love it! The problem with the two frames in this vid especially is the weight…. The Skyliner is in between the flimsy and heavy such a perfect combo!
@@LovesM855A1 I have two skylites and now the MKS is coming in so now I need to work on my rates and his tune is cool, just too slow in the spins.
Would you suggest one of these over an Armmatan for durability?
The Armattan designs are solid, but a little dated in my opinion. I would expect this to be more durable, although Armattan does have a lifetime warranty that might make up a difference.
@@JoshuaBardwell Thank you soo much for the reply and advise..you are the BESTEST my brother, the community appreciates all the work to put into it
Armattan Marmotte/ Badger for the Win! It's 40-60grams lighter, titanium camera cage to protect the front end and keep those expensive fpv cams alive. And most important, a lifentime warranty to just keep replacing the bits yoh do break. ImpulseRC Apex is another great frame for bashing concrete, and has a 2 year warranty. Anything you hit on concrete will eventually break, so a bit of balance will make yohr quad fly better and you'll be less likely to crash sooooo hard...and a lifetime warranty when you do explode the thing 🤣
I’ve got a DMR Thunder that seems tougher than both those frames…
Is there any tanky LOS frames?
Why aren't more frames made of aluminum? Carbon fiber is way more expensive, it breaks instead of bends and although it has a higher strength to weight ratio it's mostly strong in tension. it's only 30-50% as strong in compress which seems to be often over looked. I assume there is some other reason aluminum isn't more common?
Probably because aluminum bends and carbon fiber doesn’t. And metal is heavy.
@@deathlocus1571 I was thinking that too but Aluminum (AL) can be hardened to the point where it would fracture like Carbon Fiber (CF) but having it bend would seem to be an advantage. FC are good enough they could compensate for a bent arm to at least finish a race. Aluminum can be stamped or use aircraft grade 7075 ( still cheaper than CF) to make the parts much lighter. Or even a AL/CF composite to reduce the cost. AL also has the benefit of being a heatsink. IDK, I assume there's a smoking gun reason but it does make me want to cut a frame of of AL to try it :)
Quick google shows the specific strength (strength to weight) is >4x of Al. There is a lot more to it but for back of the napkin calcs that's fine. Also remember, that extra weight hurts you in an impact. Going the other way, I'd be interested in frames that are plastic (something like injection molded glass filled polycarbonate), but the tooling costs would be immense for a small market like freestyle drones. RC cars take a huge beating using just plastic parts. You can get more creative with the geometry, such as ribs, that could make up for some of the lack in stiffness.
@@Hobz79 The quick answer from google is generally correct but incomplete. CF being flexible threads bound by glue It's really strong in tensile stress but in compression the glue is doing all the work. Different binders and weave patterns can be used to increase the strength it's generally less than half the strength it has in tension. AL is a crystal lattice which is equally strong in every direction. Without a qualitative comparison it's hard to say. I thought for sure I would fine videos comparing the two but there isn't much. I found one but it's far from scientific. I agree my Traxxas is a beast but the injection molding is $$$. It's also more of a compliant device where it absorbs the impact, like you said might avoided with supports to increase the rigidity. I have a CNC, I'm thinking about cutting an arm out of several materials and testing it.
Haha when I'm farming and someone can't muscle something. I say use a fulcrum and they look at me like I have ten heads. Lol pivot point men.
Demibot ftw!!!
Im flying source one frame and thats unbreakable too 😅
Or you can buy 2 source one frames instead
Bot is FPV. Without his content, fov would be vary diff.
I have both, several frames of both. The Tanq is more heavy duty and takes a beating better
Agreed, however I got the pre-built TANQ, both versions pro and non-solder, and Rotor Riot uses subpar soft button head bolts. Easily sheared and stripped. Just spent a night replacing them on both, had to dremel a slot on 8 of them to get them out.
@@Monty_FPVyes! That tanq hardware does suck, especially those standoffs on the top.
@@MountaineerFPVplease help me make the TanQ even better - I am always improving it - what is bad about the standoffs?
The screws are a constant battle with out manufacture. We always request brand name screws and sometimes they screw that up. :/
DemiBot is the only one!!! Over a year! Multiple desert trips! So many crashes.. not ONE replacement! @Botgrinder
