@@JohnHaggerty-no5dl thanks for watching John, yes as I said if it was easy it wouldn't be worth doing! Thanks for recognising the hard work, it was a crazy summer designing and making the car in 3 months. I have some great ideas for videos to come so keep an eye out for those 👌

@@wasa7 thanks, roll on next year's events 👌

Hi Derek, thanks for watching and the compliments, its much appreciated. I probably should have realised I wasn't going to get anywhere with the cone too and stopped before the crash! Easy to say with hindsight.... And yes 2025 is going to be the year 👍🤞

Hi Chris, thanks for watching and for the complementary comment! Yes I'll make sure its running properly before the next event.

Hey, the FC didnt seem to have any problem on my previous speed car. In any case its isolated from the 12s by the PDU unit I'm using (Matek). Have a look at my next video and see!

@@steveeng1826 I am looking forward to it. The hub motor design has serious potential for these applications.

hey and thanks for watching. Yes the brakes are a concern, especially since the brakes are 3d printed so will only survive up to a certain low temperature before deforming. The braking strategy for my cars is to use aerodynamic drag initially, then use electrical braking from the motors/ESCs and finally the mechanical brakes to bring it to a standstill. I dont think I can reply only on the ESC braking because they are drone esc's not designed to deliver strong braking forces.

@@steveeng1826 I don’t know about ESC braking. There are many out there doing runs. That have Hit 225 mph and using ESC braking.

Hey, thanks for watching and commenting. On my first car I kept the same PID settings as the 6" quadcopter that the FC came from actually and it seemed to work well! I think the FC has an easier time of it as the car has wheels on the ground to give more instant correction, not like something flying. I put the ESC's under the plate to protect them in the event of a tyre blowout, but it did make them impossible to access which was not ideal! That will be improved in future 👍

@@steveeng1826 What FC firmware version are you using? What flight mode (acro, or)? Did you lay the FC flat or vertical and change gyro orientation or? TIA I mostly fly LOS drones and have a triple rate switch for roll/pitch, 1200/1750/1950, maybe you could use something like this for your car, to be able to turn around, but mellow it out for the speed run. ua-cam.com/video/uHoFfpLSb2g/v-deo.html&t

Hi, thanks for taking the time to write a comment, its much appreciated. I agree about the holy grail being active aero based on load cell reading of wheel load, I have that in mind for the future but I need to get the car working as it is first! Regarding the canard location you get an output of total downforce and moment around a reference point, from that you can work out the downforce distribution. I needed to put the canards as far forwards as possible to give it additional "front downwards" moment! Throttle control wise the holy grail of that would be some kind of traction control, another thing I have in mind for a future addition! Parachutes would also reduce the load through the cars speed controller, assuming that is used for braking. My strategy is to use a combination of aerodynamic braking, then the speed controllers, then the mechanical brakes to bring it to a standstill. If I run into issues with that then maybe a parachute would be the way to go. The belt drive solid rear axle car is Afxentis's, it certainly works well for him, his is close to hitting 200mph with it. It certainly goes with the sensible philosophy of "start with the simple"! Thanks again and why not try and make a car yourself, sounds like you have plenty of good ideas 👍

@@tetraktys6540 awesome, glad you're finding it interesting. thanks for watching and commenting 👌

Thanks, that was the objective 😃

The panic was real! Badly filmed but it had to go into the video! Thanks for watching 🙂

Possibly! Are you making or thinking of making something similar?

Yes, I am making a 1/10 scale formula student car(3d printed) with aproximatly the same setup. Only using 2s and servo steering also. It only steers a bit to quick now sometimes and then spins mid corner so was curious what you had for settings

​@@erwinbliek1247that sounds cool! I'd be happy to share the settings I used by email or something, how can I contact you?

I don't know if you have a public email or Instagram or something where I can contact you privately? I would rather not put my email adres in the comments. Otherwise I can create an extra emailaccount and put it in here

@@erwinbliek1247 Yes please try @stephenwallis14 on instagram. I'm not a big user on there but it could allow you to get a message to me. Thanks

Thanks for watching! Comments like this will make me keep going with the videos 👍There's plenty more to come!

@ this is great news. It’s nice to have some really enjoyable yet detailed and “serious” approach. And it’s quality well produced videos too.

Yes it was tight! And yes it's gonna be a long wait! Especially since I don't think I'll be running the beast car anywhere other than Rossa events due to the space needed. Nice idea on Spain! Some setup like motorbike track days could work where they take your bike down for you while you fly down.

Hi Jonathan, thanks for watching! I can't remember where the carbon spring idea came from, but a single spring is what I had on my first car with the Beast car having a double spring arrangement a bit like a double wishbone car suspension. Keep watching and you will see what happened at Rossa RD3 soon!

Thanks for watching! Yes I also found it great to see it coming together, its a shame it was such a rush in the end but I managed to get some footage at least! Enjoy!

Thanks and thank you so much for watching!

@ I had the same idee whit drone motor on a rc car and make it reali fast but I dont had the money for it but yours looks epic, good luck

Just remember you need lots of down force to have enough traction. Front wings after are necessary.

Great work. Thanks for sharing. Some of these shapes look a lot like the bodies made that Raz used. With that said you needs lots of down force to put the power down and fight blow overs.

@@rcraceandbash5472 hey and thanks for the message! I think the splitters and spoilers must be helping, because you're achieving some high speeds with your cars without them becoming airborne! But the open wheels cars will certainly have a high drag coefficient, which means you then need more traction and power to drive it through the air especially as the speed gets higher (as per the science of speed video). It's potentially a bit of a vicious cycle type situation! It would be interesting to do some CFD testing on an open wheeler to see if the body setup could be improved.

@@Liberty.Francis thanks for watching, glad you found it interesting! I was aiming to get some balanced down force but it's hard to say whether I achieved it or not. Time will tell!

@@steveeng1826 it was only a few years ago 150 was considered the max for an open wheel, yet here we are with some guys into the 170s. I think that says more about the power systems than the aero right now 🤣🤣. It would certainly be interesting to see how the open wheel performed on the modelling software

@@rcraceandbash5472 hey, thanks for the message, I appreciate it so much 👍 it's interesting to hear you think I've found a gap in the R/c UA-cam content, I'm happy to carry on filling it! Part 2 will be out same time next week 👌

That for watching 👌 I'm ready and waiting if you have any questions! Im aware that my videos are on a trend of getting longer but I still feel like I'm still just scratching the surface of these (interesting to me) topics!

Thanks for watching it Graham, your support and encouragement is much appreciated👌 I've got plenty more vids to make I hope you like them 😀

@@rcraceandbash5472 thanks for watching it Graham and for the feedback, it's much appreciated👍 There's plenty more videos to come too 😀

@steveeng1826 i look forward to each and every one of them 👍

Hi, thanks for the interest. I can give you a promo code so its free from Cults. Let me know your email and I'll send it.

@@benhamer9125 thanks Ben! YES MATE!!

@@rcraceandbash5472 hey Graham thanks for watching it! I am aiming for round 3, I'm not sure what state it will be in but hopefully will be able to do some runs 🤞 I have a lot of work to do! I Hope whatever you are doing for round 3 is going well. Funnily enough yesterday I was soldering connectors onto my lipos with 10 gauge wire using my Amazon soldering iron as per your recommendation 😀 it took max power but it did it nicely 👌

I can appreciate you must have a lot of work ahead of you. I only have two relatively simple cars and i worry if i will be ready! Glad the soldering iron worked out well for you. I had some goodies arrive from Mike at Onyx recently - he really is a great guy, so i spent the evening yesterday soldering 8mm bullets. Im hoping to get my 150 cap at round 3 and then go for the 175 next year. No doubt you will be hitting similar (or bigger!) numbers 🙂

@@alans4281 thanks for watching, it's gonna be a journey!

@@peterfelecan3639 hi and thanks for watching, yes I've been excited to show the iterative cycle, in future videos I plan to show how it went because it's moved on a long way from what I showed here. Thanks for the comment on the music, I think some of what I've used worked but not others, I'll be more picky with where and what I use in future! Using Simscale for CFD by the way which is free for your first 10 runs (with numerical results).

Round it more when looking from the side right? I have been meaning to check the pitch sensitivity of my more recent designs but haven't got round to it yet. Maybe this week! Thanks for watching 👍

@@steveeng1826 Yes, it should be sensitive to bumps in the road. Rounding the nose more when looking from the side should fix that. You have got a nose like 🏎️ and you probably one want one like 🚗.

​@@steveeng1826 add vacuum to the undercarriage. I don't know why full scale Land Speed Record chasers won't do it.

@@secretbassrigs this did cross my mind but I decided not to because I didn't want the extra weight and complexity. Plus if I can get the aerodynamics to work it would give downforce for free! Try it and let me know how it goes 😀

@@steveeng1826 there's an obscure AI maze race called MICROMOUSE that basically uses electric cars as Mice. it seems to improve traction and torque as much as it prevents "blowouts". good luck!

@@Drawliphant thanks for watching, yes I'll be using off the shelf wheels for this car rather than 3d prints that should be capable of 200mph. I haven't got a way of simulating lateral stability so I'm going to have 2 sizes of fins and the option to have up to 3 of them! They are definitely necessary, I ran my old car without them once and it went all over the place then crashed.. I think I have a solution for getting balanced downforce front and rear but will have to see how it performs in real life! Cheers for the tip on the hub motors 👍 Steve

Hey, thanks for watching it! Actually it does have an innovative leaf spring type suspension system of my own design, I'm looking forward to showing that in a future video. The bearings are a concern, they were on my first car too although they proved slightly more durable than the spindly 3mm motor shafts! The loading direction is better on the car than in a drone (radial rather than axial) and they have a 175kg radial load capacity, so I'm hopeful they will be fine! We shall see!

Yes good idea, I'll do this in a future video. Its fairly simple, just changing the mapping from memory.

Hey, I'm using Inav, I didnt change the PID's at all actually! Just changed the mapping.

Hi Botgrinder great to hear from you and thanks for watching it! I'm a follower of yours! keep up the good work ❤

@@Liberty.Francis thanks 👍 I'm using CFD and plan to make a vid on that soon 👌

@@steveeng1826 awesome looking forward to seeing it

Hi Graham, thanks for watching it. I'm looking forward to catching up with you and OB in September!
