Perfect! You will get it built fast! Goes together super quick!
Coming along beautifully! Above and beyond always my friend. Going to be an Incredible Heli once you get it in the Air. Enjoy the Build, Jeff!
Thank you! It’s a incredible heli so far! Like all SAB the quality is incredible! Thank you!
Thanks for this 😊. Great video. My 420 has arrived so I will be following along.
Awesome! Hope it was helpful!

You’re welcome, it’s very high quality!
@@westhobbiesrc8051 it's already settled, i'm getting one soon, i can't wait
@@oriontaylor4271 You will love it! It’s an incredible model!
Thank you for sharing your experience and knowledge.
Bought the 420 since september 22. Due to a lot of personal issues just started building today.
I really like and enjoy the video while simultaneously building it.
You’re welcome! Thank you for watching! My goal was to make build videos that people could use as step by step with the manual! I’m glad you enjoy them!
Looks very nice
It’s super nice!
420 be here Monday. Thanks Jeff.
Awesome! Enjoy! Incredible heli.
So good Jeff!! Thank you once again mate. You are a blessing to all those in the RC Heli game. My Raw hasn't arrived yet, but I am grateful for the build video, I will be following along with you, and looking forward to part 2 and your thoughts as always. Stay safe and Happy flying Jeff!
Thank you Rob! I appreciate it! I try my best! You should get yours next week! They are shipping Monday I believe! I hope all is well with you and your family! Stay safe!
@@westhobbiesrc8051 Shipping Monday? ...woot woot!!! as far as I know I was literally the 1st pre-order Helidirect had -- waited for the 0:00:00 count down LOL
@@javierarroyo7095 as far as I know yes the shipment will be going out to everybody on the 29th. So you should have yours very soon!
Really enjoy your videos, thank you for the excellent job! Very instructive for a newbie like me! I'm building my R420 together with you, following your steps. :) I received my kit yesterday from Rotorquest! Lucky me. They were really fast! :)
Thank you! I greatly appreciate it, I make my videos as informative as possible so that way everybody can follow along step-by-step and have all their questions answered! I’m glad you find these videos very informative! Part two will be out Monday so hopefully you can follow along with that as well! You got your kit very fast! Enjoy the build!
@@westhobbiesrc8051 Thank you, can't wait for Part 2! Will buy some popcorn :)
@@ytluisase I want some popcorn too! Lol I hope it helps you!
I bought Goblin Raw420.
Not yet arrived. That's why I'm learning in advance with this video.
I am glad that you explained it very carefully.
Awesome! I’m glad and hope the video is useful! Thank you for watching!
hi , your instruction is very good . Thanks for this super Video. Best Greats from Austria, Vienna
Hello! Thank you very much! I hope the videos are helpful!
@@westhobbiesrc8051 yes, i am shore
Hey west I can’t stress this enough I love your videos they help me so much and super simple to under stand are you going to make a part 2 soon
Thank you for watching! I’m glad you find the videos helpful and useful! Yes! Part 2 will be out tomorrow!
Yea baby !!! Let’s gooo
Super excited on this one!
The decals twisted up on mine too when I put the screws in. I should have made the holes bigger but no biggy. I just cut out a small section and it looks ok.
That’s what I did, I used a washer that was just a little bigger than a tear and cut it with an X-Acto knife. On the one that I just built I cut the hole out to the perfect size and they did not tear.
Fab video mate, excellent build, thank you, just doing mine now. Just a quick pointer to mention for anyone building, the tail tensioner needs a bit more tension put on it before tightening it. (25:40 mins in) Page 10 in the instructions.
Note the orientation of the spring holder, it needs to be held another 90 degrees or so anti-clockwise whilst you tighten the bolt down. Happy building and flying!
Thank you! I’m glad you enjoyed the video, yes you can run your tensioner tighter, I’ve built 28 of them now and I find there is no one set every one had been slightly different! Great tip!
28!?! 😂 and 2 simultaneously I see! You’ll be building them blind folded in your sleep, dreaming about them!
Don’t be test flying them blind folded though please 😂
Exceptional videos though mate, all of them, really enjoy them.
for some reason, I had difficult time putting the bolt through the aluminum spring support.
I'm not sure if the aluminum piece was not machined correctly, and the diameter was a bit too small.
also, relying on screw tightness to hold the spring support angle, thus spring tension, seems iffy to me.
great video! remember 1 drink every time you hear "lock tight" and 2 drinks when you hear "retaining compound" or puffs whatever you prefer! just kidding! man that thing looks awesome. and anyone who has ever built a SAB knows how intoxicating there high quality is. cant wait to see your flight vids
Lol! Gotta make sure everyone knows! Loctite and retaining compound! Thanks man! It’s a incredible heli so far like everything from SAB!
@@westhobbiesrc8051 its good advice you dont want anything to loosen up and fail
@@RC-Heli-Overdose420 no you don’t! And with people watching my build videos I don’t want them to ever say “you never told me to use loctite” lol
Im gonna do the same servos and fbl on mine. Itll be my first kit build heli. Only been flying a little over a year.
It’s a perfect first Build! Love mine! SAB makes the best kits and best manuals!
@@westhobbiesrc8051 I knew id get one when I first saw it. Its a good size and I love DD low parts count and simplicity. A step up from my 330s
Man - can't wait to get my preorder!! ....Jeff, why did you decide to use the plastic servo arms vs the aluminum ones?
So for two reasons, one they will break in a crash and save the servo gear set. Two, the metal horns are not tapped. So I could tap them but I know not everyone has a 2mm tap or the ability to do so.
Nice with the RED servos !
It matches nicely!
@@westhobbiesrc8051 Why in the 3rd hole the ball in the torq's ? it's more of 15mm ( manual recommend 13-15mm) . 19:27min of the video .. Why not the 2nd hole in the servo arm
@@marcossallua1984 two reasons, number one is for more cyclic throw. Number two and most important is for a straight pushrod. Using the second hole the push rod has a slight angle and the straighter it is the better.
@@westhobbiesrc8051 Thank you for the quick response!
At the 35-second mark, you said you have the grommets for the tail servo. Are they included or do they need to be ordered separately? And if so...what is the product number and description?
They have to be purchased separately, the are “not needed” but they help lock the servo and stop it from ever moving even the slightest amount.
www.helidirect.com/products/torq-replacement-servo-washers-for-torq-kst-mini-servos
Are you able to provide a link for the Torq grommets for the tale servo? I see so many options and have no clue! Thank you.
Hello!
What is the name of the plate that you used to check the servo arm for 90 degree? Where can I get it?
Thanks for the video. it is great I learn a lot from you..
Thank you, I’m glad you are learning. That’s a servo gauge. It comes with the kit.
Can you recommend a CA Glue that works pretty good for tail push rod or any parts of the 420 Raw that requires CA? Thanks
Thanks for a great video. Doing my first heli build with a 420 Raw I bought when it first came out. Head and tail built, but the swash (ball joint) is a bit "sticky" when I move the head around and it bottoms out. Smooth all around otherwise. I have followed the manual and your videos as I'm building, so not sure if this is normal. Not sure the servos will even travel that far in normal operation, but want to correct it before I proceed. Any thoughts?
Thank you for watching. I’m glad these videos are helpful! The RAW 420 is a beast! Yes, that’s normal, the links will wear in and smooth out in a few flights. You will never get those travels to bind the swash after setup. I would not worry about it.
@@westhobbiesrc8051 Thanks! I did notice after rewatching 15 times that the direction of the bearing race matters...gotta check that tonight! Videos are really helpful, I appreciate you doing them I can imagine they are time consuming to produce!
Have u tried the Torq BLS 0808 servos maybe even on your RS4 vs the 508 u have, if so any difference ?
yes I have on a Goblin 380 three blade, I didn’t really notice any difference other than they felt a little stronger.
Is there a difference between the Lds grease and microlube? The manual lists both being used. Are both required?
Yes there is a difference between the two. LDS is only used with gear box’s (transmission) or OWB. Everything else is Microlube. I highly recommend it but you can use witch ever grease you like.
Jeff, you rock. I just buried my 420 sport like a fencepost...after 5 years and 500+ flights. Since it's discontinued, I'm going to get the RAW. I used and ESC 100 Amp from Hobbywing in the 420 Sport. Do you think I can re-use that in the RAW? I know they call for the 80 Amp max. Cheers man!
Thank you! I’m glad the videos are helpful! Yes, you can definitely use the Hobbywing 100. The last RAW I built had a Hobbywing 120! I run a 80a ESC in mine but pull well over 100 amps every flight.
@@westhobbiesrc8051 Thanks!
Sweet------ they started shipping pre ordered already?
No not yet, mine is won at IRCHA so I get it before anyone as I don’t have to wait for manufacture release is part of contest winning rules.
@@westhobbiesrc8051 thats awesome that vendors donate to these events like this.
@@biscaolena it really is! They donate a lot to these events and make them well worth it! Always a chance to win something big!
Can we see size comparison to the blade 360?
Yes for sure, it is bigger
Jeff - With my servos centered, the splines do not allow exact alignment with the alignment tool. All 3 cyclic servos are off a little. Can I adjust that with the servo driver?
Yes, so you center your servo then out your arm as close to center as possible then use the Tbox to fine tune the servo to get it perfect or FBL setup to get the servos perfect.
@westhobbiesrc8051 Thanks, Jeff. I'm using KST servos and a 6250hx flb so I wondered if I should wait until I start the flb setup. I don't know if my spektrum battery/servo checker will allow fine tuning. Research time...
I'm still a newbie learning how to fly with my M2 V2 , still on basic flying. Not that good yet when helis facing me still trying to avoid it too long. Could i fly that RAW 420 in Normal Mode like the M2 V2 Micro? Thank you
Yes you could definitely fly the 420, running a iKon 2 FBL you can set Auto Level like the M2 as well as rescue. Definitely practice your four-point hover it will make you a better pilot!
@@westhobbiesrc8051 Thank you so much. Thank you for your time.
@@submarineone You’re welcome! If you have any other questions I’ll be glad to answer and help!
Is a direct drive motor the way to go
I personally think so! Less parts count, very little noise and very efficient!
Hey Jeff: Have you built a 420 with a Spektrum 6250hx?
Hello! No I have not. I’ve built a lot of 420s but all with iKons or Vbars.
Sweet. That look really nice. Please share me all the order number of all the electronics. Thank you
WestHobbiesRC
That green retainer compound, can I use locktite green for that ?
I’m not sure if loctite green is the same as retaining compound I would have to look that up. But the recommended SAB is a great price and a great product!
@@westhobbiesrc8051 thanks, just ordered some :)
@@tbonesixtynine perfect!
I. Like. This. Helen copter😂❤😅😢
Thank you! It’s a very nice heli!
What frequency do you run your servos on
These are on 1520, you can set 760 if your have the programming box but it’s not needed on these small servos.
Does those sevoes fit on the fusion 360?
Yes they do, they fit very well and a great upgrade over the 3055
Still waiting for my 420 to show up on my door..
Soon! I believe Monday
Can a newbie even fly one of these?
Where to get the Torq servo setting device?
Here you go www.helidirect.com/products/torq-servos-programming-card
It rocks -- I got on as well - already recentered all my existing heli torq servos :-)
What drivers are u using
So my favorite driver to use is MIP but I use all kinds.
@@westhobbiesrc8051 Thanks for replying. I really like vid very informative easy to follow
@@westhobbiesrc8051 Thx brother keep up the great videos
@@michaelmoore4378 thank you! I appreciate it! Thanks for watching!
Ok I got my raw 420 built but the battery tray snaps in locks but if I give it a light tug it comes out. Is that normal?
No! That’s normal at all. The pack will fall out in flight. Check and make sure the pin is going all the way in the tray.
@@westhobbiesrc8051 Ok I fixed it. Can u make a vid of the upgraded xt60 mount on the 420 please. I followed the manual but the battery plate kept hitting it.
Holly crap that grease is expensive.
Yeah it’s definitely not cheap! But it is the best grease around. A tube of it last a long time. It was much cheaper about 6-7months ago it was almost half the price it is now. For some reason it has doubled.
I want one 😭😭😭😭😭😭😭😭😭
It’s a incredible heli! I hope you can get one!
Honors to EVERYONE helping me with the Setup… r42 (twin Brother of guess what…)
Fbl……. Fc6250hc
Transmitter nx8
ESC Avian 100A (brave to not have put on a 120+A esc)
And some servos that f-- me profoundly…
I Need some Guide to prevent this orange one from being *permanently* grounded….
Im about to Strike out swinging… giving my best for a Display Model…
If anyone can give me advice or somehow help me im happy…. My servos do what they want…. They bind up at ~5-6^ positive pitch and i did set it up mechanically as the Manual Said…. Damm it i am about to abandon this huge thing to serve as a Display Model…
Can you give what servos? Have you selected the proper HZ and frequency of the servo in the FBL unit?
@@westhobbiesrc8051 I got 333hz servos and I just didn’t give up
I will put in a vid in my channel to show u what I got
@@700sizehelisaretoosmall 333hz but 1520 or 760?
@@westhobbiesrc8051 I check it out
@@westhobbiesrc8051 i go check the specs of them
DON'T put locktite on screws that goes into plastic... Never. Only into metal/alu parts. Which you 'forgot' to put on the screws into the lock.
Use clear nail polish in plastic.
The Locktite will not hold up into plastic.
Lol no I didn’t forget any loctite. No you never put Loctite on plastic, you can use CA which works way better than the nail polish
@@westhobbiesrc8051 LoL, but you did put locktite on screws in plastic...
For example the landing gear.
Ohh, you missed locktite on the first grub screw in the main shaft.
And the nail ppolish is possible to take apart again, the CA is almost impossible.
@@x3mperformace no lol I never put loctite on anything plastic. The skid mounts are metal. CA comes off no problem.
