SAB Goblin RAW 420 DD Build Part 1

[@足塚ドラきち]

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.

[@westhobbiesrc8051]

Awesome! I’m glad and hope the video is useful! Thank you for watching!

[@larrychamel]

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!

[@westhobbiesrc8051]

Thank you! It’s a incredible heli so far! Like all SAB the quality is incredible! Thank you!

[@richardbartlett6514]

Looks very nice

[@westhobbiesrc8051]

It’s super nice!

[@DetoursRC]

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.

[@westhobbiesrc8051]

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.

[@ultraporthos6884]

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?

[@westhobbiesrc8051]

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

[@scottbaddley72]

Have u tried the Torq BLS 0808 servos maybe even on your RS4 vs the 508 u have, if so any difference ?

[@westhobbiesrc8051]

yes I have on a Goblin 380 three blade, I didn’t really notice any difference other than they felt a little stronger.

[@ytluisase]

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! :)

[@westhobbiesrc8051]

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!

Hey Jeff: Have you built a 420 with a Spektrum 6250hx?

[@westhobbiesrc8051]

Hello! No I have not. I’ve built a lot of 420s but all with iKons or Vbars.

[@submarineone]

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

[@westhobbiesrc8051]

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!

[@submarineone]

@@westhobbiesrc8051 Thank you so much. Thank you for your time.

[@westhobbiesrc8051]

@@submarineone You’re welcome! If you have any other questions I’ll be glad to answer and help!

[@jjudd88]

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?

[@westhobbiesrc8051]

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.

[@jjudd88]

@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...

[@bentonn]

Thanks for this 😊. Great video. My 420 has arrived so I will be following along.

[@westhobbiesrc8051]

Awesome! Hope it was helpful!

[@javierarroyo7095]

Man - can't wait to get my preorder!! ....Jeff, why did you decide to use the plastic servo arms vs the aluminum ones?

[@westhobbiesrc8051]

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.

[@johnbess7320]

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?

[@westhobbiesrc8051]

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.

[@johnbess7320]

@@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.

[@scrc511]

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

[@dustinmaquet03]

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?

[@westhobbiesrc8051]

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.

[@dustinmaquet03]

@@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!

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!

[@westhobbiesrc8051]

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.

[@revers224]

Is there a difference between the Lds grease and microlube? The manual lists both being used. Are both required?

[@westhobbiesrc8051]

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.

Sweet. That look really nice. Please share me all the order number of all the electronics. Thank you WestHobbiesRC

[@jjtaylor78]

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!

[@westhobbiesrc8051]

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!

[@jjtaylor78]

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.

[@davidjacobs8558]

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.

[@colestaples2010]
