nice mine are coming in the mail today so im going to be ready as long as my friend has that screw... i cant find one locally anywhere... i did find some on ebay i bought but their not going to be here by this weekend

ziper_it · 02-10-2011, 03:10 PM

But is this 20mm screw for the main gear?

michael88997 · 02-10-2011, 03:27 PM

ya its the screw that holds the main gear on the shaft

eightythree · 02-10-2011, 04:07 PM

not sure if it's the same length but possible to use Rave450 'shank' screws..

I think I have some spares from the Rave I had last year, I'll check compatibility

ziper_it · 02-10-2011, 04:11 PM

So M2 x 12 would fit. I'm using the ones coming with the main shaft of my TRex.

michael88997 · 02-10-2011, 04:56 PM

thats long enough? the one i pulled was 20mm long

JustPlaneChris · 02-10-2011, 09:27 PM

The screw is called out as an M2x14 (pn MSH40031). I don't think a 12mm will be long enough to fully engage the nylon insert in the locknut, and a 20mm will be too long (but wouldn't hurt anything I guess).

michael88997 · 02-10-2011, 09:32 PM

Hmm I guess they measure the threads cause mine is 20mm from tip to tip, I ordered some 20mm so they will be here sometime this week, my friend is going to let me borrow a Jesus bolt from his extra 450 so I can at least enjoy the nice weather this weekend

Everything is repaired and ready to go, once u build this heli once the repairs take half the time...

Yep, M2x14 checked in the manual.

I've lost the nylon nut, so I'm using a metal one with loctite. I've already broken 3 of these screws, just the screws, and doesn't make sense for me to buy a main gear at time.

eightythree · 02-11-2011, 08:58 AM

Trex/Rave is 12mm, stock is 14. I checked before I installed the maingear last night and it should work.

Flip the Nylock nut around so you thread into the nylon first, or just use a regular nut like ziper it.
I used a little CA glue to hold the nut in place..
After install you can put a dab of locktite behind the nut for extra security, should be good to go!

michael88997 · 02-11-2011, 09:18 AM

Ya I'll make it work for this weekend, I just ordered some m2x14 off eBay so I'll have those to replace next week... Just did a run up after Resetting the beast and everything runs great

michael88997 · 02-14-2011, 09:04 PM

Is anybody using a esc that has timing settings of low med high? I have mine currently set on med and I flying a 16t on 100% tc and it doesn't seem like I have the power some have in their videos, I was going to try high cause my esc motor don't get hot at all but don't know how much my flight time will be affected

michael88997 · 02-18-2011, 08:53 AM

Does anybody elses tail fin vib just a little? I can see mine In the air vibrating, it doesn't seem to affect the heli and I just held it in my hand and felt no vibrations,

JustPlaneChris · 02-18-2011, 08:59 AM

Mine is butter smooth, no vibrations.

michael88997 · 02-18-2011, 09:25 AM

So your tail fin stays perfectly straight?

JustPlaneChris · 02-18-2011, 12:17 PM

Yep, absolutely motionless.

michael88997 · 02-18-2011, 01:06 PM

Hmm weird, I didn't feel any vibrations and my heli flys great, beastx doesn't feel anything, guess I need to check the motor mount

eightythree · 02-18-2011, 03:02 PM

The carbon fins are pretty thin... maybe loosen and retighten?

michael88997 · 02-18-2011, 03:25 PM

Ya it looks to me just the bottom half, from the top of the smaller hole or so is vibrating, since the beast doesn't act like there is a vib it makes me think it's just the fin, I could glue a popcycle stick on it to keep it from vibrating I just don't want there to be a actual vibration that causes an issue

woodworkjkt · 02-18-2011, 03:53 PM

Chris, on yours, which doesn't have this problem, is that yellow tail actually made out of a yellow plastic, or did you laminate yellow monokote to the flat sides of the tail before screwing it on? Wondering if a monokote treatment might also have a positive impact on the part stiffness... sort of like foam core posterboard gets added rigidity from having two thin paper skins on either side laminated to the foam.
