Just a word of warning to those of you that reuse the bolts that go through the main gear to the shaft or the bolt (M2x12) that goes through the head and shaft.

I was flying, did a flip and the blades stopped. Dropped like a rock.
Nothing I could do.... Ended up being the bolt in the main gear broke.

I don't plan on reusing these type bolts once it already used...

That's why they call those kind of bolts "Jesus Bolts"...

I've always used the stock one on the T-Rex but always use a collared bolt on Xcells and Raptors.. no threads on the bolt until it comes out the other side of the head or main gear.

I prefer good quality steel socket hex head screws for that reason. I bought a few and don't reuse if the bolt appears stressed at all. The stock screws are just way too soft.

Align black hex bolts
Actually, Align did change from the soft silver Phillips head bolts to the black socket hex-headbolts ...Jlewis99, which one did you have? I changed mine out as I got spares..they are the 2mmx12 ones.

These were the silver phillips head screws.
Where can I get the stronger socket head screws?
I'm ready to order them as I also lost a brand new prolite pack in the crash.

Align black hex bolt
I bought a new head hub(black plasic one w/head button) and it was in there. The top is the same as the bottom one. Also believe it was in the First Aid Kit for the Xl too. The silver ones are of the same cheap grade as the ones they replaced in the tail. So the black hex bolts are the same quality as the replacement ones for the tail.

Your LHS should carry them. They're 2mm x 12 allen head bolts.

I have used M2x12mm Hex Head bolts from the first TRex. They don't break even in a crash! I got some at the LHS. They also come in Scott Gunnells Hex Head Screw Kits for the TRex.

Damn, that sucks. I will probably check my bolts more often now and always after a crash of coarse. Was your heli ever crashed before the bolt failure?

You real should replace it after every crash. You won't be able to see the stress crack.

The bolt probably is the same bolt from a previous crash.
I ordered replacement bolts for hexcrews.com.
(Socket head screws M2x12) should work much better.

Thats funny, I pulled my head off last night and noticed that my jesus bolt was sort of "Z" shaped! Glad I found it, I was wondering if they ever fail...

That's why they call those kind of bolts "Jesus Bolts"...
Because you go "Jeeezz" when it drops?
Because the bolt broke?
Because the heli dropped out of the sky? (Like a bolt of lightning?)
Because he couldn't do anything?
Did it walk on water?

I do not understand how this relates to it being called a Jesus bolt?

Cannot be depended on?
Breaks easily?
Needs inspection every 10 runs?
Keeps you flying?
He too was 12'?
Jesus sure didn't have a bolt thru his head and shaft...or main gear

Care to explain further ?

It's the first one.
Because you say "Jesus!" when it happens.
