that dam bolt again!!! lol

[squeaky pete]

that dam bolt broke again!!!!! the one that holds the main gear on the main shaft!!!!! got away with my blades again!!!! wahoo!!!!! a slight chip!!!! done the skids, tail blades and torque tube gears on the front, not bad eh?? lol

so the question is, do you need to keep changing that stupid bolt??? or am i just abit aggressive and she cant handle me??? lol wishful thinking but thats twice now!!

its on my 600pro btw lol

Jesus Bolt? Someone on here had a bunch and they were good for 450 size

[squeaky pete]

its my 600, edited the above! soz!

If you're breaking Jesus bolts, maybe you over tightening it ?, or maybe you're using a fully threaded BOLT rather than the shouldered one that should be used ?

I've never broken a 600 Jesus (either top or bottom), even in a crash.

Edited to correct the mistake caused by my fat fingers on the keyboard !

sounds like you are doing them up too tight

[squeaky pete]

really? i didnt know you could over tighten them? how would that snap it? just out of curiousity

[jamiem]

ive never heard of anyone just breaking one in flight, either youve replaced it with a poor quality/wrong bolt or something else is amiss here. perhaps youve damaged it in a previous crash?

[squeaky pete]

wasnt one flight, i cant moan to much, in 39hours crashed 3times, 2 of which was that stupid bolt lol,thats the 2nd one that ive broke, just wondered if anyone else ha had this problem? or can i put a ultra high strength bolt in it????

[sacko]

Yup you can put a higher grade bolt in it, but the standard should be fine, you are prob doing it up too tight.. What bolt had you put in it?

[Janek]

or maybe you're using a fully threaded BOLT rather than the shouldered one that should be used ?

You never answered this question (although I did initially have a typo in it), it's VERY relevant to the discussion at hand.

You’re not using Stainless Steel bolts are you if you are that could be your problem as Stainless Steel will snap under load.

If not I’d go with the poor quality/wrong bolt idea if you were over tighten it you’d have problems with you bottom gear as it would be deformed.

HT Hexa bolts snapped on me when I tighten it too much. Fortunately it was still on terra firma. It did take me by surprise - we don't use torque wrench but may be we need it since helis are getting sophisticated and we have a numbers of suppliers/ manufacturers - some good manufacturers but a few are questionable.

[squeaky pete]

sorry, yeah it was a stainless bolt!!!! was shoulderd tho, oh well, learn by my mistakes, it wasnt super tight in there, not tight enuff to deform nothing, tight enuff that it wasnt moving lol so stainless is a no no, lesson learnt! lol many thanks peeps!

[jiberjaber]

I am supprised people trust stainless steel bolts in their heli's at all. I certainly dont after discovering myself how weak they are.

[sacko]

Dont think people know tbh, I certainly didnt. Its just by chance that there isn't one in mine at the moment.
