so 3 times now, the starter coupler on the odin 90 has backed off, and this last time im sure it wouldnt have because i used red loctite, but it did back off ending the day of flying with it.

any tips or tricks out there from other odin owners to solve this?

I was warned about this when I built my Odin, but have never had it happen.

I cleaned the threads thoroughly, used blue locktite, then too a "star" lock washer, trimmed it to fit in the hole under the nut, and tightened everything firmly.

It has never backed out.

I used to do this with Hirobo Falcons in the 1980's, as they would back off, also. After I started doing this to the Falcon's, I never had the problem again, either.

yea, i thought of using one of those or even a thin lock washer, but didnt end up doing that. there is no hardware type store close, so i ended up cleaning everything really well, using red loctite on both the crank and starter adapter, let them sit for a little bit, then threaded it back on. this time when i did that, it was hard to get on, so it will be even harder to get off. once it was on, i wicked green loctite in, so hopefully it wont back out again. if it does, i will definately get the washer...

Well if it does hold it's never coming off again...lol.

Just a heads up about thread locking compounds...they work when exposed to air so next time put your loctite on then install components. If/when it loosens off the air that comes in contact with the loctite product makes it stiffen and prevent the components from moving further.

it should hold, if not, will go with the washer as i was thinking before i did this and as rak mentioned.

im well aware on the use of loctite and its the air that causes it to evaporate and concentrate the ingredients causing it to hold. i dont ever use red loctite on anything and using it has gone against everything i have said about using is. it can easily be removed if necessary by heating it up, but i dont want to, lol...

ive already hit it with the started numerous time and it has not backed off, but knowing my luck, it will happen at the field, haha...

considering i havent flown since i redid it all, was going to this week sometime, but the starter shaft on my align starter rounded out at the tip "POS", so i have to order a new one tomorrow, but i dont think im gonna order the align one. the tip on the align starter is apparently not hardened, so i need to check around before i get another ordered.

Never had any issues with it backing using red loctite. Make sure you torque it down real good.

well, i think im done with the odin... no sense in flying it if im out at the field and after 1 or 2 flights it back out. ive used red loctite, i even went and picked up star lock washer and trimmed it to fit and it still backout out.

so perhaps there will be an odin for sale shortly in the classifieds section, which sucks because its a great flying heli, but im refuse to keep dealing with this crap!!!

honestly its a pretty poor design in that aspect...

az,

I don't understand why yours is not holding, sir.

I wonder what is different between our two machines.

AZ is the bolt bottoming out perhaps preventing from tightening properly?

The only other thing i can think of is you have a wicked vibration in the clutch/starter housing but you would have noticed it....
