This Engine was running nery nice for about 80 flights, yesterday without any worning the Engine suddenly cuts in a Tic-Toc, hard land... - found out that the Hi needle was released all x threads untill a complete disconnection with the attached regulator.

I never touched it, this came pre-assembeled with the new engine. Wonder if this is common, should I periodically check it ?, should I use a small amout of locktight on the threads ?

Thanks

When I got mine it was loose,, had to tighten it maybe I should have posted my findings and I got the engine when it first came out quite a while back. Guess it's just me but I don't trust anything, meaning I'll go over any and everything to make sure it's all OK

Thanks Blade3D

Was lucky to have minimal damage, tighten the needle and back in the air, I assume that it was not secured tight enough out of OS production, but will preiodically check it in the future.
