To set the record straight, Stainless, mean's Stain-less, they are designed to not corrode, or rust, and they are not usually
stronger then steel. and for every hour you fly that heli, some poor mechanic spend's 3, trying to maintain it !!
If you did that to your rc/ model, i don't think it would have exploded.
Locktite is your friend ! Good luck with the next one !!
