Oh, you must be referring to these Danny 😁 I will be installing another set of these as well. For the record, anytime I do this, especially if I fly down our (concrete runway inverted pushing the blades, I always rebuild the heli main shaft and all. I only do it when there is a crowd ( plankers and younger kids) at the field and they get a kick out of it, Show them what a synergy can do.. Only problem, I bombed my #1 N7 doing the same trick and didn't have good results, price you pay showing off. 😎
