Gaba,
Make sure you tail bearings are glued into the carbon plates. I got vibes when the bearing came loose and started spinning in the plate. JB weld does the trick.
Tony,
The tail grips, pitch sider and shaft are 5g lighter than the stock. Not sure on the grips alone, but i like the look of the metal grips. The plastic stock ones just bring the look of the heli down.
I might get their break always too. I hope theirs work as well as stock . Even if stock ones are a pain to replace, I have had two extreme crashes and canopy has seen no damage
I am keeping that all stock. I changed the tail belt tightness by elongating the tail boom slots and got that to b just right... It was flying beautifully... Except my esc bogging out and the dumb thumb lol
Fly safe!!have fun!
