Just built mine

10s 450 KV scorpion (5020-450) mod1 1 main gear 11 tooth pinion using 2x zippy 5s 5000 lips at 85% on the esc, 690 standard edge blades

Flys ok but a bit sluggish. It balances on the head but it seems tail heavy and the back end wants to drop a bit on spool down.

Guess really i need weight further forward, and maybe more head speed?

Help appreciated.
