  • $35.99

Here at Tiny Whoop we have found the Crazybee F3 flight controller is the best board for the gram conscious pilot, this FC is 1.12 grams lighter than the Crazybee f4 Pro Fc and still has the built-in receiver for both DSMX/DSMX2-compatible and Frsky-compatible for your racing and acro needs. 

With less weight, you can easily justify using TW 333mah HV Batteries
