I Use a Acoms Hyabusa Technisport..2-Channel Controller


Its Awesome with Full Digital Controls.. and Weighs about as much as the 8 AA Batteries..
Since it is a JR Controller and my Sprint 2 uses a Futaba Setup I just had to reverse both the Channels and it works brilliantly.

Compared to the Stock Sprint 2 controller,the HPI TF-3, the Hyabusa allows up to 20% more power to the motor.. Strange but true I have gotten at least 5kph more since changing to the Hyabusa!
