GB Sukhoi needs servo advice?
Easysport,
Before investing in expensive servos for all control surfaces, I recommend going to a 6 volt battery to boost your 3004 bb servos in transit time and torque. I have the GB Sukhoi with Futaba 148's. I am satisfied with the response and effect. Good for learning without the cost. Then as you pocket book allows convert your rudder/elevator & ailerons in that order to high torque or digitals and you won't go wrong. Just my .02s.
