I am building a tiger 60 and I need to decide on servos.
Tail dragger version, shorter wingspan with the dihedral taken out.
2 inches added to rudder
3/8 inch added to elevator
stock aileron length

I currently have 4 Futaba S3003 servos available from my trainer.

I need 5 servos for the tiger.

Do i need better servos for the elevator, rudder, ailerons or will the ones I have be fine?

Any suggestions for servo combination for this plan?
