RE: Balsa USA enforcer
Hi Rototrack,
The Enforcer is a kitty-cat. I started with the recommended throws and increased them after a few flights.
I had a lot of problems with taking off. I used retracts and the nose gear needed to be bent backward (caster) before I wasn't flipping it over on the runway.
I have the Tower .75 with the 11x7 apc. Great combo.
Have fun & good luck.
Bill
PS Don't forget that there is no rudder when landing. I forgot an did quite a bit of damage the first time. After the rebuild I mixed rudder into the aileron channel - just in case.
