RE: slow stick questions
Coupla things,
If your plane pulls to one side or requires a ton of rudder trim, check that the wing is not warped (one tip droops more than the other). It can be straightened with a hairdryer. Use masking tape to get it the right shape, heat it up and let it cool completely.
Other thing, you will lose control authority with the motor completely off at landings. Keep some air moving over the tail to retain control.
Finally, replace the rear wheel with a skid (just remove the wheel and bend the wire) and your landings will be SHORT. I fly in front of my house now in the cul-de-sac.
Regards.
