ok thanks for the help !when i fly my super cub i hand launch it of course and then when it gets in the air and is flying left or right i adjust my trim to fly straight so when you say i might need an instructor to help adjust my trim is the adjustment similar or completely different? and is there alot of tuneing to be done on the nexstar engine its sounds like it shouldnt need much tuneing according to what all i read? and finally i guess i have to show how much of a newbie i am and go ahead and ask what do you mean by a "slow stick"?
