A friend and I are learning to fly on a Hobbico Superstar MKII RTF. The plane flies quite nicely once it's in the air. Takeoffs are a little hairy. The plane rolls nice and straight down the runway but just below takeoff speed starts to go to the right and after takeoff continues to the right until full flying speed is reached. Once it's up and flying the trim is very good. It will fly hands off for several seconds.
Most of the time this is not a big deal but last week my friend was taking it off and didn't correct in time to keep it out of the chain link fence. Naturally we would like to avoid this in the future.
Since it rolls straight at slow speed and flies straight at high speed I figure the rudder and ailerons must be fighting each other somehow, buth I'm not sure how to go about correcting that.
Thanks for anything that will point us in the right direction.
