When I set-up for a takeoff, I always steer/angle the plane across the runway to avoid an inadvertent flight over the field staging area and I believe that is a factor to the right turn. Also, the field is a grass/bumpy field and my two trainers require a long run before gaining sufficient speed for takeoff. However, I will recheck wheel alignment which has been a problem. I just corrected a problem with the trike trainer to beef-up the front wheel assembly. The tail dragger trainer has a weak tail wheel assembly which presently requires straightening after each landing. This I have got to fix. The four star 60 has no such problems. My transmitter does not have expo capability for the rudder. I love those planes that seem to jump off the ground in 20 feet or so and go straight on take-off. The four star 60 does pretty well but I crashed it doing knife-edgeswith too much rudder and wrong use of elevator. However, I have it rebuilt now and its is almost ready to fly again. Yes, I will check the pattern aerobatics screens for information and training. Thanks
