They're not the big relaxing kites you think they would be!! my BUSA 1/4 scale se5a is one of my few "appropriately" powered planes, meaning it has zero vertical abilities. It's 20 lbs with a G38. It's flown on the wing; turns cost some altitude, and are best done with rudder and aileron together. Landings are actually easy, as long as the tail is kept up until airspeed bleeds off as the high angle of attack when the tail touches down will pop the plane back up in the air. A moderate breeze really shoves these planes around with all that wing & drag. The good news is that with those huge wheels & forward placement, they handle long grass & rough fields very well. OK, a DR-1 triplane may be a different story......
