The only bane of a dead calm day to an RC'er is if you're headed out the door to go slope soaring or sailing at the pond.
I understand the purpose of the trike gear on a trainer. What I disagree with is the notion that tail draggers or inherrently difficult to fly. I've talked to some widely experienced fliers who are afraid to try a tail dragger because of comments by other fliers.
Yeah the Cub is tougher to ground handle than a Stick. But it still is a kick to fly and only slightly more difficult than anyother dragger. One up side is the increased understanding of rudder function. The other upside to the rear wheel airplane, is that the faster they taxi on take off the more direction stability they have. Unlike a nose wheel which will begin to track back and forth at a point. The result is more airspeed on take off rather than forcing the plane into the air to avoid the Laugh-In tricycle moment.
