RE: Are Pattern Planes Good 2nd Planes?
Vintage pattern planes are fast flying planes as compared to current pattern planes. Rules today require maneuvers to be completed inside a box where as the vintage rules had no box - hot in hot out.
Control surfaces are much smaller than what are popular today. Result? Much less "authority" of the control surfaces. You better have your "A" game (or at least "B") when you are flying it. I had a Killer Chaos (60 size) and was doing a large loop. As I was finishing the final 1/4 of the loop a big gust of wind hit it head on. There was not enough elevator authority to pull it out before it thumped mother earth.
Guess I'm saying "no, not a good 2nd plane".
4Stars are easy flying low wing trainers. Pulse XT (60 or bigger) are very nice as well.
Now, if you were to build a kit ...
