I'm just a little confused about this: I have acquired 3 trainers:

Hobbico Superstar RTF, OS 40LA, 10 X6 prop, 60" wing, 5.5 lbs.

Older kit-built Great Planes PT-40, Magnum .46 GPS, 10 X 6 prop, 60" wing, 5.5 lbs.

Older kit-built Thunder Tiger Skykark, Magnum .40 GPS, 11 X6 prop, 65" wing, 6.0 lbs.

My question is the heaviest plane is the TT Skylark, with the bigger prop, but .40 engine. The PT-40 has a .46, but the smaller 10" prop. The TT Skylark actually has the lighter wing-loading as calculated by the bigger wing, but swings a bigger prop. I have all the engines tuned and dialed in and running perfectly with 10% nitro fuel.

What are the flying differences expected with the different combinations? Wouldn't it make sense to put the .46 on the heavier trainer with the bigger prop? I've only had one lesson in the air with and instructor with the Superstar, but to me, it flew too fast, admittedly there was a 12 mph wind, but it kept getting too far away too fast. I want to fly close in and land slow while I train.
