Thanks! I'd better not count the days needed to make the models, but it was worth it. They fly pretty realistic and I'm quite excited to see different flight behavior even from subtle modifications. Of course, Brushfire is noticeably different from Kwik-Fli. Both are very smooth flyers, though. Experimenting on model designs is my interest here.

My other interest is classic aerobatics, and for me 3D is boring (remembering a remark by Ben Lanterman). I don't even think the reflexes acquired by 3D flying are useful for normal flying. I rather take a moderately powered model and practise maneuvers involving stall - low power aerobatics. But that's just me.

Anyway, you just can't compare a classic pattern model (low thrust/weight ratio, high wing loading and speed) to a modern aerobat, more to a jet model. But the classic is more challenging because you have to compensate the propeller effects.
