I don't know where parker is in relation to Colorado springs, but I can tell you that, when it comes to flying 3d, or anything for that matter, Colorado springs SUCKS!!! If Parker is anywhere east of the Rockies, count on flying at a minimum altitude of 5000 feet, which equates to a minimum 20-25% loss of engine thrust and overall loss of flight performance. If it's west of the Rockies, you may get down to 4000. I am new to Colorado Springs (moved from so-cal as well) and haven't had a chance to get much flying in, but people say that real 3D is practically impossible unless you have an EXTREMELY light airplane with lots o' wing area. Unfortunately that's like asking for perpetual motion, because you usually need a larger, heavier engine to recover the rediculous power loss. I have an Extreme flight Yak which is a very light airframe, and I stuck with the DA 50. People at sea level are getting 71-7200RPM out of a brand new engine with a 22X8, while we, at 6800 feet, are lucky to get 68-6900, and I have effectively lost about 3 pounds of thrust because of it. I haven't had a chance to fly this plane yet, but I am not thrilled about having to deal with these losses.
To give you an idea of how bad it is, IMO, I am moving back to California and better model flying was one of only a few key factors in my decision.
