No.. didn't say the radio was what made you good. It is all in the shoes actually. I find that no shoes makes my ucd fly much straighter.
You are right.. if you have a plane that flies like crap (not ucd.. just any plane) you don't have to do use mixes or fix it mechanically or any other way. Really don't have to even trim a plane out. it can all be corrected in the sticks. How much you want to correct out by design, mechnical fix, mixing, or just getting a different plane is up to the pilot. Everyone is diff.
That is good that you can do all that really smooth with no mixes. Heck.. it is good that you can do all that period!! You need to get some of that on video. I have not seen a good video with rolling harriers on the ucd yet. I have seen harriers and inverted harriers. A good down on the deck rolling harrier I would love to see. And maybe some good waterfalls.. have not seen that yet either. They usually fall out before the 2nd waterfall.
http://www.3dbatix.com/ has some ucd stuff and tulsa3d.com has a cool ucd on floats. Still.. no good rolling harriers!!
I think I am almost have a good rolling harrier after mixing the ke problems out. Flew like a different plane. Just only got 1 flight and it was almost 3 weeks ago.. no time. I did it once, but, might have been fluke.
