Default RE: Nitro models pusher Bobcat?

Well, I decreased the AOA, and have had better results, but will go further to almost 0/0 AOA.... it still just wants to jump and bounce on landing, and it's hair raising to say the least!
I have gotten the engine tuning sorted out, and it's running MUCH better!
I had two flights on sunday, where I got some impressive looking speed out of it, and was finally able to evaluate trim and C/G withoutworryingabout the engine.
Crashpro had taken some video, and extracted a few clips with the fastest passes. He then posted them in another forum for Doppler readings, and got a best speed of 145 mph out of a shallow dive. Very impressive, but I'm a bit skeptical that it was exactly that fast. ifdefinitelyfelt and looked like it was over a hundred, but a buck forty five? might be pushing it.... However, I understand it is pretty accurate....
I'm going to try an un-sprung front gear leg, and smaller low bounce main wheels next, along with moving the C/G back to 10.25". This plane is proving to be challenging, but a bunch of fun!
