Which Class are You competing in?
I flew in 2 contests last year with my Sig Cap 231EX. I had carb problems with my ST2500. Stock carb. I had problems with my Hitec 605BB servos also.
I was embarrassed. With engine flameouts and poorly centering servos; I looked like an idiot who couldn't fly.
Engine replaced with ST3000 and OS7D. Servos replaced with Hitec 625MG.
I will fly this plane in Basic class this coming season.
I recently finished a H9 Cap 232 25%. I currently have an MDS 148 engine with Perry VP-20 pump. Hitec 625MG servos on ail. and elev. Hobbico CS-80 on rudder and standard JR517 on throttle.
Still working the bugs out of the H9 Cap. Only about 10 flights so far. Recently added the pump and having a "good" time tuning the engine to run with the pump. May install a by-pass loop in fuel system.
I look forward to the coming season. I love the competition. If things go well, I'll be competing with confidence this year. I'm a reasonably decent pilot. I will just have to consider last year a "learning year".
Good luck to all of you guys in the coming season.
