engine? 4 a Cloud Dancer kit
I just flew my CD40 ARF for the first time last weekend. It has an OS .46 FX and very spritely performance. A .40 LA is quite a step down in performance, but would probably let you fly around "in a nice relaxing sort of way". The nice thing about the CD40 is that it is light and has more wing area than most sport 40 planes so you could get away with a LA40. I'd recommend a hotter .45 though. Love the way mine flies and I just throttle back to fly around in a nice relaxing sort of way.
I have just one aileron servo (Hitec 425 dual BB) and rolls are very fast and precise. I used the torque rod setup, with metal clevises on both ends of the pushrods so that the fit in the servo is very tight. I used a wheel output on the servo to get mechanical differential on the ailerons (more up than down).
What plan number and/or issue of RCM was the CD in?
Howzat,
