Rafeek,
Your input is much appreciated and will be taken into consideration.
I will be doing it this winter amongst my Topflite F4U Corsair build.
The cub with this set up is not a racer by any means, but it seemed to be flying very well
at 70 to 80% throttle.
Take off's were great with good climb rate.
However, there is always room for improvement.
That's what it's all about...we do like to tinker.
Andreas
Happy building & flying.
