I did some flying test.

What I have is a hanger 9 cap 232 73". I have on it a us 35cc whit CH ignition on it.. I took out the spark plug and put in my glow.

I did not take out the nicad or the moduel out of it.. I did not want to chang the wight. Took the plane up and I did not see a big difrance in the way the play did, but what I did see is with the idle lower then was it was landing this plan was not the same.

This was not a good test with this plane cuz the plane is light with a big engine on it..

The next test I did I took out the Ch moduel, nicad and kill swich servo. I took off the CH ignition fly wheel and put on a bushing to take up the space.. Then I had to lighen up the tail to get the cg back to were it was..

Went for a flight.. now the diferance was un real.. It was not like the same plane... It took off in about 8 feet and was able to go strate up.. It was nice........

I can say one thing.. Gas/glow is hard to beet... Mixing fuel is a pain but what you get out of it is werth it.
