thanks arrow =) I'd sure be glad to help, but I guess I don't really understand the q =)

15oz of thrust works out to be 425g of thrust, which would be really good for the stock cpp at 298g. My current heli is about 360g, so I dunno how much performance it would give for mine, but it might definately be a step up from the stock motor.

I would also be very interested in a motor with ball bearings and replacable brushes. The main thing I think in these motors to look at is how much juice they draw and seeing how close it gets to over doing the heli. When my heli was flying well I was using about 4A so the stock battery would last about 12 min. I do wonder about that first motor that says it only draws 1.2A of power. Off of the testings I have with the sym blades on the cpp at 5k feet with the 9t pinion the stock motor draws 1.5A at 0 pitch. Also the stock motor as I weighed it is 49g, so they are real comprible in the weight section.

I've been trying to figure out how you calculate thrust, so then we could compare the motors that way and maybe find out some more stuff that might be helpful.

On the brighter side, I went by harbor freight today and they were having a sidewalk sale =) wahoo! I got 2 multimeters for 6 bucks =) can't beat that!

I got them for the heli bag so I don't have to beat up my nice one. Heck at radio shack you can't even come close to buying the leads for the price I paid for the whole meter =P I guess we'll see how it works out and if it is very accurate. I've got to figure out how to run the transistor test function. If anyone knows how to do that, I'd really like to know =)
