megabyte, that that was what I asking. The tool I was going to build would give me a reference point to start from. I assumed that I would have to adjust from there. Right now I'm working on the 4 motor/2 battery AA. I destroyed a rx it appears, and have to decide which one is next on the hit parade. I will have to get voltages from the rx to the motors to make that call. I'll post the numbers.

Gtx, I have been threatening to buy some softair guns to knock down the planes for monthes. I guess it comes down to the accuracy of the gun. BTW, the corps certified me an expert rifleman, I'd love to to the qualifying thing again. Tim
