i run the 10xl 9920 and get a good 25 min run time goin mach two most of the time... ib3800's 14 cells, if i bash more i can get about 28-30 min

Is there any other motor that would be better than the 9l or 9xl under $100?

Not that i can think of!

WEll you have a choice of a 10L and stuff to. 7xl 8xl 10xl You have a wide variety of motors. It would depend alot on you application. what you expect out of it to. I think the 9xl was my favorite motor until I got a lehner 1950.

sorry i forgot to metion that sylvester ran somewher along there. but in his basement:025:

30 mins ? Hah, more like 50:)
