Action: Those numbers are Fantom number, not Robi or CE turbodyno. What I have done is use the Reedy 769 brush (767 w/cavity) and green (+), blue (-). or tweek springs to 6.5fs (+) 6.0fs (-). If you want I will post my TD numbers tonight when I get home.
Louis B: I just started myself
Been working on the "boys" to get them to run the 1/12's. As we move to a new facility in 3 weeks people are draging their feet till the new track opens. I have an advantage as I am one of the ones laying out the track options. So if I lose I can blame the guy that laid out the track LOL
P2K2 is a good cross between a GM3 and a P2K. Can's are the same, the P2K2 arm has 2 less laminations than a P2K. That is from Big Jim, designer of the P2K.
I have 3 motors tuned for 5v and 5 motors for 7v. I run stock TC. My favorite motor is the P2K. In order of preferance; P2K, P2K2, Hellfire w/766 narrowed brush, GM3. I prefer torque with my motors.
Brushes: 4499's make good power, but are designed for coms .275" or less. To use these rub the tips on a flat formica top and wear down the tips slightly. Reedy 767 work just as well, but are easier on the comm. 766 is a torque brush, 769 is a 767 with a cavity and 768 is a 767 with a vert slot.
