PostSubject: Need advice on motors!   Sun Feb 24, 2013 6:04 pm

I am new to robot building and I'm putting together a robot for the NRL. Need help in deciding what kind and size motors to use. We have some old parts from past robots. We are using 14.4 Volts, 5000 mAh battery packs. The motors that we are using for the drivetrain seem to work just fine, but we are having trouble with our weapon. The motor we are using for it doesn't spin very fast. We need something that has a pretty high RPM, but also a little bit of torque. Price is not an issue, so any advice would be greatly appreciated. Thank you in advance.

Cody, thanks for the suggestion. Maybe you can clarify a couple things for me. I don't know if we need a new ESC. We are using the WASP ESC, which seems to have enough capacity to handle just about any motor we throw in there. We are using the Spektrum 6 controller and controlling the weapon through the left joystick on the controller right now, our biggest problem is that the motor we have is off an old kit, and it's got a lot of torque but only pumping out about 300 rpm. I was thinking we could just swap out the motor for something better. Any suggestions on motors, or should I focus on looking at the Castle motors?

You need to go brushless for your weapon
