CD ROM Motors

[Neil McGrath]

I spotted a set up on Ebay showing one of these motors and wondered if anyone had tried one in a small fast electric boat, as a replacement for a Speed400/480.

I looked at doing it once, Neil, but they have very low Kv (the ones I looked at). For a scale boat they would be fine, but the ones I saw don't really wind up the way I'd like for a boat. It probably depends a lot on the boat and the motor.

This type of motor has HIGH resitence and can not be cooled effectively, even the large motors have a MAX. amps of 40 making them unsuitable even for offshore.

At the SAWS in fl, rumrunner set a record with an outrunner:cool: I was impressed, it was a 6 cell mono. This was my first meeting of the RumRunners and I was very impressed with them. Nice to see father and son setting records:D Thanks for all the help and info guys....MJ
