Soldering 25D Motors

22 AWG should work just fine for beetle drive, what problems did you have? I use 24 AWG in The O'Neill.

You haven't described what issues you had soldering the new wires, so I can only guess the large thermal mass of those chunky 12 AWG wires is sinking too much heat.

I should just quickly correct myself, it's 14AWG not 12, I'd gotten mixed up!

Thanks again Cosmin! Absolutely sure it's the wires, the lid was off and they were glowing! Probably just dodgy wires. As for the silicone suggestion, we're going to move over to Turnigy Silicone insulated wire instead. The Pololu 25D motors we are using have a current draw at stall of 5.2-5.4 I believe so I'm really not sure what could of happened short of terrible wire quality!

Thanks for the advice though, I'll give it a shot with some #22 AWG wire from Turnigy and hopefully be back in this thread with the results by Sunday. I had no idea about silicone insulation so thanks for that bit of advice!

I think you must have had a short somewhere then. They would have been hotter than 500 degrees C to glow.
