It is great to find someone so responsive like you As regarding the "freezer" it is a spray can that actually freezes the can from outside, so it makes the magnet cooler ... do you think it helps?

Thanks for the info ... are you in rc racing too? - However I cannot add another cell since it is also againts the rules - As regarding the batteries ... they do tend to heat up when I charge them ... and then peak them again before the race! I usually charge them with 4 or 5 V .... if I charge with 6 or 7 V ... will it give more power? Also, shall I charge the batteries ... say in the morning ... let them get cold (few hours) ... and than just peak them before the race ? OR I make the full charge before the race and race with them still bit hot? - Another thing ... there is a freezer for electronics that will drop the temperature below 0 ... never heard of it?

Thanks YT2095 for your comments. We are using the motor for rc racing and it has to be standard for eveyone in the same class. I am trying to see if I can improve the power in some way. I already have a heatsink ... there is really nothing I can do? If I put another magnet on top of the motor ... will it effect anything?

I need to find a solution ... without opening the sealed can (motor)! - If I use the electronic freezer ... will it help? - If I put metal surronding the can outside? - Any comments or suggestions? Thanks everyone .......

As regarding sealed electric (21 turn) motors ... How can I increase the strength of the magnet and thus power of the motor?
