fitting a fan to the motor wont do owt, you need to fit a fan to the esc as thats what does the work now.

It's probably more the speedo thats going to get hot I would think.

thats where my second problem comes in, i have no way of cooling the speed control within the limits of the chassis and shell space [if that makes sense] i have no space to put a fan on the speed control as if one were facing across the fins of the heatsink then it would stick off the side of the car, if one blew on the side of it then it would make no difference.

Put the reciever on the top deck? I managed to get a KO reciever, Quantum 2 and a 35mm fan blowing at the motor between the back of the servo and motor endbell no problem in my origonal BJ4.

i'm not having that, i've just squeesed an mtroniks genesis pro in to my bj4, and ive even fitted a fan on top of it - and it still has the big power cap fitted.

If i can fit that, i'm sure you could get a 2007 in yours, even if it is an original car!:p

right, ive got the reciever on top deck already, i have a normal size servo, its just the sphere is so tall, if i put a fan on top it will obstruct the shell, and it is facing the wrong direction for me to fit one pointing over fins of the heat sink, so i dunno what to do, as if i turned it round, the wires wouldnt properly fit and the board with the wires soldered onto would be nearly hitting the motor. i would put up a piccy but im embarrased with the motor soldering, haha

o yeah, and rich, the fan could fit there but then it would be blowing into the side of the speedo and heatsink, not across the fins

okay, i think i have it sorted. now i just need someone that is good at soldering that can make a good job of my speedo to motor soldering... anyone offering?? :D

Yep, a bigger spur is the hot ticket here my friend! :cool:
