Cheers Pat, good indication.

1. If you want to run these motors, you probably have to get a better board/ESC that can handle the current. Email the people you bought the motors from and ask for what recommended tank electronic to run them. Ask for the motors continuous current and peak current are also useful to know.
2. Use old motors or get motors with current that matches your board motor controller. For example, these promax 480 motors (ACC348) draws only 12A max and they are very strong. (http://www.maxxprod.com/mpi/mpi-10.html)
By the way, what electronic are you using?
I emailed Tank Army on eBay (Where i bought this motors from) based on your point # 1 above.
I'm using pretty much standard board and controller. Though i do have CLARK board sitting in a box untouched, just because i take my sweet a*se time to get another controller... i think i'm more like "Use it till it dead, then consider buying another to replace" basically use it as much as i can before getting another.
Im not sure if ClarK board can handle these motors though? maybe its time?

It does say they come with cable for connecting to RX18. Perhaps they can shed some more light on it for you.
Hey Mate, yeah i emailed them already to see what they can come up with

Yours might running really hot if this is the case. Temp can rise pretty quickly & the FETs can cool down pretty quickly too once there's no load.
. i'm using Version 2 board of HL "2.4GHz Multifunction Unit For Heng Long 1/16 Tank VERSION 2"

THanks guys for your help. Will keep this post posted. Cheers!
