I myself am mounting mgm controls in both of my rides (losi 8ight truggy and RC8) I will attemp to mount the esc's to the chassis on both in the only spot left (the empty space on the left just behind the battery tray you know right next to the ass end of the motor. I will use a piece of the plastic spacer plate that comes with one of mikes battery trays and screw a small piece to the chassis and ziptie it to the spacer ( with my dremel I will first make some little grooves on the bottom of the spacer to allow the zipties to slide through). I hope this type of mounting will help keep the center of gravity low while protecting the esc from lid landings also it will be strapped to a hard piece of plasic hopefully allowing a little airflow under it rather than letting that bottom heatsink be mashed into a soft chunk of foam insulating it from airflow.
