Thanks YoDog,
Will try it next meet!
Capt'N_Slow,
I ended up removing alot of material from the stock plastic tray... I use the front layshaft mount to stop forward movement (after grinding off the front lip of the tray) and then trimmed the back to suit the lipo. I had a Kfactory centre brace that mounted on the bottom of the upperdeck... I had to replace that with a plastic one that mounted on top to get the clearance with 2mm spacing (did not want to space it any higher).
It seemed like alot of work at the time but its well worth it. Very secure.
Hope this helps...
