J concepts honeycomb motor mount
is a total sleeper upgrade. i was using the lightweight milled kyosho upgradea, but at 2mm thick, i felt like it flexed a lot. plus when my motor was hot, the plate was barely warm. i noticed the jconcepts was 3mm, so i got it on my last amain order. does not flex everytime i tighten pinion or motor so winning. but why its totally rad is because that honeycomb design does a kick ass job at dissipating heat. my temps have been 10 degrees cooler and i can feel the motor plate is almost hot (compard to warm), doing a nice job with the heat. the only thing i didnt do was weigh the piece to compare to the kyosho one. but i doesnt matter. 20 bucks well spent!
