Just thought I'd stick mine out there for comment...
A couple of "unique" things...
1) I used a cut down pede chassis for the battery tray - light strong and holds my 2 X 4000mah 3S Maxamps really well.
2) I found that a 40mm brushless PC fan fits perfectly under the teckno wing and just provides some extra air flow.
The mamba is holding up fine with 9XL on 3S geared 24 / 65 - I have an external BEC to help keep it cool.
Transmission was beefed up with the robinson slipper and dual metal gears. I kept the two speed using a 2060 micro servo mounted on the normal motor mount.
I'm using a Spektrum so no interference and means I can keep all the wiring inside.
