I just did an upgrade for my buddy's mcpx v2, exactly the same setup as mine.
I really thing this M5 motor complete the mcpx. It is much more powerful
than stock motor. Works with stock tail and smaller battery. It can do pretty
much all the 3D maneuver. http://helifreak.com/showthread.php?t=384245
It works with V2 as well.
Because it is the second time I did this upgrade. Now I can make the process
Here is the parts:
There are many different way to do it. Here is how I did it.
First thing is put the pinion on the M5 motor. Because the M5 shaft is only 1mm,
it is very easy to bend. I drill a 1.5mm hole on a wood board. Put the wood board
on the back of the pinion, then use the vise to press the pinion on the shaft.
Let the shaft go into the hole in the other end.
