Hi, I have a Mugen MRX4 just sitting around after I bought my Motonica P81.
I was planning on making something close to what you have come up with, biggest question is the battery. What lipo battery are you using?
I was think of using this one: http://www.hobbyking.com/hobbyking/s...5C_Lipoly_Pack
Also I was thinking of placing my MMM just in front of the motor, on the upper deck. Any weight balance issues? Does this explain the location you have used?
Any help and feedback would be appreciated.
