Hello to all.
I thought always too much over the motor mount. It give so many variants. The most important is that it holds and I can say to myself its OK.

Hello Eddie:
your ventilation is ineffectively at least for the engine or esc. I white not however which you would like to cool . Your modified cooling is good for a Hacker but not for the Pletti. Think about it. Look at the photo of the Evolution. I have only cut my spinner. It is the not beauty but effectiv.
Here are two photos from the motor mount for my Synergy. (Copy by Chad) I think It is perfect for the pletti in my Synergy. This is the only way to build a motor mount for Outrunners like Pletti or Axi ...., with a Backplate mount in a Fuselage. I think the problem for most builders is to build a motor mount that is light and good. But who said this is good or not.
