That's OK, I know what you mean. It's tough enough to get things exact even with the test parts without trying to guess from pictures.

Ok, OK, I was a little incorrect about the motor length (must have been thinking of a different motor). The XL can is 74mm without the wires. Add in the RCM heatsink and the length goes up to ~79mm. Although about 3mm of that extra 5mm is the end clamp, which is not very wide and not likely to hit anything. Still, you can see from the pic of my truck that the end of the motor is quite close to the suspension arm and my motor mount is as close to the spur I can get without hitting the slipper adjustment screw. I'm using the stock blue chassis.

About the motor support; I don't think flex is an issue during normal driving, but when you take jumps, there is a fair about of weight (motor) that wants to drop when you land. Aluminum does flex and if you are on the throttle when it's flexing, the mesh isn't perfect. For support, I was thinking about wedging a piece of firm rubber between the mount and the motor. I'd probably shape the rubber so it fits the contour of the motor can. The only other place to support a Feigao/Wanderer motor with a bracket would be by using the RCM heatsink clamp screws and I don't think they were intended to be stressed in that way.
