You're right, the motor mount is from hm-modellbau (onefive.de).
Michael, the owner did a hell of a job to support me in realizing this Monster-project.
Do you have graphs of the runs to see how many AMPs you're pulling? I just want to get an idea if my 10S ESC will be enough or if I have to get something more powerful done.
The maximum temps so far have been 140° F at the ESC and 120° F at the engine at 50° F outside temp .
It is a 4WD monster out of the box. I haven't checked your rules regarding links yet but if it's not a problem I would post the link to the construction manual here.
The KV rating in the current setup is 875, the shaft size is 10mm.
10mm is the regular shaft size of the 1/5-6 gas-models so pinion gears are no problem.
