Here is an update with the Lehner 1930/8. It weighed nearly 8 lbs with the XL motor, now it is a little over 7.5 lbs. I lost 5 oz. of motor weight and the RC-Monster heatsink. More on the Lehner later (perhaps another thread).
That is one nice system you have there, and who's heatsink is that?
Just a suggestion, what if you moved the MM over a bit more on the one side of the motor, for easier access and cooling?
Also, what BEC is that there? I have never seen that one before.
