          two BL motor on a single ouput tranny will require to use a one way bearing on each motor shaft, same as those use on RC heli for autorotation, but as others said a lot of engineering is needed to put this together!
          The only advantage you could get using a tranny, is to swap gear to change ratio, nowdays with the available range of motor (size and KV) this is useless and IMO just another source of failure.

              Most of us are aware how they should work

              I'm not looking to build one, I am looking to see if such a trans is out that can use XL motors..

                i told you before the emax (old 3906 style) would be easy to modify and everything on it is balanced and centered and is made to hold 540 motors and is heavy duty

                  Mack Products make them. They're shown with motors but I'm not sure if they sell the gearboxes seperately.
                  You would have to check with them if they could handle the power & revs you are planning on using though.


                  Thinking about it though, you probably don't want a reduction gearbox just something with the two drive gears & the shaft gear all the same size. I guess that depends on the kv of the motors & the voltage you intend using. Just a thought.
                  Cheers.

                  See the danger. THEN DO IT ANYWAY!!!
