Was busy working on my 1717 6s Slash 4x4 and didn't have much motivation lately to work on the twin, but now a little update.
Cut down the motor plates so that the top plate sits lower and made a top plate for the diff/motormounts from 3mm CFK. Did not turn out very nice as I was too impatient, but it should serve it's purpose.
florianz: Found the project with the two Medusa Motors from RON2. Looks much more nicely done than my project. But my project is clearly ahead when it comes to power/weight ratio :)
