Using the central motor mounting posistion on the 3905 tranny, I dont think theres any improvement in the CoG, but using the offset posistion would bring the motor right down low for sure, albeit to one side. The tranny gears are beefier, and the slipper is better (I use that word with a touch of cynicism as my 3905 slipper conversion broke when I tightened it up- the slipper pad holder just snapped because its cheap pot metal), but I dont think theres too much to be gained from switching over trannies really...
