If you think about it, one reason the bevel 20z is useful is that in the A model it might be used for horizontal transmission while in the B model it might be used for perpendicular transmission. However, given the death of B models, there's really no need for the bevel gear unless it is needed exactly in perpendicular transmission in the A model. The Airbus still has at least 1 black 20z bevel gear, and it is used exactly in perpendicular transmission.- 5,513 replies

I've finally solved the last problem with my PF mods. For some reasons I still don't really understand, with the PF mod, the model can move forward with reasonable speeds, but really struggles when moving backwards. I figured the problem is inadequate torque, and after a series of attempts, I finally found the way to gear down the motor. The ratio of the new design is (12/20)^2*(16/20)^3, or 0.18:1. The model can move backwards on both tracks now, but still slightly struggle when moves backward on one track. However, I think the most recent setup is the most optimal within the space constraints already. Updated instruction is coming soon.

Apparently there are two switches on one side and one switch on the other side. According to the stickers, one switch will control the winch function, but there are two winches in the model. Does that mean both of them are connected to the one switch, or is there another switch somewhere that I missed?
