oh for sure its legal to use banebots transmission are legal as long as they are ones you bought on the website!

Nice looking design, are those motors used for an arm type device, those look like pulleys to me, belt drive maybe???

Looks like the 973 version of the Beach'Bots favorite arm drive. Maybe they did it this way to make powering the arm easier? (On the stock FP output, you need some sort of adapter--usually an octagon--to drive a sprocket via a shaft.) As such, I would say chain drive, two stage reduction to the top.

I would agree, 2 stage reduction appears to be consistent with the render here. I'm not sure if it is all chain though or a belt and then a chain as the bottom circle in the render doesn't have any teeth.

EDIT: although that doesn't mean a whole lot, I would guess it's far easier to draw the gear like that if you are making it yourself and not using a premade file.

I knew the transmissions were legal, but the motors all look the same (I was thinking that maybe they were planning on the mabuchi motor from last year)

Reminds me, I have to get someone to fix our motor tomorrow because our driver burned it up when he refused to listen to me. (Released the magic smoke, lots and lots of magic smoke)

They are FP motors into 64:! planetary gearboxes.

FYI; eric has been entirely right with every single one of his responses/guesses in all 973 threads so far. I'd take his word in future ones.

We used the Banebots gearboxes because they were much easier to mount and interface. We made sure to stay away from the higher reduction models though.

Just remember, I was on 330 during the 2005 and 2007 seasons, when we used this arm design...

Our favorite mounting tactic was to position the hole for the axle of the stock gearbox in such a way that the flat portion of the gearbox was against the mast section, then use an octagon in the output to finish holding it and then hose clamp the output around the octagon. Hey, it worked.
