Re: Gear Drive Question
The ratios don't work out exactly for that setup - 35 times 3 is 105:1, not 100:1. It won't be the most efficient way to get power from both motors.
Is there any reason you can't use the 2 motor VP adapter here? This seems like the perfect application for it, and it would take up less space.
Alternately, could you make both gearboxes the same ratio, and use 40 tooth gears on each to mesh them together? It's the same center to center spacing but no weird ratio combinations.
You could also use a single 775Pro for almost as much power as 2 BAGs. Any number of other solutions seem more robust and reliable than this one.
