Re: Wheel shooter gearing
With 8" wheels you definitely want to gear the motors down. How much to gear down will depend on your configuration and desired range. In our experience single axle/hood shooters need to be geared 1/2 as much as a dual axle shooter to achieve the same distance. In other words, a single axle system has to spin twice as fast to get the same exit velocity.
For reference our design uses two 6" wheels on a single shaft with a hood with a 4:1 reduction using 2 FisherPrice (0673). We can shoot from the key and forward without a problem.
