Weight as shown is 11.2lbs
Ratio shown is 7.46:1
The propulsion shaft is from a Cimplebox...so the propulsion encoder goes underneath. The main mount plate has the features for mounting a US Digital encoder.
The steering has some features for mounting a sensor, but the Versa shaft needs to be modified to use them. The unit shown has no mods for a steering sensor. The customer will supply their own.
