The motor linked to above is rated to 70A which should match OK with the 100A SC. In theory this would give 1920watts (24v x 70A) which sounds enough to machine wood. The actual amps pulled (for a given motor) will depend on the cutting load, but I'm not sure how easy this is to calculate. If you pull too many amps during the cut the SC will probably pop.

For this reason myself and other model aircraft users often use an ammeter to check the current draw on the ground for a given prop to make sure all is well before the first flight. If the SC gives up in the air, since it sometime also powers the reciever you loose the plane.

You could do the same thing for the first cuts to check your safety margin.
