I acquired a springer with a radar motor that didn't work. About an inch long, 37 dia, with a long 2 mm dia shaft.
Bought a similar replacement but complete with a tiny motor controller board that I hoped would operate from the 5th channel on my Planet Rx. Connected up, the green LED flashed to show OK, but no motor rotation. Various channels tried. No go.
OK, so now wire the motor direct via a switch to a 1.5V battery. Working !
Fitted the motor unit in the wheelhouse roof, as before, using double sided self adhesive mounting pad. Still working.
Whilst fitting the radar to the 2 mm spindle the minutest pressure popped the gear housing apart dropping cogs into the hull !!!
Are you normally expected to glue the plastic gear housing halves together? Appears only a very light push fit together.
Any idea ?
