This geardrive offers powerful performance with a 20mm motor. With a spur gear which has just 35 teeth, it also gives relatively fast prop speeds compared to most other 7mm geardrives. The unit is supplied in parts (un-assembled) so some construction is necessary. The motor is a smooth fit in the housing but it will still require some glue to secure it in place.
