MP Jet gearbox for Graupner Speed 480, getting closer


Still hunting for the 480 gearbox that Ripmax calls for in their Alliance kit. I have contacted MP Jet, they referred me to MacGregor Industries in the UK. I spoke to a rep at MacGregor, they acknowledge the existence of the gearbox, but they have not actually received any yet. Below is a picture of the gearbox with the motor as sold by Ripmax . . .. .

Looks a lot like the sp 400 MP Jet gear box I got from Hobby Lobby. They have some for 480's too.

The gearbox as supplied by Ripmax is exactly like the MP Jet gearboxes for the speed 280 and 400 series motors, but Hobby Lobby does not carry the 480 size. The Graupner 480 can is larger in diameter than a speed 400 and the motor shaft is 3.2mm in diameter, not 2.3mm. There are two gearboxes sold by Hobby Lobby for the Graupner 480 motors, both are inline style.
