There's also a 42mm version I've been looking at for smaller stuff, though I might upgrade to 45mm.
For teams wanting to do this or something similiar, make sure you only use the low-power RS775-125 that Andymark sells. If you try to hook up a 775pro or 775-18 it is not going to end well for you. Andymark says on their website that if the pg27 with a 9015 is stalled then the gearbox will break. So even a reduction as low as probably 10-15ish:1 with a decent 775 will cause failure of the gearbox. In comparison the Versa-Planetary is rated up to 210:1 for the 775pro. So the gearbox can only handle 1/20th of the torque.
