If anyone can do it, it is them. They VERY RARELY Have a 90* Turn in anything they build, instead of having a horizontle shaft going to a vertical shaft they use sets of planetary gears, very little parasitic loss, and much, much stronger than a set of beveled 90* gears. Thats why their cases always look funky, but very functional.....
