Charley, if anyone wants to run a planetary they can. I can only advise that Powersport tested them and had problems. Mostly backlash caused. Niel may have a good design. Good luck to him. I have no product to sell, and no personal time with all the other designs. I’ve had discussions with several people who have had problems with planetaries original Powersport guys included. If you have a good solution tell him.

Bill, I know you have a vested interest in getting the Powersport design out there, and  I realize that it seems to be a basically an ok (though quite pricey) product (with no current production and apparently no support).

That does not justify advising avoidance of designs that have a far more proven track record than the half-dozen or so Powersport drives that have flown.

Mark, there are a few Powersport units available. They will handle the power of a 20b. Not a planetary. Avoid planetary units other than the fully custom unit done by Mistral.

Who is making a 13b fit 3:1 planetary now-a-days? That is since I can’t get a Mistral unit! Need for a 20b.
