Of course, you've also had conversations with guys who've had problems with the Powersport drives, including the original Powersport guys who trashed one in the Sun 100. There are other authorities on the subject of reduction drives who have other perspectives on why the PS guys had the problems they had with planetaries.

Point is, none of these things are going to be perfect; even the RWS drives have relatively low total hours compared to things like certified engines flying on tens of thousands of a/c designs over many decades.

You made a blanket statement that no planetary except the Mistral is worth using, yet you have no experience with any of them. Why are you so passionate about an issue with which you admittedly have no 1st hand experience? If the RWS drives are so terrible, don't you think there would be at least a few people who are active on this list and have hundreds of hours flying them who would speak up in agreement with you?

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.
