Paul,  Rotamax has dropped their old "aviation" oriented web pages.
Instead, all you get now is a single page with a picture of a rotor  on
it and an invitation to e-mail Eric for more info.  I, of course,
don't have any knowledge of what is happening but I would guess that
multiple problems appeared as soon as they tried  aircraft work
loads.  They derated the engine until it was not competitive with a
whole list of recips.including Rotex, Jabiru, VW, Suburu and Suzuki.
What a shame for our movement.       Jerry

Not the first time. Rotaries are harder than they look.

Paul and Jerry,
I would like to know what the primary problem was, I did warn them of
possible wear surface failure without sufficient depth to the Al wear
surface coatings.
Perhaps as Jerry says, maybe the high end work loads took their toll.

So would we all.

Once the "problem" surfaced, RotaMax   immediately tried to cure it by
limiting  RPM.  In this context RPM = Heat.  So was the rotor getting
too hot or perhaps the coating on the sides was coming off in chunks
(my imagination).  They knew the problem but no solution was to be
found.  They should have taken Paul's advice which was to go to oil
cooled rotors and scrap the charge cooling.  Funny thing is they had
the equipment to do that but perhaps not the engineering ability.
Your comment about the coating's thickness is interesting.  I
examined  the the end housings at Sun n Fun with Paul.  I could not
detect the coating at all. It was probably only a couple of molecules
thick or maybe it was just vapor.       Jerry

Jerry,
They said they had 'you-beaut' coating but neglected to say what that was -
always makes me concerned. Perhaps those display end housing were uncoated?
