Greetings,
As I've mentioned, I
recently purchased a Kolb with a 912ULS engine. Since I've mentioned the
rotary engine possibility on the Kolb list, I've had 3 people ask if I would
sell the 912ULS. Now that I find out how much the engine is worth,
I'm seriously thinking about selling it, and going ahead with the single rotor
engine.
Questions:
- Where can I get a single
rotor eccentric shaft? I'm thinking that the only ones running now were
cut down from 13B shafts, which I understand is a mighty tough
job.
- Folks have done plugs-up
engines, but has anyone ever done a plugs-down engine? Do you see any
reason why it wouldn't work as well as plugs-up? Having the
intake and exhaust on top would be the best arrangement, but it won't be
possible to do this unless I can get a planetary drive unit to keep the prop in
the center of the engine.
- What is available for
light weight PSRU's? I know that Richard is using a Hirth gearbox, which
is a good idea. There must be some belt drive units available as
well. The biggest problem is that most of these units that would fit, are
made for a 13B, so they're much heavier than they need to be for a single
rotor. I'd like to stay with a high gear ratio, since I'd plan to
run the engine at higher rpms.
- Lot's more questions if I
decide to do this.
Thanks,
Rusty (could I possibly be
this much of a masochist)
