In the mean time let me tell you that the RE5 is a single spark plug

engine. It has

peripheral
intake and exhaust.The power takeoff is via a double roller chain sprocket

close

to the
counter weight. The sprocket slides on to the shaft and is driven with a

hefty

woodruff
key.Behind that are all the accessory gears. A large nut holds the lot

together.

Thanks Erwin,

Powersport style. It strikes me that the peripheral ported rotary has been
been rather neglected, because it gets banned by every racing category it
wins at (all).  It would seem a much simpler solution for an aircraft than
adding a turbo (unless you need the altitiude power.

Conventional wisdom is that PP Rotary can hardly idle, poor drivablity yada,
yada ... Yet here is a PP single rotor that had a very good reputation for
drivablity (one of the few good things you hear about RE-5's). Is this
related to engine size? A smaller rotary being easier to PP without getting
lumpy?  The RE-5 is not much smaller than on 13b capacity-wize. Most 13b PP
experience seems to be aimed at developing horsepower, but it would be
interesting if you could use it to develop the same 180hp but adding
simplicity.  Could this be done without the throttle butterfly in the
housing adding complexity? Small ports?

Nah. All that stuff has been over rated. Putting the butterflies near
the peripheral port solves all that. I drove a PP NSU RO 80 with a three speed
manual transmission and it pulled fine and idle great. Carb no less
with the butterflies upstream of course.
