..(this was the thread about the [FlyRotary] Re: Rotary - FWD from
Lancair ES List )..
Here's info for a rotary installation comparison if Tracy can recall his
last W&B on his RV-4. Tracy, how does your plane compare to
this?
- My RV-4 is bone stock VFR with lights (think J3-with-a-speed-kit)
first flown in '96.
- Lyc O-320 E2G, 150 HP, 2 mags, carb, no vacuum system, one radio and
transponder
- Sensenich FP metal prop with 2 2" spacers (41 pounds total for
prop & spacers)
- That big stock boat anchor starter
- Heavier than necessary 10 ply tires (extra 6#) because they were on
sale.
Empty weight 979# with 48# on the tail wheel
Empty CG 69.25 inches (using the 60 inch datum)

13B in gestation mode, RD-1C, EC-2

It varies a lot depending on
builder choices but I would put it closer to an O - 320, a 30 - 45
lb difference depending on which of the many versions of the IO - 360
that Lycoming made). The counterweighted crankshaft on the angle
valve IO-360 (200 HP models) accounts for a 28 pound increase
alone.

- Hennie,
- I?m told the 2-rotor will come in about the same as an IO-360
installation. This is a very common install in the RV-6, also in
the RV-4 (Tracy Crook). If you?re really interested, you can get
onto the Fly Rotary group. Good bunch of guys and they will be able
to answer any question you may have about the rotary.

- Hi Mark and
anyone,
-
- "
Mazdatrix recently
dyno?d a N/A peripheral-ported 13B for Paul Lamar at 250hp @ 6000rpm,
running a carburetor. That is an easy 125hp/rotor, and 250 hp from
a 195# engine."
-
- What would be a
reasonable firewall forward weight of such a N/A complete installation?
What I really want to know is what is the lightest installation to be
expected based on average experience?
