By comparable, I mean 4 stroke, with a long TBO. 2 strokes ain't comparable in my opinion.

Even though the rotary acts like a 2 stroke as far as rpm, doesn't it have fuel consumption more like a 4 stroke. Sounds like you get 2 stroke performance as far as weight to power but you get fuel consumption like a 4 stroke and you don't add oil to fuel plus they run smooth as silk. If these things are true, then double the cost of a rotax 2 stroke sounds like a good value.

Also, on the fuel consumption subject, my old Cuyuna in my Pterodactyl was always pretty easy on fuel, but the fellow I sold it to replaced it with a 440 Kawasaki with the 4 V-belt drive from J-bird, I think the whole package with engine , belt drive, exhaust, and carb was under $950. Anyway, he burns under two gallon an hour now with the Kawi, blows my mind how efficient that engine is on the Dac.

Lean + turbo = broken apex seals. With a computer that will allow you to aggressively lean the mixture for cruise, you can get as good, or slightly better fuel consumption as a Lycoming. As for mixing oil in the fuel, sorry, you still have to. All Mazda rotaries have oil injection, though most of the airplane guys ditch that, and pre-mix .8-1.0 oz per gallon. There's just no other way to lubricate the apex seal.

Oil mix is not a big deal but fuel use is. I had an 86 twin rotor rx7 and I don't remember oil use. I do seem to remember that I was told that it would consume oil but I don't think that I had to add oil in betwen changes. Is the aircraft application different or was there just a minor amount of oil consumed from the crankcase in the rx7? Anyway, I may want to try one on the floatplane in the future. You can always stay over your runway if you have a big lake.

It's very forgiving of mixture, and I think the overly rich settings on the early carbureted versions gave it the gas guzzler reputation that I hear repeated over, and over... The 85 RX-7 that I had was OK, on fuel, but didn't have that much power. The modified 93 twin turbo was another story :-) With Tracy Crook's engine controller, you can use the mixture knob as almost a second throttle. Just leave the throttle at max, and adjust power with mixture. The range is huge, and nothing like you've ever experienced in a piston type engine. Oil consumption for the apex seals is very low. Best I recall, my 85 manual said that you should not have to add more than one quart in 1500 miles. I used to change my oil at 1500 mile intervals, and never added in between. As I mentioned, we tend to run 1 oz per gallon, but that's too much. The excess oil tends to get scraped off the side housing by the oil seals, and it goes in the sump. In almost all of our planes, the oil level rises, rather than dropping with usage. People are finding that .8 oz per gallon keeps it about even. The problem with the Mazda system is that it uses 4-stroke oil from the sump, which is not intended to be burned, so it ends up gunking up the rotors. Of course Mazda knows this, but they know that no one would buy a car that had a separate reservoir of 2-stroke oil to fill. They also know that people would forget to fill it, and cause engine damage (wears out the apex seals, but nothing catastrophic). Richard Sohn makes an adapter that allows the stock Mazda oil injector to draw from a separate reservoir, which is really the best of both worlds. I may one day change to this. Richard is also the guy who's made the lightest single rotor to date. Still under development.

Also, a two blade 66' or 68 ' would perform better I would think. The three blade should be smoother.

It was a wonderful running engine with zero engine problems in 8 years and 90k miles. I talked with the people today in Canada and we may do a factory test of their engine. Look forward to your input in the future. As soon as I rap up the current Firefly on floats and get through Sun n Fun I will get started.

Subject: Re: Kolb-List: Rotary engine ... --> Kolb-List message posted by: "Bob N." My '66 NSU single rotor Wankel initially used about a pint/1000mi, deteriorating to a qt before replacing the carbon apex seals. Later my twin rotor in the RO-80 used a qt in 1500-1800 miles, but it was driven hard. The German translation for the oil metering pump is dose, like a dose of castor oil. Surely would like a single in my FireFly. Bob N.

The reason for the sale is that we are selling our place in Discovery Bay (San Francisco Bay area) where the plane is located. It was very convenient to service and fly it from the water during the summer months. During the wintertime the plane was stored in the garage and never exposed to inclement weather. It is currently in the garage with the wings detached and tanks dry. It has new sparkplugs installed and the oil and filter changed. I am asking $19,500. If required as a condition of the sale, the plane can be assembled and test flown from the water with a few days notice. I am willing to sell the plane separate from the floats with the original Kolb wheels installed.
