hey guys I guess we can use some stuff that aviators use for their rotaries in our cars. Check this site out www.rotaryaviation.com

There's a OMP that can be used to avoid premix, it actualy puts 2 cycle engine oil into combustion chambers, you'll need additional oil tank for that

Sweet! Thanks.

interesting

only $3500 for a 20B

MY EYES!!! ITS GOD!!!!!

Those are FD rotor housings. Nice touch, they have bigger exhaust ports.

Too bad they mispelled his name.

Nomad

You are welcome !

Glad you like it

I'm gonna build a kit plane with rotary engine in it
working on my private pilot license now

Rotaries rull!!!
hehehe

Aviators got lotsa stuff figured out...
I guess their 20b engine is a sweet idea... wonder why automotive guys didnot do so well....

Evil Aviator

Yes, but there's lots of stuff that we haven't figure out yet. IMO automotive guys tend to do better with real-world solutions because they can try things out without much concern for FAA inspections and paperwork, or falling 10,000 feet to their death if the engine explodes. As you can probably tell from your initial aviation training, aviation types tend to do well with theory and "thinking outside the box", as they tend to be mostly Type-A personalities and aviation training is more strict and more in-depth.

I think that's just for the rebuild.

How can you tell with that picture? Granted, the oil filler neck isn't from a 20B, but that can be changed. I've never worked with a 13B-REW, so I don't really have any reference to go by. Is there some physical difference in the housings that I'm missing?

mazdaspeed7

2 plugs per rotor. Correct me if Im wrong, but all of the cosmo 3 rotors have 3 plugs per rotor. I never have seen a 3 rotor in person, but from what Ive read, most of the builders in the country use FD rotor housings on them due to the bigger exhaust ports and only 2 plugs per rotor.

RETed

Uh, no.&nbsp All production rotary engines by Mazda are two plugs per rotor.&nbsp You're thinking about the R26B (or 13G?) which are racing engine.

Nice link, Node. It's good to know that we're not the only ones **** disturbing with Wankels under the hood.

On the other hand, my father's a retired test pilot, and he and his buddies had a special nickname for kit planes...

Flying deathtraps.

I'll stick with four wheels and *no* wings.

I'm starting on an "experimental" aircraft... the ORIGINAL had a "rotary" but not what WE think of as a rotary... I'm building a 87% Fokker Eindecker replica. PROBABLY will use a "chopped in half" VW for power, and it's going to be a legal ultralight. No license required, although I DO have over 40 hours toward my license.

mazdaspeed7

Oops.

Nomad

RX&_ragtop,
hehehe... I got 6hrs under my belt already
I get nervous on crosswind takeoffs and stalls also my instructor is cool guy but even he gets pissed in a while
Tommorow is another flight - I fly almost evereday for an hour.
So many things to keep your hands and brains on ...you look at instruments and let go off controls, start dessending or climbing... well so much to get used to ...totaly new feeling...

Evil Aviator,
but we can build reliable and conservative rotary as aviators do without too much power stuff and be happy with daily commuter.

I was thinking of adapting 13b to natural gas as it cheapest fuel in my country and I believe it equals to avgas. Maybe ceramic apex seals are worth the money considering options of less wear and better detonation handling? Having liitle over 200 horses under a hood of a small car is not a bad idea as a well as running on natural gas which gives better emissions compared to gasoline.
My company is involved in oil well repairs and we have oil well workover units which measure engine time by hours and I've read rotaries so far can have way better work-use time compared to reg.diesel engines. I'm looking forward to see multifuel low rpm and high torq rotaries which can be fitted to those workover rigs. Would be a very great retrofit. Given the price/realibility option to be very competitive with reg.diesel engines.

Nevertheless I'm gonna have 13bt in my kit.plane guys Mine 's gonna be STOL (short take off and landing) plane so in case of engine failure I'll just glide to the ground (don't wish to happen it actually, I get scared when I have to put throttle to idle during my training in the sky)

Good holidays,

The 3rd hole is for the knock sensor, one per rotor housing. Hehehe, I actually have a 20B (obviously), and I can't tell the difference in that picture. RETed also has a 20B, but I guess he couldn't tell either, or otherwise he would have said something.

Aha, a ROTARY RADIAL!!! What's up with the 1/2 Vee? How about a 1/2 Wasp? Just kidding, that 1/2 Vee will probalby give you better hp/weight than the original, hehehe. Man, those scale things scare me. So what are you looking at; 50 Vso and 60 Vne? Well, if you have to dance on the edge, then you may as well do it in a really cool a/c like the Eindecker. Since it's an ultralite, I assume it's an EIII with the larger wing? Geez, with 40 hrs you should be nearing your checkride.

So have you found yourself pulling back on the steering wheel of your car when you go uphill, and pushing on it downhill yet? How about adding gas (right pedal) when making a right turn in your car, and letting off the gas or pressing the brake or clutch (left pedal) in a left turn?

Actually, my mechanics don't let me touch the aircraft engines - something about the a/c ending up like my car. What's up with that? You are right, aircraft engines are nice, conservative, low-rpm reliable transportation. That's just too boring for the street. I was actually thinking about running my 20B on H2 later on down the road.

I don't do that yet , but once I was driving back home and was just cruising the raod as crusing in the air and totaly ignored a red light...oops ..good thing my periferal vision is ok and I spotted a car coming fast on my left...BRAAAAKESSS!!! damn was so close to accident

I do though many wrong things in aircraft . Push throttle in when I need to reduce power. And ***** I hate 3 rpm related controls carbheat, throttle, mixture... (contant speed prop control?glad don't have it . I guess I need another 10hrs before I start feeling quite comfy being in a plane and piloting it.

Long time ago a saw a cartoon, where a pilot was standing a side of his car which was wrapped around a tree...police officer at scene, etc. ...Pilot answered that he tried to pull steering wheel...

I'll be flying a lot when I get my kit plane together over there in my country, cause it freaks me out when I have to go on 4x4 every week to oilfields on 300km trip of bad roads

Flying my plane...(in total absence off small general aviation in my country) And giving chicks a ride to remote beaches of Caspian sea.. mine is 4seater..and 3 girls along not a bad idea

Best of all
Nomad

Evil Aviator

Yes, STOL comes in very handy. However, "real" pilots can hover.

You'll get the hang of it. I didn't feel comfortable until I had about 20 hrs. BTW, you will soon find out that just because you have a lot of seats, it doesn't mean that you can fill them and still fly your flight profile. It's called weight & balance. So, I guess that the girls are going to have to fight over who gets a ride.

Will you be able to get some flight time by flying the pipeline for inspections, or are you just going to and from work?

RETed

Oh, THAT extra hole! Yes, the 20B has an extra bung over the trailing plugs for knock sensors.&nbsp The stock 20B ECU has inputs from all three knock sensors from each rotor.



-Ted

Evil Aviator

Hehehe, I meant that I figured that you couldn't identify 20B vs 13BREW housings given that picture. Can you?

The knock sensor thing was a separate issue that I probably should have put in another paragraph. I thought that maybe some people may confuse the knock sensor holes with spark plug holes, especially in other pictures where the plugs and sensors are removed.

Just a side note. I'm running the oil pump mod that is available on that sight. I have a resevoir that holds 2 cycle oil and injects it. My car is a 1990 T2 with a Haltech.
