What are the chances of a MazdaSpeed version coming out within the next year with all that has happened in the last couple of months?

Side question: How difficult will it be to get a hold of a renesis engine within the next couple of months and how much do you think it will cost? The reason is that I will be building an airplane and want the reliability of a rotary for my powerplant.

dont hold your breath

it may be a couple years

this is a joke post mike.. build a plane?!

Umm... its a joke because someone wants to use a Rotary as an engine for a kitplane? Are you really that clueless?

It's not unusual or unheard of for production engines to be used in small planes; in fact Subaru engines are commonly used in this same market. The demands that an airplane will put on an engine are totally different than those of a car, and as such the rotary is a very good choice for powering a small plane.

However, I would say that the renesis rotary will be prohibitively expensive for this market for at least 12-18 months until the cars/engines are in heavier rotation.

i know it there are alot of variables but i would think a 20b 3rotor would be a better choice for a small plane. if you want to stick with a 2 rotor it should be fairly easy to find a old style 13b. renesis engines will be hard to come by for some time.

Kitplanes are known as "homo-built" planes, (not homebuilt).

Some are cool and serve a purpose, but it's a lot better to just buy a real one.

Not a joke, I am building an airplane with my dad. We are going to be using ducted fan technology. It is a blended wing with a canard up front. My old doctor in Storm Lake, Ia built one 3 years ago and ours is going to be similar, only his is a pusher prop and not ducted fan.

Also, rotaries are great in airplanes and kit helicopters because of the power to weight ratio in addition to the reliability.

That's great...I and I wish you the best of luck.

Just do a lot of research, more than you can remember, just so you realize what you are getting into, and if it is the right thing to choose.

Rotaries are ok in Aviation, I'm not sure I would call them great. I would probably rather have a Suburu engine if I was to build a homebuilt craft.

Who knows, Omahawk...I might be moving out to Omaha when I am finished in a month with my A+P(Airframe and Powerplant) program...and I might like to see what you are working on? Ya, never know...

omahawk

That would be great.

They've been using rotary engines for years in aviation. They like it because it's a low weight, high power and believe it or not high reliability engine... check here:

For a ducted fan application, a VW motor would be a better choice.

Hey, hey now!!! Don't be callin' the plane builder names like that!!:D

Tronics

You want better power/weight? Turbine is the way to go.

Elevation8

Yeah if you have $50,000 for the engine alone and thats what the lowest Walthers goes for. Everything up becomes very expensive.

It's very easy to make a million dollars in Aviation. Just start with $9 million first.

From what I read TRONICS, not necessarily. The rotary uses cheap gas and provides most o fthe benefits of the turbine for a lot less money.
