Rotaries
Any rotary engined locosts out there?
I got thinking about it the other day, small, light and powerful, exactly what you need in a locost! 
RX7's are rotary powered, as I believe are the earlier RXs. Anyone think of other rotaries? I think Toyota may have made one once apon a time.
Are there any issues involved with rotary engines that don't apply to piston engines, i.e. would I be asking for more hassle by going that route?

Graham,
Think it would certainly make an interesting talking point.
Have a look at:
http://www.dmack.net/mazda/information.html
It's an aircraft based site, but quite informative.
Also
http://www.rx7-uk.co.uk/
Nice animation showing how it works!!
Also and RX7 enthusiast's site:
http://www.delphinus.demon.co.uk/other/wankel.html
I don't think it should give you any major headaches. After all, it's still only an engine. You'll need mountings for engine and box made, but
we're all doing that, aren't we. As for rear end, is it IRS or a live axle (or a transaxle).
Certainly different.
Good luck
ATB

allways said if i aint gone BEC then i would have gone Rotory, drove a grass car with one in, very nice, only difference little or no engine braking,
there light and powerfull, good luck, go for it.
if you do though IMO only think Mazda, seen them for sale re~built well under £1k, try motoring news or a add on Findit.co.uk

An engine that can rev easily to 13 000rpm, go for it!

Rotary engines offer immense power for their size/weight, coupled with a low centre of gravity.
Minus points are that they are VERY difficult to silence to acceptable levels, and are VERY thirsty on juice.
I have seen Westys and Strikers with these motors in, so no problem insurmountable.
HTH Stu.
Dont just build it.....make it!

I gave up on the locost idea and bought a Mazda RX3 last month with an RV8 in it. it used to run a 2000cc rotary engine. Mazda bought the Wankel
design off from Audi after NSU (the only other rotary producers you care to think about, and a sub company of Audi at the time) went bust on warranty
claims. My advice, (if you persist in going for a rotary engine), dont take an old one circa 70's or even early 80's. Keep it limited to RX7's, as
they are the only ones common enough to find parts for, and reliable enough to not have to look for parts every 37.4 miles.

Check out American Locost sites- rotaries seem very popular amongst that locost community. I ahve found plenty of build pages (USA) detailing rotary
powered locost builds.
If it isn't low-cost it isn't locost!

the sealing vanes in the rotor tend to carbon up and not seal the engine very well, usually caused by old people driving the car sensibly. Rev the
engine harder for a while and it should clear. Got that information from someone who used to work for mazda.
