I can't imagine very much more questionable than a flying machine built around two-stroke motorcycle engines. He probably realizes this, though, and has no illusions about its suitability to 'real world' use.


Actually, microlights of the last decade were built around 2 stroke engines originally designed for snow-mobile use.

My main concern is that an engine failure in that design is an instant crash from whatever height you happen to be at.


Rotax also makes a four stroke (the 912).

I've flown an ultralight once and hung around an airfield for a while it's an amazing world. The aircraft that class as 'ultralights' these days can be pretty amazing:

Retractable landing gear on an ultralight? Check ;)

I decided against taking lessons because it felt like I could very easily get addicted to this.

edit: and wikipedia lists another 4 stroke, the 914


A good friend of mine owns a Rotax 503 powered Flash 2 Alpha flexwing.

I've been flying quite a few times, once after doing its 50 hour overhaul. Really interesting and simple engines.

Pretty cool way of spending time!


You should visit an ultra light club, two strokes are pretty common.


I'm well aware of ultralights. Don't you think it's somewhat different strapping a motor to something which already glides safely without power?
