What size prop and how much thrust does this engine generate??
Thanks.
Also. I saw some one say they have too much oil temp . try Mobil one and "Total Seal" rings. Thge oil will be cooler and the Mobil One wont care up till 300 or more. the head temp is the key.

.5 VW no more

W-ASS , I bought a Cayuna 430. 35HP, 65#. much more thrust than the .5 VW, 30# lighter. Plus it is easier to push out of the field that it will quit over.
I'm building AN UL Flying Flea derived flying device.

Re: .5 VW no more

Yea but then you have that annoying 2 cycle sound, and what does it cost? The main point in the construction of a half vw for an ultralight is cost.

If your like me, i don't want an aircraft ( of any size ) that sounds like an oversized weed eater, and i also don't make good money, so the fancy, light weight 2 cycles are out of the question.

In addition, the 4 stroke engine has better (that is less) fuel consumption.

It is not a dificult or expensive engine to build. You will need the assistance of a large machine shop to do a bit of work and you will need some some aluminum welding too. I started building one years ago. Lack of \$ put an end to it. It is possible to use a hand hack saw to cut VW heads in half and even the case. It was good exersize too.
