4-Strokes .vs. 2-Strokes, was new things available in Japan

[Bjorn Lehnardt]

I'm thinking a bit bigger than the MVVS for both the engine and airframe.
I think 40cc is the minimum viable size for a competitive gasoline engine.
The smaller ones are interesting, just not suitable for my goals.

I hoping to try it soon.  In 5 years there should be some very
interesting things going on.

I've finished 3 hours or so of running my MVVS 1.60 on
a test stand.

I'm going to put it on an Ultrasport 1000 for further
tuning in the air.

Then I hope to build a small, light, patternish plane
for it.  (This could take a while.)

I've got a pipe from Pé Rievers.  Haven't tried it yet.
I'm optimistic that it will help quiet it down.
