Well, today our next gyro made its initial patterns over Twist nest.
This is a tandem with Simonini Victor II Plus 102 hp 2-stroker.
I had some minor problems during first engine runs but we solved them.
The most unpleasant was that at engine rpm below 3200-3300 it thrown a lot of fuel out from carbs. I have close to zero experience with 2-strokers and cannot imagine that this may be caused by air filters but when I replaced it's original double filter with two singles the problem disappeared.
Engine runs well though I feel it needs slightly other prop for it - will see.
Very low vibrations and noise. I'd said it sounds even less noisy than Rotax-912 - surprisingly.
On the other hand there is still too little information from other owners about these engines habits so it won't fly any cross-countries before we get enough experience with it.
This gyro is based on the first stainless airframe I built so it still has some things I changed on the later airframes. I have one more such Simon engine on shelf and a new airframe for it which should fly early this summer.
Cheers,
