Thanks for the comments. I'm am satisfied with the engine. We talk about service support but in my 56 years of flying (control line and the RC for the last 30) I've only sent an engine in for service one time. I sent a DA 50 in after a bad crash.

Biggest issue for engines from Europe is in the US we have lots of exhaust options for our China based motors, not for European: HOWEVER, we can make our own.

The Valach is the best engine from design standpoint I have ever owned. It is on par with the best OS and Saito 4 stroke glow engines.

I would buy a 2nd one but, as I stated earlier, is to almost too big for the plane I'm going to use it on. But I love that 32" prop and the sound.

I'll post info when I get it flying in a month or two.

I first had Italian engines when I bought (my dad and I) Rossi 60's in 1960. These were 10cc glow engines and we ran 60% nitro in control line navy carrier. Ran about 18000 RPM; top speed was about 140 mph.

The Valach looks every bit as promising for performance in high torque, scale.

Hi
I own an vm 210 and have bin trying to get a new part for my engine but have had no luck so far, i am
actually considering of selling it as a spare part engine.
The engine have bin started, but has never been in the air.
I can not say anything about the quality of the engine since it has only run a few minutes, but the service and support is just absolutely miserable.
Such as the situation is now considering support and service, I can not recommend this engine to anyone unless you have a deep pocket an can by a new engine if you should need a new part.

Karl, great flight. Good landing for a short, rough turf runway.

There were two Valach 120's at the Mid-Atlantic Dawn Patrol, in Virginia Beach this past week: one in a 1/3rd scale sopwith pup and the other in a 40% Paolo Severin Eindecker 1. Both could fly very scale like or like an aerobat when the engine was opened up.

What size prop are you using and what hi-low rpms are you getting? Oil and oil/gas mix?

The prop is a Biela 28x12. The motor is in the break in period, and I use 4% Valovoline Full Synth 2 stroke. I am to put in telemetry and RPM sensor so I can read the RPM in the air. That will be when I reduse the oil mix ti 3% after 5-6 more flights. Until then I run with high idle and low full speed.

I have the first generation Valach 120 on my RC pilot Edge 540. I love the motor, but after only 70 flights, i had to send it to Czech Republic for bearing replacement. It took a month to pass customs. I should have the motor by end of the month or mid November.

William, when did you buy the motor. Mine is probably same lot.

Karl, the two engines were running 32 X 12 props, cut down to 30 X 12; Dr. Vogelsang said the engine needs over 4 hours of run time before going to the larger prop. Looks like you knew that.
