I have 3 of these engines flying an am impressed with how nicely finished they are. Mine installed with no problems and I went ahead and set the needles at a turn and a half each for initial start. Cranked with electric starter to get fuel to engine and they fired right up. Ran most of a tank thru with a 30:1 mixture then tuned the needles again for smooth idle and max RPM. Have many flights of one and several on the others all without any complaints. I'm using an 18-6 wood prop getting around 8400 rpm with steady running Still keeping 30:1 mixture (oil for air cooled engines only, not outboard oil). RPM should increase in time as it wears in more, but plenty of power as is. I really like these engines and have purchased two more for pending aircraft projects.

I have several of these engines now. All start and run superbly producing lots of power. Machine work is awesome compared to others. Ran in initially with one tank of fuel which was enough to get it to accelerate/idle down smoothly, then rest of break-in is done in the air. Using 18-8 and 18-10 Turnigy wood props for the most part. Couldn't be happier with these engines. Only concern is HK doesn't seem to carry any parts (haven't needed any so far). Hope that gets resolved shortly.

Very beautiful looking engine with its "chrome" look. I plant this on my Great Planes Giant Supersportster. Tried tuning and running last night at my workshop, very much louder than my RCG15 and 20cc engines.

Packs loads of power churning 18x8 Master Airscrew propeller. I did not take the RPM reading from the meter but all tuned by ears (i have plenty of gasser experiences).

So based on the recommended setting as per manual, idling was between 1550 to 1650 and the max RPM was above 8500. On the first run, sudden full throttle from idle and vice versa would cause engine to stall. But after 600cc of petrol, no more such issue.

I read 'poor' reviews about this engine that the mid-range is hard to tune, but I lucky as I do not experience that with this piece.

This is a big engine, so it is forgiving. You need to treat it gentle on the tuning unlike smaller counterparts. After running another 600cc of petrol, I will fly to run it in further.

I think this is the smoothest running gas engine I've ever run. Quick transition and responsive. The added bonus is the great machine work . Very impressed with this engine. Installed on a 70" Sukhoi.
