Hi I think that the reviews say one thing, over heating. Ok could be bad cowell very common.
But look at that huge walbro carb right in front of the cooling air.If I ran one of these I would try
to have air ducted in from the sides.I have had three of these, two as replacements for faulty engines, the first one tightened up and wouldn't run, it's replacement came with a noisy lumpy bearing, the second replacement was the same, very noisy and lumpy bearing. C'mon HK get your act together and sort out the dodgy bearings or ditch these engines altogether, which would be a shame as it is seems overall to be a good engine.Good engine but I had to remove the choke because of Turbulence's . On back position or high speed it did not work properly. Without the Choke it' ok! I set a 14x8. Just remove the little screw and little metal rounded piece on the carburetor. It's a bit less powerful than the .91 ASP nitro.
Problème d'arrivée d'air, sans le choke (en l'enlevant complètement via petite vis) ou avec capot moteur c'est ok! Un peu moins puissant que l'ASP .91 mais néanmoins très correct. J'en recommanderai certainement d'autres.good engine, powerful and well-functioning .... unfortunately broke the rod and are now more than four months that is not available. Dear HK for this great inconvenience I have to give a low rating does not so much for the engine but for the assistance. Spare parts are important ...Don't wast your money on this engine.The one weakness is fatal in that it has no needle bearing in the conrod big end. even running on 20 to1 oil i've had two seize on the crank pin distort out of shape break a piece out of the piston and then they have no spare rods in stock. What a shame as the beam mounts with excellent carby mount is a winner in designbut this motor in a sig 60 71 inch wing span and it says that it can fly with a lot lower speed than 17 cc , But when you get in to any trouble a bit more throttle can get you out of the sh if you know what I mean. this motor is fantastic no trouble at all touch wood. it ticks over like a clock and picks up like it got a turbo on it.I have one of these engines as well as the 38cc fourstroke. Both are Great.
The 17 I ran on the bench for about an hour in short bursts. Using 25:1 Red line in both engines.
4.8v Nicad Rx pack on the ignition.
I installed the 17 into a Katana 70 V2 Profile model.Just keeps getting better.
Very happy with it.I have one of these. Straight out of the box it needed NO carb adjustment and fired right up. I am running 110 octane racing fuel with a 40 to 1 AMSOIL mixture. This is a strong running engine.9.500 RPM 12x8 tripala propella
10.000 RPM 13x6 bipala propella.
8.800 RPM 13x8 Bipala Propella (best)

I bought -recently - this engine . It is beautiful ,powerful, runs perfect, not significant vibration& much better if one uses rubbery stuff(bicycle tyre tube) at the retaining bolts. BUT during the first slow flight consuming the second tank ,with the throttle not more than 30pcnt....I faced a sudden stop on the air ,...landed ,...disassembled the engine,...and....the conn.rod was smashed(the lower end) into small pieces,bent by hitting on the crancshaftknob,the piston was broken at the lower side. It may be my mistake but it is not justifying that type of failure.I am an aeronautical engineer and it seems to me that the lower part of the conn. rod is not strong enough to withstand the combustion loads....OR... the movement of the conn.rod along the piston pin is so extensive so that the conn.rod in many cases touches the back plate.
Any way I am willing to hear any comment from any one who has a better experience.
