What you have to remember is that this little motor is just a regular schnerl ported airplane engine with a bronze connecting rod.Its very important that you yous the proper oil mix.I yous Klotz bean oil which is a mixture of castor and synthetic oil.So far it seems to perform very good.You have to use more oil mix because of no roller bearings on connecting rod.Got it the other week,sat around and looked at it while sitting and and watching TV.So i said to my self.Self we got to get this thing mounted and fired up.Mounted it on the same mounting i used for my RCGF 15.Boy you ought see this mount,it looks like something out of NASA.Well anyway it works.The mount that is.The engine is a little stuburn but it finally started and i ran it up to 3600 RPMs as fac. recommends for about 2 hours.Steady runs to help seat the ring to the sleeve wall.Unbolted muffler looked into the port and i could see myself in it.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.
