I'm thinking this must be version 2 of this engine. The crankcase relief valves are now plumbed to the intake. Except for the front bearing nipple. With a "Y" connector I simply tapped this to one existing tube running to the intake. Starts easy. Runs stable and smooth transition. Will idle at 1700-1800 forever. Will be installed on a ESM 30cc Beaver. So far nothing negative I can say about this engine. I have also installed the aftermarket muffler offered on this site. Very reasonable price for a solid cut aluminum muffler, compared to the ridiculous cost of the other cheap, thin aluminum offered on this and other similar sites... I would buy another without hesitation if I needed one.I have also ordered and received this engine and I must say, it's a good piece of workmanship.I have not yet started the engine but I have great expectations,I have also ordered and received this engine and I must say, it's a good piece of workmanship.I have not yet started the engine but I have great expectations,Surprising value and performance for the $. Pulls a 1/4 scale Tigermoth with authority and nice four stroke sound through the straight pipe, no muffler needed. Arrived tuned and ready to run. Needed 1/8 leaner turn on the low end jet. Idles smoothly at low RPM. Transitions to full throttle instantly. I also run an OS FG40 four stroke gasser. The OS has more power, but for $450 less, I'm planning to order another NGH soon. Measure your cowl length though. With rear carb and a long crankcase this engine is longer than some others. I took 1 3/4" off of the engine box for the Tigermoth and reinforced the new firewall well with gussets and fiberglass.I bought this motor for a Piper Pa - 25 with 2580mm span . the motor runs very well and quiet.
The Price and the Quality of the Engine is also very goodBought a new one of these last summer. Had to go to Aus tars for a beam mount and Big Pla nes for a muffler. Apart from that, the thermal spacer (white washer was not flat and was causing an air leak in the inlet. After fixing that, it ran great. Is being fitted in a 1/3 scale SpaceWalker. A friend then sold me a slightly used one for 60 (Thats what I said) and also had the same problem. Quickly sorted, it flew last sunday in a Cap 232 72" span and was a great performer. Very clean, sounds right, and lasts 15min on a 16oz tank. Using a 20 x 8 prop at 6000rpmSo far so good. Only ran half a tank through it so far with 30:1 oil mix. 18x8 wooden prop.I have received this engine from hobbyking recently. It was in a perfect condition when it arrived. All additional components neatly packed in separate bags. I have read on some fora that people received their engines with damaged cooling fins, but not this one. Must point out that these engines where not supplied by HK.
Assembled everything and can't wait to start her up tomorrow. As soon as I have tested it I will post video's
I have the engine and it runs great. Hard to start the 1st day, but after it runs, I can re start it by hand. has anyone tried running the engine with higher Octane? I'm running regular pump gas 87 and I need to run higher for my other gas engines at the field. will 100 Octane hurt this motor at 25:1 full synthetic Oil?I put this engine on a Hangar Nine 1/4 Scale DeHavilland Tiger Moth. I have had four flights on this plane/engine. I really like the engine. It idles very well and has tons of power. I am using a 20X8 Xoar prop and there is plenty of pull. The idle is fantastic and the sound is awesome. I have not had any issues with it thus far. I did run the engine on the ground for break in using approximately 40:1 mix. I was able to start the engine by hand from the start and have been able to hand start it, although it seems to take a few more flips than I would like. I am inclined to believe that the problem is with my fuel supply setup and not the engine. I am using a two line fuel set up, one for the clunk and one for vent. The fill comes into a "T" that is between the carb and tank. I can see that I am getting some small air bubbles in the line when I am filling the tank, so it stands to reason that air could be getting sucked in to the carb, rather than the fuel. It is a fine engine that runs really well. I have nothing negative to say about this engine.
