Bought this engine whilst at a good price and wanted a twin for a new model. Started to run it in as in the instructions and OK for about 35minutes. The engine started well on the factory settings and looked and sounded fine. Looks well finished. With 22x10 prop the initial impression was very pleasing. Unfortunately after about 45mins of run time a loud rattle appeared from the crank case which quickly developed. On stopping the engine it appears to have real problems - Prop binds, engine knocks, looks like there is an issue with the con rods or big end bearings. With mufflers off and plugs out it turns over OK but once plugs back in and under load it sounds dreadful. Now need to send it back to Hobbyking so not as good a deal as I thought as this is a heavy item. Not sure if I want to chance another NGH GTT70 or maybe I am just unlucky.

Mein Motor hat jetzt 2L 1:35 mit mineralischem Öl durch.Eine 22x12 wird locker mit 5400U/min gedreht und das Standgas liegt bei 2200U/min. Eine Feinabstimmung folgt noch. Der Motor sprang erst nicht gut an. Die Luftschraube muss auf 12 Uhr stehen, dann kraftvoll durchziehen. Die Schalldämpfer sind nur als Krümmeransatz zu verwenden, deshalb einen Stern abzug.

Very nice engine High Performance easy to start, uses a power distribution with voltage regulator 6v, Prime the engine than handstart and results are very good. Advice this engine if you want a 70CC like boxer!
