Habe das Einlaufen heute abgeschlossen. Motor startet gut und ohne Probleme, er nimmt das Gas schn und kontinuierlich an. Einzig die Vibrationen sind etwas hoch. Aber sonst ein guter Kauf
It seems to be a good engine. I have finished today the break-in. It is easy to start and also to restart. Only the vibrations are a little bit high. It works continuosely from low to full throttle-position.

Starker Motor dreht eine 17x8 Luftschraube mit 7800 U/min. 6 kg Schub leider sehr starke vibrationen wahrscheinlich ist die Kurbelwelle nicht gerade. Habe den Motor nur gekauft wegen den kleinen Abmassen.

I purchased the engine January 2014 and installed it in my Sukhoi. After around 20 flights, the engine lost completely the compression. I can turn the propeller without any resistance. To start only with e-starter. Would like to know if somebody had also this bad experience and what could be the reason.

Nice little motor. found bottom end mixture way to rich on start up had to go in 1.5 turns.
after that ran it for 20 minutes on the ground with varying revs then let it cool down,
had to re tighten the exhaust after the cool down, but other than that and the minor tune
it runs sweet with 16 x 8 prop. only pulls 8200 rpm with this prop but its plenty and runs well. mine came with the Hi voltage ignition module that will handle 8.4v so with a life battery no bec required. all in all not a bad little motor. no issues with the motor in the air ether with the first days flying so thats a good sign.

Here's a couple of links showing the ARF from HK and the Engine during the break-in period. You can see a lot of other accessories from Hobby King:

Nach dem Einlaufen ein schner Motor, leicht zu starten, sehr kraftvoll.
Kann ich nur empfehlen fr Modelle 6 - 8 kg.

A very good engine, however in the box a spring comes to put inside the spark plug cap. A sketch shows how to instal it. But during the flight the cap becomes loose, due to the spring, and the current interferes in the receiver and the airplane remain without control. Therefore I recommend not instal the spring. May be someone can give me another advice.
