Hello J600 owners,

I installed the J600R in the Skymaster Gripen with the engine inverted inorder to have easy access to the glow plug. I have found out that mounting the engine inverted with glow plug at 5-7 O'Clock positions will cause "Hung Start". I managed to start the engine in this position with the assistance of an air blower. Once started, engine operated normally and not affected by the mounting position.

To avoid the "Hung Start", please rotate the engine so that the glow plug is out of the mentioned positions. We are looking into the problem and will fix this flaw asap.

Thank you.
