Hello folks,

One of my customers is having trouble with his brand new DF60A running about 5 hours now. He is a bit far away from me, but he send me some videos:



As you can see the engine significant drop the rpms when running at higher rpms for a short time, and then after a few seconds it also stops completely. After it stops itself, it is somehow difficult to start again immedietely.

There are no engine faults appearing on the instruments and the engine runs perfect at slow speed.

Does someone have any idea what the problem is?
