Same here Ali, i own 3 of them my first one a 2010 model K80E had only 6 hours on it all flawless the reason of low hours being due to an accident that kept me away from flying.
This year i started flying again and flown the engine 3 times and suddenly shut down in flight. On the 10th of April i emailed Barry/vera and got a reply to send it direct to factory.
Around the 20th i believe the factory got the engine....then silence....i thought hey it must have been a big damage not to have a response from the factory !! Then 5th of May i got an email from Vera to give my address as the engine is ready to be shipped!!! 10 days later i got the engine with new ecu wires and i believe a new outer case and god knows what else.!! All these cost me 30 euro shipping from Cyprus to Taiwan...need to say any more for this excellent service?
