I have a Kingtech K100G with (176 mins) 2.56 hours, she has been In a crash but was rebuild this past January.
She was repair by KingTech USA, the following was items were replaced;
Front Cover RPM board Starter assembly Turbine housing
It was cleaned, rebalance, and test run.
It always starts and runs great on diesel with KingTech oil 5% mix, it’s complete, I’m including the Xicoy Telemetry (Jeti) and MAP pump mount, selling it because I have no plane to put it in, and could used the $ for other projects.
