If my post hurt someone, i say sorry to them now. I only told the truth. How would you feel, if you tested four engines and four got the same problem? This is a serious problem. I just want to let the manufacturer know, they should improve their quality control in the future.
There is nothing wrong with Kingtech engines. We test every one of them before shipping to our customers and other than some parameter tuning, we have yet to come across a Kingtech that did not perform perfectly out of the box.
If you wish, ship these engines to us that you are having issues with and we will be happy to look them over for you.
Are you using the Flightworks fuel pump or the black pump from Kingtech?
