First attempt

Evan came around today to check out the engine and possibly do some fast taxi’s. He was quite happy with the engine, so had a look at the wind and decided to try a few taxis !!!!!! EXCITING !!!!!


After a few minutes taxiing along the main runway we got to a shorter one, facing into the light southerly. The video quality is not so good, but it gives you a nice impression of how things went today ๐Ÿ™‚

Coming back after first fast taxi:


Nice sound, bad video:


Also have a look at this video, taken with myย new camera from under the fuselage. I got the camera for my birthday 5 days ago :-). It shows the first taxi:


Here he is turning into the runway and does the first fast taxi, and back again. Have a look at the main landing gear during this first fast taxi. You can see the plane going up a bit (wheels dropping down).

The first fast taxi goes quite well, during the second one (not on this video) he (Evan) basically gives up, something wrong with the engine.ย I know that the mixture control is not doing anything, so we suspect that the mixture is rich all the time. So rich that one of the cylinders gets to “wet”. We checked the spark plugs to confirm that.

So I have a bit of homework to do; adjust the mixture control valve, by extending the mixture needle. From what I remember, it has some thread, so just a matter of unscrewing a bit, until it touches the valve seat when in the lean position.ย We suspect that the engine will run a lot nicer and possibly faster after this has been fixed.

During the first run the engine went up to 1600rpm, which is what the propeller is designed for, so that’s great!
Later during the second taxi I suspect that the prop only went to 1500rpm, which is what I saw last week. So everything is consistent.

Just need to adjust that carburetor and things will be fine !!!!!! (I hope, because you never know whats next with planes, but getting very close now !!!!!!!! ๐Ÿ™‚ ๐Ÿ™‚ ๐Ÿ™‚
