Thanks swiftprop, grostek, AndyCAP
Please keep the news coming till you are free to fly where you want
OK AndyCAP, will give some feedback as to how things progress.
Below are my tracks for the first 7 flights after the initial test flights, you can see I'm not too ambitious yet. (before anyone wonders what the non highlited tracks are, they are my TBird tracks)
I'm roughly following the FAA AC 90-89A "Amateur-Built aircraft and ultralight flight testing handbook".
The last 2 flights was all about the engine... is da fan gonna stay switched on...
After each flight I re-torque the prop, and check every detail in the engine bay. The bolts on the prop did'nt need any re-tourquing (?) the last time so I will check every 2 flghts from now.
Now that I'm more convinced all is reasonably OK in the engine bay I started to look at some performance figures. First (pretty rough) check was a climb out from take off. Average speed with flap disengaged after 200 ft was around 53MPH, profile below shows I climbed around 850ft in a minute.
This weekend I will get into more checks, like airspeed indicator accuracy, cruise speed etc....
