	Claudio Uccheddu built 309 airliner -takeoff and fly pass (2 Mb wmv format) - Feb 2009
	On board video -landing (4.9 Mb wmv format) -3rd June 2007 Two circuits and then the landing. Points of interest from my own perspective- I thought the landing was particularly steady. One reasonably rectangular circuit of the field, followed by a fairly steady downwind leg, smooth turn to finals and smooth landing.I expected both the take-off and landing footage to be so poor it would be totally unusable. I expected it to shake violently because of the bumps in the grass runway. The smooth take-off and landing took me by surprise. Of course what this is really saying is that the U/C design is correct and the runway well maintained. A tarmac take off video could be done nicely really nicely. The engines are very flexible in their mounting to the pylon. By flexible, I mean if you hold them in your hand they will easily rotate on their mounts. Upon impact they part company with the wing and little if any damage occurs. I had been confident in their steady behaviour in flight, but it was particularly pleasing to see them rock solid in flight. The maximum movement of the ailerons required looks as though it is small. You can see the top of the aileron a second before landing with larger input control close to the ground. The wing flexes and it will be interesting to see what happens when a serious load is applied. The speed of the model is not accurate. When video is uploaded into the editing program, regardless of the quality specified the frame rate tends to speed up the video.
	On board video -in flight & stall (4.8 Mb wmv format) -3rd June 2007 The airliner is allowed to stall. The rushing wind sound disappears as the model reaches the top of the climb and only the engines can be heard.
	On board video -take-off (4.6 Mb wmv format) -3rd June 2007 A strong & fast take-off climbing to a reasonable height in the circuit. It is only the second test flight and confirming trims settings was required. Video ends on downward leg after fast first circuit.
	309 RC airliner maiden flight video (4.5 Mb wmv format) -28th April 2007 If you are using Windows media player -the file buffers first before displaying. A successful flight despite two issues which are obvious in the video. One fan is out of balance (the grating sound) and the model it is out of trim. Upon take-off the video shows clearly the 309 banking, but to easily recover. Both were set-up errors. The model completed several circuits at attitude and speed until some sort of trim was restored. Handled well on landing. The C of G was very close. Rear retract units handled take-off and landing well, although there was no gear up in this flight because of the trimming issue. Not as slick through the air as the 307, but to be expected with the drag of #2 engine in the tail. A thank you to Geoff Pinkerton.
	Rear main U/C retraction on the 309 (0.5 Mb wmv format) -28th April 2007 A go-slow servo unit has not been used here. The Robart retract units require a soild and positive lock-down.
