things i didnt like about the sonex ( i could be reading these wrong )
MTOW = 1100pnd = 500kg / small fuel tank at 16 usg = 60lt and with a jab 3300 thats less than 3 hrs but you do get another 20kg on the MTOW
im mainly putting this in here so i can be enlightened as to whether or not im reading this correctly
Ultralights with a plane like the vampire im not surprised you like the sonex
they both look very cool;)
I have just done a trip from Kilcoy to Ceduna and return in 27 hours flying time. Standard taildragger Sonex with a Jabiru 220 engine. I was originally on my way to Perth, but ran out of oil at Ceduna. I travelled light with only one litre spare thinking that because there was a BP Aviation refueller at Ceduna, they would have aircraft oil. WRONGGGG! Long story, which I will write about in the RAA Magazine sometime.
As for the litttle Sonex - it went great, considering that I picked about the worst possible heat wave to attempt the trip. 40 degrees on the ground everywhere I went. TAS was about 95 to 100 knots at a rock-steady 15 litres per hour in some terrible turbulence. Part of the reason for the TAS being a bit less than advertised was because I did not want to flog the engine in the heat, and part was probably due to the oversize wheels and tyres I fitted. 8 inch Asuza wheels running 480-400 x 8 boat trailer tyres. Of course the wheel spats had to go.
As pretty as it looks, I am not sure that the V tail would handle the turbulence and crosswinds encountered nearly as well as the straight tail did. Never a bad moment despite some impressive gusts and turbulence on several takeoffs and landings. Maybe the V tail would be OK in a nosewheel configuration, but then it wouldn't look as pretty and would lose a few knots over the taildragger.
