Hi All,i have now had 10 flights on my F16 and the F16/supersport combination is just right, speed is good with verticals as high as you want,a Falcon is way over the top and would be much to heavy and short flights,i can get a good 7 min,s with Mike,s third tank with some left for a go round.A Wren 54/super bee in the tail sounds good as well as some weight can be saved as there is no exhaust duct,i tried knife edge at the week end and was surprised at how well the nose holds up with no tendancy to drop just go,es on for ever regards Keith
