Not sure where 7 hours comes from, the one I fly with 2 bodies is only capable of carrying one hour of fuel!!! With just me in it around 4 hours.
I do recall the total loss of a Sywell based CT recently by an airline captain who thought it had a better range than it actually has.............
Not wanting to start a debate.
The CT is a nice aircraft put for £40 odd thousand, it is a lot of money for a a "limited" aircraft. That sort of money gets you a group A aircraft with the same performance.
For cheap fun ML flying, AX2000, AX3, Thruster etc. are the fun machines, cheap and reliable. Or weight shift which comes even cheaper in a lot of cases!
Another point worth noting is that with the NPPL, your microlight experiance is now accepted in converting to a group A. You only have to do sufficient training to pass the skills test to go from NPPL ML to NPPL SEP and pass the JAR exams.
