I bought a second hand airframe with a Jetcat P20sx, didnt like the airframe, so opted for the Sebart Mini Avanti, this was after buying the new mini Xcalibre, third time lucky! I didn't crash any of these just weren't my cup of tea, I taught myself to fly turbines so maybe that was it, they do take a bit to get used to.
The mini Avanti is by far a much nicer Airframe, lighter and much slower on landing it is easier to land than some of my prop planes, some folk say the p20sx is too small and there aren't many airframes around that suit it but I like it, its small cheap to run as it burns through 500ml per flight as opposed to multiple Litres worth.
In saying that I have just bought a second Jet a DeHaviland Vampire with an 80 size turbine in it, so all I can say is you wont be able to stop at one, they will make you poor, but you will have the biggest smile on your face after your first flight.
