I fly a bandit ARF with a 23lb turbine and it is quicker than my flash was. I guess the thicker wing section on the flash helps slow it down but it still had good pace with a P120 in it. It also meant it was pretty versatile in aerobatics. They are really tough aeroplanes - I remeber not just me but lots of guys doing some really fast snaps and spins - then rebuilding the speed and flying on out.
As it was my first jet and I was flying from grass, I played with slowing it right up on landings and it never bit me. I did have some problems with it pulling in Knife edge but some playing with the CG helped to eliminate it.
