Not unusual at all. The two sport jets I have now go off in the low to mid 40's with full fuel. Three other semi-scale airplanes I had ranged from 65 to 75 at takeoff. Probably one of the reasons for the turbine waiver flight test is to demonstrate you can manage your energy with a highly loaded airplane. The sport airplanes are probably all towards the low end (say 30-45) while many of the scale birds reach some pretty high loadings.
