RE: SHORT FEILD JET
Boomerang Sprint is the shortest landing of all the Boomers, I had an Elan and have flown the XL at our grass site and the Sprint lands very short, the Flacon will float on if you don't modify the flaps to get 90deg movement and crow braking on the ailerons, then you can land it slower, but the Sprint still lands shorter, and its an easy flying first jet in its standard form, the Falcon needs work to get it ready and suitable for a turbine install.
My Sprint has a JetsMunt 90 in it, lots of thrust to play with, about the same as the Kingtech if I remember correctly.
