Right off the bat the jet is a great flyer and I loved mine. The air presence for a T33 is outstanding and it rolls like it has a stick up it's butt. The build...a royal pain in the ass. For a supposedly engineered jet you will spend a lot of time making things work. Rudder servo, stab installation, tank fitment, operating canopy all required too many brain cells for a jet that has been on the market that long.
