Having put on a few more flights this last weekend on my turbine converted Sabre a few comments:
The model was converted from a DF to PST 600R power using the BVM conversion kit but I did not glass the stabs.
The PST 600R is a perfect match and gives excellent acceleration and vertical performance.
Take off is a doddle, 15 flap and hold half up elevator for perfect rotations. Flaps retracted on downwing leg, little trim change.
Rolls very smooth and axial, loops fine no snapping tendency at all. Inverted requires a gentle push, no problems. Four point and slow rolls v. straightforward. C of G as per plans.

For landing drop 15 flap downwind, then gear, full flap on finals, slight trim change, very smooth landings easy to accomplish, a delight to fly.
The old "crosswind conversion kit " led to some skin cracking on the upper wing surface above the main gear, now removed.
Duct and fuselage cold when engine running but best to remove canopy and bypass hatch during engine cooldown as a lot of heat is released. Probably the nicest scale jet I have ever flown.
