So how does it fly?

Pretty well actually :-)

It is a very comfortable model to fly. It is VERY strong. I can compare it to the 2.5m Futura and 3.5m Viper XXL and it's a nice blend.

It has an incredibly powerful tail, not surprising given the long tail moment. The elevator will just pull the nose around even with full flaps and low airspeed very much like the big Viper although it will gently stall a little easier then the viper when doing these slow tight loops with full flap(which has a much larger wing and stab). Otherwise the elevator pulls it very nicely at speed and the nose tracks very predictably.

The rudder is very effective. I am not sure yet if I can do a KE loop but it certainly has alot of KE climbout and is a more powerful rudder than the Viper or the Futura. One turn rolling loops are no problem. KE is without aileron mix and a touch (1%) of elevator mix.

With the differential dialed in the rolls are as axial as the Futura and Viper if not more.

The model will do outside snaps and spins and winds up nicely, about like a Futura.

Slow flight is rock solid and it cruises around nicely at probably 125-150 mph. Faster flight is somewhat limited. Top end seems around 180, not Shockwave/Ultra Bandit fast but I havent really cranked on it and have nothing else in the air to compare it too. I know an official set of inlets are being designed now which will certainly help and a full bypass would probably be just the ticket.

The retracts work as expected and the e-brakes are nicely smoothed out by adding a servo delay in and out (20 for Futaba).
