The Supra Skybolt has flown.

The first flight went well. I copied the Xareltoo model settings and used that, which proved to be very close. 3, (fine), clicks of right aileron and some up elevator trim was all that was needed to get straight and level flight.
2 passes and I was feeling comfortable, so flew P19.
It goes up straight, but was pulling to the canopy on the down line. A bit more elevator in the mix and all good there.
I've adjusted the stab incidence now, which will eliminate the elevator trim.
More rudder was needed for stall turns and a touch more elevator throw added as well. Rolls were too quick, so aileron travel reduced. Snaps are OK, so will see how it goes from here.

For such a large plane, it uses less energy which is surprising. But in line with what Christophe Paysant-Le Roux says as well.

10 flights on it now and really looking forward to more flying and fine tuning the trimming.
