A.I. Pietsukh’s PAI-67

The A.I. Pietsukh’s PAI-67 is interesting and unusual configuration.

If you the look at the drawings (assuming they are accurate) the fore wing appears have less angle of incidence than both the main wing and rear horizontal stabilizer. Both of which appear to have the same angle of incidence. This goes against my understanding that a stable tandem wig configuration where the fore wing should be the higher loaded wing.

The rear horizontal stabilizer is set much lower than most ram wing and lippisch reverse delta wigs...but the elevator is huge. I wonder whether the horizontal stability was controlled by the trim of front water prop drive and/or hydrofoil.

The main aft wing planform also very interesting. It could almost be considered a Double Delta Wing Bixel with anhedral.
