Finally got my Natrix flying after 5 weeks of building & installing. What a VERY nice plane! Good job Paritech!
B300F turbine, Powerbox Mercury SRS with two Futaba R7006SB receivers, 6,2 liters fuel plus large CAT,1,5 liters smoke oil plus large CAT on that too. Dry weight a bit high 19kg because of the large turbine and quite large LiPo's, still flies very light even full of fuel and smoke oil. Haven't tried full throttle level flight yet, but climbs nicely with 30+kg's of thrust.
Flaps are very effective, landings are easy. Knife edge slight coupling to bottom side, very little in fact, no aileron compensation needed. Don't know exact CG, 380-390mm range I suspect. Very neutral behavior, minimal down elevator needed in inverted flight. Had six flights with gyro turned OFF, next time out setting that...maybe some video too...
