Sky Flight Hobby P40E Warhawk 2000mm PNP (green) the WORLD’S largest & most scale Foam P40

⚠ Upgrades compared with Lanxiang’s 10 years old P40:
ESC, motor and servos are upgraded.
Metal landing gear, changed the materials of the landing gear, to make it more tough!

Wingspan 2000mm, Length 1711mm, weight without LiPo 4000gr (with Admiral 5000 50C : 4700gr )
Wing area : 67.25 d㎡
Wing load : 59.47 g/d㎡
Propeller diameter : 18×8in
Thrust : ≥5600g
ESC : Hobbywing 60A
7×Digital metal 17g servo
Brushless motor : 5060 290KV

CG 36mm in front of the trailing edge of « gear’s cover » plane upside down gear up ! BUT it’s easier to measure 115mm from leading edge of the wing just next to the gear : Admiral 5000mAh 50C (705gr) or CNHL 4000mAh 70C (690gr) all the way forward (we don’t have the choice for the LiPo placement…)

My rates Low/Mid/High AFTER MAIDEN:
Ailerons : 80% (25mm) / 90% (28mm) / 100% (31mm)
Elevator : 50% (20mm) / 60% (25mm) / 80% (32mm)
Rudder : 30% (21mm) / 70% (45mm) / 100% (60mm)
Flaps : No flaps for takeoff but 20 degrees (30mm) for windy landing flaps and 45 degrees (65mm) for no wind landing flaps, with 5mm down elevator compensation (10%)
Throttle to right 10mm rudder mix (20%)

⚠ Add a few clicks of throttle trim before the takeoff to keep the plane straight on the runway axis after touchdown !

Build tips:
Reinforce fuselage junction with carbon rods 4mm diameter because glue isn’t enough (renfort avec 2 joncs carbone 4mm entre les deux parties du fuselage)
I added 4 magnets to be sure the huge cockpit won’t fly away (j’ai ajouté 4 aimants pour sécurisé le cockpit)

Flights with LiPo & timings :
1st CG 115mm from leading edge, gear up, upside down // Admiral 5000 : 4m38 (4m29 motor) 3.85v
2nd : CNHL 4000 70C : 4m40 (4m21 motor) : 3.86v
3rd (around 6070% throttle) : Admiral 5000 : 5m05 (4m50 motor) : 3.86v
