F18 Blue Angle reach 120km/h airspeed!

My Align Team.







Align F16 400, modified with twin vertical fin.
Wt . of plane 350g + 210g (3s lipo)
450T/1800kv/2200mAh 18c/35A ESC
It reaches top speed of 107km/h at 280W with 3s.




Then, 4s 18c lipo of wt. : 280g
At 4s it pulls 380W, reaches my record breaking of 124 km/h.
With 6x5.8, motor is slight warm. Unlimited vertical.
With 7x7 propeller, the speed is not impressive and the motor is hot.

Another test flight with 3s/3000kv 450TH/5x5 APC, pulls >38A and speed ~ 110km/h. Acceleration is not impressive. Cannot performed vertical> 4s.

3s/3000kv/4.75x 4.75, pulls 32A, though calculated pitch speed>150km/h, but the thrust cannot overcome the drag to produce enough acceleration to reach the desired pitch speed. Unfortunately, I found my propeller mount slipping against the shaft and may result in the poor performance.
