Help! Master Series P51, prop size

#1
I did a maiden flight on the MS P51 and it flew like it was way under powered. I used a C motor with a 10x4.5 prop that they sent with motor.
What size prop are you guys using?
Thinking of trying a 11x4.7SF

new radial FT 2218-1180 V1 "C" pack
TATTU 2300 45C 4S
FT 35A ESC

I have been flying the FT 3D with the same motor, on 3S 2200mAh, 10x4.5 prop and it flies great.

It flew but would barely climb, can't do a loop.
Using CG 3" in front of the scoop (the part that touches the fuselage, not the part that would touch the ground).
 
#7
no, it was forward. I flew it twice for about 7 minutes. Broke the prop so not on right now.

Just curious what prop everyone is using.

Wierd. On my master mustang I fly the FT Radial with a 9x4.5 on a 4S 2200, and I've easily got enough power to do loops at half throttle. That's very strange that your's was so underpowered.

i am at a loss, weight is only 20g more than the plans say.

...wait, you said 9x4.5, did you mean 10x4.5

I maidened mine on 4S 2200mAh, 11x5 prop, 2628 1200kv Turnigy motor. Underpowered, level flight at 75% throttle, burned the motor after 5 minutes :(
But mine is about 1300g AUW... Very heavy foamboard
I am currently taking suggestions for a big enough motor :)
