I'm trying to build a very light P-51...but one that has decent speed (40mph-50mph range). My build will be about 490 grams AUW

Here's the plane:

Here's the motor I want to put on it

Does anyone have this motor...and can you share experience- can it manage 6x4 or 7x4 and estimate thrust...

from the specs, I see it's

Model: D2822/14
Weight: 38g
Dimensions: 22 x 28
Voltage: 7.2v~11.1v 2s~3s Lipoly
Kv: 1450rpm/v
Shaft: 3.17mm Diameter
Max Watts: 160W
Suggested Propeller: 8x6(2s) 7x4.5(3s)


max watts is 160w,...so I'm thinking it will work fine...and should get me almost 1:1.5 power ratio...but I would rather hear it from rcg...we all know how HK power ratings are

my next thought would be this motor if the one above is too small on power...

but then I would have to get a bigger esc, bigger Lipo...etc.


thoughts? comments....welcomed.

thanks.
