.05 brushless comparable to a 400 brushless

O.S. .05 Brushless Motor 3805-1200
Is this engine comparable to a 400 park flyer?

I wanted to use a dif. motor other than the following......

Great Planes Rimfire 400 28-30-950 Outrunner

It appears to be larger and heavier.

Great Planes ElectriFly SPAD XIII WWI ARF 34" Calls for the 400 Rimfire outrunner....

Any help would be appreciated...

RE: .05 brushless comparable to a 400 brushless
Yes, it is a bit heavier (76g versus 58g) but if the little bit of extra weight doesn't affect the CG (on a bipe you might need extra weight in the nose!) it should be fine. The higher Kv (1200 versus 950) might mean you'd have to use a slightly smaller prop than the 10 x 3.5 recommended.. but maybe not [O.S. specs say 9x6 (3s?)-11x7 (2s?)]

This might be a better choice:
