I'm contemplating the following power system upgrade for an E-zipper:

10xKAN 1050's driving a Promax 4011, spining an APC 5x3 direct. P-Calc shows the system drawing 20 static amps. WIth the 5x3, I'll get a similar top end pitch speed of 76 mph, but in flight thrust almost doubles, and static thrust is up nicely also.

I've read about others using the 4011 on ducted fans on 10 cells, and I'm wondering if it will hold together pushing a smaller prop.

Any ideas?
