Which KEDA motor?

[teslahed]

I';m looking at getting some KEDA motors for a carbon flyduino quadcopter i have built. Total flying weight will be about 550grams.

I like the look of either;

KD2205/50

or the

A20-50S

The specs are almost identical but the design slightly different.

Does anyone have any information or direct experience with either (or both!) of these motors that might help me decide? Thanks!

I prefer the look of the A20 hacker style motors

I think I';m leaning in that direction - if only because they seem to be used by more people, successfully, so it';s a bit less of an unknown.
