Good but not multiwii compatible

Overall Rating:

Pros:They seem like pretty good ESCs and are programmable for three different speed ranges. Useful if ou want to use a High KV motor on a larger framed vehicle.

Cons:The default (shipped) speed setting is set to the lowest. You will probably want to reprogram them to go full speed. You can find a spec sheet with how to do that by searching online.

Other Thoughts:If you are buying them to build a quadcopter using Multiwii software, they won't work without a patch. Multiwii updates the ESCs at 490Hz and is not configurable (without a patch). These only support referesh rates up to about 430 or so.

Bottomline:At less than $10 a piece for a four these are definitely worth it if you can manage the extra programming involved to make them work.
