From the race quad industry comes an affordable yet powerful option for your smaller R/C flying contraptions. We call this one the "big block" for the 1404 sized motors. She packs a little more punch. 

We have designed special folding prop spinners for these where the motor fits inside the spinner. This makes for some very nice packaging.
