Definitiely not worth that price. Hopefully you don't want to put that in something big. That 2720kv will heat up quite hot on anything like a Emaxx or Revo sized r/c.
I plan using this on my 1/12 crt.5 on 3s and maybe 4s ... it is the motor I can get fastest here in canada ... a feigao 9L would cost me about the same price shipped to me as this clone motor...
