That motor may be cheap but I doubt you would ever actually see it after all the stuff I have heard and read about Hobbyking, and if something goes wrong with it you can forget getting a replacement or any kind of customer service...

Scorpion may be expensive but you get the best, and their equivalent motor, going by weight, is way more than $300...

its $1000!

If I had the money I would buy that to go in LS4, just to see what would happen
