This is why many of us recommed that you buy the best name-brand equipment you can afford. If you have spent the money on a decent airframe, engine/motor, servos and TX, why buy a cheap RX and risk it all for a few dollars?

Don't get me wrong, there are many quality products out there for less than you might pay for say JR, HiTec, Futaba or Airtronics....but until you are more certain about what is good, stick with the brands that are industry leaders.

Just my take. Good Luck!!
