I purchased a GWS 4Ch. receiver to build a Slow Stick for my 6 year old daughter, and channel 3 didn`t work. I then bought 2 GWS servos as well. Guess what?.. They didn`t work properly either! I called customer service, and was told to send them in for repair. AFTER they received it, I received a call saying I needed an RMA form, and a receipt. I explained it was purchased online, and I did not have one, and could GWS please fix it?. Customer Service pretty much said...sorry...unless you get one, we won`t stand behind it!...I tried to tell them it was NEVER used and that it was a PayPal purchase thus no receipt is given to the customer.....but...No good! It`s like the entire GWS corporate structure depended on them spending time to fix it so a little girl "could have a plane like Daddy`s" (not to mention the erratic servos I`m stuck with as well) There are too many other companies to deal with rather than go through this for a receiver that cost them a few bucks to make. It seems GWS would rather lose customers than make them!...Well then...So be it! Guys...don`t be taken in. There are LOTS of far better companies, with far better products and CS/Service than GWS. Give Hi-Tech a shot...You`ll be glad you did!
