I've been ordering from HK for years. My last order was missing the backplate for the motor and instead there was an extra acorn type prop nut, to make up for the weight I suppose. This was the third time in the long long line of orders over the years so It's no big thing to me. Once I received servos that seemed to be for retracts (only moved full range or nothing). And another time the on/off battery switheches actually fell apart in my hand. So, for the many orders I've had three problems. Yes, sometimes new products seem to be junk. But, the cost has never been too great.
Should I tell you about my orders from, AMAZON, EBAY or even SEARS, or PENNYS? I other words, when people are involved in the handeling of products expect errors once in awhile. New products, take your chances.
My suggestion to everyone is to pay by PAYPAL, Credit cards or the likes so that you can have some recourse!!
