Since I have had nothing but excellent service from Horizon I just have to ask, did you buy it new from the local hobby shop or mail order or is this a new in the box ebay of RCU purchase? If you bought it from a dealer and have the receipt I think you will find they will repair any damage that the engine may have that is a result of a defect. If you don't have the receipt how are they to know you are not the 200th owner of the engine?
