RE: Engine trouble shooting?
Same story..same guy, Sumair.
Sumair bought my Used but never flown 14mz w/o rec. or modules. Then complained that it didn't come w/ a module and that it was dusty.... The first run of 14mz had a LCD that worked best w/ the stylus than your finger, so with the fact that he couldn't use his module from his 9zap and he didn't like the older version of the LCD, he claimed it to ebay and paypal as "not as discribed and Broken". Paypal is now putting together Felony charges on him for fruadulant representation of the items to get back his $1350, which he did and never surrendered the transmitter.
I believe the guy with the engine faced a simular account, especially since the poor guy had to go so far as to contact Sumair's club presedent. Good For You, good job!
