RE: Futaba 14MZ support
Our flat rate for a system check of a Futaba 14MZ system (includes transmitter, receiver, four servos, and receiver battery pack) is US$87.50, and includes no repairs. That's just to check the operation, calibrate the transmitter, and to check/adjust the tuning of the transmitter and receiver. Servo operation is checked and the receiver battery pack is cycled.
If you need more work, it all depends upon what needs to be done. Please be aware that replacement of the case can cause a few hundred dollars in parts and labor because it's not an easy task. When you get into complex transmitters, such as the Futaba 12FG, 12Z or 14MZ, nothing is easy, so costs could add up. For any kind of proper estimate, we need to see the transmitter. Any number given to you over the phone or via email can only be a wild guess and quite inaccurate. It would be easier to tell you that it will cost $500.00, and then wind up sending you a bill for the actual costs that would likely be much, much lower.
