How much does it cost to get it "checked out". I found one website that still has them new with the syntesized receiver for $450. I have found a few on here but need to know if it will save me any money by the time I get it checked out. I looked at the 7C 2.4 some more and realized the receivers they come with wouldnt be adequate for the channels I need. 6 for servos 1 for kill switch and I will be putting 2 Rx batteries one for backup. I dont like the idea of y-harnessing a battery and servo. If the receiver had 7 channels and a battery slot it would be ok. As far as mixing I dont plan on ever going any higher than 50cc and dont plan on doing a whole lot of mixing, just the 2 aileron servos and 2 elevator servos. What would be a good price for a used 9CAPS PCM with PCM receiver?
