Nicky Strahan Posted June 26, 2016 Share Posted June 26, 2016 Hi Mike, I have a considerable collection of Digifleet, some converted to 2.4ghz. I have a PCM-MX7 manual which I can scan for you. Send me an e-mail and I will get it to you. I will look through my boxes for a PCM reciever and crystals, should be plenty of both!!. Nicky.

Nicky Strahan Posted June 26, 2016 Share Posted June 26, 2016 Digifleet PCM has a 1 second failsafe period, which is longish compared to "modern" sets, but you can set a selector switch in the transmitter for "failsafe" or "hold". If you use "hold" the reciever keeps all servos in their last position until a good signal is obtained. Nicky. Quote Link to comment Share on other sites More sharing options...

Frank Skilbeck Posted June 26, 2016 Share Posted June 26, 2016 I have some tx and rx crystals, not sure what numbers though. I'll check and post back. Quote Link to comment Share on other sites More sharing options...
Mark Agate Posted June 26, 2016 Share Posted June 26, 2016 Hi, I have 2 PCM receivers and quite a few pairs of Xtals. I wrote the software for all 3 Fleet PCM systems, so can hopefully help fill in the blanks if you don't have an MX7 manual. They were great systems in their day (much better than the Skyleader system, which used a German micro, and had very slow response times by comparison). However, the RF circuitry can drift with age, and I never did know how to retune it! I always use 2.4GHz now of course... Please pm me if you want more info - [email protected].

Trevor Crook Posted June 26, 2016 Share Posted June 26, 2016 I've still got my Omega Tx, the last Fleet design. Alas, I've got rid of all my Fleet Rx's as I've standardised on the Futaba/JR servo plugs, and have kept a couple of Schultz Rx's - not flown on 35 for some time though. Mark makes a valid point about the tuning, although I think the circuitry is quite stable and the standard range check should show any problems. Of more concern would be the state of the batteries. As well as a battery health check, the wiring and pcb should be checked for signs of corrosion. Quote Link to comment Share on other sites More sharing options...
Trevor Crook Posted June 26, 2016 Share Posted June 26, 2016 Oh and Mark, well done for the excellent job on the software. The Omega uses a simple row of leds to program and display 10 model memories (Futaba had 4 at the time) and was a very cost-effective alternative to an lcd display. I helped Derek to write the manual as I could do it from a user's perspective. I still think the ability to set the failsafe position of all channels while in flight has never been bettered.

Michael Coff Posted June 30, 2016 Author Share Posted June 30, 2016 Thankyou for all the replies and help from the forum members I've learned a bit more and will now get this older equipment used again... I know we are all keeping up with new technology but some of us wish to restore retro models and use the original radio equipment from that period.Kind regards to all.Michael Coff Quote Link to comment Share on other sites More sharing options...
onetenor Posted June 30, 2016 Share Posted June 30, 2016 Re 35mhz Xtals. I have a Sanwa Rx 6 Ch minus a Xtal If I put in a Sanwa xtal; of a number the same as the one in my Futaba Tx would that work? Also how do you identify which is the battery socket on an unmarked Rx? Thanks guys John Quote Link to comment Share on other sites More sharing options...
