A Quick Update
I was in the Bournemouth area this morning and called in to Westbourne Models and purchased a new Multiplex Cockpit SX R/C set.
My initial reactions are that it's very good, but a long way to go before I can fully get to grips with it, but a few points for anyone considering getting one of these sets.
1. The set consists of the TX, RX and 1 servo and nothing else, ie. no switch leads, RX battery or charger!
2. The lack of a charger is a slight problem as Multiplex use a 7 pin DIN plug which serves as a charger socket and for various other purposes, like flight simulator connections etc. No wiring diagram is included as to which pins are for the charger. The best option would have been to have purchased just a charger lead and use my normal Pro-Peak Prodigy charger, but Westbourne Models didn't sell them! I had to buy a Multiplex TX charger and suspect I will end up cutting just the plug lead off it, which is an expensive way of doing it. I have now worked out how to wire the plug, but 7 pin DIN plugs are not that easy to find.
3. The TX works fine with my existing Hitec and Cirrus RX's, which have crystals in them. Equally the Mutiplex synthesised RX will work OK with a standard Hitec TX.
4. Set up couldn't be easier as you simply set the desired frequency on the TX screen and then switch on the RX and it almost automatically sets its frequency to match the TX.
5. The receiver won't work if the RX battery is less than 4.7 volts at switch on. This caused me some confusion at first as I managed to try it first time with a somewhat dead RX nicad.
6. The TX won't transmit until you press a button on the TX to confirm.
7. The TX has no less that 3 separate timers. The 2 most useful are the run timer which starts when you activate the throttle and a countdown timer which you can set to sound an alarm after a preset time, such as anticipated battery life. The third timer simply records the number of hours the TX has been used and is ongoing up to 99 hours.
8. The TX antenna is rather long, although a shortened stub antenna is supposedly available at extra cost, but it does have a reduced range. The antenna is stored inside the TX's case when not in use.
9. It look as though any 40Mhz frequency can be selected and possibly into 41Mhz as well, which would be illegal!
10. The manual is very good but is entirely aimed at R/C aircraft operation and makes no mention of surface craft operation.
Hopefully users can add their ideas to the Forum to help others.
11. The TX sticks can be set up with ratchets or self-centering, with adjustable spring tension, via screws in the back of the case, which require the use of a Tork screwdriver, but fortunately one of these is supplied.
My next step is to set up the memories for each of my models, as each memory can be saved against a 6 character alpha-numeric name.
Plainly there is a lot more to learn, particularly as regards use of the mixers, electronic Y leads etc.
Hope this is of interest?
