Frsky 2.4 Conversion
Richard Boyd:
Hi Bill, as we were told at the time, " once you modify any tranmitter you void the manufacturers specifications"
In our case we adapted a module to fit a multiplex tranny. The CE mark was void according to the authoritys.
We argued a point on the first edition modules that the module had expossed wires and in its self was not safe , nor did it meet the standard required for a CE mark.
The company that made the modules recalled all the modules and supplied a module with no wires on the exterior free of charge.
The new modules have the arial on the module as pictured in Freds post.
THIS WAS NOT A MULTIPLEX MODULE BY THE WAY !!!!
I think there are different rules applied to transmitters than receivers .

Fingers crossed for no accidents then! :?:
If I could afford it, I would go the full Multiplex route, but it's Very Very expensive cmpared to everything else apart from Jeti
& Weatronices. There was talk of a Spektrum module for the 3030, but I've never seen one
ps In ths States changing Xtals voids their insurance!
Fred:
Bill,
Can you post the schematic here ? :D
I think I'll move my Royal Evo to 2.4ghz too... Then, MC3030!

Why move to 2.4 anyway !
You now have nothing to blame for crashes.
I am going back to 35mhz.
I do still use 35mhz and I'm well pleased with the signal.
I had to buy a 2.4 system as some competitions insisted on using it.
Spektrum was the only light weight receivers at that time.
Airtronics would be my choice of system if I were to go into 2.4 again
:wink:
billscottni:
Moving because there are now too many "rogue" flyers out there. I may only use 2.4 on bigger, more expensive stuff which is why I'm doing it this way. There is a switch available, that once everything is inside the TX case willl allow me to swicth between 2.4 & 35.
On the insurance note, I checked the unit and it has a CE mark on the back. Not sure if that counts for much?
Fred, I've emailed the pin outs ,but found this on converting a Cockpit on the T9 website
"Conversion for MPX Cockpit SX Documented by Peter Barnet:
To use the FRSKY V8 hack module with the MULTIPLEX COCKPIT SX transmitter will
require the following items:
(1) a 7- pin din plug
(2) a small plastic box
try Maplins for both of the above.
For the sake of simplicity the pin numbering of the din plug is as follows :
From the inside of the plug eg the solder side, the pins are numbered in a clockwise
direction starting from the left hand pin which is no. 1. Then following around in a
clockwise direction to no. 7 which is obviously on the right-hand side.
Solder the signal wire to pin no. 3.
The red wire to pin no. 4
The black wire has to be soldered to pin nos. 5 and 6
Insert the module into your chosen box, drill two holes in the box to take the
binding switch and LED. Basically that is the conversion over with ... you can
attach the box to the back of your transmitter with velcro or you can build it into
your transmitter tray as I did.
Fit the 7-pin plug to the charge/trainer socket on the top of your transmitter and
switch on. The LED on the module should glow red and the display on the transmitter
should read DSG which shows that the transmitter thinks it is running a flight
simulator programme. A second press on the transmitter jog wheel brings up the
normal operating screen for the transmitter as would be if you were operating on
35mg. Obviously there is no 35mg being radiated from the transmitter."
