Re: airtronics rd8000 problems
there is no button on the receiver at all and the 2 battle switches are plugged into the receiver and they run the smoker and the l.e.d. lights they are activated on aux 1 and aux 2 here is a pic of the radio

Re: airtronics rd8000 problems
Dwayne , I did some reading a bit and dug up this thread, http://www.rcuniverse.com/forum/rc-r...-fm-print.html In it I came across this post " There is an additional problem with the 92185 PCM RX. The voltage where the rx shuts down is 4.7 volts rather than 4.1 volts (as all the other rxs made by airtronics) For this reason, 92185 rxs need to be run on 5 cell packs if they are in a plane with high current loads from servos. Airtronics does not easily give this information but I was able to get it out of them after a couple of bench observations under high current loads a couple of years back. " see what voltage you have at your RX . The MFU may be drawing too much (IDK) that might be a starting point .

Re: airtronics rd8000 problems
Dwayne, you are using the RD8000 not the RDS8000, thus you will not have any binding functions between the rx/tx. It is bound by the crystals.
What basic voltage are you using to power the MFU, i.e. 7.4 or 9.6 You can safely run an MFU up to 9.6 although 11.1 will work, the MFU is sensistive to that high voltage. (a fully charged 11.1 is 12.+ voltage) The MFU will then drop the voltage down for the RX. 1. Remove all the connections to the RX 2. Get an external power source for the RX and plug it into the RX (You can safely put 6.0v into the RX if you do not know the correct input ......most older TX run off between 4.0-6.0 volts) 3. Plug an extra servo into the any port on the RX 4. Turn radio on then RX and watch for any motion at all ***if you get any motion from the RX, then the RX/TX is talking 1. plug one item in at a time, starting with the MFU ***if you do not get any motion from the RX, turn the RX, disconnect the battery, and turn off the radio. 1. with the radio off, plug the extra servo into the RX and then the extra power source.....switch on the power to the RX and listen/watch for any motion. If you get any motion or noise, then you RX is good but not talking to you radio. Also, to piggyback off Mario, DO NOT run dual voltage to your RX. You can, however, run dual power so you can power your individual components. You have to remove the positive power lead going to the rx from the extra power source. All that component will need is the signal from the RX Hope this helps some.

Re: airtronics rd8000 problems
I appreciate everyones help with this. I went out today and bought a Spektrum dx6i with a new receiver and viola hooked up a few plugs and the mfu started up.i got power to the steering and throttle. Just have to set the rest of the truck up with the extra channels and i am good to go... i will be selling the radio with the receiver simply because i cannot readily get parts for it up here in Canada.it probably needs a set of crystals as you said that the binding is done through the cystals. It will be up for sale in the buy and sell section....Radio only for sale,not the truck
