i was going to take out the left stick and put it on a seperate box for weapons. has anyone done this already or shouldnt i do it with spectrum. i did it with futaba 40hz but not sure if it will make a difference with 2.4 ghz. any advice please before i get my screwdriver.
No experience of doing it to a Spekky ...but I cant forsee any difference between the transmitter types.
Sam Smith has modified his for Tiberious. Sam wanted to use one of the switches on the top, but they were only two position which was no good for Tiberious - although i presume thats fine for your flipper.
If not, he got a potentiometre from one of our spare spektrums and put that on the same channel.
i plan to fit a power return but only when i need to use it so i will need a neutral position. did sam take out the left stick or just wire in the spare to the existing one?
The DX6 is basicaly a JR 6102 transmitter where the transmitting module has been replaced by a 2.4GHz board from Horizon Hobbies. All mechanics and regular electronics are just as easy to modify as if it was a 40MHz.
Th DX7 is a different storysince the conversion fro analog to digital is more interweaved than with the DX6, to get the latency down. The same is true for the JR X9303. That needs some figuring out.
i believe he swapped the two position stick for the potentiometre from a different spektrum and put that into an old transmitter.
Speaking on dx7, i have had problems in the last event, thought a BR reciever in one of the clusters was knackered, but it turns out it had lost it signal somehow with the dx7, rebound it and it worked fine for a bit then done the same again.
thanks guys :)
Apparrently it is possible to UNBIND the Spektrum.
1. On a model that is already bound and working fine, turn on the receiver as normal WITHOUT the bind plug.
2. Turn the transmitter on with the bind button held down. You can then let the button go but dont turn the transmitter off for at least 20 seconds.
3. Turn off the receiver and then the transmitter. The receiver must be turned off FIRST.
This exact sequence will cause the system to unbind. You can rebind it and everthing will be back normal.
speaking of DX7 and also binding, at leciester i had a br reciever playing up, i believe it unbound itself from the DX7 on 2 occassions, when i re-bound it, it would work fine, then it done it again later on. I found the DX7 takes alot longer than a DX6 to pair itself with a br reciever. not sure if anyone else uses a DX7. it may be a faulty receiver, not sure.

Im alright with the stick how it is buddy!
The DX7 waits during the bind for a signal from DSM2 receivers like the AR7000 and AR6100. DSM2receivers send a signal back to tell the DX7 that it is DSM2. If that signal is not received within X amount of time, the DX7 assumes its a DSM receiver and sends a DSM signal to the BR6000.
So binding to a DSM will take a bit longer on a DX7.
I dont believe the DSM2 receivers transmit anything. They are a receiver only. As I understand it, the DSM2 protocol is back compatible with DSM but the marketing hype is difficult to decypher from the technical hows and whys.
The DX7 does however have a feature called modelmatch. This means that when you pair receiver (a) with the transmitter on model memory (1) the receiver will not work if you use model memory (2). So if you have changed model memory, it is possible that the receiver needs rebinding.

DSM2 receivers do transmit during binding.

Thanks for posting that Leo! Very interesting reading!
So the newer receivers transmit their protocol version when they are binding. As a result, if you hit the bind button while switching on, the transmitter assumes it is bound to a DSM receiver and changes the protocol and the newer receivers would no longer recognise the transmission.
So if you use a DSM2 receiver you need to be careful not to knock the bind button during powerup, else the receiver may stop responding.
And it would also be important to note that by virtue, you cannot use a AR6000 and the AR7000 from the same model memory. E.g. If you were using two receivers in your robot from the same transmitter.
Both receivers would either need to be DSM or both DSM2.
That is 100% correct.
