Sounds like you have the two chs mixed together within the radio programming.

The instructions will explain how "mix" works and which one of the switches on the radio turns the mix on/off.

What radio do you have now?

[justin]

i brought the fysky fs-th9x did anyone esle got a battery with theres

quick google search shows its a rebranded turnigy radio should take 8 AA batts, like joe said you probably have a mix active, first thing is tell us what function you have plugged into what channel? like boom channel 3 etc, secondly what mode is it set in aircraft/heli/glider?

[justin]

just a update on this is that i got the boom movin without the track coming on but now i can only get the left hand track going and not the anther

the mode i hav it on is heli the stick mode is mode 1

i havnt change any of the function from wen i got it (factory set)

channel function r

1 esc
2 lower arm
3 boom
4 bucket
5 esc to pump
6 esc
7 esc
8 serv0

Hey i have this model, leave your sticks on mode 1, but the remote should be in glider mode not heli and mine is in ppm from factoy not pcm

now my model is version 1.5 so a couple thing's may be different like my light switch etc. but if you give more info i may be able to give more help

and for your tracks (im assuming your replacement remote is this same as the one you broke, custom with the spider legs)

goto menu, then function settings, goto last one aux-ch should read as follows

ch 5 - thro hold
ch 6 - hov pit
ch 7 - hov thro
ch 8 - gear
ch 9 - null

ch 6 & 7 are your tracks, ch 5 is your pump ch 8 on mine is the fourth servo pressure release (dont know if you have same version)

other channels are as follows

ch 1 - ail - boom swing
ch 2 - ele - front boom +/-
ch 3 - arb - main boom +/-
ch 4 - rud - bucket +/-

and you should have three mixes active one for each ele, arb, and rud in that order all masters, slave for all is aux, offset for all is 100, uprate for all is 100, onrate for all is -100, all sw = nor

for e. point adjustment (3rd in function list), the 5th one (flp) is your pump mine is 024% on 000% off from factory haven't adjusted anything yet

if i can be of any more help let me know
Trevor

*edit* the slave mix for all three mixes is the first aux not the second

[tman1986]

just thought i'd add, this is what my end point adjustment list looks like

ch1 - ail 120%120%
ch2 - ele 100%100%
ch3 - arb 100%100%
ch4 - rud 120%120%
ch5 - flp 024%000%
ch6 - flp 120%120%
ch7 - aux 120%120%
ch8 - aux 000%120%

this is how it came from the factory i haven't made any adjustments yet but in the display screen not all bars are hitting there limits, so i think it needs fine tuning but the important ones here are ch5 and ch8

again if you need anything else let me know
Trevor

Ok, so I have them 4200XL and there's a problem with the radio. I have to switch it on and off numerous times before it works. And if switched on, not everything works. RC4WD is looking into it, but takes some time. So I was searching forums for people with the same problems and found this post.

When I check the settings mentioned on my radio, I notice it doesn't have settings at all. Everything is set to default. So I try to set my radio with the settings posted here, but have a question. For the Mixes, there's a State-setting . Either INHibid or ACTive. Which one do I set?

And then the E.Point settings. I can't change the value for a couple of channels. For ch5 - flp 024% / 000% I can only set the ON value (024%). Tried all switches and levers to get to the OF-field without any luck.

Same problem with ch8 - aux 000% / 120%. I can set the OF-value (120%), but not the ON-value.

Is there a work-around for this?

Just wanted to mention this, I had a servo for the boom that before it went; seemed to be causing all kinds of odd stuff like tracks going backward cab turning until it stopped and I replaced it..now all fine.

I had same problem with mine, two different times. Each time a servo went bad the rest of things went weird, pump motor revved up/down, tracks moved ect. Thought the radio had issues but found to be servo related both times. Tower pro servos in mine. I don't quite understand how the feedback from a servo could translate to radio, but it is a cheep (less expensive-fine for what it is) radio.
