Paint shop before it's done Now it's time for the duanting task of figuring just how I want all my controls to work for 2 different crawlers EDIT APRIL 7th Momentary Crab Ail d/r switch to Upper silver button Momentary 4WS steer Mix switch to lower silver button 3 way SW for 4wd, 2wd, DIG installed next to trigger for thumb control-> Elev Ch. 2nd steering wheel mounted on the side-> Rudder ch. Ch 4 Elev 2nd Throttle Trigger -Switch to select between Elev DIG or 2nd Throttle. Ch5 Gear switch Ch6 Aux switch (flap) Bind button and attaching the 2nd wheel Last edited by toy4crawlin; 04-07-2010 at 06:44 PM. |

| You won't miss that radio! Yeah only need resistor for converting a proportional channel (Thro, rudd, Elev, Aile) to 3pos. Pretty well any value resitor (within reason) so long as it is the same on both sides will work. Kieren |

Oh sorry I missed it but you won't need resistors when you combine 2 standard DX6i switches. Like if you put to mix switches on the one 3pos toggle for rear steer. Kieren |

From what I have read, I need a 2.2k resistor on both sides to come close to the 5k pot. 2.2x 2= 4.4k also needed on a pot if you are going to mix it. other wise it will wonder off. using the resistors keeps it centered Quote:
I am copying bits and pieces of info from Clockworks and from pm to try and put the puzzle together. Any idea why he says to get so many different types of resistors ? where are they hidden. ? So far I know that I need to use a 1k or 2k mini pot and wire it in series with the main pots. Problem is, if you look in his pictures I only see 2 wires, 1 middle, 1 side. So I am confused Do you have all your pots and resistors figured out ? | ||

Ok this is clear cut! 1. You don't need resistors when putting two standard DX6i 2pos switches into a single 3 pos switch(by removing the wires from the 2 pos of course) 2. You need resistor ONLY when you are place 3 position switches in the place of a POT in either the thro, elev, aile, or rudd channels. They are also used to center a channel when the switch is in the off position. 3. You will only need one resistor value, somewhere around 2k5 whatever you can find. For me I could get 2k6 easily so I went with them. 4. I am not entirely sure what you are doing with mini pots? But anyway they can be used as a form of epas (look up the old TQ3 thread) and yes they only use the 2 wires through the pot. And yes I have all my pots and resistors figured out. Would you like me to put up a final diagram? It is kinda confusing but remember proportional channels + 3pos = resistors. That should be the only time you will use them, since your not dealing with dual ESCs. Kieren |

mini pots (trim) clockworks said to use them on the main channels to adjust them because the pots in the pistol case do not move the same amount as the Sticks. that's what I understand anyway. he mounted 4 of them in the battery tray. but I only see 2 wires to each and not 3, maybe the 3rd terminal is std grnd and is series across the 4 and so just one extra wire comes back to the board that I cannot see. so you are not using mini pots ? |

I am not using mini pots as the do not 'add' to the throw of the channel, they only can reduce I believe. Plus the DX6i has EPAs built in. Alot of clockworks stuff I don't understand, so I really just used it as a proof of concept I have designed my wiring from the ground up with the help of clockworks, more so than his original thread. Basicly I call mixing with switches pyshical mixing. Basicly it simply uses the switches to either remove or modify the signal to the radio channel, when they are put inline of the POT and radio board. Only thing is it requires you use on proportional channels. My dual ESC dig set up is pyshical mixing. Kieren |

I added a 1K resistor to the positive side of the steering pot. The aileron channel is now almost centred when I look at the "monitor" display screen. When I use a mix, the rear servo just moves slightly with the steering at neutral. I'll have to get a miniature 1K pot and wire that in series with the main steering pot. By tweaking the mini pot, I should be able to balance the aileron channel perfectly, so the rear servo won't change it's neutral position when I engage a mix. I think the problem is that the KO Mars pot isn't exactly centred in it's resistance range when the wheel is centred. It doesn't matter for normal steering, because you can adjust the subtrim and travel to get everything working. Problem is, a mix uses the physical stick position of the master channel to control the slave channel, not the trimmed position." Quote->[CLOCKWORKS] So you have wired the main ch's and found you dont need the mini pots ? i take it UNderstand your mixing part though, Good work !. is this 26 awg wire or 24 ?

Mounted rear steer steering wheel, but I had to cut down on the Switch pcb board a bit but I can still solder on my power wires direct to the switch pins. I also carefull cut into the PCB to separate the poles so I have a Dual pole Power switch which is need for the DX to keep the memory. I will build up styrene to hold the steering bracket to the rear case but it fits and has a spring return. Wheel donated from my old Futaba Junior. Working on Styrene box for PCB today Last edited by toy4crawlin; 03-25-2010 at 01:30 PM. |

I get what clockworks is saying, he is just saying that he needed those mini pots to trim his rear steer since when the servo is in a mix it was not responding to trim on the DX6i. *I think* Not sure why this is though. I will try it out and if nesecary I will put some in and I will let you know If I needed them. Looks like your case is coming along nicely Kieren |

? In looking at making a 3 way switch, is it best to use the Gear and Flap together so you can adjust the Travel and trim ? and that way you can use Elev & Ail for a mix (4ws/ Crab) since the master Front steer Ail has a travel & trim adjustment directly on it. Not sure whether to make the Elev stick into a 3way or make the Gear & Flap and 3 way, What do you think? use for 4wd-2wd-DIG Function Also , do you find it easier to use in Acro mode instead of Heli mode ? in heli mode the pitch is hard to understand how to use, where as in Acro mode you can easily adjust Gear and Flap travel and trim. I love lots of switches/options but in looking at what switches I need, it's not much at all like clockwrks. only have HUge thanks again Thinking out loud: If I need a 3 Way to run 4WD-Far left pos--2WD-middle pos--DIG- far right position. It looks like I would convert Gear & Flap to a 3way So I can adjust the travel and trim for each side, Or can the ELev Ch be turned into a 3way and accomplish the same task, what do you think ?

For me this is what I will do Elev - front throttle Rudd - Rear throttle Aile - Front Steer Flaps - Rear steer Thro - 3 pos switch Mix one - Mix Mix two - Aile D/R Gear - 2 pos For you, you could put your on/off/mom switch on rudder since you don't need dual ESC. Gear and flap mixing is kinda annoying to make it into 3 pos, plus your already using your mixes for rear steer. Also plane mode is WAY easier to understand for me than heli mode. Kieren |

Just use D/R and mix switches for mixes, save your proper channels. You can get the channel to do whatever you want it to buy feeding it the right signal. A 3 pos switch will move from one side through to the other, so will any pot? Kieren |

Mix switch is the throttle hold/mix switch at the back right of the contoller. Kieren |

Sweet !. EDIT:INfo Corrected MIX will be my Rudd-Ail (Crab steer) Ail D/R will be Rudd-Ail (4WS) 1/8 Scale buggy Ch-1 Aileron = Front Steer Ch-2 Throttle = Throttle Ch-3 Rudder = Rear Steer-proportional Ch-4 Elevator = 3 way switch 4WD, 2WD, DIG] *Ch-5 Gear. Avail (lights) *Ch-6 Aux. Avail *Rudd D/R, Avail *Ail D/R, Avail Mix = Silver momentary on grip 4 Wheel Steer Ail d/r = Silver mom above thumb Crab steer BERG: Ch-1 Steer Ch-2 Throttle Ch-4 Elev. DIG DUAL ESC: Ch-1 Steer Ch-2 Throttle- Master throttle Ch-4 ELevator- Front throttle (pinky finger) Proportional Ch5 & ch 6 DIG modify to a 3 way switch or 2 Momentary buttons using Gear & Flap channels FrontMix =silver mom Front throttle 100% / Rear 80% Mix 2 = silver mom Rear throttle 100% /Front 80% OR Possibility Mount a Throttle trigger upside down in battery tray and use pinky to operate Other Cars/Trucks Program for Standard 2/3 channel operation Heli/plane = Umbilical cord back to DX6i Stick and stock switches Why not Dual Trigger throttle Last edited by toy4crawlin; 04-14-2010 at 04:45 PM. |

I see only one flaw with your wiring write up. You can't use Rudd D/R for mixes. It is not in the list on the DX6i. I thought you didn't have dual ESC? Anyhoo 2 throttle and 2 steer is a lot easier with sticks that will be, atleast in my opinion Kieren |
