Dynam 7ch rx binds to 2602tx

Ok. I will finally be able to order a devo 8 this weekend. New credit card billing cycle! Will be able to do more than just poke around the emulator soon. Hit a major setback in my viperjet build yesterday that I hope to use the devo on. Had an elevator servo burried deep in the tail under the edf and thrust tube work on the bench and fail after everything was installed. Ripped everything down last night. PITA!! Hopefully my 150mph viperjet will be a mascott for deviation firmware soon!

Ok hopefully I can give some insight here. The gear ch is like a 7th channel add on to the standard 6 and is not proportional. They have used the throttle kill (gear) switch to activate a 7th channel. BUT, it does not appear to be proportional, it is NOT affected by the extent dial on Rx or anything to change its range on the tx, and you get either the throttle kill or the gear control depending on which transmitter you have - NOT BOTH. One tx I have that kills throttle on the gear switch does nothing on the gear channel. My 2602 tx runs gear on the Rx but has NO throttle safety ... I have learned the hard way with a few close calls on prop strikes. I cannot comment on aux 1 being pitch as I have not used any of the helicopter swash mixes in the 2602 tx but it should be proportional. Unless using a predefined swash mix in the 2602 tx, there is no way for me to operate it. Aux 2 is gyro control in the 2602 tx and is definately proportional. More on the "gear ch" with the 6ch walkera Rx - it does absolutely nothing to switch on the tx and therefore seems to make sense that its a 7th channel add on to a 6 ch system - not proportional like the other 6- and used either as a gear switch or a throttle kill depending on the tx. Let me know if this makes sense.

I have finally ordered a devo 8 by the way. I did not get the 8s as I have no need for telemetry and prefer the silver case. Do I need to install the upgrade module when I get the radio to use the filesystem you linked earlier in this thread or am I ok without it? I ask because the filesystem you referenced earlier for use with this "trial dfu" was the experimental build for telemetry right? Are you still using the trial dfu or have you changed it? Just want to know where to pick up once the devo arrives.

Awesome, looks like it will be an 8s after all. Just got an email from oomodel that they do not have the silver case 8 in stock. I hope this does not create a problem getting the order changed and actually shipped.

Ok now that I am up an running I am going to try to contribute here again. I tried the 2602 protocol on the 7 ch Rx last night. Phractured, did your last experimental release include the advances you made for 2602 protocol? If not, could I use the dfu release posted earlier here with the file system from the latest experimental telemetry build.

Where I am at now. The problem I encounter is that ch 6 is feeding back into ch 3. If if assign ch 6 to a switch - when I flip the switch my throttle goes full. I have to be very careful with this because if the switch is the wrong position when I plug a battery in I risk a prop strike. My 2602 tx was like this when flipping the flight mode switch. I had to physically disconnect that toggle after 2 prop strikes. (Luckily with small planes). I think the data you had to figure out 2602 protocol was collected with this switch in the wrong position. Makes sense for a heli for flight mode or pitch to mix back to throttle but no good on an airplane. Should I try the dfu posted earlier in this thread and do I need to change my file system?

Still have not switched to the dfu posted earlier in this topic PB but I can say with confidence I trust 2602 on 5 channels. I put the micros down and grabbed two full size planes this weekend. Both fly over 100 mph so any glitch would be extremely obvious. Took them up very high ... Out of sight for a second even. No problems!!!! I did notice if I use a virtual channel as a source for a mix on another channel ... It will not save the "reverse" state. Reverts back to normal direction after power off and back on. Other than that - aok! Still issues with ch 6 and 7 so I keep them off. Ch 6 feeds back to throttle and ch7 range of motion is extremely small.

Sure. Using a 2602 tx, channel 5 is just binary and is 100% on or off and used on a gear switch. This is functioning as expected with current dfu. Channel 6 is originally the pitch control for the main blades. It is fully proportional and was originally mixed to throttle automatically by a flight mode switch on the 2602 tx. I believe the original logs you received had this switch in the wrong position. You have ch 6 moving through a full proportional range - but it immediately cranks the throttle high without showing that output in the mixer just like the original flight mode switch would do. Channel 7 is the gyro control on a 2602 tx and is fully proportional. Using a 2602, one would have to be in the gyro control menu and use the V2 nob to control a servo with full range. It was cumbersome but it worked. It should be available as fully proportional. You have it working now but the servo only moves through a very small range - not the full swing that it should have. Where are you located - I could ship my 2602?

Question: you posted a revised dfu for 2602 protocal earlier in this thread but i have not been able to test it as I am not sure that it works with the latest filesystem (dsm2 and telemetry updates). I would like to try the revised dfu you made earlier but wanted to make sure i load the correct filesystem to go with it. Please advise if I should specifically test this one next:

"so 3 zeroed bytes, 3 missing channels, seems like a safe bet this is where they are.
Included is a trial DFU that adds 7 channel support to the WK2601 protocol. It is completely untested and may not work at all, but I'd be interested in feedback with any 2601-only Receivers.

Note. you need the filesystem (not dfu) from here:

Ok. Thanks. I have learned to ask first and install second.

I think documentation is key here. There could be a section documenting how a 2603 should be configured for now, and in the meantime gauge interest in the 2603 and decide if treating it as an exception is ok or not.

Please keep in mind while making config files or templates any of the primarily airplane only pilots using this protocol. I personally will be thrilled if you come up with an "airplane mode" for this rx. SO far it is already really close, I understand CH 6 is going to be out of the question for proportional response that is not linked to throttle, but otherwise the gear ch is useful for retractable landing gear and getting proportional response on ch 7 will be a huge addition.

IS there any hope after examining the tx output that the gear ch (ch 5) could be made proportional. If so, my suggestion would be to shut down ch 6 completely due to its strange behavior and treat the rx as if it were only 6 channels instead of 7. This would allow programming using deviation to proceed as expected for any user on a 6 ch heli or airplane.

I have another Walkera branded 6ch RX that is hard to access in a foamie biplane. I remember that something is funny about the upper channel assignments. I think they eliminated the channel 6 and it behaves as if it goes straight from gear to ch 7. Either that or they eliminated the non proportional gear channel. I can't remember which. I will rip it out this week and post the differences.
