I am really hoping someone has had this same problem before, and found a way to fix it, or has any idea that can help me out here, I am kind of in a desperate situation.
I am going to write in a sort of "process of elimination" style and highlighting components that might be important, so please bear with me.
After finishing writing, I realised that this is a massive post, so here is the executive summary:
JR XP662 (MAX 66 ADT) 35 MHz transmitter, all 6 channels work fine with the stock receiver, after installing the FrSky DHT 8CH DIY Compatible Telemetry Transmitter Module to convert to 2.4GHz for my new 250 racing multirotor, all channels are working except pitch.
I am pretty sure it is not he actual remote, or gimbal or new compatible receiver.
And for the people that are willing to read through all of the details, please see below.
I have a JR XP662 (MAX 66 ADT) 35 MHz transmitter, which was Mode 1, but I converted it to mode 2 by changing it in the software and then moving the ratchet plate from the right stick to the left. All of this works perfectly, as I have an old JR R700 receiver connected to a small plane and everything works fine.
I am trying to convert my JR XP662 (MAX 66 ADT) to 2.4GHz using the FrSky DHT 8CH DIY Compatible Telemetry Transmitter Module. (It is the only transmitter I have, I just received my first multirotor, an Eachine 250 Racer with CC3D on LibrePilot, and I live in Namibia, so anything I order from abroad takes 2 months to get here, and I end up paying about 70% extra on VAT and import tax.)
After connecting everything up, and I am sure that all wires were connected up correctly (its just the red, black and yellow that needs to be connected), I have a problem where my pitch (right stick up and down) is not working, even though all other controls work fine.
I am pretty sure that it is not the new receiver (FRSky Airwolf RX-F801), because when I swop the wiring from te receiver to the CC3D, say pitch and yaw, then it is still the "right stick up and down" that is not working, i.e. the pitch in LibrePilot will register when the yaw stick is moved, but yaw will now not register when pitch stick is moved. So to me this all points to the problem actually being with the "right stick up and down", and not the receiver or CC3D.
But, what is really weird to me is that when I again disconnect the FrSky DHT and reconnect the old 35MHz, then everything, including the "right stick up and down" works again!!!?????
So to me everything points to the FrSky DHT module to be the faulty item, but what I find very weird is that when it is installed, literally everything works except for the "right stick up and down", All of the other 5 channels work perfectly, which is just so weird to me.
Just to explain what the pitch actually does, when I try to configure it in LibrePilot, it does not register any movements I make with the "right stick up and down", but makes really random blips from the 50% (where it seems to be resting), to 100%, it does almost look like the random blips correspond with the blinking blue light when the CC3D is connected via usb, but after observing it for about 10min, I do not think this is the case.
I really hope someone can help me out, I really dont want to wait 2 months for a new transmitter.
Thanx in advance for anyone having gone through the effort of reading all of this.
