...pretty good so far
As I mentioned before, I've recently got an FPV system to complement the Mobius, consisting of a Docking Station with integrated FT592 transmitter and a RX-LCD5802 monitor with integrated receiver and battery.
This works straight up with the FT592 transmitter, however a little trial and error is required to get a frequency which is free from 2.4GHz interference. While there shouldn't be any, it can happen if there isn't a solid link between Tx and Rx.
After having tried several combinations, I've settled on channel D3 as suggested in an online forum, and found it to provide solid video quality up to around 800m, when it starts to get grainy. Ultimate range is around 900m, with the interference bands appearing and the video losing colour.
Worthy to note that the Mobius doesn't have to be recording to output video, and that likewise it will not switch off with the power input via the integrated voltage regulator. Also, if you do have your Mobius recording and the card fills, there's no fatal error. In fact you get a warning displayed on the monitor but you can carry on flying.
So I'm pretty happy with a solid 800m range from this mini system. However, as I'm wanting better range than that, I'm going to try a helical antenna, although I'll be getting a budget version as I'm not going to spend $100 on a copper spiral...
...to see if I can sort the aileron issue
I had a go at trying to fix my other transmitters issue with chatter on the aileron control. After having seen instructions on how to disassemble the DX6i while I was reading through that controller's instruction manual, I bit the bullet and decided to have a go with the other.
There are six screws at the rear of the unit which need to be undone, then you simply pivot the back down at the bottom and lay it down flat. There is sufficient cable length to make this easy, and it's obviously how they assemble it.
What was immediately clear, however, was that replacing the potentiometer on the aileron control would not be easy - it's well integrated and unfortunately not easy to disassemble. That's why there doesn't seem to be any spares on offer, at least for this particular unit, with the exception of a replacement antenna, which simply slots into place.
...put a pin in it
The pin had somehow fallen out of the antenna joint on my DX5e, meaning the end piece would often come loose while setting the angle. I wasn't sure where I could find a replacement pin and didn't want to have to buy a whole antenna replacement kit.
Foraging around in the cupboard I came across a cheap household fasteners kit, which included a slim black nail, a near perfect fit for the hole, slightly tight so it wouldn't fall out. It was a little too long, but a quick trim with a pair of side cutters sorted that out.
Now the DX5e's antenna's sorted out, I hope I can fix the chatter issue with a bit of a clean-up of the aileron potentiometer...
