Jumper T16 ribbon cables
My current favourite radio and the one I use 95% of the time is the Jumper T16 pro.
I have 2 of these radios. One is the T16 pro V2 which has the hall effect gimbals, Internal module and USB-C / Charging module. My older T16 pro has Hall effect gimbals and has been upgraded with the internal module, foldable handle and USB-C / Charging module.
Although the T16 is an excellent radio, they have been plagued from the start with ribbon cable issues. I am a big fan of Joshua Bardwell's YouTube channel and from one of his videos I discovered that Jumper will supply a set of higher quality ribbon cables for free (you may have to pay postage in some cases) for a transmitter that is having these issues.

I emailed them and they advised me to contact one of their UK suppliers as postage from China was experiencing long delays due to the current Covid-19 crisis. They said that there may be a postage and / or admin charge but there would be no charge to the cables.
I contacted FlyingTech who were very helpful. There was to be a small admin and postage charge but this was waived as I placed an order with them for other stuff and they just included the cables in the order.
The order arrived very quickly and I proceeded to fit the new cables. One trick that I found very useful was to wrap a small piece of Blenderm tape around the points of a pair of tweezers which helped grip the ribbon cable tighter.
There are more pictures of the ribbon cable replacement in the gallery.

Some notes on the Jumper T16 Transmitter
Here are some notes about the Jumper T16 transmitter. Mainly things I've found while using it.
- Need to calibrate 6 position mode buttons when calibrating sticks, pots & sliders.
- Splash & Background image size: 480 X 272
- Model images need to be 192 pixels wide. Height does not seem to matter.
- It doesn’t seem to like filenames of more that 6 characters for model images (excluding extension) .
- After binding receiver, need to “Discover sensors” before they can be used for telemetry.
- Some receivers seem to need the protocol sub-type (e.g for DSM, the sub-types are "2 22", "2 11", "X 22", or "X 11") to be set before binding. Sometimes the transmitter picks this up automatically as part of the binding process.

Spektrum DX 7s
This is the radio that I currently use for my flying models.
Personally I like this radio as it feels robust and well built. I have tried some cheaper radios that felt as though they would snap if I got over-enthusiastic with the sticks.
