I recently purchased the set FRSKY set with a D8R-II RX and DFT TX module. Also, I purchased the FLD-02, Sensor Hub and battery voltage sensors, GPS – a lot of things from you guys. However I had quite a few issues which led to the loss of my most appreciated FPV aircraft: I was flying a few 100m away in an rf low noise area. All of a sudden the tx started to beep indicating a signal loss, RSSI close to 0 and went into failsafe. I had no chance to recover the plane as it crashed in the jungle. On board were video cameras, video transmitter and a few other gadgets. I couldn’t believe what happened and checked the TX module. As the picture shows, the ground got disconnected/got broken. This is clearly a very weak spot in the tx side and probably after swapping the module a couple of times, other users will run into the same issue. It took me some fiddling but I managed to properly reinforce the weak spot to ensure a lasting and proper connection. I would strongly encourage you to improve the design of this connection. I have my patch antenna mounted away from the DFT module, connected through a proper coax extension. Without the ground, the antenna length match was off – completely – resulting in the range loss. Doing a ground check may not even have solved this simply because it’s an on off problem: sometimes there will be contact sometimes no, simply because the gap is no more than 1mm.
Prior to this, I already had some issues regarding this connector as shown in the picture. It came loose and had to be manually resoldered. Gladly I noticed this before flying. Clearly this spot again shows poor manufacturing in terms of soldering spots.
I would appreciate you evaluating on the discussed issues and what you are going to do in future to avoid these kind of problems. I like the FRSKY products very much and I would like to continue to use them. Regarding the loss of my plane which cannot be recovered, maybe you could find a way to make this up to me again.
Hoping to hear from you soon.
