This summer my Batch 3 unit developed a problem. It would disarm itself…seemingly randomly. Upon re-arming, all, some or none of the motors would work (this was random too). Fortunately, none of this happened in the air. It took quite a bit of time to troubleshoot the problem, but I managed to track it down to an intermittent short in the throttle cable. I clipped the ends off of the old cable to reuse (it would be nice if the controller and throttle board had solder pads like on my quadcopters … it would make for a more robust build, and we would not be limited to the “plastic” covered wires). I ordered 24 gauge silicone wire…it had good reviews on Amazon and ordered 15mm conductive cloth fabric tape for new shielding. Here is a photo sequence of the build:
The unused IC socket near the bottom of the throttle board helps to hold the new cable tight. I did also add lots of heat shrink, split wire loom (1/8" and 1/4") and a bit of hot glue behind the cable where it goes through the throttle cover. I also added a bit of foam weatherstrip inside of the cover to help hold down the tiny 4 wire throttle connector. For me, solder pads would have been preferable.
I’ll add these photos to my build album for reference.
I’m so excited to have my X4 back! Happy flying!!
