My Jumper T16 is broken! This is a feature-filled transmitter that sets a great value point but after less than an hour's use, my has already developed a fault. It looks very much as if the microSD card interface circuitry has failed, causing the radio to fail on boot-up. I've not heard of any other units doing this so it is probably "Reviewer's Curse" striking again.
I will be doing a fault-finding video as part of the tear-down I promised in the first part of my review -- so stay tuned!
No, FrSky didn't pay or bribe me to make this video -- I simply believe in giving viewers the whole story, including when stuff fails.
