Duds

Sadly my set had no range at all. Swapped units around and antennas with no improvement at all. Programming range dropped out at just a few meters. All the LEDS appear to be flashing correctly. I wrote a review a week ago but it hasn't been posted. ?
I have purchased another set of 915 mHz to replace these.as my first set worked well.

Dud Set of 433mHz Telemetry

Aug 31, 2018

Unfortunately my set was a dud. Kept losing communication then re-gaining and losing again. Most range I managed to acheive was about 60 meters and then after that no more than about 5 meters. I swapped units/antennas/cables etc over but no difference. Almost like the antennas weren't working at all. After many tries I gave up.
Hobby King credited without question so I ordered some 915 mHz as I already have some of those and they work well.

This item is very badly designed, it will make a lot of perturbations especially on the video transmitter and the OSD. This happens even if you put ferrites and use a separate power supply for this module.
Also it drains too much current to be used as is on a Smartphone.

It is possible to decrease the input power in the settings but even at a power lower than 100mW it will still perturbates the OSD and the video emitter.

Avoid this device, with the 433MHz antenna from immersion RC and a dipole antenna on the ground you will reach >7km range with the 100mW version from 3DR without perturbating your other transmissions.

First set worked for 2 days (ground testing), then one unit stopped working. HK replaced it swiftly. Second unit is working so far, but I suspect they draw too much power for all my android devices, and as a result, dont work on android. Ive had it working once for a short while, but more typically they dont even power up on the OTG cable and if they do, sometimes my phone/tablet will instantly shut off. Tried many OTG cables, 3 different android tablets/phones. I worked around it by connecting a bluetooth module to the radio, and powering those separately, then connect via bluetooth. Setting the tx power in Mission Planner doesnt seem to work. Build quality is mediocre, the case isnt even held together with screws and comes apart too easily. Cutouts for the connectors are a bit small, and connectors can fall out. Nothing you cant solve with some hot glue and tape though. Range not tested so far, but probably excellent based on ground testing results. Oh, and beware, servo's dont like these radio's, you have to keep this unit well clear from servo wires or they will go beserk.
