The option to save the models memories is with the PC tool EEPE (http://code.google.com/p/eepe/
True, I was forgetting that. When I'm testing the gear at home I often have the radio next to the WiFi router but FrSky does hopping so it doesn't get too much into
the router. Now a vTX static in one frequency emitting with 500mW...
For video I've been using 900Mhz up to now, but I'm goign to try 5.8Ghz because the antennas are smaller and easier to fit in the multicopters.
I got a HK Mini OSD, it's using some custom FW. The problem is that they have a AtMega88, so there is very few space. I've loaded in mine the alternative FW cl-osd and it runs fine but even tried to port the arduino OSD code from Dennis @ RCG but was no good due to the size.
But the version with GPS is pure trash... including me I saw several people where the wires in the GPS were loose of badly soldered. I had to open mine to fix it.
I did saw. I actually got one... and I don't want to talk about it!
Such a headache, my goal was more the TX as it fits nicely in the radio but it was a headache, tons of problems... eventually found out that during assembly someone
dropped a ball of solder on top of the RFM22B of the RX.
And I'm not the only one having problems, all sorts happening mainly due to bad soldering work.
Btw, have you ever tried the antenna diversity in the RFM22B? I was thinking in making a PCB with 2 antennas. It will require a RF switch.
