Cool
Still waiting for my second set...

The cut trace, resistor and wires are my Frsky mod without level converter: viewtopic.php?f=23&t=430

Should all be done directly through USB somehow...
Maybe turn the 9X into a standard HID?

I got a stock email this morning while I was in front of the PC, so I followed the progress... Started at 66, and went in about 15 minutes.

I am talking of the receivers that have PPM out (D8RSP, D4FR, D4RII), typically used to transmit all channels on a single wire to multicopter boards, OSDs or such. They generate a PPM signal with a fixed frame length of 18ms, like for the servos, whatever the PPM is set to on the transmitter. Those ...

OK, good news, got the HFM12-MX happy in both 7CH and 12CH modes, confirmed working with 2x FrSky TFR8S, all 12 channels are available and work perfectly fine. As for settings, I'm on PPM 12CH 400u 28.5ms POS. I swear I tested something like this before and 7CH mode didn't want to work, but now it d...

If it can help, my solution for FM:
viewtopic.php?f=40&t=527

I did another test, and come to some worrying conclusion about the PPM out of FrSky stuff. What I said about 8 channels at 100% not fitting in the 18ms frame is really serious. It's usually considered that the sync pulse of a PPM signal should be at least about 4.5ms. With that 18ms frame, this gets...

That's not of much use with a rotorcraft though, as you're close to hovering "throttle" most of the time, and more importantly also during landing. You'll be exceeding the threshold only after you've landed, which defeats the purpose

It won't count when you are flying your heli upside down with your pitch stick between about -93% and -100% - which normally shouldn't be more than probably 1 second in a whole flight!

That was easy to check as I already had my scope out anyway. Tha answer is no. PPM out on a D4FR or D8RSP will indeed follow the setting on the 9X IF you choose 4,6 or 8 channels, but doesn't accept more. Pretty much expected, as FrSky receivers enforce a too short 18ms frame rate in their receivers...

From some recent search, the FrSky GPS is already pretty much the cheapest you'll find. The module alone can be found for a few $ less, but then why give up the ready made cabling/packing and have to do that yourself to save $5... The Locosys module I use also has lower performance than the original...

Everything should work fine without module. Can you take a photo of your mod? Sounds like you wired the connections in the wrong place...

Yeah the case has doubtful attributes. Firstly they made the (usual from most manufacturers...) mistake of putting the strap hook above the power switch instead of trying to putting it as close as possible to the radio's CG. Then (when you use FPVC Advanced) the large screen you're likely to use in ...

Ooh, motorized sticks!!

Only 1 minute of seeing the thing in an otherwise very boring video, but it's already better than nothing...

Ideas on where to get it, cheap?

Missed that post, sorry.

But I guess you don't need the answer anymore now

OK. I had understood you meant "with only one transmitter module".

OK. I read too quickly and understood you had the magnetometer on the board but as a separate IC, thus taking more space.

What options?

Awesome! I'll need one...
The only thing that makes me hesitate is the size, I'd really have hoped for 35x35mm or something along these lines for the micro thingys...

I'll have to be one pushing for the MPU-9050 to save space

I read until about this point .... Hello all, ..... Other options that are removed in favor of simplification are: 1) Limits - all limits are set to -125%..125%. This gives the full range of motion. Reduction in movement can be achieved through the Expo/DR menu . 2) The E xpo/DR menu was removed as...

Frankly I guess that buying new meters will be easier and cheaper than getting isolated converters or stuff like this... Something like this kind of standalone meters for example: http://www.ebay.com/itm/Digital-Voltmeter-Panel-DC-7-5-30V-LCD-Car-Electromobile-Voltage-Meter-Blue-/280855921041?pt=LH_...

How do you power your 9x?
That's the only thing on the 9x itself that could affect range. Anything else would be module/antenna/receiver-related. The 9x only provides power and a PPM signal. If the module transmits and servos work the signal is there. So the 2nd only failure possibility is power...

No, no HW mods, at least not yet. The unused pins seem to be unconnected in the module. I still haven't been able to make the module happy in 7CH mode. I haven't yet actually tested the module transmits properly in 12CH mode either, as my receivers are still somewhere in the mail system. I wanted to...

My thought is to use 2 HK uebc   type modules in series to make 10 volts. That certainly won't work. All hobby UBECs I've seen have a common ground between input and output. So putting 2 in series would just create a nice short circuit :) What's the voltage the meters are supposed to measure? If it...

OK, then no need to look further. The already low supply from USB with the added load of the module will certainly bring the board voltage down to brownout reset levels.

How is the radio powered when you try to flash? Looks kind of like if there was no power. If it's powered through the usbasp, then try to desolder just the power supply wire from the DSM module, and try again. If it works, then the usbasp can't supply enough power. That wouldn't surprise me, because...

This will only come once FrSky supports it (planned, but no ETA).

Just use a curve for the front motor.

The real deal here is that info on the GPS thing is scattered all over the place I've made a thread when I was looking for the same FrSky GPS info, didn't really get it from here but posted my results: http://openrcforums.com/forum/viewtopic.php?f=23&t=438 Should have all you need to connect an...

This Wiki page is however about feeding the 9X with direct NMEA, while the OP is talking about connecting a GPS to an FrSky hub/receiver.
