Stay away from the OrangeRX LRS modules. They are not very reliable. I went through a bunch of receivers and eventually also a TX module, before switching to DTF UHF.

On the receiver side, it's also worth checking out the Brotonics LRS receivers.

Good info, i dont mind spending money on good gear, the UAS will likely be in the $5000-8000 range depending on if the FLIR is on it or a DSLR etc so itd be ashame to risk it on sub par gear. Let alone the hundreds of hours of work/development. :/
Any experience with Holybro gear?

Only word of mouth and it seems stable enough? I have 2 3DR pixhawks and a Hobbyking clone and the Hobbyking one has performed well.

I'll eventually switch over to the Pixhawk2, but this heli project will be on a shoestring budget . It's not always the cheapest way of doing things in the long run, but it allows me to make mistakes without breaking the bank account (and marriage).

Virtually all of these platforms use a module from HopeRF as the transceiver and the ones that don't use basically the same circuitry leveraging a Silabs RF modem chip but just on their own PCB. Probably the biggest issue with reliability is the quality of the assembly, soldering etc. The Orange TX for example placed an RF connector so close to the RFM module that if it rotates, it shorts out the RF.! Aside from that area they are all virtually the same technology and therefore the same capability/limits. The products I first mentioned from RFDesigns also use Silabs tech but have a much more powerful processor rather than what you find in a lowly arduino.

Well, just bought a Protos 500. Should get it next week.
Build should be simple, but I still expect it'll be a few weeks before I get it in the air.

I read the first page and will go through the rest of the page. I have been getting more comfortable with Pixhawk 1 on a hexa and love the power it has. There is so much to do.

I've mostly completed converting a Protos 500 and have posted a blog post here for those interested:
http://discuss.ardupilot.org/t/tradh...rs-pov/15236/2

I'll document the tuning process, etc as I move along.

Nice work!
Glad to see interest in pixhawk/w traditional heli. Looking forward to posting my own build coming up.....when the Pixhawk 2 finally gets here, so this is quite encouraging..

Those of you on the RFD 900 radios on Pixhawk 2, is there any appreciable lag? I'm hoping to use these radios for direct control. I've read they will provide noticeable lag compared to a standard 2.4GHz Futaba etc.

The plan is autopilot missions with joystick control when I need manual control
