"I use a button on my joystick to arm."

Chris Khosravi replied to Gursimrat Bawa's discussion Tailless UAV design
"Take a look at the Raytheon Cayote UAV. You'll find many pictures online to get ideas. I'm not saying it's a good design, but it's one of the few tube-launched UAVs that have pictures online available for the public."

Chris Khosravi replied to Maarten Heuvelman's discussion Controlling 2-Axis glider plane with APM2.6
"Your plane sounds like it is 3 channel? Throttle, elevator, rudder correct? I had an APM 2.5 in a glider just like this. Rudder servo is plugged into aileron output since it has the affect of ailerons. Nothing else needs to change and it's very easy…"

Chris Khosravi replied to Phil P's discussion Joystick with FBWA and FBWB modes.
"Yes of course. In fact I would only recommend using joystick in non-manual modes. Latency and resolution is simply not there for full manual (servo-pass thru control). Here is a video of one of my planes that I fly strictly with a joystick (no r/c…"

Chris Khosravi replied to Adnane ElSoussi's discussion Using multiple joysticks with mission planner
"I would also love to have 2 joysticks. 1 for controlling the vehicle, and the other to control a payload such as a camera. This may be possible using 3rd party software running in the background of windows, however it will probably take some effort…"

Chris Khosravi replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"Hi Paul,
All the info on how to do it is online in the wiki (this is how I learned):

http://copter.ardupilot.com/wiki/flying-with-a-joystickgamepad-inst...

One of these days I'll be sure to document better video of how well it works."

Chris Khosravi replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"If you read my comments you will see that you don't need to spend $250. You get plenty of range by buying a single RFD900 (~$90-$100) for the ground station, and a $15-$20 cheap 100mw china module for the aircraft. I get over a mile and retain 90%…"

Chris Khosravi replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"Good point. I actually use an RFD900 on the ground and use it for both telemetry and control. Have 100% success so far without any issues. Arducopter/arduplane is so dang reliable now, I have enough faith in it that I no longer use RC receivers…"

Chris Khosravi replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"I second the RFD900. I've been using an RFD900 on the ground and cheap $15-$20 100mw radios in the aircraft and I'm getting over a mile with 90% or more RSSI quality. With RFD900 on both air and ground, you can expect 20-40km of range. I'll never…"

Chris Khosravi replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"Here's a revision to my enclosure design. This one is intended to mount to booms(tubes), masts, etc. Will custom make any clamp up to 30mm for you (ad shows 20mm boom):
RFD900 Enclosure"

Chris Khosravi replied to Ferruccio Vicari's discussion Tired of batteries? Just go gasser :-)
"Looks awesome! I will give it a try once your custom software makes into the next official release of tradheli firmware.
Do you have any info on how you added a governor?, or are you not running one at all but instead a throttle curve?

Thanks
-Chris"

Chris Khosravi replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"Have you tried swapping your TX/RX wires? TX on ground radio should go to RX of FTDI adapter, vice versa for RX on ground radio. TX on aircraft radio should go to RX on Pixhawk/APM telemetry port, vice versa for RX on aircraft radio."

Chris Khosravi replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"Hi everyone. I'm a huge fan of the RFD900 data radios and have been using them for the past couple years. Over this time period, I have come up with a nice 3D printed enclosure for it. It can be useful for both aircraft mounting as well as ground…"

Chris Khosravi replied to Dmitriy's discussion Traditional Heli governor question.
"That's great to hear about 3.4. Will governor sensors work such as the stator gator? Any idea on when 3.4 will be released?"

Chris Khosravi replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"I use a 100mw on my aircraft and the RFD900 on the ground and still maintain 98% telemetry link at 1.5-2 miles. The link is so good I really have no reason to put an RFD900 in the aircraft."
