Hello, Have a 3DR Y6 BNF for sale, get it as a kit bind & fly or cannibalize it - cheaper together in you can pickup in NYC area, or 'a la carte'. Sad but it must go! A lot of fun to build and fly, flies great - Here's a vid of it in action:Oahu,…

Hello,I'm helping someone install an analog airspeed sensor with the pixhawk, the wiki says:The “airspeed” pin 15 is located on a 3 pin DF13 connector on the Pixhawk board.This pin can take voltages up to 6.6V (it has an internal voltage…

"Hi Thomas,
In the video I go into detail on all the individual components and also go over their layout in the fuse (with a closeup). If it's not clear i'll gladly take some pictures a bit later when I'm near the wing.

The batteries i've been using…"

Been having a lot of fun with the Mako wing & Arduplane (APM), here's a short video of the build & some FPV flying. Really happy to see Tridge keep APM support in 3.3!Params: mako autotune paramsHigh res images of fuselage:

"I've also had the same issues with the RFD900 & servos; I always have to drop down the power on the air radio to around 20. I'll try the toroid as suggested!"

"HI Ivan,

Many things can cause this, usually interference from other devices on your copter. Check for any new equipment you may have installed (BEC's, VTX's etc), and start unplugging them until you find a cause. Good luck!"

"@iskess thank you that's the exact airspeed sensor I have right now (bought from 3DR). I'll order a replacement one from rctimer to test out. very weird though, today I could not make the AS jump again by putting my finger over the pitot. must be…"

"if I cover the hole on the end of the pitot with my finger the airspeed value jumps to 30, not sure if that's normal. "

"Hi Mark,
I also keep a foam cover over the pitot tube when powering up - but as iskess mentioned i guess it doesn't make a difference as the calibration has to be done manually anyways?"

"I tried to run the preflight calibration, and I cannot get the airspeed value to be less than 2.8. It is fluctuating between 2.8-4.2 while sitting on the ground. Could it be a faulty airspeed sensor? "

"hi iskess,
I did not perform a preflight calibration - on the field I'm using a tablet for telemetry; im not aware of a way to do this calibration with the android app (haven't found it).. the wiki only gives instructions for mission planner.

"Hi Scott,

Thank you for your input. Are you aware of a good way to check if the airspeed sensor is badly tuned? I ran through the calibration as directed; on the ground it shows a value of 3-4, and if I blow on the tube it does increase..

I…"
