  Thanks, Mike.  I solved my problem.  The repair was fine after all.  Turns out I had dropped the transmitter after the crash and it loosened the connectors for the left stick (throttle and yaw) so Pixhawk just wasn't seeing the signal to even try to arm.  Wasted a lot of time going back to look inside of Iris for issues and it was the darned transmitter.  Murphy's law is still in effect...

  Hi Ray,

  You should be able to arm with your ESC disconnected. The communication between the pixhawk and the esc is pwm which is one directional and gives no feedback. 

  Are you getting any pre-arm messages on your HUD over telemetry? Also, if the pixhawk powers up and your not getting any error messages or beeps, it may be your RC link, the command to arm may not be getting through. Check this in radio settings in mission planner. 

  Hope this helps.

  Regards,

  Mike, so your Iris+ still arms and runs 3 motors with the smoked FETs?  I guess that kills my theory about my problem (see thread above) after similar crash.  For some reason after crash and arm replacement my Pixhawk doesn't seem to be talking to the ESC at all.  Won't even give the failed-to-arm sound or go into ESC cal mode.  Everything on my Iris seems to work... except the propellers.

  Does anyone know what FET is on the IRIS ESC? I have one motor down, looks like 2 FET's up in smoke :( This comes after I soldered a motor lead to the board, I think there may have been excessive heat causing a short maybe. Reading the case I can see Ior p3226 HTZ6_ F8736 but I cannot find this mosfet anywhere? 

  Thanks,

  I  on my 2nd Iris+  and now am having a very hith HDOP when i fly around a tree in an fairly open field. Im looked at the logs and it seems like its droping sats as well. Anyone else have this issue and is there anyway to boost the pull of the gps! Like getting a-Ublox NEO-M8N GPS Module? Would this even work with the Iris and has anyone attempted to swap out the gps module with one and tested it?  I get near a tree and it goes all over the place. The only way i can control it is by switching to stb mode.  I need to fly near trees and some 3 story buildings and it doesnt seem to like doing it.  Any advice is appreciated.  Thanks

  Thank you Phelps!

  Damir,

  You want to check that the LED in leg is still working before you put it all together again.  When an arm is broken it can stress the LED cable.  If it needs replacing, you want to do that when you are replacing the arm.  It definitely requires soldering skills.  You can buy new LEDs at SUPERBRIGHTLEDS.COM.
