  any body have an iris that switched over to the DIY frame?

  ive been wanting to do this for a while but wasnt sure if it would improve performance.

  Here is a new motor mount for the "Frog" drone project

  Jimmy O,

  I received the picatinny Iris+ motor wire hold down clips you sent. They snap on easier than the originals.  Good stuff!

  Oh, one thing I neglected to add on the drawing... in addition to the the index pins there needs to be some screws or other fasteners holding the cap to the motor mount cup.  Probably several ways to do that...

  Jimmy,

  As long as you are designing arms for Iris consider the modifications in the pic below.  This would greatly simplify changing out broken arms since you wouldn't have to unsolder the ESC and LED wires.  Sorry for the rough drawing... I don't have any decent software for that and had to make do with MS Office.

  Spent a few months designing this mod for the Iris+ after meeting with the Berkeley team and seeing the Solo up close. Arms are no fun to design. I attempted to reduce weight and remove things from the FOV for video. There are many tweaks ahead but I am pleased that I can build modular solutions for this platform.

  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.
