  Hey Iris+ Pilots,
  After attempting to get my Iris+ going again after a few years there were several things wrong...the PX4 FC would not calibrate the accels/gyros. Maybe if I had used an old 2015 version of Mission Planner the process might have worked...Upgraded to the latest version of Arducopter: 4.2.1 Copter. After executing the calibrations - everything - the bird flew well; however there was no telemetry back to the controller. Trolled every RC forum, twice, and saw that many IRIS+ owners were experiencing the very same issue - lot's of guessing, fixes for other telemetry systems, but no fix. The bottom line is a single parameter change "fixes" the 3DR telemetry:
  -in the LATEST MP (after selecting and configuring Copter 4.2.1 (2022)), find the parameter SERIAL2_PROTOCOL. Change the "2-Mavlink2" to "3-FrSKY". Telemetry now works.
  
  Another major issue seen multiple times is the inability to "Tilt" a Tarot gimbal using the umbilical provided by the IRIS ... again, after extensive search there is lot's of speculation, but no hard answer. On a STOCK IRIS+, do this:
  - In Setup (MP), go to SERVO OUTPUT, and observe Channel 6, with IRIS+ connected by USB or SIK radio to MP. Fire up the controller, and you should see the green bar PWM indication for CH.6 vary as the Tilt knob is turned. If seen, proceed.
  - In the CH.6 dropdown, select RC Passthru.
  - In a stock IRIS+, gimbal tilt PWM is passed via AUX 1 output on the PX4, also known as Servo9. In order to link the CH.6 PWM to AUX1, do this:
  Again in Full Parameter List, find Parameter SERVO9_PARAMETERS. Replace whatever is there with "56 -RC6in"
  Write parameters to IRIS+
  ---
  All the above assumes the use of the latest Copter firmware for a V (not X or +) frame. At this writing, Copter V4.2.1, as well as the latest version of Mission Planner.
  
  I hope this eases the path for the remaining hardcore IRIS+ pilots who have rediscovered their bird.
  
  Finally, a big Thanks shoutout to the developers of Arducopter, who filled some black holes! You guys rock!
  
  John

  Not flown my Iris Plus for some time.  Just checking it out.  What is the latest firmware everyone is using well?

  At this price($399), I normally would jump in and grab a few. However, knowing where 3DR is heading, I have stocked up enough spare parts to build few more Iris if I have to. Also with the price drop of phantom 3, I kind of moving back to DJI. Therefore I will save the fund and wait for 3DR to unload Solo.

  Good job, Steve.  I picked one up, too.  I have only one other Iris+ so I am one crash away from being grounded.  Good to have backup and spares going forward.
• Steve Foster March 15, 2016 at 4:54am

  Ray, thanks for the tip. I ordered one, and they only showed two left! Now I own 4 Iris+, 2 still sealed in box! Hell of a deal, especially when you consider what just the Pixhawk goes for.
• Ray March 15, 2016 at 3:13am

  Just a heads up...  B&H has a special on remaining Iris+ for $399.  Might not be a bad idea to pick one up for spares if you intend to stay with Iris for awhile.  Parts seem to be getting harder to find.

  Armen, I was kind of forced into a DIY frame when the IRIS got stuck in a tree and while trying to free it plummeted 60ft breaking 2 arms and blowing up a motor. It took some time to get the ESC to fire to the proper motors. I finally got it to hover last night. Next to get a full flight in once it's not 20 below.

  I am trying to add a discovery buzzer to my Iris+, it is a receiver type, I am very new to the hobby. I have done many searches to find out how. I don't understand. how to program the transmitter for the switch I want to use and the receiver channel I have it on. 

  If I could get some help I would be greatly appreciated
