I have an old 3DR origional IRIS.
The old FRSKY TX is dead, so I waned to repace it with a TBS Crossfire.
Does someone have a working parameter set that supports the ESC, safety switch etc… on an original IRIS with the camera gimbal?
I updated to the latest firmware, but setup under mission planner is still kind of weird.
For instance the drop down boxes for all the flight modes are blank?
Any advice would be welcome.
Hi @pbreed,
I still fly my IRIS fairly regularly. The most difficult thing about the setup is really the ATC parameters which control the vehicle tuning.
We have an old parameter file here that looks ok. I have more if you need them.
Motor output mapping?
And stupid newbe question how do I use the parameter file to do all the settings in it at once?
The standard motor mapping should work these are defaulted using the FRAME_CLASS and FRAME_TYPE parameters
I’m flying an IRIS+ here, completely rebuilt. The latest 'Copter release flies pretty well after updating some parameters that IRIS required. It tuned up well and if you’re willing to do the work you should be happy.
I should add that I ‘merged’ the IRIS+ parameters from the config page, right side, with the latest 'Copter, maintaining my changes. With only the throttle notch tuning done (after a full setup) it still flew, but was twitchy. A look at the rates verified the issues.
HOWEVER, @rmackay9 , I would be very interested in your additional IRIS+ params. I’ve put in a lot of time on the bird and have no problem experimenting.
…I should add that the developers here have greatly helped my efforts to get an old bird flying. Thanks, guys!
Its all working!
Thanks! (New M9N GPS works way better than the old one)
Good on you, Paul. So it is flying? What did you end up using for firmware?
The latest 4.2 mainline releease.
TBS crossfire in PPM mode.
Matek M9N GPS.
Old 3DR SIK radios…
Really slow…
The following was a full auto mission around my neightbor hood with me running after it to keep in LOS.
Paul, all good! Did you have to change many parameters to get basic functionality?
What are you using for your controller with Crossfire?
No the defaults all seemed to match the parameters that rmackay9 posted.
I’m using a tx16s with EdgeTx as the controller. I had to map some switches and do a bit of adjustment on the 6 posiiton switch to get all the modes…
I have
Manual
Stabilize
Loiter,
Autotune (did not need this)
Return to land and
auto
On the s positions of the 6 pos switch. To make this work I had to set gain to 75% and add some offset…
All good! Many of the parameters were originally developed for IRIS+ , I understand.
I’m looking at those now.
