Ian Soler commented on Joshua Ott's blog post Iris details: #1 The 4-1 ESC/Power Module
"You cannot just flash these with BLHELI, without knowing what the ESC's are based on. We can see they are AMTEL. and a USBASP AVR will do the trick. But what file do you select from the BLHELI menu? For that matter what files do you choose from…"

"CLERC, I do not work at 3DR anymore, so I have no idea if this 4in1 is available as spares. I'm sure customer support can help you with that info, however. :)"

"Keeyen, That is some heartbreaking work, my friend. Slightly off topic: do you have any 'before' data? It would be interesting to put a different time scale on this information -- building a timelapse video showing this spread across…"

Forrest Frantz commented on Joshua Ott's blog post Iris details: #1 The 4-1 ESC/Power Module
"Thanks.  That just saved another 2.265 grams (cut off most of the red/black small wire since the ship doesn't have a gimbal yet; did save a little wire stub for when one is added).  That reduces the final weight to 6.3 grams per ESC,…"

"Forrest, The parallel power wires are most likely for powering a gimbal. Sounds like the ESCs should stay cool in your setup."

Forrest Frantz commented on Joshua Ott's blog post Iris details: #1 The 4-1 ESC/Power Module
"That was fast! Voltage says it's parallel to the batteries, which I didn't expect. Naked meant removing the: - heat sink (18.8 gram savings) - heat sink glue  - large power wires and XT60 connector (only need 16 AWG w/ 2mm bullets…"

"Forrest, The small red/black circuit is most likely for gimbal power, is it parallel to the battery inputs or 5v? On question 2&3: Yes, Pixhawk Main Out 'S'(1-4) connect to 4-1 Pwm In, and ground wire connects between Pix Main Out…"

"IRIS 4-in-1 ESC Quick Look Just received one.  Hope to highlight it + the Pixhawk on the multi-copter targeted to break the world duration record. For those that are curious, the naked weight is only 37.9 grams.  That's 6.8 grams per…"

Joshua Ott replied to Pedals2Paddles's discussion Gimbal for GoPro inside waterproof case?
"Tamas, Just to be clear, I have no intention of trying to sell this gimbal on its own, as it is quite specific for my airframe. I merely wanted to chime in on this thread and support the idea that using the waterproof GoPro housing as part of a…"
