SKYBORNE commented on Joshua Ott's blog post Iris details: #1 The 4-1 ESC/Power Module
"I'm trying to diagnose the possibility of a bad ESC in this 4 in 1.I'm presently using 3.3 firmware on the Pixhawk and there [THR_MAX] has been replaced with [MOT_THST_MAX]; and I also can't find 'MOT' in the log files. All…"

"I have one of these.And one of the motors occasionally doesn't spool-up with the rest of the motors. I've adjust the THR_MIN up in value and the MOT_SPIN value and updated the unit.I'm wondering if it has something to do with the…"

"After further research, I believe this is the chip. http://www.irf.com/product-info/datasheets/data/irf8736pbf.pdf ; Can any one tell me if this is the only FET? IE does this ESC only use N-FET's or P+N Fets? "

nz.mike.christiansen commented on Joshua Ott's blog post Iris details: #1 The 4-1 ESC/Power Module
"Does anyone know what FET is on this 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…"

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. :)"

Joshua Ott commented on keeyen pang's blog post What a simple orthomosaic and DEM can do
"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."

"Oh ... $142.31 with shipping.  So it costs more, but so do light-weight carbon frames."
