"Paint it white?"

"I found a wonderful place to get all the metric bolts and nuts that are hard to find.

Great service, fast shipping, big selection. I needed 4 3mmx6 bolts to mount a motor, ended up getting 50 because the price is right and…"

"I like the idea but it seems that the prop would lag behind it's theoretical ideal position, causing the disk size to decrease, especially under a load. This may be completely unfounded, just a hunch. The slow-mo guys could clear this up.... Maybe…"

"3DR is not amazon! They take their sweet time. If you order from them, patience, patience, patience...I have experience in this regard, order same product elsewhere if possible. My iris+ tipped and flipped a few times upon landing (before I figured…"

"I just powered mine on, then plugged an unpowered charge plug in and it did not shut off. So there doesn't seem to be a battery disconnect in the charge port. Could you check for voltage at the battery pins?"

"David, I would like to use my laptop as well. Where did you get the cable?"

"Would you tell us how it worked out? I am also considering using the Taranis plus for the Iris+."

ps... I did get mine back in the air today :[)"

"Maybe this is the answer! Turn the legs into handles...."

"A switch to stop the motors seems to me to be a no brainer. I had a RTL that cost four blades possibly due to a last minute gps adjustment. In RTL, I didn't have control of the throttle. In my first prop replacement incident, I let the iris+ land…"

"Which ones did you adjust?"

"Awesome video!
Thanks for sharing!"

"I have reset all settings as described by Todd Harper, but the propellers still wont spin up upon arming. Is this a radio issue? How would one reset the radio?"

"I've had mine for a few weeks. A few dozen flights. Two crashes upon landing, I set the throttle all the way down but IRIS vetoes that, flips over, slinging gravel, breaking props...need some sort of kill switch so once it has landed, I can stop the…"
