"Is it set to spin motors on arming? Have you checked the throttle received from the Rx? Does this also do this in Arco mode, Acro mode ignores many inputs and will arm and operate without checking for HDOP and other things.
Seem odd that loiter will…"

"Most common reasons are hdop and compass disparity. Best way to find the answer is to connect to MP while arming. MP will flick up a brief message as to what the fault is. I suggest no props if using a USB cable.
Hope this is helpful."

"To be completely fair I would appreciate an explanation from either part. Was the information given only for Solo development?
Do GoPro get a royalty from Solo sales? If either is true I will happily retract my question and get on GoPros back."

"Glad you had some success.
Cheers."

"I understand you are likely over this topic but I thought you would like a possible explanation. It is my experience that faster or slower FCs sample rates are effected by resonant frequencies, depending on the closeness of the frequencies to the…"

"Crop dusting aircraft, especially those in the 7 to 25 kg range, constitute a serious safety risk. For mine and crops survey,I foresee the equipment becoming smaller and smaller. Small photographic drones would constitutes very small safety risk.…"

"All this stuff is way over complicated. A GoPro on a gimbal and Helium balloon, two strings for orientation are control. Its got to be better that $1.5K and video full of jello.
Really, all this gear is overkill for selfies."

"Thanks for putting this up, Matthew. I wonder how many people will inform CASA they are taking commercial video with their P4 or Solo. Many people will take this as a free for all. It will create that kind of lunacy you get when there are no rules.…"

"Front left hand motor or ESC failed. Because it was so quick I would expect ESC. Could be a solder join on or connection to it.
Once you have a failure, fly low for a bit and try to observe the problem again. It wont go away magically. If it falls…"

"Should work fine. 1045 props will make little difference but will likely be quieter. Be sure to by a balancer and balance each prop. Check ESCs are compatible with FCs , some just smoke and die, and are only suitable for direct receiver control."

"I would like to say thanks to you guys. MiniOSD is an excellent and cheap OSD system for APM and others. The additions you made are really valuable.
CHEERS."

"Hi Alvan
I have a few mates that fly. All at different levels but all keen.
Anna Bay is mostly clear of controlled air space and sounds like a good place to have a flying get-together. My eMail is hotwire.rctrix@gmail.com.
Cheers."

"Either the data is rubbish or something has conflicted with the com port. Which ever, I would set the FC to defaults and start again.
If you have another PC, it would isolate the issue to the computer or the FC."

"Hobby King TX/Rx systems usually contain a usb plug to fit a GoPro. Some have an intergrated screen. Cost is about US$300 for a 5.8GHZ system.
I don't have a SOLO so I can't tell you if it already includes a Video Tx but these are just about the…"
