"I just wanted to update the thread, I've replaced the props with the HQ Slow Flyer Props (10x4.7) and I haven't since had such a problem. The hover throttle still sits around 65% at sea level but better than 75% it used to be.

If anyone has any…"

"More to report :)
So today was a really hot day here (+- 37 degrees C) so I decided it would be the perfect day to test the batteries (without having access to a proper battery tester).

I ran all four of my batteries (now labelled) for +- 10…"

"Hi Hzl,

Thanks for taking all the time - I have one of those battery testers and a balance charger but it seems to be telling me things are OK on all my batteries ;(
I think it might just be a combination of everything (heat, altitude, weight,…"

"Hi Rob,

Sorry to hassle again, please see attached from exmaps of the flight data - can you point out what you are seeing? I'm probably misinterpreting this but it looks like the voltage + current are 'OK' even at the time it crashed.
Again I'm…"

"Hi hzl,
Yes it is quite warm here - and also at altitude of over 3000ft - which may have some impact on battery performance I guess.

I'll check those props out - thanks!

Cheers"

"Thanks Rob.

I actually 'like' this explanation as its better than unsolvable magic :) I have 4 batteries - so perhaps one of them is faulty. Now to identify which one...

Is there any rudimentary way of testing batteries? Or should I just hover the…"

"No I definitely didn't change the RCTX to Loiter - and even if I did - at the crash site it was so far away from the Drone I don't think it would have mattered (with my standard antennas etc).

After I got back I went through all my settings to see…"

"I armed from RCTX as well as initiated from RCTX (throttle up once armed with mode set to Auto). I only used Tower to upload the mission."

"Apologies, such a n00b for not including those basic details.

It is a 3D Robotics IRIS+ with a Tarot Gimbal + GoPro. I'm using the stock standard included controllers from 3D Robotics with the IRIS+, I'm not 100% sure what they are. 

Basically, I…"

"I've probably flown it about 30 times in total, and I would say on average I fly it about 5-6 minutes."

Hi all,I'm new here and new to droning in general - I'm struggling to understand why my UAV just suddenly landed during a long-ish auto mission. I have disabled the geo-fences, all the fail safes (except GPS) are set to return to land - GPS failsafe…
