We managed to get out and do a little more testing. In particular I wanted to test the operation of the PG20 dual battery board. Everything went well, the batteries installed were a Gens Ace 2200mAh 6S 45C pack and a Titan Power 10500mAh 6S 3C Li-Ion pack. The 2200 gives a hover time of 3 minutes max at ~40A.
The plane took off on the 2200mAh LiPo pack with a voltage during the take off of around 21.5V (lower than expected but then current was about 40A) then changed to the 10500mAh LiIo pack with the voltage around 23V.
The area flown was 27Ha (66 acre) with 3954mAh used from the 10500mAh pack so about 44% of the usable capacity. A full pack should thus be able to do 60Ha (~150 acre), not as much as hoped. Time in air was 21m36s with around 50mins expected on the full pack. Again not as much as I was hoping but we’ll test again to see how much we can actually get. Terrain following was activated for this flight, with an elevation variance of about 50m so the plane climbed 40-50m on each leg and descended again. Current usage will be lower of course if it maintained a steady altitude.
Transition back to VTOL was ok and the plane landed fine. Distance covered was 20.3km (~12mi).
I managed to get some air-to-air video from my Mavic of one of the take-off and landing tests earlier. There is a weird wing wobble/rock present just after transition to forward flight, the cause of which I’m unsure, but it was present each time.
