"Unfortunately the requirements for for forward flight and hovering a very different. For forward flight the thrust needed equals to the the drag of the airframe, which is a lot less then the thrust needed for hovering. It is very inefficient to use…"
"@earthpatrol, you definitely don't want to leave a naked carbon fibre composite just stting in the sun for a long time. The temperature of the part can easily reach over 100 deg C.
During flight the airflow should be enough to cool the airframe."
"The failure rate for electronics is high is high at first, then goes down and then goes up again in time.
So, if the flight controller has not failed in the first few months of use you shouldn't have anything to worry about for many years to come.
"1. The project is doable.
2. I would suggest using a plane. 50- 200 km^2 is going to take a really long time with a multicopter, especially in the mountains. pix4d is totally ok.
3. You can get away not ground control points if you use an RTK GPS+IM…"
"Usually the volume coefficients are used as an input not some percentages of the wing area. There coefficients you arrived seem ok to me, but they really depend upon how you would like the plane to behave. There's an article in the RC Soaring Digest…"
"Increasing the ISO is not a very good idea. The sensor is small as it is. Cranking the ISO will make the images very noisy. Your experience only reinforces my point that the camera is not suitable for aerial photography except when you have a vibrat…"
"Rob had definitely got a point here. Looking at the POD artwork, it seems that the wings have a bit of forward sweep which would move the stable CG region forward compared to an unswept wing. If the wing had >=15 deg of backwards sweep then the curr…"
"@Randy, the linked product only extends the ribbon cable using an HDMi cable.
Shielding the cable should help a bit. Some RC action cameras using ribbon cables have also had problems with interference. Shielding the cable with copper or aluminium ta…"
