"Very nice! I've been considering using folding props on my DIY Skywalker quadplane. I'm a bit worried that they won't unfold properly with forward wind and have heard concerns from others. But it would be so convenient not to have to remove the prop…"
"Sorry that this happened. I know what a sick feeling it is to watch all your hard work go totally out of control. If you were flying with a ground station then there will be TLogs available that might help in finding out what went wrong and where it…"
"25C is a bit low for a draw of 46amps regardless of what the maths would indicate. The battery would be getting quite hot and the internal resistance would increase greatly. On a copter that size I'd be using something more in the 60C range. I've ru…"
"The only issue with separate flights for NDVI and RGB is the time involved. The size area you are considering will take some time to cover so doing it twice would be quite a task.
It's been some time since I've used a GoPro and the newer models are…"
"A GoPro is a poor choice for RGB mapping. It's just not what they were designed for. The camera of choice for mapping is/was a Sony A6300. They are light, cost effective and simple to interface to a Pixhawk. You don't need to worry about roll angles…"
"Ag mapping is a fairly advanced use case for a drone. It doesn't sound to me like a DIY solution is what you need. You will be spending a lot of time and money figuring it all out. You might be better off with a total commercial solution such as the…"
"I've built a couple of quadplanes now and the issue of current draw during transition to forward flight seems to be an issue that requires careful planning. In one of my builds I went as far as separating the vertical lift motors off to their own ci…"
"If they are using DJI then a DJI XT camera would have suited their purposes better as it integrates with the flight controller to record the info they are looking for. If for some reason they don't want to use the DJI XT then the Flir Vue Pro Duo wi…"
