"I've been wondering if this kind of normalization could be done using a sensor installed on the drone. It could measure incident light hitting the top side of the drone during flight, in different bands. This data could be timestamped and later tied…"

"Mario: yeah sure... I only flew it twice in manual mode so far, and I'm yet trying to improve the catapult launch, which is not, let's say, "repeatable" yet :)  Hopefully I'll have some flight data to share in the next few weeks.
Martin: I was…"

"Thanks! It will be great if you have a chance to test that.
I didn't put the systems in place to measure the X5 cruise speed yet, but yeah, I guess should probably be something around that."

"Mario,
What can you tell us about maximum speed over ground with MAPIR? Do you think it's possible to use it on a flying wing @120m AGL? Based on their website, maximum speed for this altitude is 9m/s, but that's probably close to the stall speed of…"
