Hi Bruce,
due a accident of a transmitter module a friends copter crashed while fpv into a bush/wood which makes it really hard to find it. This led me to the idea of finding copters by their LED light at night. But how to get navigated. This led me to some nice videos on IR capturing, for instance in 850nm. And i Wonder why not flying into the dark/night on a field (of ownership). Therefore only a cam without IR filter (review how to remove it), and a IR lenser with enough lumen power should work well.
I would really appreciate a review on IR FPV flying, what do you think?
