I highly doubt anyone would be calling TC for someone flying a drone to check on their own roof / eavestroughs.
I'm actually looking for a used DJI drone just to learn a few more things.
Got a better 3d printer than I had previously, and am really enjoying playing around w/ the settings and printing simple things for now. Will get more into the design aspect over the winter (planning to at least).
There've been 3-4 iterations at least of the main sub 250 g DJI drone over the years. Most of the advances have been camera quality, battery life and long distance connection. I have one of the earlier ones and it works fine but people with upgradeitis should be unloading their older ones for fairly cheap. For anyone checking their property and general fun flying those older ones are fine. If you want to send it 3-4kms away regularly you might need longer battery life/better connection ones. I also got this recently Buy DJI Neo - A Palm-Sized Drone for Vlogs - DJI Store which is even smaller but it can automatically recognize and follow you which is awesome. As it’s smaller it’s also more affected by wind though so it’s not as good for general things in poorer weather but honestly, it's pretty amazing kit. I got mine for a lot less on a Prime day deal though so maybe wait if you go that direction.
