Question
What's the largest UAV you built?

Hi

What's the largest UAV you built?
And how heavy is your non-flight essential gear, if any used?

I'm working on a pano pan&tilt for a 2.5-3kg cam&lens (initially to be mounted on a blimp) so would be nice to hear if you flew with that load of photo/video gear.

The current thread for the tilt assembly is at Builders Workshop, and it's a bit raw at the moment.

PS: yes it would be quite dangerous to put up decent dslr and lens on an ordinary model, but it's not a much higher risk, compared to flying those pimped UAVs with expensive electronics and passion put into them.

That's a bit less than half a kilo for gear, right?
Very good, given the size of the model.

Yes, or 454 grams to be exact.... Not that I have estimated payload that accurately...

The Tyro 150 i very light and yet strong so with an extra pound it still flies comfortably.

We've got a senior telemaster (8' wingspan) that we use to test-fly our equipment.... To date we've loaded it up with a 500 MHz single board computer, two cameras, a wifi connection to the ground, GPS, and some other random stuff. Soon we'll be adding a pitot-static system and 3-axis information (angle roll rate sensors and linear accelerometers)....

Once all that stuff is ready, it's being put onboard our 58" scratchbuilt UAV.

Blunderbums 144" is carrying 20kg, how did you manage to get 24kg with just 101" wings? is the wing surface huge?

for a while, it had doubts i wont even see a hobby plane to mount a DSLR on, lol

Check out the vintage Guff and Radio Queen designs.... the latter was the first plane to cross the English channel and the first to fly with a huge electric motor and the battery payload was massive for a stick built model and it landed in one piece.

Sort of Large UAV's

130lb., 12' span UAV's are the largest I have built, the current version
is still a 12' span but has trimmed down to 60lbs. to 65lbs. wet with a 30lb. payload. It is launched by bungee or rail.

M.M.

The wings are fairly thick and have flaperons as well as flaps. Surprisingly enough, the plane floats on landing and is actually enjoyable to fly.
