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.

Vector P (designed and built the proto and molds for the original Vector P UAV.)

101" and 55 pounds wet. Great flying plane IMHO.

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.

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.
