Tri-copter, maiden flight & question on RLT/LAND flight modes

Hi All,First flight of my Tri-Copter yesterday, its a weird beast based on a Raspberry Pi, PixFalcon, PS3 Gamepad controller and a 3D printed airframe. So far so good & pic attached.My question is regarding RTL/LAND - this first flight stayed very low (2 metres) & close to the takeoff point but when I tried the RTL & LAND modes it tried to first tried to climb which was unexpected.The RTL altitude was set to 'current' and if I've understood correctly the LAND mode should'nt climb…See More

3D printed tricopter - latest version.

Thought I'd share some pics of my latest tricopter, it'll be the 10th version and the second 'flying prototype' (with any luck).The design has come a long way, I suspect its still over target weight but I *really* want to get this thing flying.Its all printed in PLA so it can be made on any printer, even the really…See More

Tricopter tail boom linkage

Posted on June 26, 2017 at 10:41am 0 Comments

Here's a better photo showing the tail boom linkage - basically a pair of printed gears.

This design has fewer parts than a conventional linkage, less things to break so hopefully more reliable.

There's a 2:1 gearing ratio between the servo and the tail boom. The servo moves +/- 60…

Tricopter assembly

Dry assembly to make sure all parts fit, so far so good.

The distance between motors is 450mm so obviously the arms need to be cut down.

A PixFalcon goes on top, the GPS/Compass module will either go directly on top of the PixFalcon or have its own mount at the front of the drone.

Target weight…
