Tricopter Build Log part three

DSC_0355

It’s alive! The tricopter went under a few more revisions and prints before finally taking to the air. My old Rev One Quadcopter has been reduced to it’s (over-engineered) frame and nothing more. Its parts (motors, ESCs, batteries, Crius AIO, etc.) have moved on to become this very tricopter.

Currently (in the picture) it is set up to fly FPV sans-GoPro. There is an optional part available to replace the camera pan/tilt servo mount/hole with an alternative “use-what-you-want” vibration-dampened plate.

Keep reading for a couple closeups and highlights of the tricopter.

The frame still needs to be prototyped on my printer, though I have modeled the finished project to get an idea of the size.

The distance between motor-centers is roughly 625mm when the two front 1/2″(12.7mm) wood dowels are cut to 350mm and the tail to 310mm (-40mm). This was necessary to accommodate the inline motor hinge that pivots on the axis of the tail arm. These dimensions, along with other things, are subject to change after the prototype gets printed.

I modified Thingiverse user ennui2342’s tricopter body, based off of David Windestål’s RCExplorer tricopter, to support the stronger, more common 1/2″ wood dowels. Other minor modifications to the body were made as well.  I also loosely based my landing gear/motor mounts off of jphillips’ designs. The shock absorbing bottom plates (optional setups for FPV shown above) are unique to this tricopter.
