Telemetry on Custom Flight Controller

My new project is to create an RC model of the BlackFly PAV.  There are many technical challenges to solve and my plan is to first build a 2 motor / 2 elevon VTOL flying wing.  (I'm writing my own FC code using the STM32 Blue Pill).  I would like to know how to send telemetry data from my FC to my FrSky R-XSR receiver using the Smart Port.  Is this possible?  Is there a C++ library which allows my FC to mimic the various smart sensors?  Or just a generic protocol to send the various telemetry…See More

Changing Direction

Posted on November 13, 2018 at 5:30am 2 Comments

Well, the day finally has come when I am ready to give up on this endeavor. My goal was to build a manned, internal combustion quad copter.  I will not say the project was a failure because I learned so much on my journey, but I just see other avenues which seem more promising.

Of note, from the project I did successfully build a variable pitch,…

Bearingless Rotor - Update

Test Video

I was finally able to perform a test of the new drive test stand.  The previous test stand used a 4-stroke engine and a less rigid test frame.  This test stand consists of a 6.5 HP, 2-stroke DuraForce engine coupled to a V-Belt centrifugal clutch with a…

I continue to develop my "full scale" gas powered, variable pitch quad-copter.

After watching the video below at 

Amazing DIY Projects

I realized (more vividly) how vulnerable a quad is to any fault in the control system.

Then I saw his video…

Bearingless Rotor for Variable Pitch Quadrotor

Posted on March 28, 2017 at 8:12am 3 Comments

This video shows the fabrication of a prototype bearingless rotor hub/blade design.

The rotor diameter is 93 cm (36.6 in) and will operate at 1,410 rpm generating 2,000 g's of acceleration at the rotor tip, and developing 1,600 Lbs of tension in the flexelem rod due to centrifugal force.  The blade (pair) is designed to generate 104 Lbs of lift with a power consumption…
