Successful Maiden Flight of my Modular Testing Platform

 

The Modular Testing Platform 2 flies! It flies really well!

 

I had a great hand toss takeoff, a rough start as I figured out the control sensitivities and trim, some good cruise around time, and a perfect landing.

 

Any improvements you think I should make? Here is my planned list for the next episode:…

Starting Out

My name is Michael and I am just starting to get into UAV's. I currently work as a human factors psychologist helping design a future user interface for Air Force UAV's (kinda how I got interested). I am a licensed pilot and also fly RC aircraft (when the Kansas wind isn't blowing 30 mph).



My goal in building a UAV is to have a fixed wing aircraft with fpv. I really just want to explore and learn more about this area.



I am about to purchase the Ardupilot Mega and a… Continue

Better log analyzer for APM



I made a program that shows log data in visual way. I can see plane position, altitude, elevator, ailerons etc.

Here are some screenshots from program:

My plane made strange curves during flight. All curves are in the same places. After a very careful check I found an error in APM navigation code. It is now corrected in version 2.21 (In downloads section…

Offer of help with tuning PID loops

Sorry, but I should have made clear that my autopilot design experience relates to fixed wing aircraft so I won't be able to help with rotary airframes.

I should also emphasise that the databse I have relates to PID control only. After a lot of hard work, I have established which stability derivatives the PID gains depend on so that the job for the user becomes one of estimating certain stability derivatives (for which formulae are also available). The PID gains then drop out as…

Plans for an open source RC Transmitter



Another one from Hack-a-day. It's just a concept so far, but the team that's behind it may be competent enough to pull it off. They're using a Kickstarter-like model to raise…

Offer of help with tuning PID loops

I've noticed quite a lot of debate about tuning PID loops. I think I might be able to help since I've got 40 years experience designing autopilots for air vehicle flight control and navigation. I could give general advice on the best ways of using the P, I and D terms for both primary stability and navigation loops. With more info on the application aircraft I could probably come up with suggestions on which gains to use along with trial values



I think a combination of flight trials… Continue

First time at laying fingers on ARDU PILOT MEGA

the package I have been waiting for arrive today. No Idea on what to do. Plan to build Quad that can lift 4kg AUW. Then will move to Y6 setting. here's what I got from U-drones with latest code loaded+GPS+ful telemetry+only no airspeed.

The 'Ugly Man' meets APM/AC2

The 'Ugly Man' is my mongrel, 660mm, 1.5kg, APV/FPV Quad, so named because a good friend gazed upon it and said 'damn, that thing is ugly'.  This triggered an appropriate old song in my easily programmed mind (Ugly Man), and the die was cast. But, beauty really is in the eye of the beholder, right?

The 'Ugly Man' is…

Gyro-Stabilized PTZ Gimbal for UAVs

 

I am an ex-USAF Avionics Sensors guy, and I have always wanted a gyro stabilized laser targeting system. Now that I am all grown up, I'll settle for a gyro stabilized camera.

 

A little looking, and I found some nice UAV equipment.It's a little out of my price range at $10,000 for the day system and $20,000 for the FLIR system. http://store.micropilot.com/category-s/21.htm

Completion of the MTP II

 

 

This week I completed the MTP or Modular Testing Platform II.

 

For electronics, I added the elevator and aileron servos and mounted the motor, esc, and receiver to the airplane without any trouble. (see links below for which one's I used)

 

I also completed my Clark Y airfoil, which was much more difficult and time consuming than my prior K2 airfoil, however I anticipate an improvement in performance. As I used Bluecore (aka Fan…

Aerodynamic efficiency

As everybody is working on ways to improve electronic response I thought it was time I did a little work to see what can be done beyond the electric motor.  Coanda and Bernoullis effect put to good use.
