I am unable to find exact information about servo tolerance.
For example very popular Futaba 3001 tend to have a lot of loose because ot the gear precision, yet when they run all is ok (besides that they are slow).
On the other hand Hitec HS-425 appears to me to have null loose.
Hitec HS-225 have little loose and is very fast servo, but in order to hold its position requires huge power.
Most digital servos tend to be either slow and fast, but have…Continue
In response to Chris' post of the best AP video ever, I have this offering
Just AV FPV, not UAV, but brilliantly done.

I would like to share with you my last video in Évora.

As a participant in the Harvard University Robobees Project, our primary task at Centeye is to develop a vision sensor system that will fit into a small flying robot about 2cm in size. The target weight budget for the vision system is 25 milligrams. While we still have a ways to go before achieving this, we…Continue
Because of the limited flash space of Atmega16, the code of OSD is slightly changed, and it is not compatible with Michael's original config tool.…Continue
Recently I have joined this community. However, I am not working on building a UAV but a DIY autonomous sailing boat. It might not fly but such a boat can use the technology developed for UAVs.
With a lot of help from a good friend I have been able to design a small sailing boot made from PVC, which has no electronics in it, yet. It only sails in one…Continue
Had a little fun flying in a local park here in Johannesburg, South Africa. Used a GoPro Hero on my own design anti-vibration mount and my quad running the newly released v2.5 firmware. Click on the photo to go to the youtube video.

If you are planning a commercial UAS operation down under new proposed guidelines are on the table for simple RPAS flight.
Away from built up areas, within VLOS below 400' and outside of CAS. Much the sort of thing that might come into place in the USA eventually.
Its the first qualification in the civil sector that I know of that is so well defined. Fifteen units to pass.…Continue
Hi Everyone. Above is an intro video to the minimosd. It still needs a tiny bit of tailoring but I figured I would send it out to the community for review. A video series like this could be beneficial for our community to grow in the future. Open to adding on a distributor logo for some help supporting my own hobby/builds.
Of course the video…Continue
The er9x transmitter now will display MavLink data on the LCD.
Gerard Valade a DIYdrones member wrote the software and myself who was the principal debugger.
Works at 19200 and 38400 baud. Still have a problem with 57600 baud. Some kind of timing issue yet.
Here is a pic of the arduplane 2.30 MavLink display on the er9x.
There is an Xbee inside the er9x to…Continue
It has been a crazy week! Thanks so much for all the help testing and great data. Ironed out a lot of bugs and added some new…Continue
here is the last project I'm working on. I'm trying to build myself my own RC transmitter with my android phone (geeksphone zero) as configurator.
I first try to get a working ppm out of my custom IOIO board, but it was not working very well :…Continue

Man I love this thing! Super rock steady and fun to fly. I moved the GoPro to an underside mount facing forward so not to get the props in the shot.
The soldering of PDB was not very difficult thanks to the detailed manual. However, I feel that soldering the Female Dean’s Receptacle first might be convenient as the narrow gauge wires won't came in the path of soldering gun. Though this is not a big issue.…Continue
This week I got a great start on building the Raptor - a 48 inch wingspan flying wing. I learned an enormous amount of information:
1.) 3M 90 Spray foam Melts XPS Foam...
2.) Loctite Foam Board Adhesive Is a great foam, give it plenty of time (24 hours+) to dry/cure
3.) When cutting out flying wings with a hot wire cutter, both sides of the wing (if using a two template method) need to communicate very well
4.) A 12v car…Continue
Some of you may know the history of this site, which began with a project I did back in 2007 with my kids to try to get a Lego Mindstorms robotics kit to fly a plane (it worked). That was part of a series of science/tech projects…Continue
