FY DOS autopilot


Here is the thread for the DOS system from Feiyu tech.

Please see this thread for additional information and video's posted in the first three posts... https://www.rcgroups.com/forums/show....php?t=1575919

Some general info

1) DOS is an IMU autopilot (no thermo piles)
2) it has a functioning GCS in windows 7
3) the AP can not retain any waypoints
4) it can RTL, or circle at given location and do "click and fly"
5) it works with xbee pro ttl modems
6) it has NO airspeed sensor however it does increase throttle to keep ground speed
7)
8) it is also very cheap and should work with the Hornet OSD

Who am I?
I do not work for FY.

About me.. I own or have tried the following for fixed wing craft.

1) Ardupilot
2) Atto pilot (never really got the support I wanted and they moved on wanting more money for features I thought were standard)
3) FY-21AP (good but 31AP is waaay better)
4) FY-3ZT (good but more complex)
5) FY-Panda system (replacment for 3ZT and flies excellent)
6) Eagle Tree (excellent but no waypionts or GCS)


Ok I will reserve some first posts then update as required.

Tech FAQ's

WARNING I have just found that if you don't orientate the arrow to the back of the airplane then the compass will not function properly in the OSD or the GCS. I have it facing backward now so that it reads correctly.

My plane flies drunk in a big S and turns 90 degrees to the flight path, overshoots and seems drunk... how do I tune it?

Will it work for multi rotors?
yes, here is a thread dedicated to multi rotors with DOS https://www.rcgroups.com/forums/show....php?t=1873514

where do I buy it?
http://shop.fyetech.com/index.php?cPath=35

There is alternative fair and cheap price for people that are willing to spend less:
http://www.goodluckbuy.com/fy-dos-in...-airplane.html
http://www.hobbyking.com/hobbyking/s...dproduct=31135


can I use my own modem?
yes any standard xbee protocol or 3DR modem will work

does it work with XP?
I don't have any issues personally, if you do let me know and I will post them here

how do I upgrade firmware?
with a downloadable utility inside the zip there is a pdf that explains everything... if you can't read then you can watch this video https://www.rcgroups.com/forums/show...&postcount=661

how cold can it be to fly?
I have flown in 0 deg C with no issues.

will it display my voltages and current on the GCS and the OSD?
yes it works well with the Hornet OSD but will not display voltage and current in the GCS.

Where can I find the latest gcs download?
the latest one is found here http://www.feiyu-tech.com/download-e...d=43&nav_num=6 I have it working on windowns 7. Run AND INSTALL this program as an administrator.

There is a 2D GCS now but I need to make a map (gst and jpg file) for it... where do I get the program?
They now have two programs to make the offline 2D maps, one called mapmaker which I have a how to video below for and one called GScreen but I need to make a video for that.

Why can't I create any offline maps?
You need to select the map area from top left to lower right when defining an area to create a map.

Both will need an older version of Google Earth found here http://www.feiyu-tech.com/download-en.php?id=63

Where do I find other FY downloads like firmware upgrades?
they are found here http://www.feiyu-tech.com/download_list-en.php

A good post on programming the ER9X for a 6 way switch can be found here

Thanks, Steve. Will wait you reports.

I'm try to purchase FY DOS, to replace my FY 21AP.

And still wait AP with air speed sensor from FyeTech.

yes they have told me recently that the airspeed sensor development is now on hold... not sure when it will come to market.

I am looking for a new OSD and autopilot system to put in my super sky surfer. I'm thinking about trying adrupilot 2.5 do you think it's good! Also is there an OSD that works with it so I don't have to have 2 gps's etc. I'm also wondering how good the 31ap is? And how easy is it to setup etc. what's the difference in the 31ap and the DOS?

I think the FY-31 is easy to setup and use, I used it on my 1st RC plane to help me learn to fly, now has 20 waypoints for autonomous navigation which is fun to use.

The DOS (haven't tried it yet, currently on its way) does much the same thing without the waypoint navigation but has circle, return to launch and stabilizer built in, can be hooked up to Hornet OSD from memory.

So is the dos any cheaper? I don't really care about waypoint stuff. I just want something with stabalization return to home and an OSD.

Nearly same price when you include the OSD Hornet.

Dos will have better vibration rejection and there is talk that they will test out multi rotor firmware on it in the future too... so there are some minor differences.

I do recommend the 31AP but we don't have any test data on the DOS just yet.

As for APM... some love it... my opinion is a negative one... however I don't have the latest harware so maybe its ok... but they won't be getting me to buy it anytime soon.

Yeah it's actually cheaper to get the fy31ap with hornet OSD combo.

If it will be able to have multirotor capabilities that will be cool aswell but I'm not sure the $260 for the fy31ap plus OSD is as good as the new APM 2.5. People have made and said promising things about it. I just don't know what to gettttt!
