As promised ("take one for the team") I bought one of the Feiyu FY-3ZT autopilots from Hooks at, and it arrived today.

I haven't had a chance to test it (the software only runs on Windows XP right now, and I don't have any XP boxes), but here are the unboxing photos:

The instructions don't look too bad for a Chinese product.

Here are the parts:

--The three boxes in the middle are the (top) IMU, (middle) Remote Adapter and (bottom) Autopilot controller. Only the IMU and the Autopilot go in the plane. The Remote Adapter is for the ground station.

--Hooks also threw in a 433mhz 500 mW long range modem (black modules at left). I have no idea if they're legal in the US!

--There is also an OSD module (FY-OSD); I'm not sure if that's part of the basic kit or Hooks just being generous to me again.

--The GPS module is one of those very small Locosys deals (MC-1513). I'm not a huge Locosys fan, but we'll see how this performs.

--And the thing with the two red Deans plugs looks like a power/current monitor.

--All the rest is all the necessary cables, antennas and mounting bits.

Of course I took the boxes apart. Each one has an AMR7 processor. The IMU has the usual 3-axis accelerometer, a 2-axis gyro and a 1-axis yaw gyro. The controller board has a absolute pressure sensor. All the markings on the chips are obscured with black varnish so I don't know what kind they are.

I've got to fly off to Europe again tomorrow (Paris this time), so I won't get a chance to start testing until next week.

All the markings on the chips are obscured with black varnish? why? can the system be cloned knowing this info?

looks quite poor in electronics to be so expensive, let's wait for a test,

Well it's not just electronics! is it?

Hooks, you are a one man army. Well done

Remember there are diffrence between IMU and AHRS.

The key difference between an IMU and an AHRS is the addition of an on-board processing system in an AHRS which provides solved attitude and heading solutions versus and IMU which just delivers sensor data to an additional device that solves the attitude solution.

BTW the OSD is part of a complete system.

The data link comes with 2.4 Ghz 100mW as standard.

Sgt Ric!
I don't belive you want me to comment on this!
This is fare from Yamaha RMaxes tech.

Hooks, could you clarify what's in the $1,195 commercial kit? I know the radio modems I got are not the same as the commercial ones, but is the OSD and current/voltage sensor that I got part of the standard kit?

Comment by Robert Krogh (hooks) on June 30, 2010 at 2:19pm
Yes Chris! you are right sorry for not clarifying.

Standard Commercial kit:
- FY3zt Autopilot
- FY3zt Controller for GS
- GPS 10hz (first version was with Ublox GPS)
- FY data link 2.4 Ghz 100 mW more or less same range as some Radio controler. Manual says up to 4 km but..
- All wire for perfect setup PnP

And yes it's possible to upgrade to a stronger data link and FY-OSD

433 Mhz UHF 500 mW - Same frq as LRS RC controller uses. (HAM licence) 5-7 km optimal over 10 km.
The FY-OSD is also a PnP solution for the AP with some of the same info you have on the GS. The OSD and current sensor is an upgrade for the system, because you have all the same info on the GS software, it's nice to have, but not a must.

BTW a new version of the GS software should be ready in August (compatible with Vista and 7)

@Hooks... did I say something wrong?... I didn't mean to come off as a smart a$$ or anything.

Comment by Robert Krogh (hooks) on June 30, 2010 at 2:51pm
No no it's no problem! It's just that I have to hear about copy shit every day. Belive me this system is not a copy! it has a great story, but would be too long to post.

:-) Dont worry be happy.
