Eagle Tree Systems is pleased to announce the availability of the Seagull Pro Jet Wireless Telemetry systems. The combination of our Pro telemetry system and our new Jet ECU Interface technology gives the Jet Pilot critical turbine and other data in real time.
Now you no longer need to guess at whether your turbine has flamed out, whether your battery pack is running low, or whether your airspeed is too low for a safe landing.
Our [link=http://www.eagletreesystems.com/UAV/uav.html]Pro Seagull system with ECU interface cable [/link] connects to your turbine's ECU (via your ECU's telemetry/GSU/data terminal port) and provides the following real-time information on the Wireless Dashboard's LCD screen:
* Turbine Temperature
* Turbine RPM
* ECU Pack Voltage
* Airspeed, Altitude
* ECU Pump Voltage
* Throttle Deflection Percentage
* ECU Status messages
* Other critical data you can use
And best of all, you can program alarms to sound if your turbine flames out (RPM or temperature too low), if your Pack Voltage drops below a preset level, if your airspeed is too slow or high, and much more!
The Seagull Pro Wireless Flight Data base system includes: LCD Dashboard/Receiver, Onboard Black Box and Transmitter, Brass Pitot/Static tube, temperature sensor, RPM sensor with magnets, t-fitting for static airspeed and altitude, 4 Y-cables for servo monitoring, battery backup cable, Windows CD with Virtual Instrument Display and Graphing, and instructions. Many optional modules are also available.
Eagle Tree currently provides ECU interface cables for JetCat, AMT Netherlands, and Gaspar/FADEC ECUs, with others coming soon.

Not bad, however these guys here have developed basically the same thing in a totally homebuilt unit.
Great great great feature: it also includes a fuel-remaining indicator based on amount used :-)

Prototype testing currently under way, they are thinking about making kit units available...if i have telemetry i want to know the really important stuff as well.

Congratulations Bill! I know you been working on this for quite a while.
Will this new system be able to report remaining fuel that the JetCat ECU calculates?

Hi All,
SJN, the max speed is in the low 300's (probably around 330). How fast do you go?
MiniFlyer, we have a proto version of a fuel module that plugs into the above system. Should be ready soon.
Bob, thanks for all your help in getting us to this point! Yes, we will add the fuel remaining feature to the firmware for JetCat. That's very easy to do.

Bill, how do you measure fuel?
These guys are using a fuel meter that measures the flow.
I for myself am not all too happy with the thought of having something in the fuel line that can clog up up jam...
A pure voltage "calculator" is not a good solution in my eyes either, because it does not take the fuel system pressure in account (high pressure will lead to high voltage even though there is very little fuel flow)....not critical when uses in a series production turbine, but it will always only work for this manufacturer...me as a homebuilder with different fuel pressures in the various turbines cannot get very far with such a system.
How do you go about measuring the fuel quantity?

Hi All,
Miniflyer, we will release more details on the fuel module when we are closer to ship. Please stay tuned!
Mike, do you know the ECU manufacturers of those two turbines? The Wren's website has zero info, and I couldn't determine whether Artes manufactures their own ECUs or uses a 3rd party.
If we do not support them already, we can relatively easily add support, if there is interest.

Hi Bill,
I am not sure who makes their ECU units. Artes and Wren are two popular turbine makers. They all use the same terminal display screen with a phone jack plug in. I think you can read the data off that. Are you able to contact these manufacturers and see if they can work with you on this? This will increase your sales. I want to buy an eagle tree data logger if I am sure that it can read my artes and wren's engine info.

Sir's, I believe the FADAC unit is the same for Artes, Merlin and Wren, made by Jets-Munt SL. Eagle-Tree has available a FADAC interface that I assume would work with all mentioned. Bill any input on your FADAC option? WHMC

ya, thats great if i spent time watching that thing my jet would be a smoldering hole in the earth, i think a pocket pc gsu via bluetooth is a much more useable feature , as many people will be carrying windows mobile based smartphones/ pocket pc in the near future. like i said before one less item to buy, and take to the field with you, not to mention wireless! im talking propietery gsu software that gives you full function of the specific manufacturers ecu, obviously the software would be manufacturer specific. jetcat allready having a full function rs 232 interface, are probably closer than they think to being able to do this!

Hi All,
WHMC, yes the Gaspar FADEC is fully supported, so if Artes and Wren use the FADEC, we should be all set with them. We have the Merlin in-house.
techjet1, thanks for the feedback. Our system is definitely not for the pilot to watch during flight. The alarms are audible - you program alarms for low battery, low temp/RPM (for flameout detection), stall speed, altitude ceiling, etc. The LCD display is great if you have a wingman during flight, and for run-up - the unit displays basically the same status messages the GSU/EDT displays, which can be helpful.
Note that we interface directly with each ECU, so the support is customized for each ECU.

Bill,
I have a Jet Cat speed limiter which plugs into the ECU. Will the Seagull system with ECU interface transmit the airspeed readout from the ECU speed inputs from the speed limiter Or will it transmit the airspeed from the pitot static system connected to the Eagle Tree Seagull System?
I want to keep the ECU airspeed inputs from the speed limiter as well as get a readout and audible airspeed tones without using two pitot tubes or putting a Y in the pitot pressure and static tubes if at all possible.
Thanks,
Bob Radford

Hi Bob,
Yes, we can do that. However, there may be some advantages to using "t" fittings with the existing pitot/static lines:
1) the airspeed on the Pro is very high resolution - I don't know what the res is on the jetcat airspeed (it could be just as high). However, it's important to have high resolution for good low speed measurement.
2) the sample rate on the Pro sensor may be higher, and it has sophisticated temp and other compensation (again, the jetcat airspeed may well be just as good, as JetCat is an excellent product in general - I don't know)
Also, there is no technical downside to using T fittings that I am aware of, aside from the headache of the additional plumbing.
