Enrique,

I already tried this e-mail last week and didn’t get any answer.

Roberto told me about Bernie. I will give him a call this week.

Thanks

Ruiz,

At the 180 I tried other thermocouple, but the problem persists. I will check the ECU wiring, probably it is a wiring problem.

The 280 engine developed problems with bearings now… after it almost melt itself.
The fuel mixture in this engine is so wrong, that the stainless steel hull is becoming to be blue near the spark plug. I thought it was lean fuel mixture… but no, it look like an afterburner turned on.

Jan ,

My 280s are from Netherlands. They are old but they work great.
The 180s are quite new, I bought them in 2002.
The problem is get in contact with this people… I think I’m being ignored! I would love an engine upgrade!

RE: AMT USA
 

Nah, it´s just your imagination.. ;) Give Bennie a call, or you can just ship the turbines to AMT Netherlands. He will repair and upgrade your engines without any issues.

Plautos,
Go your pm this morning. I should have answered all your questions. If there is anything further that you need help with, please let me know. I do not get on RCU much, so please contact me at the below.

RE: AMT USA
 

Hi guys I was wondering if any of you can offer me some advice before I speak to AMT heres my problem . . .

I started my Air start Mercury turbine started it today as normal with no problems and then after use used the ASU to run the cool down as normal. On the second start some 45 minutes later the turbine failed to start. All the transmitter calibration was completed successfully as normal and the air pressure and gas pressures were good, they were connected as normal, the ESC was put into start mode as normal using the 3 position switch and the sequence began as normal however the air supply delivered to the turbine via the ASU unit was constant as apposed to sequenced bursts, the turbine failed to start.

There were no error beeps during the start procedure? (it has the first generation ECU as pere picture at the start of the thread)

I checked the battery for the ECU and also the leads and wires connecting the glow plug / RPM sensor etc an all was fine, nothing had changed from the previous start up / shutdown procedure.

Please can you offer me some trouble shooting advice?

Scott :-(

I don't have the ASU start box, I start mine manually. Glow on, spool w/ air, come off the air, introduce propane as it spools down, as soon as it lights, air full on, glow off, and away she goes !! Follow the commands of the EDT read-out, and it works great. I use that method on my Mercurys, and Pegusus's. Just don't let the RPM spool too low when introducing the propane, or you will get the loud "POP"...

Good luck,

Danno

RE: AMT USA
 

Danny sounds good . . . I dont have the GSU or EDT so will be unable to manual start - the turbine is enclosed on an F15 so the ASU plug in the front is convenient . . . can you think of what I can check next? The glow plug is good, does the ECU check that the RPM sensor is functional or just wait for a vlaue to be returned? I was wondering if the RPM sensor could have gone faulty and the rpm info is not being relayed to the ECU / ASU and this is why the ASU does not come off the air? I am confused . . . :-(

Thanks . . .

Scott.

RE: AMT USA
 

No way to know RPM w/out a EDT... Those speed sensors are known to go bad, however you don't need RPM Measurement to fire on propane.. ( You don't even have to have the ECU, Radio, or anything turned on to light it off on propane. ) Air, Propane and Glow is all you need. The ECU measures temp, rpm, etc, to ramp the Kerosene. I know that Propane pressure can will affect starts, especially when it's cold out. Try a fresh bottle, and I've had to shake them during start-up to get enough pressure on colder days. More so w/ the Pegusus's.. The glow plug reading could be fooling you too. Make sure the element coils are pull out good and you get a bright illumination when testing it. Thats about all I can think of.... Air, Fuel, and Fire... It should go !!!

Keep me posted. !!!

Scott:

The constant air could mean your RPM sensor either went bad or you have a bad connection, when in the start sequence, once the air spools the turbine and the RPM reach about 4k RPM, the GSU will shut down the air supply until RPM goes down to about 2k this will happen until the gas is lit and a temp rise of 50 degrees (I could be wrong on the exact amount) takes place, if the air supply remained constant I can only assume the ECU is not getting a reading therefore the air supply does not get shut off. When the start-up RPM (4k) is reached, the ECU beeps, check for the beep when the spool up happens, if the ECU does not beep, you have a bad RPM sensor or sensor connection.

RE: AMT USA
 

Sounds like an rpm sensor to me. If it were the plug, you will get immediate error beeps. If the air continues to spool the engine, it's not reading rpm. Check the connection for the rpm sensor first but it sounds like it's bad to me. An EDT would help..

RE: AMT USA
 

I had the exact same thing happen to my Pegasus, it was the RPM sensor, I got lucky though, mine was just a bad wire connection to the sensor itself I found this out by wiggling it. Once I got it working I pulled the casing back, resoldered where the wire was damaged and it's been fine since then.
