Hi All,

I have to say i had two AECU's fry on me and know of two more from a local club that have fried. the AECU in question was an orbit,.... i still use them and have been VERY happy with the AECU's.
This is what happened, using a Wren turbine(full auto start) started the turbine was at idle must of run for at least 2 minute as i set up the camera to look in the hot end went to raise the rpm to 100k and all was fine for another minute or so then the starter motor over heated as it had been touching the spinner, this almost stopped the turbine dead and would of if i had not switched the turbine off.

The second one the starter coupling failed and locked onto the spinner this time i was running a kj66 the turbine must of run for 5 minute the only thing i notice was it was down on power,... and then a big flame out the back.
Landed and had a good look the turbine the starter motor/aecu/coupling had all been damaged and the turbine would not turn over when i got it home and had a look inside the turbine the rear bearing/turbine wheel and ngv were all damaged and all had to be replaced.

At my local club one guy started his turbine as normal and tried to take off a few times but could'nt understand the lack of power and once again the coupling was the problem and also burnt out the ecu he was lucky no turbine damage.

This is what has happened to me not here say but the facts. I do not know if this was the problem with the Wasp as i was not there, We should all wait for the FULL report on the turbine,........... as it may just of been a sticking coupling or a turbine wheel??. so let the experts do there thing .
That is why we SHOULD wait for the fact's

Just my 2 pence.
