Jetcat P-80 Temperature problem
Hi:
After reinstalling my P-80 turbine on my F-16 after a minor landing gear supports repair at her second flight, I tried to test my turbine and a Temp error reading is displaying on the GSU that read -E- and 109°C blinking.
The green LED is also blinking. If I move the temp sensor that is over the turbine body and sometimes the green LED stop blinking but the temp reading is still -E- and 109. When green LED stop blinking, and I hit the auto start switch, the I/O board LEDs start the starting sequence and the turbine start to spin but it stops and a Temp error is displayed on the GSU.
I loosed the allen screw that hold the temp sensor to the phone jack board and I noted that the temp probe can be pulled out from the heat shrink protection.
I removed the heat shrink and I found that both wires that come out from the temperature sensor to the board, are broken.
Can I resolder it? Or do I need to get a new one? Turbine has less than 2 hours after serviced at Jet Cat in late 2008 after a jet crash. Turbine was new at this time (first flight). I don´t know if the temp. sensor was serviced at this time, but this turbine has only 2 flights after serviced (Total of 3 flight since new), so I don't understand why temp. proble wires are broken.

RE: Jetcat P-80 Temperature problem
Hi Guillermo,
I answered this in the main formum, sorry for the late reply.
IIRC, this is the same proble as used on everything but the P-60 and P-180/200.
They can break in shipping, or from just wear and tear, I have gone without breaking one for hundreds upon hundreds of runs so it is not something that gets normal periodic replacement like a bearing.
Let me know if you need one expedited and I will bug Bob for you.

RE: Jetcat P-80 Temperature problem
Thanks Matt
I read your post on the main forum
I already ordered one from BVM
Hope I will receive it next week. I live outside USA.
I think the problem is because the sensor rod is bent frequently when installing or removing the turbine from the model. I think that if the rod is fixed to the board with lets say hot melt silicone, when the rod is bent, it do not subjet to tension the wires. Or the rod can be fixed to the turbine body with some type of insulating support.
Just my 2c
