Dave:

I have a p180rx that has no sticking issues, so that is not a norm. My kingtech k100g did develop a "ticking" noise when I would spin the compressor around 12 hours. A few hours later the compressor would "stick", it didn't take much force but enough to stop it from a free spin.

The K100g had massive damage I found out after I sent it in. The bearings were bad, the compressor rubbed, the diffuser was rubbed, and the shaft tunnel was shortened from the heat, ruining the bearings. In my case it was caused by DTE light. The engine ran fine and made no noise during the run. A couple more hours of that and who knows.

Also, I just got my P180rx back from jetcat. I asked them to service it and they didn't. I have had sent it two times and hoping they have it fixed now. I'll run it up today but they put an entire 2 minutes of testing on the engine.

I do wonder, if you heat the engine up with a heat gun if the problem goes away.

But given its new I just cant recommend doing anything to it.

I plan to run up my p180rx today lets see if they got it fixed. Not too happy about high hours on it still, I've already wasted $80 sending it to them twice. I wanted it serviced since it will have to back again!



I say this NOT to bash jetcat but to inform you, that its entirely possible they barely tested it.
