140RX Blades Rubbing After Service
Hi,
I recently had my 140RX serviced with the bearings replaced by Jetcat. After getting the turbine back, I turned the impeller by hand and found that the blades are slightly rubbing. I had advice from Intairco that as long as the engine temperatures were normal when running that it should be ok. I ran the turbine up at home and all temperature and rpm parameters seem to be normal. I have since had 5 flights with no issues, but upon starting I am still getting a noticeable metal on metal rubbing sound. Is this something that will go away or should I send the turbine back to be checked out? I am a bit worried that the fan blades could get out of balance and do some serious damage at full rpm.
Regards
Greg
