Turbine cooling issue fixed.


I followed a suggestion from David WS on Facebook and guidance from Keith at Fenderbean RC and fixed the cooling issue. I suspected the rubber O ring was slipping during the cool down. David said he had the same issue and took off the motor and cleaned it up to solve the problem. Keith told me how to do it and it was a simple process.


It requires a small star bit to remove the three starter motor bolts. I made a wood pick from a popsicle stick to avoid nicking the O ring.


I cleaned the O ring and turbine rotor bullet nose nut with alcohol and a cotton swab. This pic shows just what was cleaned off the turbine rotor nut. The inside of the cowl looked clean and dry so I'm not sure where the drips I saw are coming from. Reassembly, install, and test run showed cool down works perfect now. I still have the fuel drip from somewhere.
