Ok David and Mark,
My objective is to increase performance if at all possible and most of all to not worry any more about my bearings going bad due to residual moisture or nitro.
I decided to start this new thread because the full comp thread did not address my issue clearly. I recently purchased full ceramic bearings for all my engines. I had a choice of either the ABEC 3 or 5. I went with the 5 because I knew it was a better tolerance and higher quality bearing. After reading the recent post on the full comp bearings I want your guys input as to which way to go with the full ceramics.
Back in the days when I was designing and manufacturing the RC turbines, We ran the full comp hybrids at over 160,000 RPM. In the event of a FOD failure the balls would destroy the races but nothing would happen to the balls. I figured this being the case a set of bearings with both the balls and races in Si3N4 would work great under the high nitro and water environment.
In summary, give me your input and forget the money argument. I want to know if they work as well as I expect and what specks to have them built to. What are the correct tolerances for our use and is their a specification that fits these tolerances so I can order them without having to mess with them.
Either of you can call me at 786-280-1246
Thanks,
Albert
