RE: THRUST WASHER PULLER
John,
Ask Paul at [link=http://rc-bearings.com]RC-Bearings[/link] about the set that you need.
The price will be 55-70% lower than Boca...
Stainless steel bearings are not necessary, unless you want to:
* Never to run your engine dry at the end of the day... leave it full of fuel.
* Use fuel that contains no Castor oil at all... kill your engine so your model will stay a bit cleaner.
* Never to use any after-run oil...
If you want to do any, or all of these mistakes and run more nitro (forms nitric acid...) and make your bearings live a little longer before they rust (stainless steel is only less susceptible to rust, but it will eventually catch the 'steel cancer' too...), waste your money on stainless.
I never had to replace any bearing due to rust, so I cannot understand why it is so common in these pages.
