Frank,, thank you for the info !!

but if you will, please tell us the correct way to prepare used Liners for new Rings in smaller Glow Engines in the .10 to 120 size,, please include both Chromed Liners and non-Chromed-Steel Liners,,

I see many Modelers replacing Rings without preparing the Liners, mostly model Helicopter pilots, many model Helicopter pilots find themselves replacing Bearings do to rust (because of the High Nitro Fuels) every 2 to 5 gallons, so they replace the Ring when they (we) replace Bearings..


thank you Frank!!
