Changed the bearings on my SA125 for a few days ago as the stock ones had a bit radial endplay when moving prop.tips back and forward. Now this engine is turning a APC 16x6 @8500rpm great
, same as OS120III with pump both running on 10% nitro and 20% oil castor/syntetic blend.
I realize you are only using 10%, but has your RPMs on the APC 16x6 improved any?
