3DLabPrint Stearman PT-17 Motor Shims for CG correction
Description
I Love 3Dlabprint! I Built The Stearman Pt17 And It Needed A Lot Of Forward Cg To Balance The Plane. I Decided To Not Add A Bunch More Weight And Designed A Shim That Did The Job By Shifting The Cg Forward By Allowing The Motor And Battery Weight To Move Forward 20Mm In Conjunction With The Shim Weight I Achieved Balance. I Know If I Left The Motor At 0Mm The Mass Needed In The Nose Would Have Been A Lot More Total. I Tried 5Mm, 10Mm, 15Mm And Finally 20Mm. I Put All Files On For Easy Printing But If You Need To Fine Tune Just Scale The Z Axis Only And Get Exactly What You Need.
