Os .62
Anyone know if the new OS .62 four stroke will fit in same mounting holes as the old OS .52 ? Are the dimensions the same ? Sizing this is critical for a Legacy Aviation Monocoupe engine upgrade. Thanks guys.

For the 62. Distance between Mounting Hole Centers Same Side: 0.69" (17.5mm)
Distance between Mounting Hole Centers Opposite Side: 1.7" (44mm)
Length between Front Mounting Hole and Drive Washer: 2" (51.3mm)
Width at Mounting Tabs: 2" (51mm)
Crankcase Width Below Mounting Tabs: 1.3" (34.1mm)
Go here to page 26 for the 52 dimensions: I think they're identical.
