Does anyone know if the Moki 2.10 and 1.8 have the same radial mount dimensions? I have a 2.10, and I'm going to use a 1.8 for another plane which I am currently building (don't have the 1.8 yet). I'd use the 2.10 as a pattern for this plane if I knew they have the same mounting circle dimensions...also...are they the same length from mounting surface to prop washer face?
