PT20 - CG Location?
We have a new member in our club that inherited a PT-20 from his Dad and the instructions are long gone. Does anyone out there know how far back on the wing the CG is located. We have started by putting it at the spar, but it still had quite a bit of porposing in it. He is flying it with a OS 25 and a 4 oz tank. Not sure you need the engine and tank info, but thought I would throw it in.
