im looking to strip and scale out a small eflite aeronca champ doing a full cockpit where can I get a full civ pilot from?

Find the wingspan of the full sized Champ. Convert it to inches, and divide it into the inch wingspan of your model. This will provide you with the percentage, ie, 25%- 1/4 scale, 20% = 1/5.

pilot scales are figured on a 6' (72") norm, making a 1/6 scale pilot =12"

You can do the math.
