I have purchased two Extra's from an estate sale and need advice on setting up the CG and contol surface throws (no manual and I cannont tell who the mfg is).
One powered with a Desert Air 100CC with 104 inch wingspan and fuselage length of 88 inchs. The other is powered with a ys 140L glow with a 76 inch wingspan.
How do I calulate the desired CG?
How do I calculate the appropriate throws on the controls surfaces?
What would be the recommended expo?
My skill level is intermediate.
