External antenna causing aerodynamic problems on small models?
Going to an internal antenna looks great, but do you think it buys you anything in terms of aerodynamics? On our smaller 1/2As you can easily end up 12" or more of antenna hanging off the back of the plane. At 50 or 60 MPH this has to equate to an ounce or more of drag and it is whipping around in the slipstream. On a 12 -14 ounce plane, and with the force being applied so far behind the CG it seems reasonable that it could be causing a bit of "wiggle" in the tail.
Any thoughts?
