AERODYNAMICALLY, what would the impact be of adding some slight forward sweep to an existing Light Sport sized single place parasol, originally fitted with a Rotax 2-stroke?
The idea is to re-do the wing attach points and the struts and get the center of lift a wee bit further forward to accomodate a heavier 4 - stroke engine installation of comparable thrust.
My recollection is that the forward sweep will tend to make the inner surfaces of the wing stall earlier than the tips. Moving the CL forward will also increase the tail volume a little, not necessarily a bad thing either. What other effects?
Structurally it needs examination of course.
Lead in the tail would be easier; granted.
