RE: I would like my Four Star 40 (4*) to be a bit more snappy
A four star is well a ...Four star...Kinda like trying to do 3D with a LT-40.....
I know what you're feeling my second was a 4 Star 60..I put in dual rates..as much as I could get had to back off of aierons though, the travel was so much that they were slower than the elevator and rudder to return to nuetral....
Use the 4 Star to perfect your landings, inverted flight, and as many aerobatic manuvers as you can...plus you learn to taxi with full up elevators as you should with all tail draggers...
