That's because those people don't know how to use flaps correctly. Read the thread on the modified H9 Mustang with flaps: [link]http://www.rcuniverse.com/forum/H9_P%2D51_%2560_with_FLAPS%21%21/m_1141981/tm.htm[/link]

That plane landed much better with less chance of nosing over with flaps deployed. Likewise, all Top Flite .60 size warbirds land easier with flaps. Let's put it this way. You would not be bending your landing gear or ripping out your landing gear blocks if you learn how to use flaps. I also have the WM Spit, and the flaps made a huge difference. Out of hundreds of landings on a grass runway, the plane nosed over only twice. If it's a warbird, then land it like a warbird.
