I also fly Speed 400 pylon racers.  APC 4.75x4.75.  Not a folder.  Works great.

My Parkzone Corsair doesn't have gear, haven't lost a prop on landing yet that I recall.

With a nitro plane you would have set the compression to have a horizontal prop when landing.  With an electric, there is no compression so the prop gets out of the way really nicely when landing.

Ask Mark Rittinger.  You don't need a folder.
