RE: upgrading to ailerons
I myself am a huge fan of GWS mainly cause of expense. Very in-expensive planes, not the greatest construction in the world, but hey you DO get what you pay for, and with simple added steps and pre-cautions the GWS planes are phenominal!
I would recommend a E-Starter to you for your first Aileron plane. BUT if you MUST chose a warbird for a first one the Corsair the the mildest of them all!
