I build these out of dollar tree foam or blue dow fanfold for my grandkids and so far they like flying the toon planes . It is a german desighn and pretty easy to build plus the grandkids get a kick out of how slow it flys and looks . Its only rudder and elev so i put the rudder on the ail stick so they can learn to fly ail later . My next plane for all of them is a Kadet SR . The best part of these for me is they cost me 3 bucks plus the servos and motor and with cardboard patterns i can build another one fast. Here is a link to the tiled plans ,videos and construction pictures ,good luck joe http://www.rcgroups.com/forums/showt...0#post22098736
