RE: build thread on Scat cat
by the looks of the Scat Cat plans it looks quite simular to the Sonic 500 which is available as an arf and cheap, complete with a foam veneer wing plus all fittings inculding the engine mount and fuel tank. also what weight is in a small servo such as a hitec 225 ? you do need a rudder if you intend on doing knife edge type banks as what happens if you have the model in a knife edge and its falling towards the ground at speed ? rather than correct and loose speed by adding opposite aileron you just add some rudder , true.
