there are two types of warbirds the arf type which are sort of scale then there is the true scale warbird.the arf type are basiccally set up for the average flyer but do require experience as they are prone to snap roll if lifted from the ground before sufficient flying speed is reached,they also will turn left immediatelty if you slam the throttle to full on a take off roll.the difference between a trainer and a warbird is not the position of the wing a trainer is designed to recover from your mistakes a warbird does not allow much room to mahe a mistake.the wing loading is higher and you must use rudder to recover from snap rolls at low flying speed as using airlerons will make things worse in a hurry.then the scale warbirds have even a higher wing loading and require more expeerience,check out the warbirds forum for snap rolls and see how many new warbird pilots had problems on the first take off with out any idea why.take that trainer you have and add weight at the cg till your wing loading is 25 oz/sq ft this is a low wing loading for a warbird but you will see a big difference in how your trainer fly's
