E-flite 450 can handle a 15-25oz 3d plane and a 20 to 30oz scale plane. It should work fine. The propeller recommendation would be a 10x3.8-11x4.7 propeller and the 3 cell 1320 should work fine. Start with the 10x3.8 this will help keep the amp draw down. If you have a watt meter such as the one E-flite makes check your amps to see how many amps you are drawing. If you don't have one fly your airplane for about three minutes and then land to check your battery and other equipment.
