Why do larger motors still turn the same size props as the smaller motors. I thought going from a HL 400 xt turning a 10x4.7 to a eflite 450 I could step up to a bigger prop but I am finding that the 450 turns the same size 10x4.7. I used a APC 11x5.5 E and couldnt tell the difference in verticle. I am a little upset that I spent $65 and the plane flys the same. The 450 weighs 1oz more so it helps with balance as I had the Batt as far forward as possible but I want some extreme verticle. The plane is the HL Extra 330 EP at 15.5oz. I dont have the experiance in electrics yet obviously but I figured stepping up motors is the same in electric as glow. I am using an eflite 20 amp esc and a TP 1320 3 cell. The 450 is not any stronger than my 400xt-explain.
