hey guys i have a saito 4 stroke .72 and i wanted to put in my new great planes u-can-do 3d .46 but after reading the instruction book it states not to use anything bigger than a .70...i do have a os .46 fx that i could also place in this plane...so my question is which motor would you use and why...i have that .72 in my mustang and i love the sound of that 4 stoker when it flys around..thanks for all the info ahead of time..
