Thanks for your comments about Evo .46 engine. It came with P51 Mustang PTS alongwith JR XF421EX radio. I asked about radios which is best futaba or JR so I came to know its the matter of your personal preference, normally the first radio you get, u seem to stick with it. Well, my engine cannot start with stick starter I tried best but it needs some good time otherwise with electric starter and the sound and strenght of it is perfect, it didnt need break-in as it came already with break-in. I learned one thing that for next engine of mine I would go for O.S. first otherwise, Saito, Magnum or Thunder Tiger.
Thank you all
