I'm sure this has been so sorry for repeating questions, But I am looking to put a bigger motor in my Hanger p-51. I'v had mine since they very first came out and the motor after hundreds of flights is getting to the end. And I'd like to get a motor that is bigger. I'd like to stay with Evo motors since I had such good luck with the stock one. Looks like my options are a .52 or .61 so if someone could tell me which would work best and what I may have to do to install it that would be great. I'd rather put in the .61 so if someone has done this please tell me what you all got and did to get it to fit.

Thanks guys,
