Going back to your first post I have to ask the obvious question: What is your R/C flight experience? Are you 100% proficient flying small high performance aircraft with high wing loading? If not then the P-51 is absolutely the worst choice you could make for your next plane. The Mustang is pretty but it's also pretty bad as a plane to try to fly before you're ready for it. Don't use heavy stuff just because you have it or because you can get it cheap. Get what you NEED to ensure a flight rather than a crash. This ain't a trainer and it will bite you in the a$$ at every chance. Don't give it any chances.
