Neither the Yak or the P-38 are going to be good second planes. No matter "how much" you want to fly them you just aren't going to have the skills developed yet to fly planes like that. As it was said above, walk before you run. Get a 4-star or a Tiger II and fly the covering off of them, and then move up. If you want big then get a 4-star 120 size, it's a great flying plane!!
