Futaba 3004s are plenty, they will work just fine. We have 3004s & 3003s in ours. Any stantard size servos will be plenty sufficient for this model, it's just a little booger. You won't need any high-torque/speed servos for this one. You'll be just fine with the equipment you've listed from servos to engine & prop, it will all work very well in this plane. Just take your time when you're setting up your control surfaces & get them as close to perfectly neutral & centered out as you can mechanicly & you won't have much trimming to do if you get it right to start with. The other thing is we mounted the battery & receiver all the way up front along side the fuel tank (you'll see the compartment when you get the model) & she balanced just right like that with no added weight. So go ahead & have a ball with it.
