Coyote,

As is usual for piper_chuck, he has tried to explain to you why that plane is not a good 1st plane in a very polite way. I bet I can speak for almost everyone when we say the pics of the build that you posted shows that this is not a troll post. BTW a troll is someone who posts a question or statement with no actual bearing or purpose just to get a rise out of everyone.

Anyway, the build looks wonderful and definitely shows you have the skill to do that part of the hobby. I personally do not own that plane but have seen one fly and they can be a handful for someone that has no experience in higher performance aircraft. Now this is not to say you cannot do it and there are people out there who started on a trainer and very quickly moved onto the second or third plane

For that matter I even trained one of my students last year on my Twist after he did one demo flight on my LT-40. He was a "natural" and maybe you will be also. If you have not done so already, if you can, purchase a simulator and give it a try or even better still, go to a local club if you have one close, and see if someone there will give you a demo flight on a buddy box. Then and only then will you know what you can and cannot do.

And just one more point, I have seen (which includes myself) full scale pilots who think that because they fly large high performance aircraft that this is a peice of cake. Once then get on the sticks, they quickly learn that orientation is a problem and so even decide that it is too hard and quit. Flying full scale is easy in respect that you can feel the plane, models do not give you the true feeling in the seat of your pants. The only thing that transfers to models from full scale is aerodynamics.

In any case, welcome to the hobby and to RCU.

Now as far as answering your original question, try posting it in the kit forum, you may get the answer you originally asked as far as the servos are concerned. When it comes to the engine, the best would be a YS110 or an OS120 Surpass or a Saito 150. Do not let the YS110 number fool you, that engine has gobs of power and puts out more than the OS120. The problem with YS engines is they are so popular and in demand it's hard to find one.
