Don't listen to these guys! Buy the plane, part it out and get a stick!

Now on the humorus side, jump on that deal, leave it as is and hang it on the ceiling until you are ready for it. I would leave the engine because thats me, Mr Overpower everything I have. The plane can handle it but it will be a handful. Make sure that this nice combo is not the first warbird you fly because they are different. If you get a chance to buy some "piece" that is flyable for $20, jump on that too and get the feel of it.
