I would recommend a Simple Storch converted to a trike for a couple reasons....
1) Bigger flies better. Generally speaking in RC, a larger wingspan and greater weight (while keeping to good wing loading ratio) makes the aircraft more resistant to wind buffeting and generally respond a little slower to control inputs - making it easier to fly and learn on.
2) That leopard motor in the mail to you should take a Storch from "casual confident performance" to "nearly unlimited vertical" - but it would be silly large on the Simple Cub - unnecessary weight and torque roll pressure.
3) The Storch looks fabulous done up in a military paint scheme - either axis or nordic
4) Trikes are much easier to takeoff and land - and you'll break a lot fewer props with that wheel keeping the nose out of the dirt.
Once you do start on the Storch however, make sure to beef up the spar at the wing join - these planes are known to have the wings clap when pulling out of a loop when built to the original plans. Paint stirrers or the like can work great for this.
