You will get bored of the 4star real quick unless you build it with all the mods. Then you will just try and get it to fly like the Somethin Extra but eventually you will just build the Somethin Extra. So, build the Somethin Extra first [:-]

I have built and flown both of these planes. The Something Extra is a friendlier build and setup right, low throws balanced a bit nose heavy would be a much better choice.
Here are the ones I built. I turned the canopy around, took out some dihedral, removed an entire cell from the outer wing, both sides to get it to roll faster, installed a Smith Mini Cowl and a Saito .91 etc etc. The SSE out performed it stock !


Can you tell I like the SSE
