Looking at photos available of the GP Extra on the various forums and that of the SSE, the SSE seems to have a thicker airfoil and larger strip ailerons. Since the hinge line of the aileron is thicker, there is definately scope to make larger ailerons that will give more throw for 3D. I read through some of the myriad build threads and there seems to be a need to enlarge the rudder by 1" and the elevators by 1" to get more 3D control ability. This airplane seems to be more like the Twist than the GP Extra which seems to be more scale. However, it is 40 size and I am looking for 60 size.

What I like in the SSE is that it does not have the LG mounted in the wings. I noticed on my Phoenix Tiger 40 and my US40+ that is is impossible to keep the wing mounted slotted LG blocks from breaking if you have a hard landing or on our post-monsoon fields where landing in the tall grass is the recommended as compared on to the sandtrack or in the water on our horse-racing track. I know that there are some issues with the stock LG as well. I am sure that this airplane will be able to handle a 91 4 C as it is not more power than the 65 sized engines. Also I have a couple of 55s lying around

Any suggestions?
