First let me say thanks to the knowledgeable folks who answer questions here! You guys help a lot of people out and I appreciate it.

Here is where I am, I am getting good with my Sig Kadet LT-40. I can do all the tricks I know of that the plane can do. I can fly upside-down for as long as I want. I can fly it around at almost stall speeds. Landing is a piece of cake. I am ready for a new plane. I definitely want to stick with the .46 sized plane and maybe even use my OS .46 LA from my Kadet for a while until I feel like upgrading. I have several planes in mind for my next plane like the 4* or the tiger 40 but the plane that I really like is the Sig Somethin' Extra 40 sized ARF.

How much more advanced is the Somethin' Extra over the others I have mentioned?

What other planes would you recommend as a good second plane? So many people at my airfield have a 4* or a Tiger. I want something different.
