I have done a bit of research on both the RC Universe as well as other websites and believe that I have decided on the SIG MIDSTAR I think this will do me better than the 4* based on the info i colud get from here and the sig website... The recomended engine for this plane is .30-.40 cu in for 2 stroke, i was just wonderin... about engines. I have the engine from my first trainer which is an Evolution Power Trainer system i believe it is a .46 size. I have considered investing in a new engine as the Evolution has not been run in quite some time... I did drain it and put after run oil in it so in theory it should be fine but the damage to the plaine will make it hard if not imposible to test run the engine without first installing it on a new plane. any advice on this, also Would I do better to get an O.S. .40LA or an O.S. .46LA these are the engines i would probably get if i did invest in a new engine, or is the power trainer system, assuming it still works properly sufficent for this plane? is a .46 size engine going to be too much power for this plane, and are there another engine systems that i may be better off with?

Oh and by the way, thanks for the advice from everyone who pitched in about building, it is really appreciated...
