Globemast in your first post you said that your interest was in a Protech Skystar but in the same post the link you provided was to the Hobbico Nexstar, an entirely different but mainstream trainer popular in the US. This is where the confussion arrises.

I know nothing of the Protech product but in their limited site it only lists it as a three channel airplane which means it will not have ailerons. In the past this was a normal method and most went this route it will work fine in that regard but is not the mainstream method popular today.

In my opinion dealing from sites that have virtually no info on the product you are interested in is problamatical at best.
