I'm looking at options to convert a glider for turbine use.

Having never done this before, is there a guide for size/weight verses power required? I have a model in mind but think it will be too heavy for my Kolibri.

With regard to Kolibri suitable gliders, I know about the Opus but that looks a little bit mental for me. I want something smooth and aerobatic but not necessarily ballistic? Does anyone have any suggestions? There looks to be a couple of cheapish models around (Jamara?) but I'm guessing I'll need to look at something full composite to ensure the wings are strong enough for turbine use.

Any advice/recommendations greatly appreciated.
