the four star would be an excellent choice. ugly stick type , sig Kavalier or similar. witha .15 your choices are more limited. you could check ebay or post magazine ads .Butterfly(Dynaflite) Ace used to make something called Alpha 15. which is a trainer but with the smaller size would find it "frisky" Sig had some small planes with foam wings in the trainer /sport class but are discontinued . try e bay.
