None of the above.

A gas plane would be a big investment for a second plane as the smallest current and common gas engine is 20cc (about 1.20 c.i.) and needs a 9 or 10 lb model. Something that uses glow fuel in the .40 to .60 size would be better. Shoulder wing is easier to work on at the field: a Stik or maybe the Kangke S/K-50 for an ARF. In the low wings the Sig FourStar or Goldberg Tiger series are excellent.
