Have engine, need help with choosing airframe


Good day everybody,

I have recently bought second hand nitro engine and as bonus got tiny extra one. It is in the size field I do not have much experience.

So here I am with engine weight ~100g, swinging 6x3 / 5x4 prop.
What size/flying weight aircraft could consider? Would be looking for slow/trainer type model.
I have laying around 90cc tank - would it be aroung right size?

My 1st thought to go for those cheap china ~450mm balsa kits I think is not very good? ~170g power system for such small aircraft would be too much?

Make. model, displacement of the engine would help. Prop sizes you mention suggest a .047 -.051 cu in engine. A fuel tank of 90 cc would probably run that size engine for several hours I would guess Not enough info to even guess at an airframe for that engine.
