well .. next up is adding more to the mix .. full flight controls and perhaps flaps .. several great planes to choose from
that work in this category as excellent advanced trainer types ..I useda thrash on a foam Cessna Cardinal at this stage ..slightly overpowered so takeoffs were short and could get to alt fairly quickly.
I fly 'em till I am completely bored to tears with 'em before movin up .. the one I built after the Cessna was a 60 powered Sureflite Foam Spitfire,
..flew that one for over 2 years ..it was massively overpowered and I basically just wore it out
Got to the point where it was more 'glas and epoxy than foam, weight almost doubled from initial flight from all the repairs .. LOL.
Little things like elevator seperating on high speed dive, flaps out of sync, engine quit on takeoff, ..and just plain screwing up at low alt a few times

Fun plane to fly tho .. I never got tired of it .. got offered more than I thought it was worth after thrashing it
