Your fanfold version will be a lot stiffer, but the one you have will fly fine if you just 1. add washout to the wingtips (curl the trailing edge at tip up about 1/4" - make sure it's the same amount on each side); 2. add a piece of DS foam to the top of your rudder forward over the vstab to increase rudder height (maybe 2" tall and inline with the stab LE and rudder TE) and 3. break the wing mid span and add 2" of dihedral per side. It'll still want to roll into a dive, so you will need to add some up elevator in the turn to keep the tail down/nose up - it's typical of that genre. Also typical of the light weight undercamber wing is to nose up and climb when power is applied - just compensate with some down elevator.

All my onesheeters are DS foam so far and they use similar techniques and fly just fine.

Don't forget the foamies - scratchbuilt forum higher up on first page of rcg. Tons of help there!
