So, the affordaplane really isn't a part 103 legal airplane.
At least as per the plans. However, there is some hope. The idea is good. The concept is solid. So lets make it legal.
Dan L suggested we swap to .75" tubing on the tailplane. We'll need to do the math to determine if it will support the aerodynamic loads. He suggests there's an 8lb savings to be found there.
I recommended the replacement of the tail tubing, windshield post tubing, and lower motor mount tubing with 2"x.0.0625 wall tubing. I think there's 19lbs to be saved using that technique. Math will need to be done to determine if the tail will have sufficient torsional rigidity.
The cross bracing on the tail should be .75diameter and you can go with much thinner wall tubing. There's 1.6lbs to be saved there, if you retain the same wall thickness.
I suggested that by going to V wing support struts, you can eliminate one 1" aluminum bar, and save two pounds. and the front strut, if bolted in properly, could have it's center 1' removed. Saving three pounds total.
The landing gear as designed leaves a lot to be desired. We'll need to discuss the replacemnet options. Gent has a 30lb bent aluminum plate as his. The texas parasol landing gear are lighter, and provide suspension as well.
