Default old cg sukhoi 26mx

i recently aquired this plane in a trade,and upon further inspection i found it to be quite a abortion!! it was built very shotty and the wing was butchered! i have since removed all the covering and found the fuse and all tail feathers to be a-ok,but i had to commit to re sheeting the whole wing after going over all the structure parts,now i know i'm going to gain some weight on the wing restoration but not much,my ? to whom ever is i want to put a gas engine on the ole gal after restoration?what would be a good auw too shoot for and what would be a good engine,now also keep in mind that i will'nt be doing x-treme 3-d so a da-80 is'nt what i'm looking for,i want to be able to do most of the maneuvers without being x-cesively over weight. i'll be incorporating all the mods i can,like moving the lg to the firewall and mounting servos in the rear for ele. and rudd if ness. i do'nt want to go 4-stroke either! would a g-26 be a good choice? tia for all responses,again what would be a good auw and gasser to install,thanks........john

I'ts been a while since I built one of these so hope the following helps. In resheeting the wing use 3/32" balsa. The original was a strange thickness (between 1/16 and 3/32) so you will need to alter the wing saddle to accomodate this. Fiberglass the center section for added strength out past the fuselage sides. A G-26 should work however be aware that the fuselage construction is very light so you may need to add some Warren Truss bracing for absorbing the additional vibration. All up weight shouldn't exceed 11 lbs and 10 or lower would be better as this is in the size range of a standard pattern plane. Let us know how it works out.
