Nice plane. The weight you gave is as shown? Anything from a good 46 to 60 2stroke or best 4 stroke 81.

IMO, if it weighs about 5.2 lbs. now, without covering...then figure about 5.75 to 6 lbs. after. (that's figuring with an iron on film covering...not paint )

Is there any radio equipment installed? (doesn't appear to be )
Figure about 6.5 to 7 lbs. after covering and radio, pushrods, etc.

With an 80" span...hmmm...a 2 stroke .90 would be about what I would use, at minimum...probably more like a 1.20

A 2 stroke .90 / .91 will add at least a pound and a half...so...you're looking at getting close to 9 lbs. all up wt. (maybe a little bit more, with fuel )

no radio gear is in it, just the bare airframe at the moment. the engine bay is fairly small...I pulled a BME90 (St90 converted for gas) out of the closet and it drops right in.... at ST2300 fits really tight and probably wouldn't have much prop clearance.

I have a Bandito Grande about that size and wingspan. Looks to be built similar. Few great (sport like) with a saito 1.20. Dont remember the weight.
