BUHOR Question
 

Good evenign Folks.
For a last week have building spad I found on Spad To the Bone -BUHOR.
Well,original version of it is 40 sized and have a wing span of 60 inches with fuse of 43 inches long.
THe spad i am building have wingspan of 82 inches.I increased the fuse up to 63 inches and going to power it with .61 supertigre.
I have a queston ..Do i have to alter an alierons?I re-inforced them but running them for a full lenth of the wing,in my case 38 inches long each.
I left stabs on the back alone .Folks,please advice on how it will affect a flight characteristics if i use my alierons untrimmed(original version suggest 28" alierons on 30 inch wing half)
Thanks ahead,
Mitty.

PS.Just posted same message on spad forun so excuse for repits :)
