Hi Lucas,
Overall weight increase was minimal and rather that than lose the rudders due to hinge mounting failure.

I have seen the Mig fly on several occassions and it is capable of very slow flight so I don't think overall weight is critical except for remaining under the limit for competition whhich is why Wolfie removed so many engine accessories.

With twin JetCat 160s (lack of) power is not an issue !
