Hello, I have a question regarding the max gross wt. of my model 111 it was originally built with a 2 stroke 582 after a complete rebuild and installation of an 912 ul.I would like to know if because of the more powerful engine would I be able to increase my max. gross from 1050 lb. to ? and if so how would I go about it ? I have some of the original paper work and that's where I got the max. gross of 1050 your thoughts ? Thank you .
