Yes I have been watching YouTube videos, Google searches, flysky website(didn't know u could download the manuals), and I got through about half of that 100+ thread on the nb4. I was wondering if anyone on here has the radio and has converted there's, if so do they have any issues? Also maybe if it was as easy as using the pro battery from the pro model. I wouldn't have posted a question without doing my own research come on seriously, hence the reason I posted the question. So thanks for ur reply I will check the Manuel now I know I can download them. And I guess I will just call flysky and ask if the battery swap works. Unless anyone who has done it differently or better I would appreciate u comments.
