It was fun brining new life to this older frame. I liked the Apex so much I couldn't pass up a good deal for this used frame. I was able to loose 7.89g by using titianum screws all around the frame. That dropped the weight of the frame from 121 to 113.11g which puts it in the more mordern frame weight class. I been flying it with a 1000mah 6s battery which brings the weight to 686 with a Gopro 8. I feel most confortable in the 680-720g auw since I've been flying 4s for many years and it's what I grown most comforable flying. I still need to try diffrent props on it to to see if I can get the feel that I am looking for.
