Was a great kit to build. I added the 7.5 Ebay to make it dual deploy. Will be flying it with two RRC3 altimeters on a M1297 motor for my Level 3 Certification in March. Did require 2.5 lbs of nose weight to get CG correct. I also did tip to tip fiberglass on the fins and built the fin can outside of the airframe. Looking forward to a great flight.
