fusionfab Posted January 26, 2022 Share Posted January 26, 2022 Hey everyone, I am new to the group but have no experience with glass aircraft construction, aside from the cowlings and wheel pants for other builds. I’ve scratch built two planes start to finish but they are tube/fabric. I have been interested in starting a cozy MK4 for a few years now as my final build for my family. So my first question is strictly out of curiosity, but what are the benefits of doing pillar style fuselage reinforcements (like the velocity) between the dash and the firewall when compared to doing the center bulkhead behind the front seats?

zolotiyeruki Posted January 26, 2022 Share Posted January 26, 2022 I'm thoroughly unqualified to answer, but it would seem to me that a center bulkhead could be less bulky, while the pillar-style reinforcements allow the entire interior of the aircraft to be free of obstructions. I imagine that type of design is also what allows the gull wing doors on the Velocity. Quote Link to comment Share on other sites More sharing options...
Voidhawk9 Posted January 29, 2022 Share Posted January 29, 2022 The entire top of a Cozy can open up?

Voidhawk9 Posted January 30, 2022 Share Posted January 30, 2022 Hard to compare, the two fuselages are very different. On one, the top opens and is non-structural, on the Velo the sides open for doors, thus the top is structural. Apples and oranges. The different options may appeal to different folks.
