4” Bullpup 12B Scale (Composite Warehouse) Build

Looks nice. Probably no need for big fillets

Maybe just 1/16” radius.

Launched the Bullpup yesterday on an I170. We had about a 9 kt wind. It had a little wiggle off the rail and weathercocked. The rest of the flight went well. Altitude was 1500'. Motor and drogue blew out the back as planned followed by the main out the back at 500'.
The AVbay included 2 Quantums and a GPS. The second Quantum provided backup charges. All Charges fired. The backups were not needed.

Don't suppose you have the finished weight/CG data for this (without motor)? Wondering how it compares to my buddy's build. He's getting some marginal stability numbers.
