Q: How does the weight of whole Project Cedrus foil with wings compares to comparable setups?
Project Cedrus with Rocket wings: 2.6 kg / 5 lb 11.68 oz
Liquid Force Rocket v2: 3.7 kg / 8 lb 3 oz

Project Cedrus with Happy Foil wings: 2.37 kg / 5 lb 4 oz
Liquid Force Happy Foil: 3.5 kg / 7 lb 11 oz
F-one freeride 90/800 aluminum: 1.38 (mast) + 0.47 (fuselage) + 1.05 (front wing)+ 0.24 (stabilizer) = 3.14 kg / 6 lb 15 oz
F-one freeride 90/900 aluminum: 1.38 (mast) + 0.47 (fuselage) + 0.78 (front wing) + 0.24 (stabilizer) = 2.87 kg / 6 lb 5 oz

Project Cedrus with default stringy wings: 2.6 kg / 5 lb 11.68 oz

Other reference weights:
Slingshot Ghost Whisper 91: 2.7 kg / 6.0 lbs
F-one race carbon 95: 1.50 (mast) + 0.40 (fuselage) + 0.64 (front wing) + 0.18 (stabilizer) = 2.72 kg / 6 lb
