Here is a customers PSS Nimrod MRA4 built using Bucks-Composites materials.
The plan and construction took the best part of 3 years, resulting in a 1/15 scale model of 2.6m span weighing 10kg and a wing loading of 28oz/sqft.
Covered throughout in Bucks composites Formula 50 resin and various weights of cloth, mostly 25g with layers of heavier cloth on the underside of the fuselage and some strengthening inside around the same area to take the launch and landing abuse.
What a wonderfull project.
