'The Thing' built from the three view in 'Silent Flight' in the early nineties. Lack of knowledge led me to having excessive elevator throws. I just kept moving the cg forward thinking the pitch sensitivity was a balance issue. This did eventually settle it down but I must have had about 1lb of lead on the nose and a fair bit of reflex. I made up a centre section with increased sweep, pushing the cg location further back and allowing me to remove most of the lead.
This wing was a quickly put together in an afternoon to test a few ideas. It was cut from pink foam. had a span of about 30" with a symmetrical section, low sweep angle and no washout. It was built to assess the impact of the wing section and lack of washout on roll authority, specifically to see if I could get axial rolls out of a wing that had the components of an aerobatic model.
The model was quick and soared well, but inevitably needed reflex so the rolls were terrible. I will try and solve this on-going bug bear of mine, I have several ideas to try out that may combat the effective up trim which causes barrel rolls.
