Hi, I had thought about that, but was trying to keep my project costs as low as possible, I had hoped there would be more detailed drawings available online, or maybe a model plan. There are plenty of plans for model planes but very little in the way of helicopters, I may just have to accept it and work from the drawings I have. When I scaled them up (on my ageing laptop) for tracing at the size I want, the lines end up 5 mm thick! Do I use outer edge,inner edge or the middle? And are the drawings that good anyway? I have started drawing it anyway, I sometimes get too caught up in details, but I would like my model to be fairly close, small proportion differences can affect the whole look. I have airhogs twin trooper which has pretty accurate shape, apart from the rear rotor gear housing area. I must admit that it doesnt stand out too much tho. And it flies, so any scale inaccuracies are ok. It is a challenge to fly it tho, no gyro on this one. A lot of fun tho, and looks good in the air, the reason I am building a more controllable version, at a bigger scale. I will stick some photos on here once I have progress to report.
