RE: Do's and Dont's
No problem.
I can promise you this, if you're at an event and after an hour the same old 3D flying is making everyone catotonic, if you drag out a good looking scale helicopter and fly it in a scale manner, everyone will be up paying attention, the cameras will be clicking, and the video will be rollling.
Some things will drive you crazy though. It takes 20 seconds to pull the canopy and replace a worn glow plug on a Trex. It will take 20 minutes to pull the front windscreen and change the plug on a Trex600 covered by a scale fuselage. I just find it worth the extra tinkering.
