Horace, I think there are exciting things coming to CL in the upcoming years. I'm thinking there may be a resurgence in CL flying, as the trend seems to be further local government restrictions on RC flights because of onboard photographic equipment. I don't see how someone can arrest someone for participating in "tethered flight", although anything foolish can be possible. Electric flight is adding new dimensions to flight with new electronic timers for ESC's from places like RSM Distribution. Now, the impediments to multiengine aircraft can be overcome by having all motors started at the same time and stopped the same time. No longer does one have to ensure that the trailing engine has enough power to continue sustained flight with the outboard running out.
