Default LED night B/Gs & RGs?

Hello All,

An interesting new feature for boost-gliders and rocket gliders (either R/C [Radio-Controlled], or F/F [Free-Flight]) would be multi-colored LEDs set into the wings and/or fuselage and tail surfaces, with lighting pattern circuitry to make them flash in various sequences. Such a model rocket could easily be built (or modified to be that way), and it would be great if one or more of the manufacturers offered such kits (or lighting system "add-on" kits for their existing B/G and/or RG kits). Watching the short video of E-flite's "Night Radian" 2 meter RTF electric motorglider *here* http://www.horizonhobby.com/airplan...-select-efl3650 (the video is about halfway down the "screen-page"), it inspired the following thought:

Imagine how, on a dark night (especially a Moonless one with a high overcast), such an LED-equipped boost-glider or rocket glider would look from a distance, rising into the sky on a line of brilliant light and then flashing or pulsating in strange patterns of multicolored light. In the darkness, no shape would be visible, and any observers might well suppose that the source of the lights might not be terrestrial... An R/C boost-glider or rocket glider could utilize radio control of the lighting system; so could an F/F one (a single-channel R/C system would suffice for that), or the lighting system could be pre-set before launch. And speaking of radio control, in connection with Free-Flight models:

RCAFF (R/C-Assisted Free-Flight) model airplanes were developed many years ago (Bob Eberle's modified Midwest Models "Sniffer" F/F plane may have been the first), and the concept would work just as well with F/F boost-gliders and rocket gliders (today's tiny micro-size receivers, servos, and airborne battery packs will fit in very small models). In the RCAFF set-up, the model is usually controlled only occasionally (to keep it from flying or gliding off the flying field, or into a patch of woods or other obstacles), although the model can be piloted continuously if desired. Such models are usually rudder-only, single-channel ones (just rudder control is sufficient). Most minimalist, starter models are two-channel ones (either rudder/elevator or ailerons/elevator), and in an LED-equipped RCAFF B/G or RG, the second channel could be used to operate the LED lighting system.
