Thank you for posting that, George. There's even a 12-channel one (see: http://www.ebay.com/p/Wireless-12ch...5.c100005.m1851 -
it's listed at the bottom of the page you posted) that's only $36.59; w-a-y overkill for the average individual model rocketeer's wireless ignition needs, but perfect for club or group launches. As you mentioned, I'd go with a relay ignition system, as it could use very short ignition leads at the pad, which would have *very* little voltage drop between the battery/batteries and the igniter. (Centuri's Servo-Launcher [see: http://www.ninfinger.org/rockets/no...a/72cen052.html ], which was electrically similar--it used a long length of pneumatic tubing with a plunger-type pneumatic ignition button at its far end--needed only *two* Photo-Flash "D" batteries [alkaline "D" batteries could be used instead today] to do the job that up to *six* Photo-Flash "D" batteries [as the catalog citation says], acting through 15' igniter leads, would be needed for if the Servo-Launcher had had ordinary igniter leads.) |
