Bruce:
I've been using a Solar/Capacitor discharge Launcher since 1991
Here's a 2Pic of the beast, If you'd like to build one I'm fairly sure the story is still in the library section of the Narhams.org web site under Tech-Tip-007 self contained solar launcher.
Looking at the front photo the rectangle attached to the lexan lid is 2 6v 50ma solar panels wired to produce 12v 50ma. which charge a 56,000mfd 16v capacitor in just under 45 seconds in full sunlight. Plenty of juice to fire estes, quest and coperhead igniters. I've even managed a 3 motor cluster, but prefer to use an external battery drop to an on-board 40amp per contact H/D DPDT relay for cluster ignition. All controlled by a custom fabricated
hand controller and 30' of 16gage control cable which store in the front 42" tri-pod 2" x2" square alum. tube leg. Battery drop cables and 36" launch rods store in the other two legs.
Rbecky:
This launcher has everything on your list except being light weight and wireless, the unit with on-board 12V battery back-up, Solar panel, controller & cable, drop cables and 1/8th, 3/16" and 1/4" x 36" stainless steel launch rods tips the scales at a tad over 45 lbs. I'm afraid wireless would be ToOO dangerous due to stray signals.
She has H/D Relay and stainless steel micro-clip whips for up to 8 motor cluster. Stainless steel built-in 16ga blast deflector and director also have Rod holders for 1/8"-3/8" rods. launch angle
adjustments are made by pressure fitting in the blast box with azimuth adjustment by 360 degree rotation of the entire launcher head around a central swivel.
Cls:
Most of the electronic/electrical hook-up and connectiors are on a "works in a draw" type semi slide out tray, but I really messed up making the rear panel power supply selector door hinge up instead of down which would have made servicing internal components easier
Function slector switches, relay continuity light and Capacitor dischrarge lamp are mounted on a recessed front panel with bottom hinged cover door. By isolating all the electronic/electrical components in a semi sealed compartment below the deflector all the corrosive chemical smoke and by products are kept out making reliability wonderful. Clear up with fantistic and paper towel and a squirt of WD-40 on the clips and rods is all thats needed for maintainance. 13 years or hard use and I've only had to replace 1 bulb, one set of cluster clip wire wires and change the micro-clips about once a year until I got the Stainless Steel micro-clips.
You find/have Launch systems you like... This one I is for me..my ultimate!
