Gentlemen, I could use some of your knowledge and experience building a stooge. I generally fly over concrete, but will move to grass for the larger planes.
Question follows the description below.
Largest planes:
I have a few larger planes (thanks to FredV4), a UKEY .35, and two Gotcha-Streaks I doubt I'll ever get above 48" WS with engines no bigger than a Fox .35, and Magnums, Norvels, and an older OS no bigger than .25. Everything else is .15 down to .049.
Weight plates for stooge:
Plates of 1/4" steel, cut into 7.5"x12" at 6 lbs each.
Stooge basic construction:
A box frame of angle-iron, such that the plates drop in to provide "suitable/tune-ble ballast." My arm/shoulder gets worn out moving a cinder block to the launch area. The last plate in the Stooge layer-cake will most likely be 3/4" plywood to support a hinged release operated by a garage door remote. The "release" actuator is a car door solenoid, and connected to the spring-loaded release pin via a weed eater throttle cable.
I bet 6 lbs (plus frame/plywood) will hold a 1/2A plane...but just how heavy does the stooge need to be to retain the largest planes in my fleet?
I'm all ears today.
Thanks much, Gents!
