I have a LOC IV that has been through hell and back; still flying!
Great bird. Anyway, if you want to use yours for higher power than G,
you will definately want to get some 1/8" aircraft plywood and make a
set of fins for it that go all the way to the motor tube. Invest in a
spare centering ring and mount it immediately forward of the fins.
Fillet the fins and forward CR INTERNALLY before installing the aft
centering ring. Use some type of motor retention system to keep the
motor from spitting out at ejection, it's much easier and more reliable
than using masking tape. If you want to step up to some really major
power, consider a 38mm motor mount and centering rings. You will
definately need the fins to mount on the motor mount tube for this one,
and fiberglass them or use G-10 material. You may want to ditch the LOC
shock cord mount and drill a hole in your top centering ring and install
a 3/4" screw-eye there. For extra insurance and system flexibility, use
a quick-link to bolt it in place.
I hope this is some help to you.
Keep 'em flying, -Dave Stout-
