John I don't think it is quite as bad as you say. Here is the exract from the Air Navigation Order that the BMFA quotes

(1) A person shall not cause or permit any article or animal (whether or not attached to a parachute) to be dropped from a small aircraft (defined by the CAA as a model up to 20 kg without fuel, Ed ) so as to endanger persons or property


I think the key here is "person or property"

There should not be people or property where you fly, so it gives some options, torpedos bombs and parachutes even toffees etc. As long as gravity is the only factor it shouldn't be an issue. And you keep out of the no fly zones, and take account of wind etc etc

Missiles are another story, the lack of directional control over missiles makes them a potential problem, unless you have access to a big desert like the guy above. Not too many of those in the UK.

Anyone tried elastic/rubberband powered missiles of lightweight foam. just use a servo to release a pin holding back the band releasing the energy into the missile. Might just work with the wind behind you :-)


Just my 2p
