Believe it or not one of the most effective types of jammers is also the

is illegal now-a-days for exactly that reason but are simple to make and
can be of more than enough power to temporarily wipe out communications
to virtually any radio controlled device.


And some things you really don't want to interfere with that will draw
attention. Controlled bandwidth jammers are pretty easy to make and way
less obnoxious.


More fun would be a hardened backyard toy chopper of your own, armed
with sharp steel rotor blades that could be used to slice and dice the
toy choppers of nosy neighbors whose devices violate your air space.
Chopper wars! It's the 'Merican way. One can envision the escalation,
all the way up to MINI NUKES, available soon from the NRA.

Cool idea, FOAD! How about missiles - already available!

Sharp steel rotor blades would damage the other aircraft, but would also be damaged by the impact.
Plus, if one came flying off while powering up, you could lose your head! The design of the blades
on my 'copter allow for strikes against walls, ceilings, furniture, etc, without damage to either.



Airborne miniature lasers...or maybe ground to air lasers.

I got one of these for the Sig. Don't think it would do much damage to an RC quadcopter though.

They're a big help in practicing a steady grip.
