Step 3: Modify the latch

The next thing I did was modify the latch. Normally, when a cat steps on the plate-trigger (Pic1), a metal rod is pulled which undoes the latch and sends the cage door slamming down (Pic 2). You'll need to deactivate the plate by detaching the metal rod that connects the plate-trigger to the latch (Pic 3).

Next, you'll need to make your own rod to attach the steering mechanism (the new trigger) to the latch. I found a stiff piece of wire and bent it into a hook (Pic 4) and then attached it to the latch (Pic 5).

Finally, the last step, and possibly the most crucial aspect, is attaching the rod to the new trigger (Pic 6). The steering mechanism for your car may be different from mine, so I cannot give any specific instructions. However, I can offer this advice:
  • When adjusting the trigger sensitivity, I found that lengthening/shortening the rod was the easiest way.
  • You can adjust the sensitivity further by bending the latch hook (Pic 5).
  • When the trap is set, the trigger/steering mechanism should be pulled taught toward the trap's door.
  • You may also want to slightly bend the rod away from the cage so it doesn't rub against it when the trigger is activated.
This is a great idea cause raccoons are extremely smart and learn bout the trip plate.they reach and step over it.i so love this idea.

What scale rc car did you use for the electronics?
This is hilarious! What a clever form of bird control. What are some <a href="http://www.burnsbirdcontrol.com" rel="nofollow">bird control strategies in arizona</a>? I'd appreciate your help! Thanks!
Those parts are from a New Bright vehicle. They are cheap and modular which makes them great for project parts!
I don't get it. regular trip plates work great (atleast for the wild boar cages I'm familiar with) . Whats the advantage of having it RC'd? If you just did it to do, thats cool. I think i'd much rather have a normal trip mechanism if i were trying to trap something though.
Yes, plate triggers work just fine if you're not concerned about what walks into the trap. For people who practice trap-neuter-release, they may want to capture a specific cat, not just the first one that walks into the trap.<br /><br />Or perhaps you want to trap a whole litter of kittens. In this case, an RC trap allows you to wait while all of the kitten file into the trap before closing the door. The RC trap has a very specific application.
I understand now. Great job then!
TNR is a beauiful, feel-good excersize. Unfortunately, the now-sterile cats still eat the song birds in the neighborhood. This is why I adopted and keep my 2 sterile cats indoors. They'd love to get out, but my bird population is doing pretty well, in spite of the neighbor's free-roamers. My chickens are a little less stressed as well, which means more eggy-goodness for the family and the neighbors.
this is great - we were just watching last night a coon go into our trap and thought , why not remote control this thing instead of waiting for the sneak to trip it ? And to boot we are also in need of catching a couple ferals to do just that.. TNR. What timing , I guess I'll have to do the mod. <br /> <br />
