Re: Triggering the Vehicle
I was thinking of using some sort of hook or claw mechanism that attaches to a loop on the back of the vehicle. It would be released by pushing the hook out of the loop or opening the claw with the pencil.

Re: Triggering the Vehicle
There is the option of sticking the pencil in a loop of sorts on the vehicle and then pulling it out to release the vehicle, seeing as the rules permit that the pencil be part of the actuating mechanism.

Re: Triggering the Vehicle
I plan on using two hooks that are connected (forces the vehicle into alignment)

Re: Triggering the Vehicle
So using the pencil as part of the release mechanism is ok? At the Mira Loma Invitational I saw a few teams hang their GV off the pencil. I'm not sure if the wording in the rules indicates this is legal?

Re: Triggering the Vehicle
Rule 5i. "The pencil may be used as all or part of the release mechanism".
But do note, also in that rule, "They may not touch.push the Vehicle, or the Ramp, to start it or hold it while actuating the release mechanism" so you may not, for example, use one hand to pull the pencil out while the other hand (or part of the same hand) applies counterpressure to the ramp.

Re: Triggering the Vehicle
When you stick a pencil through a loop, the pencil has to be able to stay in place and hold the vehicle without anyone holding it in ready-to-run configuration?
If so, how do you keep the pencil from slipping out? Or does the weight of the vehicle keep it in place?

Re: Triggering the Vehicle
The rules aren't quite as explicit about "has to be able to stay in place and hold the vehicle without anyone holding it" as they might be, but rule 3a does say "A releaseMTV<=>Operator wrote: ↑January 16th, 2020, 6:32 pm When you stick a pencil through a loop, the pencil has to be able to stay in place and hold the vehicle without anyone holding it in ready-to-run configuration?

mechanism must be included as part of the Ramp to hold the Vehicle in the ready-to-run configuration until triggered by the participants." 5i says that the pencil may be all or part of the mechanism. No rule says that the team members may be part of the mechanism.
Put that together, and I think you're right - the vehicle must stay in place without someone holding the pencil.
In the configuration you describe, the weight of the vehicle is usually sufficient to keep the pencil locked against whatever hole it's poked through.
