I think the best way to deal with it is to make the triggering mechanism capable of applying a lot of force quickly. Perhaps an electromagnet would be appropriate. I suspect it's also quite important to minimize the mass of the moving linkage pieces. Another possible solution is to place the pivot of the fixed arm very close to the flywheel and use a cam to drive the flipper arm. With proper cam shape, it would be possible to smooth out the force profile a bit and avoid loading the mechanism until the linkage is fully engaged.

I like electromagnets :)  I've been trying to use them in my bots for years.  The best-working friction roller clutch I had on Magneato used electromagnets to capture the mechanism and springs that spring it into engagement when I turned them off. It was a little tricky to get right but drammatically reduced the firing reset time. Pretty complicated though..

I built a new beetleweight and brought it to the Robojackets 20th Anniversary Competition yesterday. Its name is Impulse Response and it's an undercutter with inspiration taken from Silent Spring. I'm really happy with this design and it was pretty cheap and easy to make.

The full build report is here: https://ericwchin.blogspot.com/2019/03/impulse-response.html

It's been a while since I've done any combat robotics stuff, but it's good to be back.

Super happy to see you back at it. I thought Event Horizon was awesome in 2016 and since you ended up going to GT I kinda got excited (BSME, BSEE 2013 woot woot!).

I dig the name too, although it sounds like yall called it Event Horizon on the stream anyway, haha.

I remember being impressed by Event Horizon by then so its good to see you make new cool things! Hopefully you can go to Franklin in October or some other insect event in the summer and we can see more of your stuff! The Arduino was also a nice touch to mix the channels. I know Fingertech also has the tinyMixer if you ever need to shrink your footprint, but otherwise excellent work!

It looks like we both got some inspiration from Silent Spring and wound up with some strikingly similar bots. 

Maybe if all 3 of us make it to Franklin this year we can have a battle of the 3D printed undercutters!
