Been working on the ant design and a design for a tiny power switch-

It can be whatever size you want, but really anything that moves more than a few inches out isn't all that useful and will be prone to bending. As far as number of spikes, the best pop will be with a single cylinder with a large diameter, as pressure is lbs/in^2, so the more area on the piston, the better. Beyond that, flow rate is huge, as you can have an insanely high pressure system, but without the flow rate to back it up you won't be doing much.
Also, from a practicality standpoint, design it as a wedge/rammer that can either have a lot of armor added, or the piston, that way if the piston doesn't work out or gets damaged, you'll still be able to fight.

Robot build status
Moros(figured out what to call the 30lber): Design is closing in on completion, material sources have been identified. Hoping to have everything on hand by late november/early december. Chassis construction will begin in January. Main delay right now is I need to autopsy Mr. Self Destruct and see what survived or can be repaired. I'm also selling my 260z and if the weapon gearbox is dead it will have to wait till after the sale to be replaced.
Apollyon: Chassis component files have been sent to Team Whyachi, expecting delivery of a full chassis and spare wedge and horns by early-mid November. Once it arrives, assembly should take a long weekend at most.
Kobalos(Antweight): Looking into machining options, once those have been sorted the necessary parts will be ordered and construction shouldn't take long.
Apollyon and Kobalos are drawn up in such a way that if I wanted to, I could easily turn them into a kit, or just let people order their own sets of parts from whyachi/whoever else.

Decided to design a miniature Apollyon should I get time/feel like making it.  Weight as pictured(ie, no wires, fasteners, bearing weight) is 0.85lbs 20:1 sparks at 11.1v with 1-3/8" banebots wheels. Both together for some scale-

Decided to perform a small expariment along side the build.  The new hub weighs less than a standard colson without the Alu. hubs I use right now, so I can either go this route with the key in the LDPE wheel, or remove some material and put them on the hubs I've already got.

Have some hilarious numbers.
Assuming I can cram a 6s A123 in there instead of the 5s
2.04hp in the drive
Top speed of 13mph
Time to top speed of 1s, not accounting for what should assuredly be massive wheelspin
Whyachi has my drawings, mcmaster has a parts order, and now I'm waiting for stuff to show up. Hoping to have this thing driving by mid November so I'll have plenty of time for driving practice.
Current Whyachi order is enough to build the whole bot, a spare wedge and two spare hooks.

Drawings are done, here's a render of the whole setup.

Can't wait to see some of the video. Double Trouble (12lb melty) did a number on the Arena in its first fight.

Ah, ok. Not exactly an uncommon design. I think the new chassis & drive for Apollyon will work well, and the recessed claws should be much more durable than the old ones. 1/4" hardened steel (thinking 4130 or s7) embedded in the chassis like that will be hard to bust, add in some 1/4-20's to keep them pulled tight into the chassis and even some of the biggest spinners will have trouble removing them.

Working on the final tweaks to Apollyon's design. Still a little massaging to do to pull some extra weight out of it, but it's close-  Some info: Old chassis weight: 5.61lbs New chassis weight w/Ti wedge: 4.74lbs New chassis weight w/Steel wedge: 5.55lbs Old victors w/o fan: ~.4lbs New HH SC's: <.17lbs 3/32" fiberglass on the bottom, 3/32" Al on top, all internal framing is Al, thinking on whether or not upping to 7075 will be worth the cost.

I drove Zergling for him the two times they met in the brackets, also, quick correction, Spinning Tortoise got 2nd in beetles

Congrats on the performance at FI. I'll let you share the details.

Packed and loaded for Franklin, I'll be guest driving Sting, It Stings and Double Trouble.

Just ordered all the hardware needed to build up the new chassis and some new batteries to replace the dead ones, still sorting out some of the details for the composites, but I won't be able to make those parts till December at the earliest, so I'm not in a huge rush. Working on finalizing the layout and main connection locations so I can get my spacers, mounts and baseplate off to the Whyachis for machining. Planning to have Whyachi make a dummy baseplate that'll be used for component positioning for the layup, then will be remade out of kevlar for the final build. If all goes well, I'll have multiple chassis with a <30 swap time ready for the next event I take it to.
Apollyon is designed to the point where I need to finalize a few hole positions before it'll be done and ready for machining, also debating redesigning for a composite chassis and/or brushless drive. 30lber is my main priority at the moment, so it'll be a while.

That is the goal. I'm returning to the drive layout I used in Ruiner as it handled they gyro forces much better. If all goes as planned, I may have it running in time for Moto, possibly with a complete spare shell.

I've done some more refining of the layout/shape/mount points
