Anti Hyzer V.2 antweight fbs

Version two of my catbowl spinner...

Things that needed improvement:

1. center of gravity, the first version was over 2.2 inches tall and only 4.75" wide so it was very high

speed stable but low speed understable, thats how it got its name too

2. chassis, it had so much flex because i used one single piece of carbon fiber as the entire frame

3. shell, it was a great shell but it deformed under hard hits around the teeth because it was stainless

4. drive, the first version used sanyo micro gearmotors this version will use spark gold 20:1s

5. weapon motor, previously i used a park 400 with an s7 drillshaft it worked perfectly but lacked the

oomph i was looking for in hits it would have enough torque to self right but only topped out at 6300rpm

using an airplane tach and electrical tape for index


soooo heres the new stuff

Full hexel texalium frame i love this stuff lots more flex then carbon but twice the shock load capability

using carbon fiber angle for corners and baseplate mounting using m3's

spark 20:1's using custom bonded minisumo wheels that fit over the gearbox and polulu motor mounts

with a 1/4" block of delrin used as motor clamps.



also the motor layout allows me to actually drive this robot unlike my last wheel layout that left me with about as much control as a melty

and my favorite part.



The new weapon motor park 480 low kv version with a 7075 aluminum hub that

bolts into the motor on 2 axis and will allow my overall height of the robot minus the hub to be .75" tall

and the rough layout





input is always welcome

nice, i like the wheels. and the weapon hub, should help save the motor some

i just started turning down some s7 rod for a 4mm motor shaft. i think if its going to break it will crush the motor can now

Alright so the robot is complete. the shell is balanced to about 1/10th a gram using lead tire tape(about .4gram) and a magnetic balencer for airplane props so hopefully i dont screw it up putting the teeth on

as it is right now without teeth it sits at 14oz

some pics...

its alot roomier than my last antweight so I was able to heatshrink, shoegoo, and cable tie everything down and secure.



sitting at just a hair over an inch tall with 1/16" ground clearence on the shell and 1/8th on the robot its looking fancy




Using a piece of black tape for index I was able to tach it at just above 6500 rpm top speed. With a full charge I was able to get a solid 7 minutes of full speed weapon with driving so under combat load on the weapon motor it should last a full 3 minutes.

and I like to list my stuff for others so here...

1. .059 carbon fiber about an 8"x8" sheet
2. 3" of carbon fiber angle with 3mm thickness
3. 32 m3 buttonheads and 22 aluminum m3 locknuts
4. polulu sanyo motor mounts 4x, 1/4" delrin blocks under for spacers
5. fingertech spark gold 20:1 x2
6. custom wheels with 20a durometer tread
7. fingertech tiny esc x2
8. robot marketplace v tail mixer
9. dys 30 amp esc
10. park 480 910kv weapon motor
11. thunderpower 325mah 45c 2 cell lipo
12. 1 foot of deans 16g wire
13. 5 servo male leads for shortened signal wires
14. 7075 aluminum rod 2.25"x2" for hub
15. titanium shell from japan
16. shoegoo for shock mounting reciever and v tail mixer
17. couple zip ties and deans plugs


anyone with any ideas on a micro switch pleasseeeeee let me know!!!!!!!

Looks really sweet!
Try nor to modify that roll ring on the bottom when putting on your teeth, thats where all your ring strength is

youre right cody, I ended up with an oval shaped shell on my first ant because I cut the ring. This time im going to use about 6-12 m3's to hold each tooth in place with washers on the back to spread the load out.

nice call alex they are fingertech sumo wheels!

and what do you use for switches on your insects?

top secret how I aquired the wheels, I get the not-so-much discount but do micro deans really work I have a bunch laying around and I never use them because the contacts are freaking tiny and would seem to bottleneck the amps ? maby im way off lol

tomorow ill do some destructive testing to see when they fail if it holds together without melting at a 50 amp shock load to simulate a 250 watt motor going from full speed to dead stop like a weapon motor does I think it will be a winner.

someone should make a mini whyachi style screw switch for insects, I would buy a bunch

I agree with that. The current Whyachis are too big and expensive for anything under hobbyweight.

I keep tellin' you. Micro Dean's will be fine. I've pushed more current than you will through a JEST connector. If you get for realizies Micro's, it'll be more than fine. It would save soooo much space...

okay seth ill try it, im still afraid of how tiny they are but I supose it will help with making a removable link.

I vote JST too. I've never had a problem with it.

so I put teeth on in the form of 1/4" grade 8 bolts on the shell today and started hitting some stuff and although it is very very powerfull and spins to the moon I know its going to destroy my shell in less than one fight

so after gcrs and I self destruct its going to be back to the drawing board to do things the right way with a titanium shell of real thickness.

at least im having fun learning along the way...

if only i was to the same point as you on your fbs... hopefully i won't run into self-destruction on my first few tests.

can you post some pics of it with the teeth on?

shure heres the top view... 3, 1/2 oz 1/4" grade 8 bolts with 1/4" washers



side view on the robot: about 1/4" ground clearance of the teeth... not at all how I wanted it but hey its temporary... until I design a third revision to this full body spinner puzzle. it seems like I either go too little weapon motor or too much next version will be a nice blend of the two




for actual combat after my first match when I destroy this shell Im working on bending a spring steel edger blade to use as an overhead bar spinner, to at least pose some threat to something besides itself.

how fast is the spinup? and can you rough estimate its RPM? (KV of the motor and voltage applied)

using electrical tape for light index and an rc airplane tachometer I clocked it at a healthy 6300 rpm +-100 with the tape index variable. so it spins scary fast and spin up time is how smooth I use my throttle. it will go to full power instantly if I give it full instant throttle it will go up on edge and jump around and blow white sparks at least 5 feet away

the kv of the motor is 910 its designed to swing a 12x6 airplane prop so my little ant shell really dosent phase it my battery is a 2 cell thunderpower 45c 350mah after a full battery the motor is cool and the battery is warm.

If that's scary fast, then my estimate of 10k rpm on my fbs might be even more so I hope to have spinup be about 2-3 seconds, under control that is you should test it out on cardboard to see what happens

also, how long does it last on a full charge under battle condition loads?

it will blow through cardboard like its not there lol

it puts nasty gashes in my hardwood test floor walls.

and 10k is pretty high i would worry about the shell stretching and wanting to coin itself at that speed some objects arent ment to spin that fast when you start to get into that high of rpm you have to add things like rings to keep stuff from streching because at that speed the shell is trying to blow itself up.

for example my shell with the teeth on at 3/4 throttle or around 4 thousand rpm will start to develope a harmonic due to the geometry and material properties and wind resistance and stability of its construction when i break through this harmonic the shell starts to grow and at full throttle i would say it streches a full 1/16" on either side or 1/8" total so if i went to 10k i would anticipate it would start to split if it didnt have a band around it to retain it at high rpm

sounds like it can handle a multitude of fights without problems if possible, could you even post a video of it? that would be really cool to see it hit stuff and hear the harmonics you're talking about and sorry if i'm being excessively nosy...

tomorow ill have some video up of it hitting some full spraypaint cans as tradition of my last antweight( kind of a destructive method of a paintjob)

and thanks for the optimism and no your not beying nosy at all.

but the shell is seriously like 28guage titanium its soft enough that I anticipate either rolling a tooth over or pulling one through the shell on a solid hit at high rpm. if i play conservative and dont go full throttle it might stay intact but thats no fun im looking for sparks and a big hit

where's those videos?

I took them so he doesn't have them.
but I don't have them either cause i left the camera at work... haha

(but don't tell evan i told you this, but it was kind of disappointing...)

yea it was a total fail i tried to hit the spray paint can and drove into a pile of sand and locked up both fingertech spark gold motors so after a cleaning and lubricating its back and ready to try not to fail again, its really hard to drive because i have no idea witch way is forward until i put lights on
