Should've had a go at lifting Cicatrix hiding away in the corner there.

Impressive servo you've got on that!

So in BW spinners alone, we currently have a:

Vertical Disk
Horizontal Disk
Horizontal Under Cutting Bar
FBS
And a Drum spinner.

Who's making a vertical bar spinner?

I may look into putting a solenoid in a BW. Did some research into trying it out on a FW, but found it wouldn't be very effectve and gave little advantages. Kudos to the Nipper guys for trying though.
I'm just thinking it'll scale down to BW size better.

We have tested a solenoid in one. Theres plenty of off the shelf ones around and loads on ebay, but servos seem to work better so we went for a servo. Ill try get a couple of solenoid test videos up. Most only have really short stroke so you have to mount them really close to the pivot point so they have to be alot higher powered solenoids than yu would expect as the weight on the tip of the flipper arm could effectively be 4kg+ Also we found they like to have a couple of mm of travel before they have any force on them. so you drop it down ike 2-3mm under the flipper arm so its already moving before it hits the arm. They do work but just not as well as a powerful servo. One could be made pretty good and it would be cool to see one done, Just as something different. What sort of power solenoids have you been looking at?

Can't remember exact figures out off the top of my head, but when I was looking into it for the FWs I could theoretically get the power of a LP (that's normal LP Tom!) system, but at a big weight, size and money cost. Plus like you noted, the stroke was very short and had little power to begin.

Be interested to see how you guys got on with it in a BW though.

Is there an active weapon rule in this class? was debating making a 4wd fbh but unsure as too the rules

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Yes they is a active weapon rule

[mattsdragons]

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

what would be a good parts list for this class? motor, esc's wise etc?

as i need an active weapon, BW bulldog it will be

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

its hard to say whats going to be the best parts to use at the moment.

People in the US are using http://www.robotmarketplace.com/product ... MINI2.html
Kenny is also using the Scorpion Mini

and for motors some of the mfa motors at technobots look ok,

Im using a 2x5a sabertooth in my full body spinner.

the 10a syren controllers look ok. anyone used them?

the modified brushless controllers look ok, there will be a few of us using them. might be worth seeing how they hold up over a few fights before alot of people get them.

you could always go for a 2x12a. They are more than capable of running any beetle and are proven to work in feathers so you cant really go wrong with them. and they dont weigh much.

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

What servo do you use for sloth? Once I figure out costs etc can see if it's worth it

May try and get some parts from the actual bulldog breed in this

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Syren controllers are just single channel versions of sabretooths I believe .

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

180 is using 2 banebots, carbide will be using 2 25a hacked ( Ordered ), and full combat machine will be using a pair of mini scorpions

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Im using a sabertooth 12amp, seems to work ok. and Haha, I just weighed the bear components of rocky (no frame mounts or pullys) and it weighs 1.5kg... I need to either need to use some untigravity technology, or lighten every thing, probably have to swap out half of the components, probably have to switch to a brushless spinner motor as that would save about 300 grams, and then lighten the blade. Shame, That brushed motor was seriously meaty and reliable. And the disk would become even less balanced.

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Take a video of you breaking some stuff with it first

[Bodge Job]

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Belts not here yet, so I can't, and it's not finished enough to run, so there is no point, I'll just switch it over, it would be sorted by the time the belts arive.

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

what ratio mfa motors are people using? thinking of going for the 6:1?

[PJ-27]

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Depends on which type MFA motor you've gone for?

I've gone for 30:1, but since I have 75mm wheels it has a little too much top end.
