Team Fire Force FW build

Hello,
I am starting my very own build diary for my featherweight in progress.
I made the team name up when i was little so forgive it for sounding cheesy
last week I got the drills from argos (the more expensive £15 ones.)
they do 600rpm, is that more than the £12.50 ones?
It will be all wood :D (18mm plywood and oak so its tough)
there are pictures on my picasa account
BTW here is somthing really cool
check this out enter your post code and watch:)http://taxi.ba.com/
try with the photos

:l

Your link says page not found :cry:

Link not found.

here

i just had an idea.
skate ramp!

Looks good :!:
Are sure that the wood is going to be strong enough?
Also, how are u holding the wood together?
Looking very promising though! :D

Ply wood is very strong so it should be fine, I like the look of your motor mounts 8) you should remove the wires going to the drill motors and replace them with some thicker wire or they will limit the current going to the motors. Are you using the drill batteries and what esc? And the £15 drills are the same as the £12.50 drills, they have just increased the price again :sad:

the plywood is 18mm s its plenty srong enough.
the mounts are oak.
speed controller are botbitz when i get round to ordering them:(
oh yeah and drill batteries might be used till i upgrade

i'd bring some spare pannels to events if i were you.

18mm ply is strong enough make sure its mounted and secured together correctly

you wouldn't believe how much wood i used on it!
about 1-2mx50cm.
so i.don't have enough for spare.
i know its plenty strong enough.
i think its huge.
45x30x9.
it weighs 4.1kg like that and my aim is 8kg

Actually looking pretty good mate! Looks very neat and nice. I have to say, 18mm ply may stand up to non-spinner combat, but it won't much like full combat. I am guessing you don't intend to enter full combat anyway. Don't be fooled by the stresses involved even against ram-bots, though; a wedge corner doing 15mph with 13.6kg behind it will do damage.

Looking forward to seeing how this turns out. :)

it only looks good because my dad took over most of it:(

Ok because i was trying to save a new thread I posted my stuff in my GS links section.
PLEASE SOMEONE ANSWER THIS
anyone I really need help and want to order ASAP.

1stly the servos with carbon fibre gears, (worth a try?)
Servo moding failed last time and I think it could only get worse with the carbon gears.
seccondly, I have found M5X5 grub screws on the site (I know M5X8 is ideal but they dont sell those)
could I use a nylon M5 screw. screw it in and cut it down?
help appreciated

Thanks in advance (hopefully) :)

plastic bolts are not a good idea. happy?

sorry to double post (or triple)
but I want this to be legal for robots live at Deeside (I know the heavies get main attention but if I just get 1/2 fights that would be a great learning curve) I will be using a Giant Cod tx and rx which I am aware this wont failsafe (Its just a simple wedge with 2 drill motors- is that ok?)
botbitz 85a with drill motors and drill batterys in a 12v 2amp pack.
I can get some sort of LED powerlight on it.
Wheels have been ordered for a bit and Im still waiting on arival.
What else will I need to pass a tech check?
also will the Giant Cod/Shark tx and rx be legal on a spinner ant? (I guess not)
and will the TX work with a different RX that wil failsafe
thanks in advance again, again
edit: cheers haz but are grub screws plastic bolts? (sorry I dont quite get you)
Thanks

nylon is a plastic.

failsafing is a must! your GC gear and botbitz will failsafe anyway, so thing.

Having plastic grubscrews is not a good idea, make sure you have a removable link for your robot and a power light which only lights up when the link is in. It must failsafe but what your using should failsafe but test it.

all in there, remember sharp edge protection easy to access link failsafing and a power light (link and light need to be near each other)

alex

yay cheers guys
thanks for the answers

Fine, the Botbitz speedo will do the failsafing.

If that's Robochallenge and it's been more than three weeks, email them a reminder & mention Deeside. Good lads that have a habit of missing orders.

I don't believe that there is a failsafing RX for giant cod.

Spinner ants will need a failsafe on the spinner channel at least. Since the throttle traditionally stays as running, I'd recommend putting a failsafing speed controller on the throttle channel to power the spinner.

Everybody was less picky abou Napalm Death's drive going around in a small slow circle. There may be a bit of give there

The Giantcod stuff should failsafe on the throttle channel at least, so for an ant spinner should be fine. I'll check my own gear if it'll failsafe with anything else.

And a cradle to sit your robot on, not just 2 crappy bits of wood wedged underneath lol ,make one a bit better,, best to get yourself all in order now. It may be just a wedge but flying off the table with no cradle could cause a nasty injury to someone close by

ok thanks everyone
@ady building a good cradle should be no problem I have improved at woodwork
are there any giant shark brushless speed controllers that will guarantee failsafing?
3weeks is kind of scary- you cant have a robot with no wheels!

The important thing foraq cradle is to have the wheels off the ground, at champs I used a 120mm by 250mm ram as a cradle.

ok ive learnt lot from this thread.
but I'm still non the wiser on:
my situation is I am looking to order from giant cod. everything in one parcel and I know nylon grub screws aren't strong but if I have 8 of them in the motor at once and you get about 20 for 60p, will 5mm reach the plate in the motor?
surely someone has tried it, I could probably find out tomorrow but does anyone have the answer?
next, will this esc on the throttle channel of my giant cod?
http://www.giantshark.co.uk/speed-contr ... 05436.html
also servo modding failed last time, could I buy spare gears and swap the gear with the limiter for a gear without?
I hope this makes sense.
thanks loads for your reply
Archie

For 60p try using nylon grubscrews but I doubt they will work unless you tap the holes in the motor. I think that esc will fail safe but I'm not 100 percent sure

i don't understand why you're considering using nylon grub screws, they almost definitely won't work (probably won't be able to tap the holes in the drill motor casing) and even if they do work they'd probably wear out after a little use. for a saving of less than a pound per pack of 20 screws what is the point of even trying? these grub screws will work fine:

http://www.ebay.co.uk/itm/m5-x-5mm-stai ... _969wt_650

edit: btw i have used these exact grubscrews before and they've worked perfectly fine.

ok I was just trying to get everything into 1 order.
if i buy from eBay will the 5x8s be too big or will the 5x5s be too small?
thanks once again

5 by 5 have worked fine for me before

Actually I wouldn't recommend using the 5mm long ones, unless you have already ordered. We bought 5mm and soon went to 8mm long, as otherwise you only have a thread or two holding the grubs in position. Check my YouTube video to see the 8mm ones, they fit perfectly in all drills I have used.

We use 4 in each motor, you could probably get away with 2 in a lower power drill setup.

a not very updating update.
robot isn't going to deeside as robochallange haven't sent the wheels.
thats awful service. over 1 month waiting.

So email them & if they don't get back to you by Wednesday, PM me.

yep they have sent an email and apparently they will be sending some new red competition wheels.
that sounds coolio

What size wheels did you buy/are you waiting for? I've got some 100mm blue wheels spare that I could lend you for the weekend if that's any good?

I'm not sure 100mm quite fit.
shame the event was less than 1hr away
anyway it will come back Better and more wooden for barnsly

sorry its heen a while.
should my BotBitz 85 light up when I plug a battery in?
progress

My hacked TZ85A don't light up
In fact when I pulled them apart I didnt spot a LED

Looking good!

Didn't see any light in the TZ85 I used for Prodigy Evo.
