What ESCs are they? Don't recognise them. My natural immediate suspicion is the speedos as they're an unknown quantity.

these are the ones i got and they were working fine but i suspect you might be right ....i wonder when rangle box are getting 30amp botbitz esc...if only they could hear my plight

I can't tell if this is genuine or sarcasm :P

[Ellis]

I have the last two in stock sitting behind me, will send a PM lol!

I can't tell if this is genuine or sarcasm :P

to be honest a little of both

ok so i installed the new speed controlers and its unbelevable i can drive in a straight line and they are a tad lighter than the old ones so i now have 140 grams left to make a top and rear plate i can see me doing some serious attempts at weight saving to get it inside the weight limit

[suvv]

ok folks just to point out im not dead just been bit bizy been doing some experimenting and have made 2 discoveries firstly i really really cant drill a straight hole and secondly the reason for my wonky control issues after i replaced the esc is that some wheels are magically levitating and not touching the ground and i fear that i have far to much weight to recover as im sitting at 1.7 kg and without making a top and rear panel out of card i dont think im going to get under weight but ther is a plan im looking at carbon fiber sheeting...namely this http://www.ebay.co.uk/itm/2615050086...%3AMEBIDX%3AIT
in the hope that i can get the whole thing under weight thankfully no new events have been announced yet that i can deffinetly get to so i got time

[suvv]

successfully cooked my first esc dunno if this is a rite of passage or something i think the connections touched and shorted out as im using spade connectors as a go between the motors and the esc's to make removal and replacement easier although it was acting funny at first as once side would occasionally shit down for no reason though i think that was the same issue either way lesson learned gonna just solder them straight to the motors and ditch the spade connectors also made a comedy 2wd wedge thing that is currently operating under the name wonky built it mostly to kill time till parts arrived and ended up frying a spedo in it...i can see this getting expensive

You should put some pictures up

[Eventorizon]

There should have been no exposed contacts to touch and burn out. You need to use the female part on the ends of any parts that will be live. If you always use female then no matter how many things you plug in one after the other the ends will always be covered. (I am not sure if I have done a good job explaining that). The male ends go onto the part you are going to plug in, so starting at the battery you plug in the ESC, then the motor, so your motors (or whatever the last thing in the line is) should all have male connectors.
Note: there are exceptions and if you end up using XT60's or EC5's etc then the problems is almost totally eliminated as both sides are covered once you have assembled the connector.

meet wonky i cobbled together in 2 days out of offcuts of hdpe and polly i had kicking about in the scrap pile gona get a nice peice of titanium to make a blade for hte front and then watch it get dismantled by the first spinner it fights the second pic is an attempt to show ware the esc decided to eject lots of smoke but i dont think it came out to well on cam

and im only guessing at the short it was smoking like it was about to explode

I use these for testing, the plastic can be be slid on and off the clamps.
But they should only be used if the machine stays stationairy.

update /total redesign/fight report

been a while since i have done anything to this so i thought id bring everyone up to speed

since i last played with anything work descended on my life like the proverbial ton of bricks and i lost a bit of time i then suddenly i had entered a competition and had nothing to fight with so i panicky turned to harry and with his help..and me throwing money at him till i was poor the creature you see in the picture below was created amazingly it all came in weight even with 4 mm steel wedge and bumpers

iron games scotland:

being my first competition i was decidedly unsure how it was going to go but thankfully everyone was accepting of my nervousness the night before after a simple rewiring screw up i fried the entire wiring set up thankfully the link melted before any damage was done but it did mean that i was going into my first competition having never even tested the thing they let me chuck it in the box for a bit between pay to play fights and i discovered 2 very important things 1. allways check you have tightened the grub screws on your hubs 2. it doesn't handle like anything i have ever driven before...great but i was positive my wedge of doom was ready for anything......

fight 1 eggbeater:

i was nervous and i was drawn against the one bot i was worried about at the comp simply because it was a vertical spinner that i was convinced was going to rip my front wedge clean off thankfully he was having as many issues as i was he couldn't spin up and drive at the same time or at least not very well so my plan was to avoid the front and shove him side on and pit him activate calls out and i charge...and immediately turn left i take it a bit more gentle this time and get proper forward movement however i drive straight into the nasty spinning bar of unpleasantness amazingly the front stays solid on the bot and it does a double back flip and carry's on moving then his bar stops moving so i figure this is my chance i charge in and wedge myself in under the blade stopping hit from spinning however as i try to push him i find myself going backwards making a nasty grinding noise which turned out to be the hubs that had come loose from the motor shafts after some more pushing and some more back flips cease was called and egg beater got it on a judges decision i felt better knowing i could take a pounding but i definitely need to sharpen the wedge so that it gets under people.

fight 2 flatulance:

having tightened the grub screws i was determined to do better however my next fight was against flatulence who after much dancing between us both lifted me up and beached me on my rear bumper the fight was pretty uneventful and once again i had the wonderful noise of hubs spinning on wheels meaning i have no pushing power at all

fight 3 fqhwaghds:

this was more of a dignity saver attempt for me having won nothing so far and surely i couldn't lose to a bunch of cable ties and optimism...oh how wrong was i things started off well i was able to push him about and generally do something i opened the pit thinking i could navigate him round and in my haste to get back into the fight i forgot what my bot does if you give it full throttle...and turned myself directly into the pit

overall it was a good competition and i learnt a great deal including the wonders of loctite and that i need to practice driving this thing watch this space as i will hopefully have the designs up for the mk3 and who knows it might do better than all loses.

You did really well Something that may help like it did me was replace the grub screws with normal screws of the same thread. Then I really managed to tighten them. N as you said threadlock. What electrics does your bot run? Would it be ok to see a pic of the inside?
