Hey all - I was at the last Nuneaton event just to watch. I was going to be entering this AWS but I've been so busy with work I doubt it will be finished in time. I messed up the armour last night and have to start it again :(

I'll definitely be ready for the next event though! I'll post some pics ...

Me & a friend will be there, probably just after 11. Not competing though, just to watch and learn! I hope my ant is finished by the next AWS.

Is this event open to spectators? I was going to be competing but won't be ready in time.

So the other NiMH packs arrived - the 210mah one is too heavy, but the 7.2v (6 cell) one works!! It has to be wired straight to the battery rather than through the receiver so I was concerned about it breaking, but it seems fine so far.

I'm in the process of building my first antweight (and actually have started thinking about the design of a second), and the number of servos available is quite overwhelming. What would be the recommended servos or servo specs for use by a lifting arm and a flipper? I know they are pretty much the ...

Ok thanks. Which charger would you recommend?

Thanks for all the replies.

Wow I didn't realise how much better LiPo batteries are! Crazy cheap too. Yes that first link is the battery I have. What is the risk with LiPos, i.e. how likely are they to go up in a fireball? I've got to wonder when they sell special fire containment bags to charge ...

Ah ok, thanks. I don't have a spare but I'll order one, worth a try! How much do the 210mah packs weigh?

Thanks!

Yeah I suspected the battery but didn't want to believe it as the battery only just fits with 5 cells :oops: . I did look for 6 cell packs but couldn't find any (currently using 120mah which lasts ages). I am wary about going with lithium batteries for now as robot building is new to me.

I ...

I'm using a Sabertooth 5A speed controller, connected to a Lemon-RX receiver. I have a single servo connected to the receiver, and am using a 6V NiMH battery. When activating the servo the Sabertooth cuts out and resets. I have read that there is a weak BEC on the Sabertooth so I connected the servo ...
