Flip-Side's build diary

From the looks of your picture it looks like one of the gearboxes might not be on as tight as the other? (top one in the photo looks less tight) Not sure if that would affect it or not, but worth a try.

if the top one was any tighter it doesn't work properly

So it came like that? A bit unscrewed?

Also, is this with the grub screws in? If so it could be that isn't not working properly because the grub screws are too tight. Did you put those rings in that that guide I sent you suggests? Because if you're using grub screws you don't need to, but it would prevent you from tightening those screws if the rings are too big.

it didnt come unscrewed i unscrewed it.

and yes i put in an o-ring

I see, I just used grub screws and not an o-ring. Well, I tried the o-ring method first, but like you say I found it made them run quite a nasty way.

I would say, just use the grubs screws I ebay linked you to in your enquiry post and don't bother with the o-ring though someone else may advise you otherwise.

Yeah heard the o-ring might tear and wear off during fights as combot robots tend to stall and such often unlike other applications.
I screwed in regular M5 bolts into every other hole as grub screws and then cut the top off.

I'll try the o-ring for a while and if they wear off i'll get grub screws

Just bought a radio transmitter and reciever set

Did you go for the giant cod set in the end?
