Re: The Wonderful World of Johnny 2x4 (FW)

I havent had experience with either of them, but from a quick look they seem okay. I would go for the 6 channel set, its not that much more and means you can add in extra functions and whatnot :wink:

Re: The Wonderful World of Johnny 2x4 (FW)

Not much progress. As i'm still waiting for stuff, cut the baseplate though. The chassis excluding wheels is about 700*340*44mm. Haven't had a chance to weigh it yet.

Also if anyone could recommend any cheap transmitters/recievers like the ones I posted on the page before it would be much appreciated.

giantcod 2.4ghz 7 channel, not bad and dam cheap

Re: The Wonderful World of Johnny 2x4 (FW)

Thanks for the recommendation! Although I think on a 2wd robot a 7channel may be overkill. My next question is do I need an external failsafe with that sort of controller or could I just rely on the reciever itself?

And I just had a weigh in, everything I have so far comes to under 5kg. I've got another wood panel to get, the batteries, some misc. connectors and screws/wood glue to still get, which I think should make the thing 7kg once finished.

its by easiest to get a receiver that failsafes, i beleive the giant cod ones do.

if it ends up underweight, do what i did. add a 2.5kg metre long axe to it

Good news: I found a frog!

Oh and I screwed the frame together aswell.



Please note this is going up against LS4 and whatever ungodly being TS2 turns out to be. Fun!

Re: The Wonderful World of Johnny 2x4 (FW)

700*340*70mm. I call it big boned.
Also, my father brought home a Hobbyking Hk-Gt2 transmitter/receiver combo he managed to procure from one of his friends at work. I'll try and wire up the motors to the sabertooth tommorow and see how it fares.

Re: The Wonderful World of Johnny 2x4 (FW)

Good news, Johnny 2x4 is pretty much finished! And father found the reason that one of the motors was making a wretched sound and fixed it. Turns out I screwed the gearbox on back to front when putting grub screws in. Just need to get some driving practice in now. And buy some binbags for when it fights LS4.
Expect photos tommorow. When I can actually get to my phone and upload them.
