Advice and recommendations on these components.

[Theo]

I've finalised my line up for my robot and this is what I've came up with. I probably won't enter it into combat until further testing and improvement. Please tell me if this line up won't work (I don't care too much about how good it'll be in a competition just yet) I just purely want to know if it will run okay with these components. Also, please suggest alternatives, preferably cheap and can be bought from Hobbyking. Switches and removable links will come later, possibly in a build diary. I'm just buying parts for now.

I'll be getting these drill motors (I might get some others with gearboxes)

Secondly, i'll use a couple of these speed controllers:

I'm still not too sure on this, but it seems alright for what I need.


Thirdly, I decided to get a transmitter/receiver combo for simplicity's sake. I've checked and they're available individually as well:

Battery-wise, these should do:

I'm not getting a LiPo for now because i'd need to buy a special charger. Mainly, though, these are slightly safer and cheaper.

These connectors also seem okay to use, nothing too complex:

Lastly, I'm probably going to use this cable:

So yeah, this is everything, I think. What do you think. Seriously, advice is welcomed in any area. Thanks.
