General questions for first robot

BULLLEEETTTTTPROOOOOOOF

[Remote-Controlled Dave]

That's starting to get irritating

Glad I'm not the only one.

[Anoptimistprime]

Well I'm not at the aws so I have to make up for it somehow

[Shrike]

Moving back to the topic...

I have done some quick maths, and so far the total weight of the robot is 83.08 grams (without chassis, armour, weapon or battery). Is this an ok weight, or should I start bringing it down now?

Also, can anyone recommend some good batteries (either LiPo or NiCad)?

[Remote-Controlled Dave]

Seems like a decent ground weight to me. Gives you a good threshold to play with for the rest of it.

[Andrew_Hibberd]

That seems a little heavy for just the basic parts, are you able to post your part list and weights?

[Shrike]

Here is the list with number of items and weight included:

56:1 Mini Metal Gear Motor (x2) --- 16g
Sabertooth 5A Motor Driver For R/C --- 21g
Micro Metal Gearmotor Bracket Pair (x2) --- 0.58g
1/16" Axle Rubber Wheels- Internal Set Screw (x2) --- 24g
DSM2 'orange' 4 Channel Micro Receiver --- 2.5g
18mm Baby Outrunner - C18-15-25 --- 13g
Robotbirds Pro 6 amp Brushless ESC V4 --- 6g

Any advice or criticism is welcome.

i would advise against using a sabertooth in a spinner, they are very big and heavy.
go for a waller board or some bane bots.
any reason for the 56:1 over the cheaper ebay 50:1s?

[Shrike]

I am using the 56:1 as they are easy to access where I live, and I do not like using eBay if possible. I will have a look at other speed controllers for the drive motors, as you have suggested.
