Electric Axe featherweight - first build of FW

[Roboteernat]

Been wanting to find a suitable battery for my botafter realising I only have 3S batteries... oops, bit of a stupid error there... but s I have an electric weapon I need to go for a 3300 or 4000mah battery.

Am tempted to go for he Turnigy heavy duty 4000 4S 60c lips pack from hobbyking sadly out of stock for U.K. Sales, prob due to their price reduction to £21.11
Otherwise it's the 3300 4S for £19.40 sadly out of stock too.

I'm going to assume these are suitable and hopefully get them soon

Turns out the 4000 battery doesn't fit into my design...
