    Sounds great! Look forward to seeing more electric lifter action!

    Bit unsure about 30a Electronizes controlling those drive motors, they're seriously huge, haha. The Electronize are fairly bulletproof, mind.

    Wondering about what you will go for battery-wise? To get the power you'll need you're more or less limited to LiPo... ?

    Keep us posted, this is going to be interesting.

      lots of work to update on, motors and full drive line fitted just waiting on some chain half links as the tension was all over the place, aluminium drive shaft assembly has worked really well and weights almost nothing,

      weight and armour issues at the moment estimated 10 kg with no rotational scoop weapon is going to be very teight,

      Will update photos and with a drive test prob early next week.

      how is the cheap lipo deal going, will need some 3s lipo power for this power hungry monster

          I recommend these guys for lipos...
          http://ElectriFlyer.co.uk/category/batteries/
          Every lipo we have we got from them and they have all been flawless.
          With the two CIM's, say a 4S 4Ah thats £38 with the current stock sell off.
          Or perhaps a 6S 4Ah is £58 :-)

          Note: Be a bit more descriptive with the thread name... New Robot isn't exactly informative or gripping.

            Main motor drive completed with chains and wheels fitted tested with batt all looks good, wheels from rs company called lug lots of grip but with an untrue front face causing the sproket to wobble slightly, packed and refitted a bit better but would benefit from front face mill skim. Drive seams very strong but not much space left inside to fit the rest of parts. pics up soon hopr to have a full drive test next week back on shift soon boo

              We have now confirmed a LiPo deal with OptiPower. 30% off all their range. We are just exchanging lists of FRA members etc and then you can begin with orders
