Ahhhhhhhh Mr Elam you seem to think i know nothing of vapourbots. you dream on about your s28 mags....they are simply not made for heavyweight robots.....in the real world c40 300 are better than the s28. Equate that to the world of vapour then surly the c40 would be the better more powerful drive....add everything else i have said and your on a looser on every count.

good luck Mr Elam
