As allways Daz your works simply awesome,leccy isnt my thing i have no clue about what you just posted but im looking forward to seeing this one go.This cat may be another candidate for scaling up for us gas guys  ok2.Still think the bow may need more slope to it for downforce but i know this is just the prototype and you will make any changes needed  ok2,she looks stunning as do all your designs.

Cheers mart,basically some serious leccy power,3500 watts in gasser terms is 4.6HP x that by 2,once setup right and alls well with the design it should give most gassers a run for the money,just not the run times LOL.
Will see how this 1 performs and i will redisn once i know what else will need changing,but this is the 1st cat iv designed and built so trial and error,then rebuild LOL

designing 1 wont be a problem,but would need the hardware,engine etc to build round as iv only built leccy  1s.
In fact iv got an awesome sleak design for 1 in my head.
im also looking @ designing and building gasser F1s and nothing defo yet but maybe teaming up with some1 to make thse hulls,got loads of ideas and designs and time just not the funding yet.
