ok dudes, settle sorry to start controversy. i was a motorbike guy before i came into theis game, and from where come from 4-banger refers to a four stroke, maybe it's an australian thing. anyway, yes a four stroke produces more usable torque, with power all over not just in it's power band (i used to own a two stroke motorbike- never again!). hang on, better fix that- two stroke motor bikes are GOOD. don't get me wrong (i d0on't want to offend anyone else!), but i ride trail/enduro and it suits my style better.

that said, i feel a fourstroke will suit 3d work better as it can swing a more apropriate prop for the job.
