RE: Building a Hull
build a wildthing or similar i built a 30" version of the gas mono everyone is now building and i scaled the plans down from 48" mine has a.61 in it so id say make youres 24"to 30" and you should be ok.if you want the plans ill send them its a plywood build and its coated in slow set epoxy no glass its not needed.all you need to do is use some cloth on the engine rails to make them strong.also the joints can be done in the same way.ive also built the full size version for a weedy motor which is a lot of fun,heres a pic of my big one.
