The bulkheads where cut out early in the refurb, I wanted all the heavy work out of the way, they where done with a dremel, series of close cut small holes, then a cutting drill bit joined them up, and out fell the bulkheads! tidied up with a sanding disc on the dremel.
Paint, I would rather not recommend a brand, I have had endless problems and setbacks with the painting process, except the grey which was mixed for me, using the correct bs631 grey colour.
it has been done with aerosols, the job has been made easier by reconstructing new cabin tops, wheelhouse roof etc with plasticard. We also made a pair of plasticard sides and epoxied these over the wood sides, this means easier to paint, better finish as no wood to prepare, and all the windows are the same size, parallel, and same height. THe front wheelhouse was also rebuilt with plasticard, and the window frames made of the same.
My esc's are from hobbyking, turnigy 60amp reversing. not like yours though
Not sure what you mean by rubbing stakes, I think its the spray rails, I learnt with my 3 footer these are real critical, I used 3mm square plastic section, EMA model supplies, as they where the only people I could find that did 1m lengths, so no joins. On testing the boat handles very well and sails nice and flat, my smaller fireboat handles terrible in comparison with very excessive rolling on turns, bigger spray rails will sort it when I have some time!
