sorry gary i meant fleetscale picture of bismarck build .take a look took it on water,for first time used my 1/200 bismarck as a tug towed the hull out then used the fleetscale hull to tow bismarck back.decided all was well and let it loose no problems encountered,heres a few snaps i will post a link to you tube later you can see for yourself.i used the electronize motors 35mm props and 6volt sla battery very pleased with results makes my 4 foot bissy look small bit excessive for a tug dont you think,lots more lead ballast reqd,20+kilo me thinks.
