Let me see if I still have my plans from the Dumas kit. Sometimes you find these boats for sale on eBay or check RCgroups website. Dumas may come back out with this kit I was told. It was a fiberglass hull from Dumas.
Custom designed the radar tower from pics of real Sportfishing boats. Then used two Robbe gear motors which are no longer available but you can use continuous rotating servos. Mine runs on 4 AA batteries to get 6 volts. I also used white wire to run from the upper bridge where the gear motors are to the radar bars or arrays. Speed is about 24 rpm.
Ok ty if you ever see one built please let me know. I am trying to surprise my husband with one. He collects boats and has been looking for this one for awhile. His health isn't that great so I just am looking to make it happen for him. I appreciate you taking the time to answer my questions.
