RE: RE:
I have built a 8' scale WW II PTB. All the parts are 1/8" plywood. Fir was used for all the framing that does not show. I used Birch with 1 very good side for all the surfaces that show. It runs on a car battery & a Minkota 41 pound thrust trolling motor. The motor powers 2 SS driveshafts in SS 1/4" bearings. There is a SS thrust bearing at each end of each shaft. The shafts are driven by timing gears and a timing belt. Props are each 5 bladed, bronze, 5.5" X 5.5" of pitch. 120 watt dual channel amplifier with 8 BIG GM car speakers. 2 seperate RAM engine sound modules that increase volume as the rpms incease. ...........Sounds loud with ear plugs. Very realistic operation.
Scale of boat is 1/10.
HAS A FULL CREW ON DECK. Boat is set up as a " Barge Buster " with loads of 20 mm & 37 mm deck guns. Ballested to the water line, it weighs 80 pounds. I normally run it at 50 pounds.
I had Staples enlarge the 30" plans to 96"
Big models CAN be done relativly cheaply.
