its my SUSSANNA... the heavy duty auxiliary TUG BOAT..
« on: September 04, 2012, 07:06:29 AM »

Good morning all respected modelers.. last week, i got an order from one of the prestigious ship docks of my Nation, to make a full RC full functioning tug boat.. so i got ample of photographs of various tugs, many are not builded or used here.. so, i got a thinking to make a good tugboat.. so, i found one so interesting in its nature and shape.. so, i took some aspects from various tugs, and realized this one.. and result became so amazing.. the back portion of the tug is finished in such a way as deep V .. this gave me ample of stability even at very high speeds.. this one is 100% scratch built and from thermocol.. nothing is used here as extreme stuffs to complete her.. and after finishing this one i maled these photographs to one of the senior Engineer, and he told me that he needs this model personally, and adviced me as these types of tugs are used in various roles from trawling to towing.. so here i started from thermocol.. as i explained many before, think need not more about primary steps..
here you can see the hull is finished and by putty works.. the prop shaft is made of ball pen body with brass bushes at tips.. for long life..

prop was made of washers and nuts, and later i made hydrofoil sections over blades.. by using PU putty.. this makes the prop so efficient.. in all RPM range.. this combi is one of the ever successful, with 1000 or 1200 kV motors... now i use this combi in most of my crafts..

 now we can see the simple arrangement of motor and drive train.. can see the out runner motor is fixed on a heat sink, scraped from a power amp.. two windows kept opened in front and rear of bridge ensures cool air flow all the while.. the drive shaft is a 4 mm bicycle spoke, and drive coupling is from bicycle spoke nipples.. the machine is based on 7.4 volts..

i fixed blue L E D panels inside the bridge, to save battery... time of mission.. i love this craft so much, as this one is extreme stable, at all speeds.. so matured at low speeds, but changes its nature as throttle opens.. then she runs like a speed boat.. with ample of torque..
