Sangsetia
« on: July 26, 2021, 02:58:45 pm »

I am struggling deciding what motors to put in this boat.The plan suggests two 540 type motors running with two 3 bladed navy props of 40mm diameter.I have two MFA 540/1 motors which to me look too small.I cant afford to go brushless so any suggestions will be very welcome.

HI What voltage are you planning on using? Are you using one E S C or two? What battery batteries are you using? The reason I ask these questions the motor is high revving at 12volts and I assume the stall current will be around 17 amps per motor.  The spec sheet for this motor is on the link below.

I think very few of us have modelled Sangsetia. Examples are few and far between.  Mine is still only "bath tested" after 15+ years!


I have two 777motors from the long gone "model motors direct". I think I fitted 40mm brass 3 blade generic raboesch props. 8.4v Ni-Mh batteries for power.  As said it's only bath tested and does draw a good few amps (I forget how much, but maybe not rediculous for brushed motors).  I keep on re-wiring mine as I had troubles with the original esc's and mixer.  I'm waiting for the combined 20a esc and mixer to come back in stock with component shop.


I know tendency these days is for the Colin McRae style of sailing, but from memory she wasn't that fast at full chat.


Sorry I can't be more help.  If I didn't have the motors already fitted for so long I'd maybe be looking at 5 pole 540 size motors, or similar to what you found.  It's reasonably big, but not a heavy model at all.  I ditched my SLA's for it very early on!


Not sure if that helps but keen to see another Sangsetia finished.

Hi is this the same model ? as the one that you are in the process of building.    If so, this link may just help you.

HI this is taken from the original plan so I would give a try. The ideal set up would be two ESC and battery for each motor.

I started building the model from the Dave Metcalf articles in Model Boats - haven't completely finished it but will try to find my photos of the build.
Took a few that might be helpful.
Motors - I had a pair of the Robbe geared units - 5:1 possibly, same as a lot of us were using in tugs.
Props and shafts - came from George Sitek, fittings - I ordered the parts outlined in the article from Caldercraft if I recall.
Had it in the pond a few times and a nice running hull design.
Will see what photos I can find - model is in storage right now but I can go and get new photos.
