I wish I could buy two, a pity I don't have it in Brazil

[@mansbfishing]

Nice👍👍👍good job master..🙏👍

[@phillipjacobson4457]

I was thinking of 2 t200 thrusters mounted on the front. right, left side. For steering . Turn one off go right turn off left go left. I want to do lake trolling at say 2mph. Maybe use the 20volt output on the dewalt 60volt battery for all day use may need a couple batterys I like your flip up design.

[@ggtr0nic]

the efficiency curve doesnt favor 20v supply ? these thruster are made for slow cruise...i suggest to use bixpy if speed is needed ?

[@phillipjacobson4457]

@@ggtr0nic I have been watching for Bixby sale. Yet to see a sale! $1100 . in my state I have to register it like a gas boat and pay extra fees. For any electrical add on motors. And put on I'd decals.

Maybe I should just get a hobie itrek but there I go getting exercise again.

Nice and simple. What's the battery capacity and how long could you ride with that?

[@ggtr0nic]

My lawnmower 42v battery are 150wh each, approx. 1h run time at 4kmh médium speed

[@TheSjh196]

Very cool I hope it’s easy for me to build .

[@Fiveblades]

Did you mount the T200 backwards on purpose ? If you turned it around, It could increase the thrust: - Thrust-voltage 4s16.8v : Forward max. 5kg; Reverse max. 4kg; min. 0.01kg

[@ggtr0nic]

good question... can you show me a picture/link about foward orientation ?

[@Fiveblades]

@@ggtr0nic The 3D weed guard (www.shapeways.com/product/DJCJCK3XM/t200-or-t100-thruster-weed-guard-rear) and the mounting on a ROV shows the cable on the rear. However the clip on kzbin.info/www/bejne/a4Svp5iNmrFmjq8 shows different.

[@ggtr0nic]

@@Fiveblades ok thanks... in te SUP video , they use the same orientation as me : motor case foward

[@elisamiller492]

AWESOME!

[@flychip4001]

I just ordered on to put on a paddle boat., how did you build the speed control? do you have a Schimatic? I fly remote control airplanes so i have battery's and i ordered the esc for the thruster also.

[@ggtr0nic]

my latest version used a RC car remote ... foward/reverse would remove speed span precision so i made it foward only

[@FL-gg4dq]

The t200 is like 200 bucks . Wouldn't a trolling motor be better?

[@ggtr0nic]

MinKota 30lbs trolling is too heavy and require way more energy , brushless motor has 75%+ efficiency while brushed less than 60%...

[@Andy-df5fj]

@@ggtr0nic Although you are absolutely correct on the weight cost, you're overlooking something on the efficiency. Yes, a brushless motor is more efficient than a brushed, but that's only one factor. The bigger factor in this case is prop efficiency. The bigger and slower moving prop of a trolling motor can produce the same amount of thrust as a tiny T200 with far less mechanical input power and that difference overwhelms the motor efficiency advantage. Take a look at the numbers. A T200 produces 5.25 kg (11.5 lbs) thrust at 16 volts and 24 amps (384 watts). A 30 lb thrust trolling motor produces almost triple the thrust with only about 360 watts (12 volts X 30 amps). Basically, the small thruster is wasting far more energy in creating turbulence than a trolling motor does.

[@ggtr0nic]

@@Andy-df5fjagree : the T200 will loose efficiency at max output while giving better result at 100w or less...done my test with Minkota 30lbs 4 years ago : kzbin.info/www/bejne/iHm4Yn6ghZaXd5Y

[@Andy-df5fj]

@@ggtr0nic I bought a cheap chinese brushless thruster that was advertised to produce 5kg thrust, but that was a lie. It's more like only 5 lbs at 20 amps and 12 volts. Unacceptable. I'm currently in the process of modifying it to try to improve the efficiency. If I could get 7 to 8 lbs thrust, it should be plenty for the kayak I want it to power.

[@skyak4493]

@@Andy-df5fj Thrusters are for maneuvering. The thrust they list is likely a maximum at zero velocity. A 14 ft kayak would do over 4 mph with 5 lbf thrust, but that little thruster produces very little thrust at that speed. Motors with larger diameter props accelerate a bigger column of water, so it takes less velocity for the same force.

[@BassFishingFacts]

did you have to set the rudder a certain direction or did it go straight? I've been wondering if you could get by with one motor vs two. Only two directional, right? Front and back.

[@ggtr0nic]

side thrust doesnt impact direction much , compensated by my rudder... motor can go foward+back to allow seaweed removal...might need two of these if you want to run more than 4kmh... you might want to consicer Bixpy thruster if you want speed

[@catamaraninfo8413]

Super!!!

Hi, how much did it cost u ?

[@ggtr0nic]

300$cad thruster + esc ... 200$cad mower 40v pack + DC converter

[@rico3696]

Hey, did you use the T200 with more than 20V?

[@ggtr0nic]

no : i want to use my 42v mower pack with a DC/DC converter down to 12.5v .... this motor efficiency occur at less than 20v , approx 80 watts + 13v is the sweet spot for its efficiency ? efficiency graph are avalaible at seller website

[@herskerhans]

@@ggtr0nic which DC DC converter are you considering? I want to use my 48v bike battery packs for my T200 motor at 12-20v.
