The inside motor on a turn is working harder so it runs hotter. If you were making a lot of say right hand turns the right side motor will be hotter. I keep my motors below 60 C or 140 F.

Thank youf for your notice. I tried making turns equaly so ia can exclude this.
I am not affried of the temperatures now in general. It was quite cold when i was bashing. But i am affraid of hot summer days, where temperature difference can differ much more then now.
Run time was about 3 minutes. Telemetry (EagleTree V4) said, that peaks were about 220Amp for both motors, its about 110Amp per motor. Temperature 26 Celsius is very good result.

The boat looks great and seems to go very well! Nice work. I don't understand the need to rework motors to work with the wire drive. Once the motor is loaded and running nothing should change to affect the wire drives. A few 0.001" endplay on the shaft is part of the motor design and changing that will chew bearings up fast once the motor is hot. I can't make any sense of modifying a motor to suit any type of drive. Can you help me understand what your talking about? Thanks
Hello, thanky you,
i have two versions of NEU motors in the boat. One version is with free rotor axial shift, second one, rotor shaft is glued to bearings not allowing axial shift. On massive load axial bearings are pressed and there is need to compensate drive line temperature expansivity.
I have noticed, the bushing wears more quickly on motor with no axial shift.

Todays telemetry data. Still same config
I am quite happy with Nanotech 65-130C 5000mAh.

Hi,
here is my next video with one years old Nanotechs 65-130C. It runs pretty great, i think so.
Next try i am going to test with new props, X440 Tenshocks ALU CNC props.
I thing, Amp draw is quite low. Temperatures are below 40 degs. Celsius.

I am not quite satisfied with speed of the boat. I think power units can do more. I would like to order new porps i found on promise hobby. http://www.ebay.com/itm/brass-538-le.../140920070057?
Do you guys have any experience with these props? Are these CNC brass props? Do they fit my power units?
THX.

They don't look CNC and have 4mm shaft.With the same final picth I would stick with a better quality props like the Y537...you can use a KS brass tube for bushing if needed.Gill
GO FAST AND TURN RIGHT !

I have received props from link above and i have to say, they are bad quality. Absolutly not as hard as Octuras and badly drilled.
I would like to order new set of props. Do you guys have experience with this CNC brass props?
