Re: Question about capacity vs drain voltage

Of course, the battery would still output 22V and it would be the ESC that turns it into the right voltage hmm. My gut says this; If i run my ESC at 50% throttle and my motor takes 60A power, the voltage will be halved (lets say 11 for easy maff), but amperage stays the same. Thus, 11/22*60 = 30A lo...

Question about capacity vs drain voltage

Little thing has been bugging me and i cant seem to be able to google my way out of it :/ So, say a 2500mAh 3S cell gets me 5 km range. Now i want to increase the range. So i grab a 5000mAh 3S cell to get 10km. Thus far i still get it. Then what if instead, i take a 5000mAh 6S cell, i still get ~10k...

Re: 3D printed parts Depository

I'll let you know later how long this print survives (it's just 8mm thick, printed at 100% fill out of PLA) The 'tube' part that grabs the irregularities on the hanger has seperated from the main body of the mount. I have glued it with 2 component acrylic paint about 20km ago.. Total is now about 3...

Re: Fully Adjustable motor mount for Caliber

Awesome! Would love to see your Randal work :)
Will your eventual Randal mount work without requiring the hanger to be modded?

Re: Randal Trucks?

/me waves at newcastle.

I have considered casting it, but am not setup to do so :)

The plan has always been to get this model to someone to cnc it out of thick aluminium, and then get it welded on, the prints were just as test.

Done ~5km now, still fine, but i really need some loctite ;)

Re: Randal Trucks?

Starting to think i might need to use that included adapter plate to increase the mounting size, this pulley doesnt leave any slack ...

Re: Randal Trucks?

There is a upright 'notch' at a certain angle, which looks like a good candidate for gripping.

I'm not really against welding, just looking at something to use what i already have ;)

Oh hey, see what i just found; https://grabcad.com/library/longboard-trucks

Gotta see how well that matches up, but seems like a quite good model of the Randal R-II 180mm 50 degree Truck

Re: Cheaper ESC?

http://e0designs.com/products/hall-effect-sensor-board/ looks nice to upgrade a sensorless motor, but its easy enough to produce at home :)

Re: Cheaper ESC?

But what about reflashing them? I've seen mentioning of this happening, and for quadcopters, the most popular hack now just gets sold with some commercial compatible esc (and donates back to the coder)

Most curious about the Dlux ESC one i guess ...

Is there any reason to not run a 6S max ESC with 6S batteries?

Cheaper ESC?

So been looking at a LOT of esc's recently and its really suprising to me to see the massive differences in pricing... I have a 5055 280kv motor and want to run it on 6S so been looking at ~100A ESCs .. These options all look so very tempting ; * http://www.hobbyking.com/hobbyking/store/__16367__Tur...

Re: Randal Trucks?

Started on the moter end of things with just a 32mm mounting hole distance.

Guess i will stretch the holes up horizontally like torqueboards did, for easier tensioning. Although i am leaning towards making that diagonal to have gravity help keep the motor in place.
