I already posted this under the “TB 40 deck” discussion, but decided to create a post to show you my new very long range machine.
Part used on the machine and cost related (without VAT/customs/shipping) :
Deck: TB 40 from Torqueboards ($120)
Enclosure: Bigben big enclosure from BigBen ($80)
Battery: 12s8p Samsung 50e (40Ah, 80A continuous, 160A burst), cells bought from Fogstar, and built by our Czech battery builder ($300 for the cells, $40 for the build)
ESC: Unity with Metr Pro ($255)
Drive train: TB DD 90KV from @torqueboards with TB 110mm Artic Blue 74A ($750)
Light: Shredlight ($100)
Telemetry: DavegaX from @janpom ($100)
Ok, I lied… He asked for CZK 1000 ($40), I gave him CZK 1200 ($47)
Yes I do feel the difference, they are plushier and grippier, I put only 500km on them compared to 3000+ km on the black ones, so I can’t speak yet about durability (I sold the black one to @michondr, he loves them I guess)
My bad, I thought the max burst was 20, 15 is still enough for me as I am lightweight (75kg with gears) and we don’t have massive hills like in SF in Prague, CZ. We have hills that are 15/20 degrees or more, and 300/500 meters long.
As my motors are 90KV, and not 75 or 60, torque is not strong from 2 to 10km/h, but after that, this thing is a rocket, all the way to 70km/h. So almost impossible to start a hill stand still.
Regarding the range, if the weather is good, I might try it this Weekend, but we are talking 5 hours non stop of riding at 30km/h… that’s going to be tough, but shall be done for science.
