My daughter (12 years) wants a board so we will build one together - Quality time you know!
She want Pneumatics and she want distant (25 km.)
We will limit it to 20 km/h (12,5 mph) and it should be able to handel hills fairly good.
I have a set of Evolve AT´s with pullys and belts we will use.
It would be nice with some input on these things :
We need to find a deck that is a little shorter than the “normal” sized longboard decks, so it will suit her as a smaller person. She wants to be close to the ground so we are looking for a drop-through a a drop board. And it should be able to carry the Evolve AT wheels with caliber II. Anyone has suggestions?
Motor - what would be a suitable motor? We want to do a single motor board. She weighs around 40 kg / 90 lbs.
We are going to build a 18650 30Q pack. Thinking og doing 10s (so we can use the same charger) but wouldn’t 8s be ok with what we want to do? What are your thoughts on that?
The board will be set up for her so the battery, motor, bushings etc. should match her needs as she is now.
Today I went on my bamboo gt with one motor disconnected to get an real world idea what kind of motor I should aim for for this build.
In gt mode it did what it should. I had it up to 25 km/t and it did one of the steeper hils it needs to do ok. It struggle a bit, but with my daughter at half my weight it should be fine.
So now I know that a motor that size handle it. Might still go for a bigger motor and then limit her in kv, gearing or controller input.
Yeah… there are so many parameters that can be twerked so I can reach the desired performance in many ways.
When I did my test today with the bamboo I was not far from what I want and thats a 10s config.
I might want a slightly bigger motor, so I have to adjust some of the other parameters. Battery could be one of them.
I lost my Regular status so I can’t chance the headline anymore. Would have changed it to “The Daughter” build, as it has been processed under for last couple of months.
Anyway… the build is finished. I ended up with the following.
Deck: Honey Mini V 32 Longboard Deck
Battery: 30Q 6s6p
Motor: Racestar 5065 140 kv
Vesc: Focbox
Enclosure with switch and battery indicator prepared by Psychotiller.
Trucks: Evolve supercarve.
Remote: Enertion NanoX
Wheels: Evolve pneumatics
I first tried some rkp. but those with the deck couldn’t handle pneumatics, but the tkp can. I got 1.5 inch more room with tkp.
After some rookie problems setting up the focbox I now got it running just as we wanted it to.
It takes me to 20 km/h / 12.5 mph on flat ground no problem. My daughter hasn’t tried full throttle yet. We got a nice acceleration curve she can handle and braking that are forgiving.
It takes Her up pretty steep and long hills no problem, with made us both happy. I Hoped it could and it can - great!
We have the stetting likes this:
Motor max 20a
Batt max 25a
Motor min (regen) -20
Batt min (regen) 8
All in all it is a succes for us
We want to get rid of the evolve pneumatics and replace them with sixshooters to get a smaller wheel. I we just love the sixshooters.
