Ok, that’s actually pretty good range :joy:

Could I ask the total amount you paid for the first board, Mr mcboardface?

23

Best I can do is based on my very fallible memory but I’ll do my best
Motors ~$360
ESC ~$300
Trucks ~$350
Battery ~$1200
Deck ~$220
Wheels $160
The gear drives were mostly free since @haven is a real one and all I had to buy was adapters and gears themselves which was ~$100
Both cases totaled to like $200
And the Megan telemetry display was the best $300 purchase I’ve ever made
Maybe $60 for tires
Probably just around $3k

Damn. Ok, good to know. Would you consider the parts pretty top of the line?

25

Top of the line is a pretty high bar around here to be honest, I have a board that feels very powerful to me, still blows every pre built board I run into out of the water in terms of acceleration, and will do about 40 miles of range at about 35mph. that said, there are people around here with twice the top speed that I have, you can buy a pre built from @skyart that does 80mph!

I really like my board and I think it’s great for what I need it for but I have a hard time calling it “top of the line” when I think of boards with more than twice my battery capacity like Bog Roosh or boards like Project Stop Resisting which are (with a skilled/potentially just insane rider) capable of doing 0-20mph faster than a Dodge Challenger hellcat with 700+hp

That’s a crazy top speed!

hey, top of the line is subjective! your boards are catered to your riding style, and that’s the important bit. what works for me might not pan out for youand visa versa. so long as you think your board is built to your liking, i’d call that top of the line :smiling_face_with_three_hearts:

After 5 years I think I’m barely starting to get it…

:joy: thats not very reassuring

3DS and BioBoards stuff is pricy…

SRB gear is considered good for racing…

Molicell makes good battery cells…

The more you understand, the more “top of the line” becomes clear to you.

It’s not strictly a question of buying the best parts and plugging it all in. The setup and build is a large factor in performance.

Look at the threads of builds nominated for BOTY, pretty much all of them use parts considered “best in class” for the type of board being built, but also are done in a way that makes those parts perform the way the rider wants them to.

Ok, thanks for giving some perspective.

33

What do you think of 6384 motors?

34

Depends on kv and manufacturer

35

Say flipsky, 170kv

36

Solid modors. Especially for the price. Reachers are better, Maytechs and Turnigys can be cheaper without sensors.

37

Ok, I’ll check out the reachers.

38

Do you think 2x 14ah 6s 12c lipo batteries in series will get decent range? I’m looking for minimum 8 miles, top speed 20mph, maybe more. Im definitely look for torque, rather than speed.

39

Depends on the amps used, which equates to torque.

This will depend on gear ratio, efficiency and wheel size.

Which will hang on your battery size. You’ll have 50.4v (assuming you put the 6s packs in series) and about 168A between (I assume) 2 motors, meaning under 84A per motor.

Check out the calculators available. There’s a great spreadsheet doc you can use that I’m too drunk to find the link for.

I’m looking at 72t to 16t ratio, I have 8 in pneumatic wheels from MBS.
