Is your board 4wd?
Yep
Is that motor amps per side or total?
Looks fine to me. 4wd doubles the force so it is kinda ridiculous. Also average speed of 31mph is gearing for force, not top speed

Rough average of the 2, rear will will be 130a and the front 90a, that may change when its actually ridden but thats the plan

Assuming you mean averaged out that’s 110a per motor (130 for each in the rear, and 90 for each in the front) then yeah as @Shadowfax mentioned I don’t see anything wrong.
4wd is a beast in terms of torque.

Yep that will change haha. I’m running 110A in rear now and 65A in front and at the moment it’s more than enough!

7th place feels good.
1kN total board force.

Actually 1wd?
My commuter build has 280N, which won’t set the world on fire, but it can zip around an climb a decent hill. 240N definitely won’t get you to 35mph though, so you would benefit from gearing down to ~25mph.

Yea 1WD
Yeah I’d opt for a lower kv motor and maybe change the gearing to lower the top speed. You only have 1 motor anyhow not sure you want that high of a top speed with only one motor for braking.

240 N is not very good. The acceleration will be disappointing. It could still get you going pretty fast, but the takeoff speed will make you sad.
Save up more money and do a dual motor build.

Question… so 4WD boards, do you just enter in details for front and rear and add or is it not like that?

Yeah you could do that. Another way to do it is add up all sides and average it for per motor value.

If you have the same motor amps front and rear, there is a box to enter the # of motors / drive wheels, and you would just put 4 in that box.
If you have different motor amps for front and rear, yeah you would need to do the calculations twice and add the force from both to get total. Alternatively, just take the average motor amps. So if back is 80 and front is 60, use 70a as the setting in the calculator, and put in 4 under drive wheels.
