You would definitely benefit from tweaking the front to rear bias then!
Yeah that’s definitely the right way. But when you are at the point where you need to feather the throttle to keep grip, you need to do many launches to really get a good measurement of what’s possible. It makes hard launches much less repeatable.
When my board was 2WD and I put on exway race tires I was spinning out the rear not too far from the point of doing a wheelie, and that was around 1.09s. But that was at 85% throttle. Getting repeatable times was basically impossible. On the big wheels in 2WD I could just hit full throttle and do 1.30-1.35s with a basically flawless success rate.
I find on corner exit, with a balanced front/rear setup it sometimes leads to me spinning out the fronts getting on the power leading to a bit of understeer. Moving to a rear bias setup, I felt closer to feeling like a RWD board (no shit), but meant I didn’t have to put as much weight on the fronts on corner exit, instead shifting some weight to the rear to get a little bit more traction out.
In terms of brakes, I started with a rear bias (Atlas Pro’s only configuration) and noticed that in harder braking zones I would end up locking up the rears, with more braking power still technically possible from the fronts. so since moving to vesc I’ve moved to a front split to just get more power out of it and to stop fairly disconcerting rear lock-ups when trail braking.
But in terms of vibes, it did take a bit to get used to, but I’ve been learning to enjoy it. It somewhat helps with my riding style of pretty aggressive turn-in with the front trucks as it throws even more weight over it. Unfortunately, the additional force on the trucks in heavy braking does counteract it a fair bit, so I have to get off the brakes a bit more when trail braking.
Doing drag race pulls at track tonight with Reggie and @HAIRYMANJACK, I quickly was limited by spinning front tires.
At ya’ll’s suggestion I split up my power delivery; I’m running 130 / 160 front/back, -80 / -60 brake front/back.
Set some record drag race times, but confident I lower even more with more tuning and practice. This board goes through battery too fast
Wild how much of a difference lowering the front motors by 30 amps made. my launches got way more repeatable. Additionally, I get what you mean by this now
I was expecting the difference primarily at high power, but I was shocked by how much of a difference the split power made even at low power. I could feel the rear was doing more work then the front, which is wild. The board felt more predictable, more planted, less jumpy. Good things.
Continuing to do launches, with my front wheels not skipping, I can definitely put down even more power. Probably going to up the motor current significantly for future drag race runs. @poastoast@Skyart 6484 205kv 15s how much current to saturate the core? 200A?
I think the dip halfway through the pull is me chickening out on the throttle. @janpom is there a reason that ppm isn’t being logged in my data? Do I need to update something/turn on a setting?
There’s no setting but you need to have a recent enough firmware – v0.20.0 or later. Current stable is v0.19.2. We should release later versions as stable soon. You can also enable beta firmware updates in Voyage Connect under Misc settings.
Had an incredible time racing at TEF1 today. By far the best track I’ve ever raced on. I hope we get invited back, because it was blissful.
I qualified 3rd(1:34), behind @MarioChacon and @HAIRYMANJACK. However, in the actual races I was notable slower (4~6 seconds) to allow my legs to last all 3 laps.
Got taken out by @Ruxx in the final race, but hopped back on, kept going, and finished 5th.
Onboard from Dina behind us:
Checking my logs, we made contact at 32 mph(gps)
Max speed on the straights all weekend was 52mph(gps). should’ve pushed that harder.
All and all, such a great event. Really hope we can race there again some day.
