Try stiffer springs and running higher rake, so the back is higher than the front. This increases the area the air needs to fill effectively sucking the car to the ground with no added drag

That rear wing looks like it would create lift with its angle. Maybe take it off or angle it for more down force.

One problem I’ve noticed is when the ref reach a certain speed it spin out so since the wing is flat it can either create negative lift or positive lift, in conclusion the front isn’t griping toward the ground and causing the front to be light or less grip then the rear

It may be a bit late, but if you want to use plastic that can be heated and bent, but isn't too brittle, you could try sheets of ABS. I used it quite a bit in custom applications for car audio back in the day. We frequently used the 1/8" and 3/16" sheets. It's pretty tough but a heat gun makes it bendable and it will hold its new shape. You can sand the thicker stuff to a sharp edge if you need to, for aerodynamics.

With the same model, I put the bottom back suspension mounts on the screw hole closer to the middle. This lifts the back with can prevent the car from flipping over and I believe can make that wing off yours useful. Hope this helps!

You might wanna put some angle on the wing. I'm wondering if at speed that wing is producing a bit of lift and causing the rear end to spin out.

so basically the rear wing is flat sitting still, but I suspect the front lifts while the rear end sinks which would point the rear wing down to the ground slightly creating lift, thus spinning out, the rear seemed like it was a bit soft and low, so he's gonna have to either give that wing some positive angle or raise the rear end up with with some thicker springs/tighter. Either way its a mixture of imbalance in the overall form of the rc, with the larger battery, the foam wheels, the wing and the suspension set up as well as the size of the rc. I also suspect the rears are locked up while the fronts might have a bit of play to them with the silicon plugs so more power is getting sent to rear effectively pushing its own self into a spin.

Even without downforce it could still, in theory, affect handling. It could affect the rotational speed, so for example when it wants to swap ends on him, it's less likely. Pay attention to the wing design on his other speed build. Tall wing, no downforce.

You need to limit the travel of the rear shocks to keep the tire angle flat. When the car gets to speed, the rear shocks are compressed causing the tire angle to change. Also, put some weight on the front end to balance the center of gravity. However so slightly, most of your weight is distributed towards the rear which also adds to the compression of your rear shocks.

@TheOfficialOriginalChad

Жыл бұрын

What do you mean “tire angle”? This suspension has both upper and lower control arms… Weight distribution or “center of gravity” doesn’t matter a ton during longitudinal acceleration, as all the weight is shifted to the rear anyway.

In physics, an object always wants to have the center of weight in front of the center of drag, so if this car is turning round then it may mean the center of weight is in back of the car and somehow the center of drag is at the front. It can also be tire setup, so I think the camber and toe adjustments can be played with.

You can use a thicker (maybe 1/4") acrylic or lexan sheet. To avoid the bubbling, it needs to be warmed up slowly at the bending point. It will add more weight but it's definitely not as brittle.

Mine sticks to the road hard with the stock spoiler. I think you need limiting screws in the A arms for lower ride and more rear downforce. Also you definitely shouldn't have locked the diffs. Filling them with grease is the way to go. With white lithium grease on all the gears you might gain a few MPH.

I don't know if anybody has suggested this yet, but it could be the torque backing off of the two differentials. From front to back it puts a twist under torque, and then a backwards twist when you let off of the torque. Causes the car to spin

Having fun is all that matters kev, great video,

you need more down force on the rear, try bending the wing to keep rear end sticked to the floor, you are loosing traction and that's why the rc spins

Try using kydex, or delrin. Kydex is what I use for skid plates, holsters, mud guards and wings. Also try adding weight to the front. Will help plant the front to the ground for tracking and steering.

the rear wing is tipped back making the rear end float, when it swings around and goes in reverse the wing is causing the down force which is why it was so stable in reverse. also the "fast car" has fins vs wing so the back end cant swing side to side

Put a little wedge or flat plane under the wing to slightly bring the rear of the wing up, that should fix your rear end sliding issues when you reach higher speeds.

The diffuser doesn't create downforce persay but a vacuum underneath the car. You want the front end low as possible. And you want the diffuser to funnel the air to a more narrow channel at th back end o the car between the rear wheels. That accelerates the air leaving the back of the car and creates the vacuum that holds your car down. I learned all this for actual cars

Try lexan for your chassis tray. Your swapping ends might be to with the front and rear diff being out of balance in the load / unload. Try swapping / gears, also locking them up may stop it compensating for differences in the gears/ gearing

maybe also a cender diff would help keeping it straight. as power kicks in the waight should be more on the back wheels and with a center diff the front wheels would just spin a bit faster as the back ones to "pull" it straight. but i dont know if there is something like a center diff for that RC.

the reason why the car keeps swapping ends because you put silicone earplugs in the diff, which locks it up and you lose all of your rear end traction. if you want traction you need to go for really thin diff and shock oils, like 3k rear, 5k centre, 5k front and you will have plenty of traction.

its spinning because the rear is now heavier, so any left or right momentum spins the car, the rear fin stops the car spinning when it reaches to the front, because of the air flow. regarding the 203hp project, drag cars have a wheelie bar to stop flipping, and bigger rear wheels for more torque. Also would recommend, more foam on the wheels, and smaller rims.

U need taller vertical stabilizers with a wider wheelbase in the back and if you stiffen up the suspension it will resist the down force more and hold its angle

Absolutely love the little lathe for the tires...to cool

Toe in is better for straight line stability. Race cars use toe out in the front to cause the car to change directions more readily on the track

Not 1st

It might be because when the rear squats due to the body's downforce at speed, the rear wing you made will cause lift due to its angle of attack. That little guy was actually on the right track...smart kid!

Such a great RC channel! Get a rear diffuser on there and try round 3

Give it some rake(front lower than back) a diffuser and firm up the back end. Make diffuser from the plastic you made the wing from.

I'd recommend a cutting board for the underside since there ment to be abused and cheep. If you can get a set of tires made of gum rubber I'd bet they would serve well. Super cool stuff .

Ha Kev, I would definitely make a diffuser because with that you create a vacuum at the back of the car. the vacuum sucks the car on the road, I would also not make the suspension too stiff because then the car will bounce and with that you also disrupt a lot of downforce.

It’s to do with the wing you need more down force I tried heaps of different wings and the stock one was best on the wl an it has to do with the ground.the reason why the flat wing works good with the limitless is because it already has heaps of downforce from the body and has plenty of weight at the back but the wl toys is light

Cg forward helps, but that flat front shock tower might be causing a ton of drag at higher speeds.

HDPE is what I would use as the bottom plate, but it would require a stiffener. They use HDPE on Kayaks and coolant bottles, you can plastic weld it with a heat gun and you will be able to shape it however you desire.

Have you measured hub center to hub center front to back ? It might have a slight twist. Have you checked the diffs for gearing? You could have a mild overdrive in the rear in which you could fix by swapping gears i use tape on the tires in the same place aka flat facing foward hit the trigger they should sit roughly facing the same degree.

It could be the wheels being out in the open taking air. All those other cars have the wheels covered so maybe air is catching the tires at high speeds and making it twist

What I would do is get some cheap spacers so you can widen the track width. And add some downforce to the rear so it will stay more stable.

Inspiration taken from Le Mans (the film) attach some bits of string all over the car with some tape, blow air over the car and notice how the string reacts, you want the string to be as calm as possible off the back end of the car. If the string is flapping about like crazy means you’ve got rather dirty air which as there’s next to no weight for traction, could be the source of the instability

Any chance for some comparison between the Xo1 Infraction and the new kid on the block the Ftx SupaForza? Nice vid Kev btw

13:22 HDPE is the material you're looking for! It takes a beating well and is heat-bendable.

Center of pressure is in front of the center of gravity... Just tilt the wing a bit to give it some more drag (so that the center of pressure shifts back) and also some downforce.

Have you tried kydex plastic, like they use for pistol holsters? You can heat it and it’ll form any shape. They sell it in sheets so you can use it for anything.

It’s trying to plane What this means is that it’s creating a cushion of air for the car to glide on. The reason it spins so easily is because when you go in reverse it creates a vacuum that pulls it towards the ground. The way to fix this is create an air escape in the frame. Or lift up the back end. While also making the rear suspension very stiff. With cushiony tires to absorb the bumps.

Actually you can fit in lc racing lc-12b1 spring on it.. make it more stiffer, and 6mm x 2mm o-ring to differential cup to stop tyre wobble

The wing might be too heavy now, and the front is probably already really light. I think one of the main issues is weight distribution.
