Took a bit of a break from watching this channel because my car was breaking parts left and right so I gave up for a bit. But now I’m getting back into this stuff and ready to get back into this stuff

Best way to see how the car reacts and get it dialed in 💪🏾💯... Good Info brother!

My son and I are going to start getting into no prep rc and this was a very informative vid. Good job.

Slo Mo video is awesome and a great tool for seeing what is going with the cars. I can't believe that is an aluminum chassis, alot of flexing and twist. I used to work on aircraft and makes me wonder what alloy their cutting that chassis from. Hard to think that's 7075-T6. Short, sharp shocks through that chassis would eventually cause microfracturing. Possibilly causing the chassis to twist even more. I know we're talking a model car here but I was surprised at the amount of stress through twist that chassis exhibited front and back, brutal. Would be interesting to see a LCG plastic and the.Xtreme composite chassis videoed like this. This video was perfect timing for me, I had just looked at this chassis and an aluminum suspension "kit" on Amazon. What I had also noticed on YT videos of NoPrep was how many of the cars seem to launch good and track straight but still end up on their lid going end over end or some that seem to just suddenly barrel roll. In slow motion video I have notice a lot of deformation and flex especially just in front of the rear fender well and behind the wheel in the whole quarter panel. Wondering if that body flutter is causing drag and instability as the car picks up speed going down the track. Its lexan and it's going to build up air under it. Back half of the body flapping in the wind has got to be slowing the car down a little and even with the back cut out there's still air moving through the inside trying to pick the car up, that little bit of vibration might be enough to cause the car to become unstable and flip. So bracing the body seems like a really good idea. I am a noob to this, this video could not have come along at a better time for me. Thankyou!

Cool version for

Nice cars 🏁🏁🏁

The stiffer spring steepens the load change curve and will cause your tire to snap faster, causing loss of traction if spring rate is an isolated variable. It also changes the way in which your car unloads on take off with respect to the front end. It essentially changes the lever point.

When I ran my bo-link rc dragster we always tried to stiffen the chassis. I think that’s why most aftermarket chassis are carbon fiber with very strong braces. Great vid bro

Great info.

In real life we use dually adjustable shocks adjustable compression and rebound a must have for drag racing

You do not want rear squat you need to run a chassis stiffener and it's important to build a tunable chassis stiffener and it needs to mount on the forward side of the upper shock mount and run at least to the middle of the car the more flex or twist you have in your chassis the the less hit on the rear tires

Chassis flex and unsmooth road caused the front to wobble. Really not that bad all things considered. Those rear tires may get cut from that body hitting from time to time. Awesome video! Keep them coming, trying to sponge up the info.

New to no prep. Great info. New sub here!

The anti squat could be another thing to play around with as well 👍

I think this clearly demonstrates the weaknesses of the chassis itself. I think you are going to either have to go to a stiffer chassis or brace that one.

Love your vids mate. Do you have a part number for the rear wheels?👌🏻

I think the frontend shack was from the concrete not being totally flat. I use a 30wt in the rear shocks. seems to work for me

Please paint a white stripes on the front and rear tires so you can keep track of tire spin and as far as the wabbling it might be the surface that you're on try getting info on a smooth surface to start with ie finished and polished concrete works gr8

Front shakes because the rear tires shaking. play around with shock oils and shock pistons. Maybe diff weights or locked diffs

tried a top brace that maybe 1 to 3 mm longer that to shock tower braces to stop the flexing of the chassis at launch also a stiffer spring may not be needed try the chassis brace first then if the shocks are not compressing switch to a softer spring

Front end shake is "Torque Rattle" the torque is twisting the chassis, first to one side, then it twists back to the other side. Undo the Shock Adjusters. Just a little compression. if you can get the rear to start squatting, go to the softer springs. Try to stiffen the front of the chassis to cut down/eliminate the Torque Rattle going on.

I'm pretty sure the front end wiggle while carrying, Is also happening with body on but is hidden better from view

Love the video. Question. I'm building a 4wd drag truck and I really like the rear wheels and tires you're using on the rear wheels. What are they if you don't mind. Thanks sharing

Front end shaking could be the servo?

The front 'twitch' is the whole chassis at war with the motor.. the 'gyro' of motor wants to turn the chassis inside out the chassis fights back the gyro also loads one wheel and forces it to spring back which loads the other.. like a circle track car going loose or tight.

Awesome footage. Any recommendations for a no prep chassis?

I dont know the rules of the rc drags, but have you ever tried experimenting with adding weights to strategic point on the chassis to try to work through your problems i.e. the front end lifting and the flexing in chassis before shocks try to compress? Heavier can be faster if the weights are applied right. Just an idea. God bless.

My seem kinda rice or whatever but it’d be cool to see a fwd drag car build. I don’t see them often and with judging how well your no prep car has gone and your front engine dragster I think you’d be the one to do it properly

I went to complete fuel tubing in my front shocks and the top and the bottom half put a little bit of shock fluid in it and I run a 25 weight oil in the rear

like the videos man I wish had some good advice but I'm a rookie lol.. what kind of shocks are you using? thanks..

You should watch Street cars of the 707. All videos are helpful.

Could the front end see sawing be caused by the rear tires grabbing, then losing traction, then grabbing causing the rear tires to hop from side to side? I don't know what else would cause it... Do you balance your rims and tires? If not balance them and see if it helps These slow-mo analysis vids rock! Keep doing them👍

this is the whole point i make rc videos is to watch it in slow motion and to see everything flex and move and spin....

Could it be your anti squat? Does the kit have inserts that holds the hinge pin? If it does maybe that's the reason.

If there is a way to to make the side wall or you tire softer. Or an actual tire that already has a softer side wall you might be able to get a blue more traction because the soft side wall will simulate the low tire pressure that people use on slicks in actual drag racing. Having the squishy or soft side wall will make the side wall compress on the launch and put more surface area of tire onto the ground

I think that if these cars got 100% traction the shocks would move more? Even though it carries the wheels they still spin

Front swaybars should help the front wobble, IV seen it alot in 2wd sct races, the swaybar seams to help keep that under control, as for the chassis flex maybe you need a wheelie bar that attaches at the chassis instead of the dif?? Just my 2 cents, you can take em with a grain of salt bro

👍

Real cars do the same thing when they ride wheelies. Just have to try and keep the front down... Good luck . awesome content..

Where you at bruh? You got to be down da bayou somewhere!

Your front end needs to be weak so it will rise up and transfer weight to the rear so shocks will compress.

been thinking about drag cars, i wonder how a Solid rear axle would handle it? Maybe even locked rear diff, would put power evenly down?

What about adding a shock to the wheeliebar

Is there a difference between no prep and street eliminater

I think Pro-line needs to improve the body post, I like the plastic but I noticed mine were to soft as I noticed that right away when I got them. It causes the body to flop around at the high speeds with all the air hitting the body. But that's a Pro-line issue as we shouldn't be having to fix something that supposed to be fixed by engineers at Pro-line. I hope more companies start getting serious about no prep Drag cars, like they did with other segments of the hobby.😎🍺😜

Having no body on will cause that wobble since your chassis is flexing at the hit the recoil is traveling forward through the chassis the body is some what of an upper deck type stiffener per say. Just an opinion.

where do I buy this stuff, where do I get started, who do I have to throw money at for something like this?

Where did you get that red body shell and frame ?

soft springs help it compress , full scale no prep we run soft springs

Nice car. Is that a slash chassis?

Where can I buy the stock version of the car

Put spacers on the shocks

Definitely go ahead in change the rear shocks they are very very stiff making the whole car twist which is not good I think you will be fined maybe drop the oil wait to as well and the sharks

Need solid rear axle, independent gets the wobble.

Car transferring weight is a common problem with mid motor. Swap to rear motor an suspension will shift weight back better

Increase rigidity. Maybe aluminium arams and aluminium rear bulkhead. I see alot of torque twist on takeoff.

If your shock is compressing in the rear then think about the mechanics at work here if your shocks compress at the hit then you are loosing force that can be applied to your tires I think you spring and shock is good it's your flexibility that is hurting you especially after the hit

Could u build a dirt oval car

Great video do you have Facebook?

Do you sell those rc??

The front was wiggling because you shook the rear tires just a smidgen

Springs are too stiff causing the chassis to wobble.

The front of the car is twisting back and forth because your getting tire shake just like a big car on the street :( lol

Plastic parts are the problem.

Looks like it hits a different gear at about 15ft,,,,,NOS?... Lol

put a sway bar on the front end...GMO

You dont want compression, you want rear lift, run a sway bar and a softer spring if anything. Rear lift confirms the tires are planting, compression means the tires are trying to lift off the surface.
