    Hi 👋, I am a old dude that used to race radio controlled hydros. I’ve done electric cars as well and buggies and I’ve written a motorbike a Harley Davison for best part of 30 years., and because I’ve been out on the road itself, I believe your find that your car park is got small humps in the tarmac, probably not noticeable to your eyes, but I bet if you laid something very long and straight across the area, your noticed those dips in the tarmac, when I have been riding on the road, you can see where sometimes lorries have bounced on lamps similar to what you’ve got, and these are funny tire marks, and this is the reason why you’ve got traction, no traction traction and no traction,
    Good luck , Phil from the moulin France,

    Hey Roz love your videos where I found that work best for drag is locking the front diff scorched RC Locker and 2mil in the rear what you want to do is get the front tires to pull and not let the rear tires push as the motor creates torque you need to adjust suspension for that so it actually keeps the two front pulling tires on the ground keep in mind you're trying to pull not push you will find you don't even need that wheelie bar it will just shit and get try and keep the car as light as possible add anything that is not completely necessary!! Power-to-weight ratio also you don't need such big of a milliamp battery you're going for a two-second burst you don't need a lot of gas in the tank just a high discharge hope this helps good luck

    @steveblackbird Год назад +6

    Epic video Raz, I think your wheelie bar needs to come up and be matched to your suspension travel. When the car squats the wheelie bar hits the ground taking pressure off the rear tyres limiting traction. Lift it up a little and you might see the skipping minimise and have a bit more traction.

    I love all the tips people give to setups. It’s interesting to learn from others and adopt different setups. One of the best tips a person gave me was play with your setup and do one thing at a time so you know what characteristics have changed for either improvement or failure. It’s a hobby. Take your time and play with your cars.

    Hi Raz. Love your content, and I admire your dogged perseverance regards everything you do. I was thinking the "hops" may possibly be due to an uneven surface of the bitumen.

    Raz.
    When you put the preparation on the road push the car through if but lift the car up to bring it back rather than pulling it back, this should cover more of the tyre in the preparation.
    Or you could try it in your workshop using just a wheel and some wood? 🤔👍

    I wonder if the drag bar being on the ground is causing the hop. I'd imagine the car compresses when you smash the throttle, driving the drag bar into the ground and potentially causing a rocking back and forth between the car and drag bar. 🤔

  • @L2theWcarscoffeelife
    @L2theWcarscoffeelife Год назад +2

    Question the faster you go do you still prefer a fast steering servo? To me I would think a slower one wouldnt be so twitchy at high speed but it seems everyone still runs a fast servo. Wheelie bar shouldn't drag its there to keep you from flipping over. That said you are all wheel drive so its a balance to keep the front end down as well so you have traction. Most all wheel drive cars will have 60 percent or more to the back tires maybe via slipper clutch or something you can spread more power to the back so the front end coming up doesnt cause tire spin. I think you should look into making your own brand of speed rated tires there is obviously a market for it .

  • @04toys
    @04toys Год назад +6

    You have a couple of things you should do. Raise your wheelie bar according to your rear suspension travel. Your rear springs should allow for some travel. I know you think your top in needs to be turned up but it’s actually too high so turn the last number down. Turn the torque down and gradually go up as you get faster. The key is to keep traction. When you spin it uses more power so you think it’s going faster but it’s not. So turn the power down.

    Hey, raz real drag racers put chalk on the wheel of the wheelbar. It will leave marks on the road where it touched. That might help the prep is supposed to burn out on a test run. You don't really want too much liquid on the road or the tires. Do a burn out first with the prep. Then put your car on the starting line. And go for it.

    I'm not an RC drag racer but I do drag race my real cars. My first thought into getting better times out of your RC is why not use real drag car winning formulas? Like wider tires, adjusting the suspension to let the car weight roll to the rear of the car, maybe developing real drag tires that squish / krinkle zones to help the car get traction

  • @marcoshuerta8661
    @marcoshuerta8661 Год назад +1

    My guess is you want the Willie bar little bit above the ground because you want your rear suspension to be able to work. Your suspension should be able to squat when you take off and then progressively grow throughout the run. If you're bar is touching the ground already it's stopping your rear of your car from squatting giving you aggressive acceleration off the line. All that torque is pulling that rear suspension down and all you're telling it is you can't go any farther down, so okay it's going to start spending because there's no more room to go down.
