To prevent it from lifting off, I learned from Raz Shifrin. You won’t need the front wings and to cut down the rear one to basically flat. You also want the car to be higher in the rear and lower in the front giving it a rake. I’ve had the car take off on me on the spektrum 6s electronics before, and since I did that I’ve never had a issue
Congratulations on meeting the goal and running that motor correctly.
🤔 running that motor correctly? Did I miss something?
Thought it shouldn’t run back to back 💭
Thanks matrix!
Hi Kevin. No you didn't miss something. You wouldn't be able to tell as I didn't share the data. How many back to back runs is relative to Temps. The power system is laughing on 6s. Could run continuously back to back.
Wow.......Dr. RC......this is a super fast RC car.......over 100mph.........Fantastic setup........I really like that.....So Cool.......Dr. RC.......Thank you .......all the best! 👍😎👍
Thanks Andy
Great 👍🏻. Sweet for ur first time too. Crazy. Thank you 🙏
Thanks Mo. It's really not me it's the setup that makes it so easy. I should shoot a video of my car from back around 2010 to show the difference.
Wow a real Mark Webber moment there. Great visual demonstration of how much space you need for the limitless.
More space makes passes easier for sure.
Congrats on the 100mph , keep in pushing now .
Yep. What speed next without jumping to max right away?
Congrats man 👏 , awesome work and well explained
Thanks Greg
Lower the front end and put more preload on the rear shocks. Have the front angled down and you wont need the front wings. Nice job reaching your goal!
Very true however I'm not so sure the extra drag from the front lips will even matter so much at these low top speeds.
@@RCexplained Come on, you have the bug now. 100 MPH is the gateway drug. Good luck with the new addiction 😅
Hahaha. Don't worry. Bug was installed decade's ago.
Love it!
nice runs ! I thought oh s#!+ at the end but you got lucky
Definitely got lucky.
Great work so far. Given your large viewer base I'd love to see you advocate safe practices like standing on a ladder. I'd be happy to provide advice if you want to go significantly faster. Radio range, shock travel, tires, and some other factors will be your next challenge.
Love the ladder for safety idea. I've seen this in other speed run vids but always thought it was for for line of sight, radio range etc. Didn't consider the safety aspect of it, definitly a good idea.
its not front aero that's the problem the issue is the rear spoiler pushing the back end down so its lower than the front the air gets under the chassis. droop the front end to 10/12mm then sit the car on a desk push the rear end down until the back is just above level with the front say +2mm then slip some plastic/stiff rubber fuel tube over the rear shock shaft to limit the rear squat.
Great videoes man! Thanks for sharing. 🙌🏻 hope the car is ok
Thanks Emil. Car is doing well, just some small scrapes and bruises. No big deal.
You might not need them without the GPS there, it's causing some drag/lift on the rear. You might need a ladder or something to stand on too.
That's true.
Nice
Lets see those data logs
With this setup you need on full throttle after the car pass you. They have more speed to offer.
we are geared correctly for 100mph. This gearing is way under geared to hit much more and that was the point described in previous videos.
How did you get your xlx2 to sit where the motor originally was? I have an infraction and its the same.platform as im told and it doesnt sit.flat because of.chassis angle
Designed and printed a plate for it to sit on. You can see this in the previous limitless video on the channel.
@@RCexplained nice thanks for the quick reply.
Very nice sir. What gearing on these run?
I'll have to check the other video again where we calculate the gearing required for 100mph. It's somewhere around 22P/42S.
Good job, just needs a bit of tweaking.
why are you testing in KM? instead of MPH?
What are MPH?
Hallo sir,my name is jack i have a problem with my power boat can u help me for get the solution ?
Specification boat
Lenght : 100cm
Width : 36cm
Tight : 13cm
Motor : 2 pcs 4092 1250kv
Esc : 2 pcs 150A Flycolor
Battery : 2 pcs 4s 14.8v 7500 mAh 90C
My planning is
At the First change the old esc to 2pcs ztw seal 150A opto HV and then
I will add 2 more batteries to unlock 8s of power per motor
What is your opinion ? will this get optimal results?
We’re at the 120-150 mph on 4s. Set for 100mph on 8s is a drag racing setup. We’re are you at located at?
8s 100mph is a subscriber setup.
South of Toronto.
@@RCexplained if you raise the punch it will be much calmer during the acceleration and easier to control. 👍
@@alterdcustomrc4512 punch was set to 30%
@@RCexplained its a very powerful motor try 75% to soften it up. It will still max out but a lot softer. You’ll have a little more control
Ya for sure it will be bumped up. I believe it works as a time delay with the throttle input. Very handy feature.

Hey James, I picked one up!
