[@ZeonicZaku1-Zeon_Grunt_Suit]

If you wanted the cars to actually go through the loop giving them an extra piece of track to travel before they hit the loop and adjusting the booster speed accordingly could've worked. They were jumping so much before the loop that they didn't have any traction so of course they all fell off the loop halfway up.

[@0vven]

why 69

[@TheCleverJoker]

Or just using a simple suspension pressure regulator to allow for less compression for to reduce overall speed gain.

[@C_Castillo]

The problem with the loop was he was sending the car against the arrows, not with the arrrows

[@chasr34]

a way to make the boosters that uses the MK 1 mody, make it so the wheel has a spring on it so it can go along the curvature of the hotwheels, giving it more friction on the booster, thus more boost

[@Akuma_Z]

Numa Numa guy

[@cobalt_3283]

easier said than done

[@stevenferguson351]

One improvement might be if you could adjust the speed of the booster wheel, so you know less carnage. Or possibly even more. Hot Wheels also has a playset with a Monster Truck booster. I've been hacking the playset so the monster trucks can go through a loop but not much power after that. I simply don't have enough Lego Technic. So many different hobbies.

[@BrunodeSouzaLino]

Other people have commented on the spring loaded nature of the wheels... They also have to be on the sides of the car low to the ground. If you put them on top or high up, you're losing energy pressing against the car. Also, some boosters have four wheels: two are idlers and two boost. The idlers help stabilize the car and make sure they stay on the track.

[@m1nor1ty30]

3:03 I like how you change the music lol

[@mattbatcraz]

I mean essentially these are how the Flywheel Launchers work, it was still neat to see how increasing the gear ratio effected the overall launch power.

[@FriendlyOne_]

I would suggest putting mechanism on a spring so that the spring would try to push the wheel towards the track resulting in a better grip of the car. Mechanism in the vid(1 wheel on top of the car) can only grip car's roof thus loosing momentum. This would also work if you can manage to do it with 2 wheels on the side that push inwards

[@ratchricane1971]

Dr. Engine really turned the Hot Wheels cars into lethal projectiles

[@Caldoric]

I have a design recommendation... Why have the wheels be 100% stationary, when they could be located on "swing-arms", allowing them to better adjust to individual car shapes? Either have the swing-arms pulled together by some rubber bands, or use springs to push them together from the outside (if you're using the two-wheel design). For the single-wheel design, a spring-pressed vertical swing-arm should keep things working well...
Actually, what of you swapped out the wheels themselves for treads/tracks, particularly ones like on the old "Manas", "Muaka and Kane-Ra", and "Tarakava" sets from early Bionicle (or wherever else you can find suitable examples)?

[@MattRevs]

Swing arms could be achieved with careful utilization of the shock absorber piece (76138)

[@altaccount4697]

That is a way better design. Only issue is if a big blocky car hits it and it bounces up when the front contacts and then misses the rest of the car. Lego doesn't make them, but compliant wheels are best for shooting funny shaped things. Source- FRC.

[@justapoet2794]

I remember having a hot wheels booster with various settings and I would always set the booster on max and the cars would just go flying off the track 😂

[@Ilyandroo]

3:10 Haha, it looks like the hot wheels track does not withstand high speeds

To get the speed you need for the loop I think it just needs smaller tires with spring tension from the side.

u can improve booster by speed or by adding 10 boosters like at the 2:47 at a row

Glad that after a few test you realise that the style of Thai abuses used on the old hot wheels meteorite set from donkeys years ago and the 2000s with the most optimal design and always will be the most optimal design for boosting cars it ridiculously high speed

[@robertbuth]

[@alolanstarboy]

I remember as a kid in like 2003-4 I used to have the Hot Wheels Zero G track set that basically used this exact technique just with two spring loaded rubber wheels that spun on the sides of the track rather than on top of it. They would be what rocketed the car around the whole track

[@jmeib]

Yeah, I know the one, I used to have it too

[@crvdr3619]

De hecho, yo tenía una pista de Hot wheels (allá por el 2005), que en realidad sí tenía un mecanismo similar, y usaba 2 baterías tipo "D", y estaba diseñada para dar giros y vueltas así como las montañas rusas, para que al dar la vuelta volverá a pasar por allí y se podía quedar en bucle la pista
(Nunca vi otra igual)

[@raizieldragon]

Anyone else ever so slightly bothered by the arrows going the opposite direction on the loop?

[@anousenic]

Me.
Also that's probably why the loop broke. The connecting mechanism was likely designed to withstand the forces in the other direction.

[@martinandrewdiel473]

Take note: the more gear you add the more faster it goes

[@OutrunRewind]

i have a very cursed idea
make a tracked or wheeled chassis (whichever is convenient) large enough to slap this on and now you have a gun carrier that shoots cars (as ammo)
