Aerolight

Almost worked out all the kinks - even with it being so large on 6s it can flip of backward and break so I have added a wheelie bar. Also suspension is new for better packaging and more damping (need to put the anti roll bars back in tho) I got 15 mins of driving before it broke this time - the 3d printed shafts the rear hub gears ride on heat soaked and melted - now redesigned to use lego 2l axles so it 1 stud deeper but should last longer. Also if I'm in the uk and imgur does not work anymore what is a better way of adding photos?

Been a long time since my last post but lots of recent updates (plus stuck in another country so cant work on it) Designed my own hubs, diff case and transfer case fully contained with bearings. All the gears are still lego or 3d printed in basic pla. The wheel cv joints are 3d printed to lego dimensions (for packaging) and the main drive line uses cada metal u joints). I'm using the same tyres as my last version- 7.2 inch traxxas summit tyres on constom printed rims. Steering is a geekservo and I'm using a flysky nb4 for the radio. Now here's the brushless part I started with a hobby wing fusion pro on 3s - which has a sustained power over 500w so I thought that would be plenty power for lego gears (also all axles are standard lego). For reference- lego buggy motors are about 5w and my last truck was about 50w. But after testing and a bunch of improvements, it's actually underpowered and the motor is the week link which I did not expect. But before heat throttle it can do about 15mph and spin all wheels on tarmac. So it now has a hobbywing max 8 on 6s which has a sustained output of 3000w lol. (600 buggy motors?) Only ran it once before I left (need to get better bearings and finish chassis). It now has much more power than most traxxas or arma cars and can pop standing power wheelies.still only lego gears and axles, just spinning as fast as a turbine (currently the driveshaft can hit over 100krpm (telemetry confirmed 106000 peak) idk how the lego can take it better than the admittedly cheep bearings but here here we are) Should be done next month - am I OK to link a YouTube video?

Some things I noticed: Next to the red bevel gear, there looks to be a 1 stage planetary gearbox half what is found in the existing motors, the bevel gears (and existing norms) mean side outputs but there are odd structures that could be a rear pass-through that would be better for awd mocs (though it could just be for LEDs 7 and 8) At the other end of the drive motors, there is a piece on the spindle that locks to be for encoding Internally the steering motor assembly looks to be somewhat separate so expect a tank-specific hub without steering in the future Not sure why but the bevel gears are off-axis compared to the motors so perhaps not planetary reduction? Not what I had hoped for but better than nothing, I had lots of fun when I was younger with the power functions era version of this (until the battery pannel clips broke)

If Lego produce significantly mor powerful RC they would most lightly shift to self-contained gearboxes and differentials, while Lego can be made somewhat dangerous now significantly more powerful motors would make exposed gears untenable both for safety and longevity (from Legos perspective at least). My guess (if it has good power) would be a combined motor and bevel box (and hubs) with proprietary outputs so they cannot; without non Lego parts, be connected to current technic drivelines. Probably just 0.x increase in voltage though.

I used 4 small cylinders with water for a l gauge "steam" train, 2 pushing the rods and 2 driven by a motor I hoped it would move realistically but was jittery even after removing all the air I think the problem was the rubber hoses, would like give it another go but I am out of cylinders

Surprised the suspension is not realistic, the whole build seems week too the whole front end flexes with steering (bad mechanical limits). The whole hybrid system is a simple motor charged operation idk why. I guess its all on Legos next supercar flagship now (fingers crossed for realistic duel clutch now they have the elements)

Seeing it in detail is genuinely making me sad, what could have been... I does look very unfinished and the design of the weights seems intentionally limiting (hard to integrate in something that spins) my hope for the new supercar is markedly lower now

The new hubs are weaker in some situations than the old ones as they do not allow for an axle passthrough. The shorter axle has been in my MOCs for years lol. The problem of braking parts has been reduced lots but still is a problem for fast rc, but the plastic melting is becoming a limiting factor now even with grease. I hope Lego adds elements featuring bearings in the next few years...

Been waiting for a system like this since duplo cant wait to see it in action. Just found the your YouTube, is this representative of the final product or still prototype. The motor seams comparable to a buggy motor on buwizz.

You really need two cylinders in series if you using pneumatics, pneumatics work with force unlike hydraulic which work with distance so the pressure would have to be constantly varying on both sides for stable steering without about 100 times a second adjustment it jitters all over the place and uses a ton of air. With two cylinders you can get a stable left right and centre for most mocs, if you can put up with 3 steering positions I managed to get a single cylinder system to work with a mechanical system that linked the steering servo and steering position driving the pneumatic switch, it worked well with a variable backlash but required an unrealistically large volume of air to work. I also tried linking two cylinders hydraulicly and driving one to drive the other but even a slight leak ruined the whole mechanism. There is a third party hydraulic pump you can get and is the best solution if a bit expensive

Almost identical MOC if you want to see the functions in action LEGO Technic PERSEVERANCE Mars 2020 Rover + INGENUITY Helicopter - YouTube

great scale love the choice of steering over drive, a case where a lack of realistic function is a good thing gears and shafts over servos. This set would be 10/10 if good price the wheel mounts don't flex too much and the tires are rubber, but I suspect the tires will be plastic due to there limited potential use + realism. If you where willing to bend the visuals It would not be too hard to give the wheels drive via shafts, but motorisation would lightly be too heavy for the structure as it is now

When I first saw it I though you had linked pics for a star trek moc by mistake, looks great like a cross between a bird of prey and an sr 71, all models should first be built in harlequin first i think there is some law. Hope it is successful

thanks they do sound a lot more impressive than then numbers suggest, super disappointed I could not get to 3k though even with a pre EU ban vacuum cleaner

can u link a video? they do sound like they run far faster than they do its a real disappointment when you measure it to me at least Sry did not mean to sound disparaging of other peoples mocs people have built ones far more impressive than mine just mine is optimised for rpm
