Another great video Steve, i really cant wait to see it all come together! Are we likely to see the car at round 3? Graham

@@rcraceandbash5472 hey Graham thanks for watching it! I am aiming for round 3, I'm not sure what state it will be in but hopefully will be able to do some runs 🤞 I have a lot of work to do! I Hope whatever you are doing for round 3 is going well. Funnily enough yesterday I was soldering connectors onto my lipos with 10 gauge wire using my Amazon soldering iron as per your recommendation 😀 it took max power but it did it nicely 👌

@rcraceandbash5472 15 күн бұрын

I can appreciate you must have a lot of work ahead of you. I only have two relatively simple cars and i worry if i will be ready! Glad the soldering iron worked out well for you. I had some goodies arrive from Mike at Onyx recently - he really is a great guy, so i spent the evening yesterday soldering 8mm bullets. Im hoping to get my 150 cap at round 3 and then go for the 175 next year. No doubt you will be hitting similar (or bigger!) numbers 🙂

The biggest problem people are having are the tires !!!!!!!! They blow apart at 200 mph

Nice to show the iterative design cycle. BTW, what CFD software are you using ? I know that it's a question of taste but is the background music ireally necessary ?

@steveeng1826 22 күн бұрын

@@peterfelecan3639 hi and thanks for watching, yes I've been excited to show the iterative cycle, in future videos I plan to show how it went because it's moved on a long way from what I showed here. Thanks for the comment on the music, I think some of what I've used worked but not others, I'll be more picky with where and what I use in future! Using Simscale for CFD by the way which is free for your first 10 runs (with numerical results).

The pointy tip of your design is very sensitive to the direction of the oncoming air. Consider rounding it more. Forcing more air under the car might also increase the Bernoulli effect below the car, but better validate CFD.

@steveeng1826 22 күн бұрын

Round it more when looking from the side right? I have been meaning to check the pitch sensitivity of my more recent designs but haven't got round to it yet. Maybe this week! Thanks for watching 👍

@Bengt.Lueers 22 күн бұрын

@@steveeng1826 Yes, it should be sensitive to bumps in the road. Rounding the nose more when looking from the side should fix that. You have got a nose like 🏎️ and you probably one want one like 🚗.

Youll need a solution for your wheels. You cant 3d print something that can spin at 200 mph without flying apart. Even car tires with reinforced vulcanized rubber and steel rims need to be specially designed for 200 mph. Check your Aero stability too. Are those tail fins big enough to keep you straight and will you flip up like a Mercedes at Le Mans when a little wind gets under the car? if you find your motors shattering magnets and bending their shaft JustCuzRobotics makes some hyper durable brushless motors for a premium but they're custom made to be high speed hub motors.

@steveeng1826 24 күн бұрын

@@Drawliphant thanks for watching, yes I'll be using off the shelf wheels for this car rather than 3d prints that should be capable of 200mph. I haven't got a way of simulating lateral stability so I'm going to have 2 sizes of fins and the option to have up to 3 of them! They are definitely necessary, I ran my old car without them once and it went all over the place then crashed.. I think I have a solution for getting balanced downforce front and rear but will have to see how it performs in real life! Cheers for the tip on the hub motors 👍 Steve

So wheel on motor huh? no suspension? Not worried about the bearings in the motor?

@steveeng1826 25 күн бұрын

Hey, thanks for watching it! Actually it does have an innovative leaf spring type suspension system of my own design, I'm looking forward to showing that in a future video. The bearings are a concern, they were on my first car too although they proved slightly more durable than the spindly 3mm motor shafts! The loading direction is better on the car than in a drone (radial rather than axial) and they have a 175kg radial load capacity, so I'm hopeful they will be fine! We shall see!

Yes good idea, I'll do this in a future video. Its fairly simple, just changing the mapping from memory.

I have an idea of what you might be planning, but im just going to wait to see it at rd3 lol. I was blown away by this car. And it was great to see you go faster and faster through the weekend.
