This was great. I would have liked to see another test with no aero and no windspeed checker. There seemed to be a bias in the weight distribution to the left side of the car which is where the wond speed checker was. Either way though this was incredible.
That's one sexy shot of the main man at the awards giving right there. Must have been filmed by a secret 'ex professional' video man thing 😋😂 Great vid dude
I have been doing reaearch wanting to get into RC drift. I was thinking of getting an MST RTR but the lack of upgrade stock has me concerned. I am currently thinking of getting the ReveD kit but was concerned as a beginner what sort of electronics to get. This video was the most helpful since it suggests some components to go with. 1 question i have though is a for a recommendation for servo brand. I have heard the stock one on the reve isnt up to snuff and i didnt catch amy specific recommendations in the video
Having a moving ground underneath is very important, you could make a two pulley system with a belt to place the cars on. As well make the length about 4” longer than anything you plan on putting on it. Hope that helps!
Is there any corelation between a completely non aero rc vs one with all sorts of modifications as far as handling goes though? It's cool to see aero "works" on that scale but does it translate to "real world" use case as far as RC is concerned ofcourse.
Yes, aerodynamics works at all speeds, the effects are just lessened, or different depending on the speed and what's being observed, conceptually it's pretty obvious the atmosphere is always present and therefore providing some effect to the objects inside it whoever told you otherwise is just misinformed. if you want an easy example of extreme low speed aerodynamics, hold a piece of paper up by one side on a flat desk or low friction surface and drop it, the curved shape of the paper will act like a sail and tend to slide the paper across the table, and it does so from an action that accelerates it VERY slowly, much lower than 10 mph.
It's pretty easy to find out what's the most downforce. The F1 cars from the 80's that used ground effect had the most aerodynamics and were banned because they were too good and going too fast. Just look up ground effect F1 cars from the 80's, it's basically a bottom plate that has sides that fall down onto the tarmac, which creates a vortex under the car sucking it down, that should in theory be one of the best aerodynamics you can get. Today's F1 cars use ground effect aswell, but not to the extreme extent they had in the 80's, they have alot more regulations nowadays to make sure the cars don't make too much downforce. It all depends on what you mean by what's the "most aerodynamic" , cause that can mean 2 things: either most downforce, or least drag. In terms of the 80's F1 cars that would be the most downforce, they had alot of drag so .. :) PS. great idea! and nice work! got yourself a like & a sub for the creativity :)
Dude, the laws of physics apply to EVERYTHING, of course aero works on RCs XD. Since everything is far loghter and smaller, the measurements are far lower, but they still have an impact nevertheless
One thing that scale RC guys dont get is that MPH @ Full scale or 10th it's all the same speed. It's a fallacy that we all fall into... MPH is a constant @ Any Scale or Size for that matter
not very scientific but its better than nothing i suppose for recommendations you should put a flow guiding mesh in front of the car and if possible i recommend making that smoke probe out of literally anything other than a cylinder as its not exactly a aerodynamic shape (could also try inserting it in an angle) those two should mostly fix your turbulent smoke issue and makes results more consistent i would also (as a viewer) recommend adding proper data sheets for example: 100g FL 100gFR 100g RL 100gRR at idk 10mph vs 15mph results the weight of the car specified in grams possibly angle of attack and other wing specifications etc...
On your Team Green. I wonder what difference the top spoiler makes at top of window. It gives neg pressure behind which draws the air down, would this bring more air onto the rear wing for downforce or would the rear window body line allow better flow over the rear wing? That would be an interesting thing to see as the Skyling has a cleaner flow over the back without one. Great vid
Is there a reason you are using a static car? A lot of the airflow is disturbed or at least influenced by the wheels. They create a lot of turbulence and distortion of the airflow when spinning.
If the wheel spokes were bladed, it could act as fans to create under pressure? It helps more with with drift cars i think because these wheels always spin.
Lets start with how awesome this is! Its awesome!🎉❤ I have worked in climate control for the composting industy for 8 years (now i have switched to machine engineering for 4 years). Airflow is a bitch! I always had the idea of building a windtunnel for my sleedrunner 200+kmph but as you said air is not scalable so making a diy 200+kmph wind tunnel is not feasable at home. Your concept is great! -Smoke machine with one small straw with smooth corners *Great! -weiging the car *Great! -Air flow fins before the fan *Great! -Funnel at the front and rear *Great! I know its hobby grade and you get results, thats great! But did you preform a control test on the tunnel? Without a car or anything else in it? To see if the tunnel itself doesnt create turbulance? It is possible you funnel in the front creates a small terbulance, it is possible that your wind guides at the end create different air speeds towards the fan. In the middel of the fan its connected to the axle and thats were the fan does not create air flow. I would recoment (if not done already and only if you want to) to make a contol test of the tunnel without anything in it. To make sure all airspeed inside the tunnel is the same. Than do a control test with the car in it and measure the speed everywere to see if the speed is all the same. Air can be compressen between the car and the side of the tunnel and air can flow faster there. en.m.wikipedia.org/wiki/Fluid_dynamics There is a small gif on this page showing air pressure arround an object. If the excess of pressure is hitting the sidr of the tunnel the tunnel is to small. A few things to reduce turbulance from the tunnel itself or betweet the car and the tunnel is to make the tunnel bigger. If you have done some control test and you decide to modify your tunnel i can help you redesign a tunnel.
This is a cheap and easy way to test out mods for my full size projects before spending a bunch of time and money fabricating on a real car! Brilliant!
