Very surprised you even got a run out of the cone car, my Buri was such a scary handful I gave up after 2 attempted runs... Really looking forward to 2025 and Llanbedr.

I think the FC has an easier time of it as the car has wheels on the ground to give more instant correction, not like something flying. I put the ESC's under the plate to protect them in the event of a tyre blowout, but it did make them impossible to access which was not ideal! That will be improved in future 👍

Nice to see somebody taking aero seriously, I'm kinda surprised this hardcore analysis is not more common among the Rossa attendees. Seems like the prevailing strategy is more power (which I have to admit is not entirely unsuccessful!). I would be inclined to put the canards at or slightly behind the front wheels, perhaps them being so far forward is what contributed to reduction of rear downforce in that one analysis - that's assuming the CFD sim is aware that the wheels are a point which can be pivoted around. I think the holy grail would be front and rear canards, actively responding to load cell readings of the downforce. Having more downforce than necessary for traction is only creating drag. I would also want to have a throttle controller that responds to current speed (eg. from GPS), so that just enough power can be added to avoid ripping up the tires, without depending on a very nervous human finger to get it right. Not sure how much of this would be allowed by the rules though.... Another thing I find amazing is that nobody uses parachutes, mainly they would be helpful to prevent your expensive car from turning into a pile of bits when it becomes airborne, but they would also be useful just for braking in a run that ended normally, and save the tires a bit. There was a guy there one time (I saw in one of Kev's videos) who had a car with a belt-driven solid rear axle, I think that's the way to go. Not sure why people want 4WD or complex suspensions like double-wishbone etc. or even Ackerman-style steering, since you're not turning corners much or dealing with uneven ground. Okay, now that I sound like a presumptuous know-it-all, I better go and find someone else to annoy :)
@steveeng1826 15 күн бұрын
Hi, thanks for taking the time to write a comment, its much appreciated. I agree about the holy grail being active aero based on load cell reading of wheel load, I have that in mind for the future but I need to get the car working as it is first! Regarding the canard location you get an output of total downforce and moment around a reference point, from that you can work out the downforce distribution. I needed to put the canards as far forwards as possible to give it additional "front downwards" moment! Throttle control wise the holy grail of that would be some kind of traction control, another thing I have in mind for a future addition! Parachutes would also reduce the load through the cars speed controller, assuming that is used for braking. My strategy is to use a combination of aerodynamic braking, then the speed controllers, then the mechanical brakes to bring it to a standstill. If I run into issues with that then maybe a parachute would be the way to go. The belt drive solid rear axle car is Afxentis's, it certainly works well for him, his is close to hitting 200mph with it. It certainly goes with the sensible philosophy of "start with the simple"! Thanks again and why not try and make a car yourself, sounds like you have plenty of good ideas 👍

@@rcraceandbash5472 hey and thanks for the message! I think the splitters and spoilers must be helping, because you're achieving some high speeds with your cars without them becoming airborne! But the open wheels cars will certainly have a high drag coefficient, which means you then need more traction and power to drive it through the air especially as the speed gets higher (as per the science of speed video). It's potentially a bit of a vicious cycle type situation! It would be interesting to do some CFD testing on an open wheeler to see if the body setup could be improved.

@Weiun Ай бұрын
I once heard it said that drag wise, driving a car above 180mph is like driving a car through a fruit cake.... In my experience once you get to 80 to 100mph then aero really starts playing a part, which agrees with your plot well. Think many peoples experiences with duals and quads also agrees well with your plots. May well help those trying to push for 200mph on a single too. Mass, and downforce and the effects they have are factors that have to be taken into account. Many thanks for the video and discussion, it will defimately help in my overwinter rebuilds. 👏👏👏 I am NOT going to rewind any motors though..... 😂

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.
