Hey Raz I came across your channel a while ago and I thought yes " Someone finally truly technical and is actually carrying out the process of science ( Or testing or bashing whatever)". The actual testing and thus results you produce are appropriate. You don't just "wing" it. There are clear inputs and outputs. Which is kind of what created this whole hobby of RC. This is my favourite video just because of what you were trying to accomplish. I appreciate the work you have put in. One engineer to another. The stuff you do is technically precise and brilliant. Thanks.
The editing on this one did have me questioning my sanity a bit. Great work as always, as I've said before, I think you are into the diminishing returns part of your quest to break the world record.
Just brilliant, so glad your ok, could have been so very much worse. Man that flare up could have damaged your eyes and you just worried about your friend. You are an inspiration to us all. John
I have a lot of respect for you Raz not only do you help us go faster sell go fast parts that are amazing by the way. But you show when things go bad to. Love your content man keep it up.
I have heard that the 6,pole motors are too much for the xlx2 over a certain rpm. Guess that seems true. Thanks for sharing your successes and learning moments with us Raz.
Beautiful, edited video was funny even the rc burn is not fun at all, thanks for the tip, now I understand that mistake, don't go beyond esc limits always under the limits esc, I appreciate that
Just had another thought. Maybe stepping up to a larger 5th scale or industrial strength motor will not strain it so much. A . 2 or 3 speed gearbox Would also bring relief to the system.
Wow, your cars look really technologically advanced. Just curios, it looks like you have some form of ground effect implemented into the chassis design. However, I'm wondering if you have full venturi tunnels integrated into the design as well. I see the splitter and also the diffuser, but don't see any of the critical tunnels or skirts. If not, this would be a keen area to focus on for potential improvement in downforce, cornering (in your case, not as important) and better straight line stability. This can be done all while achieving a lower overall drag as compared to wings and other body work aero elements. All food for thought in your quest for faster speeds....
Awesome videos thanks, Kindly if may could I ask you a question about the soldering because I couldn't get it right! What kind of soldering station do you use or at least the wattage and the kind of tip not to burn the connector? Thanks Joe
Dope video. If I were you I’d look into the neu 1533 2400kv motor. Mine actually spec’d out at 2200kv cuz of strong magnets but I’m sure it’s a 200mph motor maybe even faster. You won’t be disappointed
Something that may warrant research is motor rotor magnet strength. A weaker magnet will Achieve higher rpm and a strong magnet I assume will produce more amp draw . Maybe rotor tuning is a thing . Maybe a longer run up and a weaker rotor is the trick.
Hey raz you should look into express lrs its a open source long range radios system n i believe theres a way to use it with your futaba radio the range is crazy 13km + low latency its used more for fpv quads but also surface vehicles
Great progress to follow! But dude! Get yourself a small portable fire extinguisher and a pair of flame proof gloves for exactly these scenarios! With the money that's being invested in this attempt those items are a no-brainer to always have on hand!
Question, when you are doing these high speed runs, are you going both directions and then averaging out the speed to remove variables like wind/slope?
on the intro pass I figured you would have lifted when the car sounded like something was skipping or the car was hopping off the ground also on the one that burned, if you try it again, try speeding up perfect pass a bit. Maybe it messed with the throttle curve and tp takes perfect pass slower than castle
If you are going to run two motors I would just use a 2wd gear box and have one motor for the front and rear. It would eliminate all the propshafts, uj’s and bevel gears. I think some 5th scale onroad cars are 2wd. So just spin a rear gearbox and fit at the front and adapt brushless motors instead of the ic engines.
Just something to try by the way. Fill the inside of the body shell with polystyrene or something to fill the empty air space. Because the shell isn't completely sealed you'll be sucking air up and creating some drag
@@masonkaye5 but there is still air coming in through the wheel arches. With no rear on the shell it will still create some sort of air flow where you want none
@MaNNeRz Laguna you actually want air flow at the back of the body, because if you don't have air flowing there it causes turbulence which would cause more drag and instability because it would disrupt the air going over the back of the body.
@@MaNNeRz91 It causes turbulance, if you have no air being introduced behind the body it causes vortices, that is why the most aerodynamic cars try to funnel the air back to a point, like a teardrop shape. Examples of some cars that follow this are; aston martin vulcan, mclaren speedtail, koenigsegg jesko absolute, volkswagen xl1, etc. The biggest aerodynamic inefficiencies are the open wheel wells. Another reason more underside aero is not needed is because of the angle that the cars sit at, does not allow much air to get under the front end in order to keep the air going over the top of the body, helping the front stay on the ground.
If you’re still in Central Fla, I saw you had a Vape on the truck in one of your videos. I would love to volunteer my shop. I would also assert that we are the best Vape shop in Orlando.
Raz what about using the speed controller’s they use in Kayaks electric kayaks??? They can handle abnormally high cell count. They also can handle continuous high rpm. Just a suggestion it seems like you are at the limit of our technology i.e. speed controllers motors tires.
by yanking the battery wires you pulled the wires out of the esc and then they shorted the battery causing the spark and possibly damaging the battery.
