This is my version of a RC car with instead of one motor and a drivetrain it actually has 4 hub motors (outrunner motors) one on each hub supporting the wheels.
I have done my best to explain everything but I'm sure I missed some important information, possibly a lot! so if you have any questions ask away and I'll do my best to update you and if I don't have a answer I am extremely sorry🙏
I was using a single Floureon 3000mah 30c 3s lipo and I got around 35-40mins going quite hard most of the time👌
VERY cheap 35A 3s esc
www.ebay.com.a...
VERY cheap 2212 1000kv motor
www.ebay.com.a...
The rest is VRX!
If you wanted to build one of these I would highly recommend using better esc and motors, this was just to show it works even on a very tight budget.
Please leave a LIKE, SHARE and SUBSCRIBE, feel free to leave a comment or ask a question and I'll get back to them asap.
Thanks for watching👍

What's up everyone😁✌ This car is 100% experimental and it definitely does NOT look professional but I will get it set-up with better motors and escs eventually👍 It's a bit of a beast already though🤪🤘

@oneglimmer Год назад

Joining multiple esc into receiver does not multiple them from 6-12-18-24 unless you physically wire each pos to neg ie series. Having an adapter with 4 joined parallel will just be 6volts at the receiver so no need at all to worry about overvolt as no chance of that happening. Great vod.

@rccrazy Год назад

Thanks! The main issue with the BEC in such basic electronics is that the voltage or more so the current is not always equal even on the same model escs. If there is a massive difference (probably 5% or more) that can cause all sorts of synchronising issues and unwanted resistance in the system. I would rather just remove a few wires than try and closely enough match 4 escs. Some companies do say its fine but I think you'll find their escs are very close to each others specs, and expensive😅

@willpeeler8547 9 месяцев назад

I was going to say this too. However you could do tank drive or torque vectoring if you program it right with 4 motor controllers.

@rccrazy 9 месяцев назад

It can be done with a DumboRC radio but it would look more like it was drifting rather than steering, I don't want it to look like it's drifting. It's got no steering issues just bad escs.

@PERTHWESTOZRC 2 года назад

Been waiting for this test run since you told me about this project, that runs sweet man, great speed in that tiny spot. Look forward to you opening it up on a proper straight road, should get close to 100kph I reckon 👍

@rccrazy 2 года назад

Cheers heaps man🤘😁 Yeah I had no idea it would have such good acceleration😅 I think you may be correct saying about 100kph on 3s, that would be awesome! 120kph with some 4s escs on 4s and I'll be stoked🤞 Thanks for checking it out man👊

i dont know if you went further with this project, but seeing as you have four independant hub motors, you could try the tank steering mode on that dumbo rc and steer without the servo. would be cool to see.

It is still together but need some better escs, but yes the tank mode would be cool to experiment with👍

@nathanburton2002 2 года назад

@@rccrazy best of luck with it mate I'm looking forward to seeing that, I'm "recycling" some 5s 2300kv race drone motors for use in my project.

@rccrazy 2 года назад

Ok cool, just be aware that many ESCs don't recognise 5s lipos and will start up as 6s and just hit low voltage really quickly. You can switch the ESCs to NiMh mode and run them if you keep an eye on the voltage, I don't think they have a low voltage cut-off in that mode. If you didn't already know that or are using 5s specific ESCs👍 Oh and if yours is direct drive like mine I probably wouldn't run that high kv on 5s or even 4s, my 1000kv motor get hot on 3s😬

@nathanburton2002 2 года назад

@@rccrazy good call mate thankyou I appreciate it , do you have any idea how you're going to solve the cogging problem yet?

@rccrazy 2 года назад

All good👍 The cogging I think is just from having only 35a ESCs, if it still coggs with 120a ESCs that will tell me the wheels are still to big (over geared) Running higher voltage will sometimes eliminate cogging aswell (less resistant I think and higher start-up punch) but obviously don't go over the recommended volts running direct drive like this unless the motors are like 300-500kv😅

@stas_robotmaker Год назад

Are the motor shafts durable enough? Won't they bend after a collision/some off-road driving?

@rccrazy Год назад

This will never be going off-road! Don't plan on crashing but the shafts are definitely strong enough for this application. I'm more worried about the motor magnets coming loose but no issues so far.

@addyshimov 8 месяцев назад

i wonder how good steering is and not messing with oversteer...@@rccrazy

@rccrazy 8 месяцев назад

@addyshimov well it didn't have oversteer issues it was definitely understeering due to the escs being so laggy. I couldn't afford 4 good escs to male it better so I just converted it back to a normal vrx cobra again.

@addyshimov 8 месяцев назад

so you mean with better esc`s the steering would be great - like diffs?@@rccrazy

@rccrazy 8 месяцев назад

@addyshimov really good way to look at it yes, but with the laggy/under powered escs it felt like diffs with water thin or ZERO oil in them😅 With well synchronised and powerful enough escs it would've felt more like having 50-60k oil in diffs and probably steer great and maybe even capable of drifting👌

I think outrunners a little more vulnerable to heat and damage compared to inrunners, I'd try and keep the temps down to like 80°C max, any more and you run the risk of permanent damage.
