Nice work!! Keep it up

Hi, I am planning on getting a 1/10 short course rc car weights about 6 KG I have seen videos and it's not very fast so also getting a bigger motor. The RC use 3S batteries and come with a 120A ESC and Surpass Hobby 3660 2600KV says on the specifications chart that has a max amps of 63A and Io of 1.5 A and running around 33K rpm on 12.6V, I was planning on get the Surpass Hobby 3660 4200 KV the chart says max amps of 100A and Io of 3.7A this on 3S 12.6V get over its 50K RPM limit by 3K rmp so I don't if that little exceed rpm will be tolerated or the Surpass Hobby 3660 3500 KV the chart says max amps of 92A and Io of 2.8A has a 44 K rpm on 12.6 V both motors has a max rpm of 50K, do you think the 120A ESC will do the work or increasing the KV of the motors would reduce the initial torque and current against the original 2600KV so there won't be any problem with the upgrade, that 4200 Kv is the more powerful in the 3660 size but there is also the 3500 and 3100KV so this is also and option, also mention that I can't change the ESC or the gearing so my only option on increasing speed is by the motor KV or maybe get a 3674 motor 3000Kv. Thank you for your time and great content.

I have this problem with my X-maxx

Do you think the Hobbystar 4985, 1650kv motor can be ran on 8s without damaging?

what if the cogging feels much stronger on my brand new Trinity 4.5 t and even stronger on my Dash 7.5 t but very weak cogging on my Trinity Kill Shot 13.5 t ??

What connectors r they.

I bet you do a killer Kermit the frog impression

I dont know how many times I've been called stupid when I stated exactly this.

Thanks you sir I read your discription and I understand

K

How do they take it to the next level?

The lower kv needs more voltage

The max current here is a theoretical value, ignoring wire resistance. The higher the KV, the more windings, the thinner the wire, the lower the practical current limit.

Tnx

Fantastic video as usual! I really like that you have been diving into the topic of Lipo battery technology lately. There's something to learn from novice to advanced expert. I'd like to request that you do a video on how to truly determine the performance of a lipo pack by stress load. I know you are very much aware that an ESR is not good for determining the performance of a pack, rather, the pack needs a full 10 second burst load (250A) draw. The recovery voltage divided by the number of cells multiplied by "100" will give us a 3-digit value we can use to rank each pack. I have only found ONE unit capable of doing this test, and it's not cheap, but maybe you have annother way to accomplish this task? Also, I am wondering if my iCharger 406Duo or 308Duo will do what your charger will do. I have searvhed for your charger, but it doesn't seem to be in production any longer... Has so many very neat features!

Thanks for the video but what about the safety aspect of each?

So if I don't have those jump pack I will carry a 3s lipo 😮

Where to get the 3d Modell?

So 2 pole is best?? Haha So you could put a lot more volts into it

Will you test any Povway packs? I mostly use ovonic and Povway, just curious how they stack up

Als wir Jugendliche waren, haben wir bei uns auf dem Land auch viel Scheiße gemacht. Wir hatten zum Beispiel einen alten Polo, aber wir hatten keine Batterie nur eine neuen Volt Block Batterie die haben wir dann mit Plus500 und minus verdrahtet und das Auto angeschoben. Also einen Push Start gemacht! Die Batterie hat ausgereicht, um die Einspritzanlage zu versorgen und das Auto ist gefahren

Battery temp?

Ummmm, have you ever heard of those small jump packs??

But i can literally see the regular battery connected😂😂 fucking clowns. The only thing thats good for is testing a single light if it doesn't blow up from the short.. stop posting bs.

Maybe a dumb question, but why is it considered dead between 70-80% capacity? Is there something specifically in the battery chemistry at that makes it unstable below that threshold? Otherwise, why would I chuck a battery that provides 15 minutes of run time instead of 20?

You are spot on!!! I had a 2850 kv tp power motor in my limitless V2 I had issues so I had to get a 1100 spcktrum firma 8s and I’m getting 123 mph 34 pinion 39 spur mamba monster x 8s esc

I got a 24v electric chainsaw that has a poor battery. Could I use a RC LiPo to run it?

That hot air intake might give you better gas mileage due to less horsepower resulting from hot, less dense air being used for combustion.

There are many wrong numbers

Great video is there a trustworthy lipo battery company with an accurate C rating that you recommend

I was just driving my 1/8 scale Truggy around my house the other day and I was trying to beat on it to check my pinion selection and see what temp the motor got to. I was hitting the breaks a lot and zipping up and down the road a lot at full blast and the motor temp was good, it got to 142 degrees but it was only around 60 degrees out. One thing I noticed though which I am a little concerned about was the battery was pretty warm to the touch. I didn’t temp the battery but I was wondering, if I lower the punch level in the ESC some, it should probably help keep the battery cooler, correct? It’s a Gens Ace 4S 6000MAH 130C battery

RESTING VOLTAGE.... Great video and info ...actually looking to buy some Hobbyking graphene lipos .... I fly 3d fixed wing with 6S 4000 mAh and 5000 mAh graphene lipos from HRB and Yoowoo i use Frsky Tx setup with a 21.5 volt low voltage call out every few seconds if it falls below this 21.5 volts....once this settles at this resting voltage for say 4 call outs over a 20-30 secs period or more....i come in and land. What i experience which i find very useful with Frsky Tx is you can set a DELAY for your low voltage alarm and this allows you to feel the voltage drops with certain HARD manouvers as it calls them out then stops as it bounces off the low voltage ... I like this method as it allows you to use the full capacity of the lipos by flying low and slow to allow the resting voltage to recover thus allowing you to fly longer...been using this method for few years now and really like it.

Awesome work.

How are you coming up with this formula? Are you using Ohms Law: V x IR or P = I^2 x R? Formula is very suspect without some sort of explanation as to how you come up with formula and 2500 constant. "Extensive Data collection" doesn't really do it for me.

I wind my own motors, as long as you make sure you re-terminate all the windings, It's perfectly safe and easy to do. Often times these motors are wound with solder through insulation/ lacquer. If not just burn off the lacquer. This video should have focused on how to do this safely instead of just trying to frighten your viewers into avoiding this procedure.

nice video! we produce this kind of NI-MH BATTERY PACKS！

I wish lipo companys could be held accountable for lieing to us.

I am curious to see if you try their new Rapid line. I have been having good results running them so far. Especially when you consider the price point.

Thank you man💥 Have you their newer Rapid range lipo 😎

Thanks for the info, can you show us how you did the test so its repeatable and acuarate? Im interested to see how you were able to run 105amps for 124.8 seconds straight. As always, thanks for your efforts.

We need you

Thanks, I learned something today! Good explication for understanding!

This is really good, thank you! However, how did you derive your formula? I would be very interested in seeing how you did it, especially the temperature correction. Thanks again!

I use fishing reel oil on my bering I've got hundreds of hours on my motor 😐👍

lol you bought en entire whiteboard for this video lol so much wasted space

You should add animation for better

I like your channel, but sorry -- locking your center diff is about the worst thing you can do for an off-road buggy.

@RCexplained I have a question. I am a Grade 8 student and I heard of a formula Curent(I) = Voltage / Ohms.... Is this different?

There is no such thin as waterproof. radio control. PCV, jahasss

k man what you explained how many nm of torque a 36mm motor generate per mm, which is 12 , do you know the number that a 40mm can motor can generate per mm?
