Infraction I would like to know if the castle 1717 1620kv is faster than the 2200kv V2?

[BryrcNite]

Which engine heats up the fastest in a race?

 

[LibertyMKiii]

To clarify you are comparing the 1717 1650kv
Size: Diameter: 1.87” (47.6mm) at fins, 46mm at can. Length: 3.35” (85.1mm) ; Weight (w/wires):, 597.6g (21.08 oz); 548g without wires

And the 1515 2200KV.
Size: Length: 75.4mm. Diameter: 40mm (41.4mm with fins) ; Weight (w/wires):, 426g (15.1oz) ; 380g without wires.

How long is the race? What type of race?
What ESC is powering it? How heavy is the RC car?

If both cars are trying to go 100 mph and both run 6s the 2200kv will get hotter.
There is an ideal motor for an specific use case but regardless the 1717 will run cooler in most scenarios because of its lower KV and larger surface area to shed heat.

I have a mugen gt 1/8 and a limitless, the track I want to use is an autodromo, a track of approximately 1000m², a track with very few curves

What cell count do you plan to run
What is your target speed?
How many laps?

I think 150mph, I have a new 6-cell battery, I'm thinking of buying an XLX2 but I don't know if it's necessary for these engines.

IF you are thinking 150 mph the XLX2 is absolutely necessary.

Do you have a picture or google maps image of this track? I don't think you can run a car like this over 100 mph on a track and still make the curved turns if its the same as this other one?

If you need to run more than 1 lap at high speed then I'd say you need the big electronics to stay cool. XLX2 and 1717 or bigger.

Motors. Engines are nitro. . Its fun learning,as I am learning all the time.

With the 1717 1620kv can I reach that speed?

 

[Dales396lt4]

How does the 4990 Hobbywing compared to the 1717?

 

[LibertyMKiii]

Yes

How does the 4990 Hobbywing compared to the 1717?

I have not compared the two in speed run use, but I know that bashers often compare them as similar for power and running cool.
I have the Max6 combo 4990 in my XL Kraton basher and its great.

 

[blaster27]

I went with the standard Spectrum 160 amp system. 8s. But I have no need for anything faster.

 

[Garcbomber]

Considering you can get the HW M6G2 Combo already BT capable for a little more than the Castle motor alone, I'd say it's a no brainer.

Will go 100mph all day bashing in a road car.

Yes that price point of the Max6 G2 combo sold me on it.
I watched a video yesterday of a limitless going 126 mph with the ESC so its got big power...

 

[morrjr71]

I can attest to how cool the Castle 1717 1650 runs: I have one in my Kraton 6s, powered by a MMX 8s ESC. I can run over twenty minutes at full throttle in eighty-degree weather without the motor getting over 140F. If I didn't have the Castle system I would think seriously about buying a Max6 G2.

 

[Dales396lt4]

I have been running the Max6g2 4990 combo for some time in my Felony. I’ve always wondered if I should’ve went with castle. I’m very happy with the power This combo makes. I also run the max 5G2 hv and 4990, in my limitless. I’ve been 110mph with it just don’t have a good enough road to run it any faster. I’ve only made three runs in that car.

You want to go 150mph on a track? That must be one hell of a track…

With the 1717 1620kv can I reach that speed?

Sure, but you’re leaving a TON of information unsaid. Why in the world would you gear up for 150mph to run on a track? I just don’t understand.

Must be Talledega.

That is why I had lots of questions to clarify the use case.
Never seen anyone take a turn over 100mph

the track I am going to use has a straight where they are near the pits, that straight is 780 meters according to google maps, will it be enough for 150mph or will I need more track?

So its all more about what radio you will be using
