Typhon 4S motor better in a 6S when running 4S?

[Luke66]

So, I've got a T6S that I've decided I wanna just run on 4S. I've seen some guys on this forum use 4S motors in their T6Ss. Do you lose any power after doing that? Seems like a good way to shed some weight and maybe get some more power? Or should I just stay with the stock 6S motor. I wanna get as much power as I can on 4S for general bashing with a Typhon.

 

[StephenSchandelmayer]

For sure just stick with the 6s motor and gear up if you need some more speed. It'll run really nice with the 6s setup on 4s.

 

[Luke66]

Hmm. Already did that. Seems like theres gotta be a better way for more 4S power. The T6S seems slower than my Slash 2wd on 3S.
Maybe my battery isn't broken in yet or something?

What’s your gearing? If you’re only running 4s and never 6s you can gear up quite a bit before running into heat issues. But of course, always monitor your temps.
Also, bear in mind that the 2wd Slash has a much higher KV motor in it. Those are quite fast on 3s. I’m not sure what you’re trying to accomplish for speed goals, but you could always run 6s in your Typhon of course.

On an off-road/speed basher that exceeds 10lbs, you'll never get close to the same performance with 8 less volts than the system is designed for.

Fine for on-road speed runners that have gradual build up in gearing/amp draw, but you need the optimal powerband RPM (kV) motor for the voltage you're primarily using. The gray area for 4-6S flexibility is around 2200kV (6-8S is 1650kv), but you'll need an ESC buffer to run less voltage with more amp draw and increased motor cooling or only briefly running full RPM/voltage.

Lots of variables, I'd look into the 4268s (2600kV quicrun) from Hobbywing if you're going to primary use 4S (4278 ezrun-2250kV if biased towards 6S). I've run a few 6S packs down to storage voltage with it, just not wide open for more than a second or two sporadically ensuring the rotor doesn't overheat.

KV is your biggest hurdle when running on 4s. The stock motor is indeed capable of running either, but is somewhat of a compromise on either configuration also. I think if you want to commit to 4s, 2200-2600kv would be optimal. I would stick to the larger 40-42mm diameter motor also. The Arrma 4s motors are 36mm diameter, which I think is a stretch for even the plastic chassis rigs they're being used in, I wouldn't imagine they would do well in an aluminium chassis 1/8 TBH. Good luck brother!!

I’m running speed gearing ATM.
Not tryin to really accomplish anything, just wanna get the most out of my car

I’m planning on only running 4S for a long time coming (my charger can only handle 4S) so I may look into that motor

Alright. I’ll be on the lookout for a larger sized motor with round 2600KV

I run my TLR on 4S, which is plenty for how I have it compared to 6S. Now, remember I will not get a 6S performance, but after I tuned it, I am very happy. I post this a lot. My older buddy has the Typhon 6S v5 running 6S. I have the TLR Typhon on 4S. Yes, he will win in the straight-only race. We do technical driving, so off the line, turns, jumps, he is not winning unless I mess up. I agree with the guys that you need to adjust to get it there.

4S beast here

Is the BLX motor better? I’ve got one of those sitting around.

Oh, and I use that same battery. Do ESCs sometimes not get all the power out the battery gives? I’ve got a BLX185 in mine ATM.

I sadly can’t afford to get a MAX8 in my T6S.

Here’s a pic of my current setup. I could start a build thread if anyone’s interested.

 

[KnowAir]

I can't imagine there's much, if any difference between a BLX 2050 and a Firma 2050. I used a BLX 6s combo on 4s in my Tekno for quite awhile, worked well for me. I decided to change things up with a Tenshock 4274 2200KV and TC Torox 185 esc. I wouldn't say night and day difference, but the Tenshock (6 pole) does seem to pull a bit harder.. or, maybe it's the Torox esc? IDK.

 

[Luke66]

I’d bet the ESC helped a bit

I’m running speed gearing ATM.

For 4s you can mos def gear up some teeth on the pinion over the 6s speed pinion. Again, keep an eye on temps. But a couple teeth can really wake it up.

Alright. I’ll be on the lookout for a larger sized motor with round 2600KV

Why not give the extra pinion size a try? Extra KV would definitely be better if you’re really tuning your system for 4s, but just running 6s would be cheaper and a LOT faster. I agree with most here, and run my Typhon on 4s with the factory speed pinion. But hey man, whatever bloats your goat.

Yea, the speed gearing made the motor run hot at the track. I may actually have to gear down.

I’ll see what I can do with what I got now, and upgrade if needed later.

Hi. I agree, but I do not think there will be a win between the BLX 2050 and the Firma 2050. I like the BLX version mainly because it has a ribbed motor that helps with the motor heat and is easier to cool with a fan. I do not need a heat sink with those motors.

As stated above, I would run the motor on a larger tooth pinion and watch temps on the motor and ESC. I have a display to see both mine to keep a watch.

I feel you can get some miles with that ESC just testing pinion sizes on 4S to see what's your limit and temps/

 

[blaster27]

Nice Typhon. Is that new? .

 

[Luke66]

Had it for a while, I bought it new from @joostin420 , then I put some electronics I got from @Dan B. in.

I think that's what I'll do for now, thanks!

You did well getting it from Joosten420. I bought a few from him. My next car? Infraction 3s, or a UDR. . The 3s as I have a limited driveway. That way I can bash it here, and not to have to drive to a parking lot. .Do you think an Infraction 3s is a mistake?

 

[Luke66]

Naw, I like my Vendetta, I think you'd like your Infraction 3S.
But keep in mind, the 3S cars don't like to slide as much, more grip then rip.
