Puller Pro Brushless 4 pole Rock Crawler motors- Lay down the Power!

[JohnRobHolmes]

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

Silly question.. anything in between a 3500/4500 planned or is it not needed do you think?

How would you feel about a 4500 / 3s combo in a bomber if geared low enough?

We have some prototypes in a middle kv range, but they are just protos and may never become available product. The existing kv ranges are tuned for maximizing power on lipo battery voltages. Many people run the 4500kv on 3s in rock racers, your gearing will depend on battery and esc temp more than motor. There is no need to gear down otherwise. The 540 will push most rigs past 50mph with minimal heat.

I have a tech question regarding the Transmission Gear Ratio (TGR) for the Yeti 1/10.
I am changing stuff because the rig is now heavy and I went down on kv (2100) and up on the Volts (4S).
I'm trying to find the right gearing and so I need to calculate the FDR and hence the TGR.
HH mentions 1.92 while Axial mentions 5.67. From what I read, the TGR = ratio between the diff gear and the inner gear. So for the Yeti, I would come up with (27/15) = 1.8 for the Yeti.
But, HH multiplies that ratio with the High Speed Transmission Gear Ratio (28/26) which gives 1.92. Axial takes that value and multiplies it by the Bevel Gear Ratio (38/13) which ends up with their 5.67 value.
Who is right? Which number should I use when calculating the FDR????
Anyone can help? Thx.

Safer to use axials numbers. Don't get too hung up on numbers though, it is more important to monitor temperatures and tune accordingly. Run it, judge wheel speed , check temp, regear, repeat. (Old kv X 0ld voltage)/(new kv X new voltage) will give a general idea of any ratio change needed to keep similar speed.

Will do.
Thx.

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

Need some help. I currently have a Tekin RSX and Tekin ROC412 on a Mattzilla U4 1.9 rig approx 9lbs. Currently have the Dinky split skid setup.

Want to switch to a waterproof ESC so looking at the Castle Mamba X.

I plan to mostly do rock racing on this rig with very some trail running. Should I go 2700KV or 3500KV? Always run 2200Mah 3s batt here.

Thanks for the input

3500

Recommended ESC to go w/ the 3500 Puller Pro in a Yeti RR...obviously on the HH site, they have the Mamba Pro and the Trailmaster BLE...any particular reason to pick either of them? I'll do mostly bashing with a touch of light crawling (def not competitive). I'd be running 3S and want it to be fast for bashing, but controllable. I just don't know what ESC to pick.

The BLE has a "quiet mode" frequency adjustment that stops the annoying whine / ringing sound.

I run and love both.

Guess that's the advantage of not having a fan too. Any issues w/ heat on the BLE, running 3S?

All I run are 3s, currently I'm running a Tekin 17.5 with the BLE and it runs all day long cool and smooth in my R1

Update for y'all , We will have regular 3500 kv XL in stock later today, and waterproofed after a few days.



Anybody want slower kv choices? Looking at adding one more Kv to the stubby or standard size.

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

Lower kv options for an even smoother start up? I'll have to really look into what small 6s options are out there. 1500-1700kv on a 6s would be exciting.

 

[JohnRobHolmes]

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

Won't improve startup if the motor rpm is the same. Just for people that want slow, but don't want brushed. Or maybe you want to run 6s and 2200kv is too fast.

I buy Puller Pro 540-3500 KV and Trailmaster BLE Pro for my Grave Digger,what is de best lipo battery use with this 2S or 3S?

 

[JohnRobHolmes]

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

I would suggest 3800mah 35c rate at minimum.

I'm thinking about a PP for my SCX10 II. I'd like to stick with 2S lipo. Rig is for crawling and trailing. Smoothness and crawling ability is my main concern. I have read in this thread that the 3500 standard version is a good all round choice, but would it be too high a Kv for my application? Which version would you recommend in my case?

And just curious, would the stubby 2200kv or standard 2200kv give a smoother startup? (If indeed there's any difference at all...)

Re: Puller Pro Brushless 4 pole Sensored motors- Lays down the Power!

Got my BLE and Puller Pro installed on my Wraith and running great! Have a question about motor direction reverse... My initial setup I was using Motor rotation in "normal" and my Futaba 4PV also set throttle reverse to "normal". Everything seemed correct meaning I squeezed the throttle and my wraith moved forward. However the settings inside the castle link software are backward. Meaning as I adjust the Brake or set max reverse power it was effecting forward movement not reverse. For now I have set motor rotation to reverse in castle link software and also set my futaba throttle to "reverse". Wraith still runs forward when I squeeze the trigger and forward settings in Castle Link now affect forward movement.

Is it OK to have set up like this? Do you think I did something wrong to have initial setup to end up with backward settings to begin with.

When using Castle and Futaba, you must reverse

It's probably going to come down to wheelspeed.. I couldn't imagine the 2200 on 2s personally. At 3s it seems perfect...

What motor are you running now? Likes or dislikes about your current setup?

Well I'm running a brushed 35T Tekin right now but want to switch to brushless. Since I'm running 2S, I was thinking at least the 2700Kv PP. I only mentioned the 2200Kv version because I wanted an apples to apples comparison of the smoothness between the Stubby and Standard versions. So for me, I guess it comes down to the 2700 standard, 3300 stubby, or 3500 standard, all on 2S.

I'm hoping someone from HH will chime in.

The only reasons for running the stubby I've seen are;

-You want to use the mamba micro x (I have this setup and am quite fond of it.)

-space or weight is a concern


I don't think you would be upset by any of those choices.. on 2s I personally would say the 3300 is probably good middle ground. You can always gear it down to slow it down if you have too much wheel speed. Gearing a lower kv motor up to match will add some heat to the party.

I usually run 3s and have a 2200 stubby in a scx10 and it's more than enough for me. (Again I wanted to try the mamba micro) a 3300 on 2s would be very close in overall speed.

I have a 3500 in a bomber on 3s and that's fun too, but way different animal.

As far as startup as far as all my research has shown gearing down will help more than the kv. So another reason to go up in KV and gear down.

I'm sure JRH will chime in though and I could be totally wrong here, just sharing personal experience.

Each rig and user will be different, so your mileage may vary anyway.
