New Thunder Power R/C Z3R-8 1/8th Scale (Buggy) sized motors!!

[Darin Jordan]

Thunder Power R/C has done it again!

To add to their already amazing Z3R-540 lineup, Thunder Power R/C has just introduced a larger, 1/8th scale Buggy sized motors (Think "Castle/Neu 1515" sized) in several KV's to their line-up!! And, they are SENSORED as well!!

http://www.horizonhobby.com/Products/Default.aspx?ProdID=THPM18A2400

Sizes will include 1400, 1900, 2100, and 2400KV models! These are 4-pole, 12-slot, Delta-Wind motors, with adjustable end bell timing and sensored ESC connections.

To utilize the sensored mode, you will obviously be limited to the buggy style ESCs, however, the adjustable end bell timing should be able to be utilized by any ESC.

Could make for some interesting combinations!

I have two that I will be testing shortly; one in an Impulse 31, and the other will likely be in a Stiletto. Being that these are intended to be in direct competition with the Castle motor line-up, and that Thunder Power doesn't skimp on their materials, I suspect these will be some serious contenders!!

I'll report back more as testing proceeds!

Darin, looks promising. Could you show/explain what's available in the way of SC's for FE applications ?

Currently, Tony, I would think that the BIG Castle Buggy stuff might work, though I would love to hear from Castle concerning how much amp draw these will REALLY handle in comparison.

Working with sensored stuff is going to take a little doing and a special ESC. Not sure yet if Thunder Power is working on anything to match up, but one would have to think they'd have something that mates up to their own motors??

Castle creations mamba pro will run 6s and sensored and sensorless brushless motors.http://www.castlecreations.com/produ...o-onecell.html

No... that link is for the 1/10th scale sized controller, and the single-cell version at that. No way would it hold up to this kind of motor.

This one MIGHT, if you don't over-prop it: http://www.castlecreations.com/produ...a_monster.html

Not sure if that one is sensored, however.

NOTE: You can run these motors in our standard, UNSENSORED mode, just like we usually do. Adding the sensors just gives you more control over the power curves, etc., which may not be as important for most boat applications.

it will run the cc 1515 2200kv no problem. I have one running (racing) a 1515 2650kv on 4s in a mugen 1/8 truggy. A lower kv motor on 6s would work with proper gearing.
The mamba monster does not have sensored capaibility

Interesting... I'd be VERY surprised if it would hold up for very long in a 32-34" Mono, running direct drive, with the 2100KV motor, for any length of time. We're talking about over 150A continuous... Way above that little ESCs rating.

BUT, I've been wrong many times before... It could work...

[1truckerdan]

I used the mamba max esc ( 1/10 scale esc only rated for 3s) on 4s and 5s with a KB45 1600kv in my LST conversion for 3 years.

[1truckerdan]

the heat sink would have to be taken off and replaced with a water cooled heatsink

[1truckerdan]

here is the pagehttp://www.castlecreations.com/products/mamba_max.html
3s is the recomended max but Many of us used 4s and 5s without the red wire (bec) hooked up. we used a external power source to power the tx added 3-4 caps and a fan

[1truckerdan]

Ok Darin I stand corrected
I just got off the phone with Joe Ford (at CC)and he says that the constant amp draw for a marine application will be way past what the mm pro can handle. In a land application the amp draw drops as the car/truck reaches top speed, unlike the marine application where it stays higher at speed.He also said there in no bennefit to run sensored motors in marine applications, running in sensored mode isn't as efficiant as sensorless

you would have to use a tekin 1/8 speed control to use the sensor with that motor, but the sensor part only works for startup then changes to a non sensor state

Guys... I did some further research and you can run these motors in sensorless mode using any standard ESC, just like you would the Castle, Neu, etc... The timing on the endbell only comes into play when in sensored mode.

I have a sample motor that is 2450KV (a test mule, not a production motor) and the thing is WAY too fast on 4S to keep my Impulse 31 in the water. I ended up detuning it by running 3S and using an X440/3 and it was still VERY fast... Ran the motor for a 1-Mile race distance without any water cooling and the temps were under 150... I haven't test fit it yet, but I think that the Castle style water jackets from OSE will fit. You'll need a shorter one, or might have to make a mod near the solder tabs, because of the way the Thunder Power positions the solder tabs.

Solid motor. I am looking forward to getting one setup with a water jacket so I can really see what it'll do.
