Default Tamiya Brushless Motor System (45039) Question

Has anyone had experience on the Tamiya Brushless Motor System (45039)?

http://www.rcmart.com/catalog/rc-bru...r-p-28425.html

I plan on using it for drifting.

It is a good unit for drifting or even for touring (although there is no category yet available for this 12T BL Motor).

I have had this unit and used it for drifting and it was great to use. The Downside would be, it is not lipo ready. You'll be needing LiPo CutOff for it.

I plan on using a 5000mah Intellect Battery for it. Something simple. I just hope it's got allot of torque.

It has torque alright but the problem with sensor less BL Motor is the "CHOKING" thing at the start of the run from a full stop. But above all, for drifting, it is a good UNIT.

But if you want, you could get the EZBrushless Unit, it is the same but cheaper.

It says it has a low voltage protection system.

Can I use any Sensorless Brushless Motor with the Tamiya Brushless System 45039 ESC.

What's the smallest(most compact, small form) Brushless ESC with/without built in lipo cutoff they make?

If you guys don't mind I'd like to stay on topic. Although I see where your going with the face palm.

http://www.rcmart.com/catalog/rc-bru...1-p-28424.html

It says it has a low voltage protection system. Is it a cutoff for Lipo? Can it use lipo?

Can I use any Sensorless Brushless Motor with the Tamiya Brushless System 45039 ESC.

Hey DriftWood,

Low voltage protection for NiCd/NiMh batts but not LiPo Batts. You will be needing separate LiPo CutOff or a Warning device to be able to use LiPos on it.

Well, regarding to your other question if you could use another brand of motor with the ESC Bl Unit, unfortunately, I haven't tried it. Although, it says in the manual, Any Tamiya BL Series Motor can be used, maybe sensorless too but the tamiya didn't specify any, especially the limitation of turns of the BL Motor.

So far, I think the esc that has a built in lipo cutoff of Tamiya is the Volac ESC that looks like exactly the LRP Competition TC Spec. For the others, none

Quoted for truth.

Back on topic. Why hasn't Tamiya gone bigger with their brushless stuff? I don't see them for sale or advertised very many places. It looks very similar to a Castle ESC.

Well, maybe because they are not focusing on such product as for the Brushless System. They are more focusing on their expertise like the Kits, and so on.

They leave those things to the other brands who really specializes on them like the LRP, SP, etc.

Just my thoughts

But Tamiya has such a rabid following that if they wanted to they could have a very big market presence. Kinda seems like a missed oppertunity for them. HPI just rebadged a Castle system with the Flux, so Tamiya could do the same with a different system. Oh well I guess thats why I don't work in marketing or sales.

Maybe they saw that coming already. They are just trying to research more on some stuff, whatsoever.

But if I were in their case, I would not bother to grab that opportunity because I have a lot of competitors and they are somewhat already at the Maturity stage rather than introduction stage in a marketing perspective.

I would somewhat stick to what I have which is retaining from the maturity stage and maybe later on think of something new that less has just thought of or better yet, none of them have thought of. But remembering the risk.

Anyway, as far as I am concern, it is their department, not mine

Just a thought and no harm done
