Toro 1/8 Combo

[fastbaja5b]

Just picked up one of these speedies to test so will do a review, initial thought is it's fairly big tho. To keep it fair, and at the same price point as the MMP (for my comparison) I bought two, so one is NIP as a spare.

On a side note, it has no trouble powering my LED's that the MMP simply refused to, and it too has a Switching BEC.


...China ESC 1, Castle 0.

It would only make it only somewhat "slightly" (Very slightly) harder for the cloners to get their hands on them. People sell used/new stuff on ebay, and you can't make all of them refuse to ship to China as well. It would be pointless for a business to refuse to ship to China. It would just lose money I imagine.

Pretty stupid comment... you are comparing the BEC (stolen from the Mamba Monster design) to the BEC on the Mamba Pro. They are different circuits, with different capability. I'm sure if you tried your LEDs on a Mamba Monster, they would work EXACTLY the same as the BEC on this cloned and stolen design.

BTW -- this "clone" has a copy of the V2 MMM BEC circuit. So beware.

Also, they are using NTMFS4833 MOSFETs, which are cheap, but are much less capable than the NTMFS4901 MOSFETs used by Castle.

And yes, I am in a pissy mood.

Pat, go get yourself a nice coffee and donut/bagel. Better yet, send an employee out to get them since it's probably snowing as much if not more than it is here a couple hours north of you.

What is it about the 4833 that makes them less capable? IIRC, a while back you mentioned something about switching losses but not sure.

Well, a couple of things.

The 4833 has a poor gate-drain/gate-source charge ratio. This means they can't be switched very hard without shoot-through. This also means they ring more, which causes more switching losses.

They also have about 30% higher RDSon, which means higher i^2R losses. (1.5 millohms for the 4901, 2.0 milliohm for the 4833)

So, in short, they run much hotter at the same current than the 4901. But they are quite a bit cheaper, and more available.

I love it, and you wonder why it costs less. Stolen r and d and crummy componets sounds like china stuff to me. Who needs headlights on their RC at the track anywho? Buy it right and buy it once it's cc for me!

I think I remember some of that when we were talking about the 4933 the MMPro was using.

I believe Tekin still uses the 4833 in their RX8 ESC. I have only one of those ESCs in a smallish vehicle (Losi Ten-T) so it's not working hard enough to judge it properly, but I've been running without the fan forever and it never gets warm. This makes me want to try it in my XT8 truggy to see if it heats up any more than the MMM I'm using, just for giggles.

Yes - -the 4901 is a 4933 that has been customized for Castle. The 4933 is the "next generation" FET from Onsemi that fixed a lot of the issues with the 4833. -- and it's lower RDSon

The way I see these clones they need to be cheaper so I can just throw them away when they crap out. That is what they are, throw aways. No customer support and certainly no CC style warranty.

I will stick to CC cause their stuff works, they have great customer service, and Pdel is one of us!!!!

Well Said!

[bigbadtaz]

i know castle loves getting their balls stroked here...........lol i am a fan of what works and does not break the bank and yes i do have castle motor and escs

[golfito]

I am very happy with my MMM. They are very reliable and recommendable.
Buy a Chinese combo failure. Is on the way to the warranty. I hope to have answers from the manufacturer.
Here where I live, there are no representatives of Castle. It is difficult to access the products in Argentina.
My combo MMM I imported it, but I pay $ 440 (crazy).
The Chinese combo comes to my house for $ 150. (early failure).
I always like to buy Castle. I hope that someone representing the brand in my country. It is becoming quite popular electric cars here.
Greetings.

Least he has some; from all your posts, you seem like a Castle hating troll who cant back up any of your silly claims and statements so just goes quiet instead when people rubbish what you have said.
