Tekin FX-R ESC

[lin6499]

I need a brushed ESC and am interested in FX-R ESC because it is compact.

wonder if it is suitable for a 1/10 EP buggy or not.
Anybody has experience with it?

That looks like a nice brushed ESC, works down to a 12T motor, which is pretty powerful for brushed. But at nearly $100, it's way more expensive than I figured.

I'm not sure how much bigger it is, but a Hobbywing 60A brushed ESC has similar specs, for a whopping $21.00:

EDIT: Here's a comparison of physical specs:

FX-R: 28 x 20 x 10mm / 18g
Hobbywing: 36.5 x 32 x 18 / 39g

Looks like you'll pay quite the premium for just over 1/3 smaller size.

I'd go hobbywing, if it was my money.

I have a similar esc (Tekin) in my rock crawler, came as a set with a 30T motor. Works good, reverse is kinda wonky though. Kind of an all-or-nothing deal. In my experience Hobbywings have been good to me. I have at least 4 of them.

Yep, I do need a compact ESC even though I will have to pay much more for just over 1/3 smaller size.

The thing is the FX-R ESCs are mostly mounted to rock crawlers, which I don't have.

All I have are 1/10 buggys.

can I ask why you need 'brushed' vs. brushless?

Most of my RC cars are vintage, dont think they can handle a powerful brushless.

a smaller brushed ESC will work fine and fit in.

Easy response to that is don't use a "powerful" brushless setup.

Most any of these vintage ride can handle a mild 17.5 and I know surely they can all handle a 21.5 or 25.5 setup.

I have Hobbywing Justocks and eco power 17.5's in most of my cars. Blinky is the key cause I do feel the boosted ESC's could cook a vintage gearbox

Given the Tekin is made for rock crawlers, I'd doubt it could handle a faster buggy motor. They're designed for 30-35T motors, you're likely running half that, meaning much more power. The Tekin doesn't even have a heat sink. You'll likely pay the extra money, and blow the esc.

I know what you mean, but I need a small esc for my custom-made RC car.

There's no room for a regular size brushed/or brushless esc.

The FX-R is a great buggy ESC. It was never designed for crawlers, it's just useful for them due to its small size. It is a lower budget version of the FX-R Pro which has an unlimited rating, the FX-R uses the same control board, but less FETs. The FX-R will handle brushed motors down to 12 turns,
It has only become a crawler ESC as that is currently the only market for high end brushed ESCs today.

I run the FX-R, both in crawlers and buggies, and they work fine in both types of cars. If you need a small brushed ESC there's nothing else that is so small. Although if you can fit the Hobbywing 1060 into the buggy that would be my recommendation.

great. I do appreciate your help.

I think it would help us all give you the right advice if we knew exactly what it was going into. You mentioned "custom 1/10 car", but that leaves a LOT of room to play with. You may not want to spill the beans, but it would help determine what's right for your setup.

[Coelacanth]

Good point, yellowdatsun. Back in the day, our vintage cars had MASSIVE ESCs and servos and receivers...I find nowadays that adding modern ESCs and receivers leave TONS of room. I honestly never felt like I needed something even smaller.

It's about Kyosho Optima with mid motor conversion.

I'll upload some pictures later on.
