I'm planning on to getting a myself an Amp truck to match my son's (which he'll like) but want to upgrade mine a bit for a bit more speed, which I'll be able to dial out with dual rate settings so we can race them together when we go out and be fairly even.

I know I'll either need to get a new receiver to go with the stock radio, or get new radio gear which is fine (probably will go this route) and I don't mind getting a new ESC as I can keep my stock one as a spare for my son.

However I'm not quite sure what to go for, I don't want to spend too much as I've already bough my sons his Amp and been repairing my old Tamiya buggy so fund are rather limited.

Do I get myself a Hobbywing 1060 esc (about £19) and am HPI 15t motor (about £7) or are there any entry level brushless combos that I could go for that don't cost vastly more?

(eg is this any good?: https://www.amazon.co.uk/GoolRC-Upg...id=1487520095&sr=1-8&keywords=brushless+combo)

I'll be sticking with my exisiting Nimh batteries for now as it makes it nice and simple for using for both mine and my son's cars and I already have those batteries! Maybe in the future I'll move to lipos but not for now.

Ta muchly for any help.
 
You can run that 15t brushed motor with your stock electronics. I haven't personally owned the GoolRC combo, but I've heard pretty good things about it. I ran the Titan 12t in mine with stock electronics. I found out later the electronics are only for 15t and higher, but I ran it like that for 6 months and never had a problem. The Titan was definitely a lot faster than stock.
 
I did consider running the 15t with stock electronics but I think I'd rather upgrade to give me better future options and also it'd give me spare electronics for my son's truck if needed.

The titan 12t is about £25, if i could pick up a brushless combo for not a great deal more I'd imagine it'd be quicker than the 12t right?
 
You can increase speed by changing the pinion gear (this may lower torque a bit but increase TopSpeed). if you're going to go through all that trouble though, I would look at getting a better car. Maybe a torment or a ruckus. They have better electronics and an overall better car. Another option would be a boost if you want to stay in the ECX family. The boost has better electronics and isn't that much more then the amp (in the US). The boost also has the ability to turn down the throttle and the steering capability at the remote control.
 
Part of the reason I want to go for the Amp is because I really like it and also my son would love us to have matching vehicles and I would quite like it too.

I'm not going to go racing with this vehicle or anything, ell not beyond racing round the back garden and local parks so I'm happy with it being an entry level vehicle, I just want it to be quicker for times when I'm driving by myself or with my brother and not my little man.

Can't seem to get the Boost anywhere and the others seem to be considerably more money..and ugly lol! ;)
 
Ruckus with a orange kn torment body looks great imo. But a body is a body, electronics are electronics. You are considering upgrading electronics, you should also consider the cost related to it in comparison to one that already has the electronics. Perhaps upgrading both to better cars would yield better cost savings. The torment and ruckus both aren't blazing to start off with and are relatively easy to control, but the electronics are there to easily upgrade (you can even buy different bodies to put on).

But either way, do what you wish the amp is great.
 
If he likes the Amp I wouldn't push another car on him. Why go through the trouble of selling the car and buying another if he likes the car. I would suggest that brushless combo and a Flysky fsgt2b radio system.
 
Yeah I'm pretty keen to stay withthe Amp, so reallylooking for advice on what would work well with that. Also spotted a Turnigy Trackstar 9T Brushless Motor & 60A Speed Control ESC combo for about £45, anyone any experience of these?

@Rock3400 does that radio system have a dual rate control?
 
That's one of the brands I was contemplating but not found a great deal about them.

I would go this route, but see my note below on that radio.

Both the trackstar 9T and that particular goolrc that you posted are 380 size motors in a larger can. That's not a problem per se, but you're not getting the full torque of a 540 sized can. You can recognize the 380 sized motors by the grooves that run around the can. You can get both goolrc and turnigy motors in true 540 size and I recommend you go with those. Here is an example. Get it from a trusted ebay seller and they'll cover you if the product is faulty (always a possibility with Chinese junk electronics), they avoid negative feedback like the plague.

For cheap radios, there are quite a few good options. I would forego the flysky gt2b because it has documented problems with the expo, the later and upgraded model (gt3c) does not have this problem and is a better buy overall. It has end point adjustment, which does the same as dual rate only through a menu instead of a knob. I own this radio and I find it excellent, only the menus are kind of clunky and cumbersome. It comes with a rechargeable lipo, and it's own low voltage alarm.

Another radio option is the Austar AX5. It has a slider low-medium-high for the throttle limit. I haven't personally used this radio but I think it will be my next buy when I get one because it is very cheap and seems to have all the functionality I need.

A third route for radio is to pick up a used stock transmitter and receiver from ebay. Something like an Axial AX3 can be yours for $45 in perfect working condition. The downside of this route is that extra receivers will tend to be expensive.

That's good to know, thanks. Looks like I can pick up one of the combos you poster for about £35 would be a a better choice than an esc and a 15t would it not?

Cheer re the radio gear thoughts too, good to see that they cna be had for not a great deal of money.
 
Well brushless is supposed to give you more power, longer runtimes and longer motor life, but I'm too fresh to be able to testify to that from my own experience.

Whether the goolrc combo is a better buy than the hobbywing + firebolt depends on what you want from it.

The hobbywing route is a proven product by big brands with good QC and meaningful warranty. It will be appreciably faster, but not THAT much faster than stock. The motor will wear out and slow down but it's cheap anyway.

The goolrc route is much more exciting. More speed, better efficiency and the motor shouldn't wear out. But QC and warranty are almost non-existent so you are gambling on not getting the one assembled by the new guy on friday 5 mins before end of shift. And the higher speed and torque will mean you will start breaking things on the Amp rather quickly.

Are you prepared for some adventure?
 
You see that's my issue, while I want a bit more speed I don't need vast amounts more really and I don't want to end up with a truck that keeps breaking parts etc. I think I'm leaning towards the firebolt route though wondered if there are any other brushed motors that would work with the hobbywing and that might be worth considering?

That GoolRc combo you linked, would stock gearing be fine to use with that setup? If not, what gearing would you suggest?
 
It's hard to answer that. I'd expect stock gearing to be fine in the sense that motor and ESC should not get too hot, the car will accelerate faster than stock and have a higher top speed than stock. But:
a) I haven't tried this particular motor on this particular car, I am judging off the experience of other people running different KV goolrc motors on different vehicles (closest ones I know are a 4370KV in an Amp with smaller wheels, and he geared it higher than stock, and a very large 3660 sized 2650KV in a Slash, running stock gearing),
b) a lot depends on where you run: is it wide open space or tight, twisty track, is the surface gravel or tall grass or beach sand, ...

I expect the sweet spot to be higher than stock gearing. But I can answer more accurately when my 3100KV will finally arrive and I can test it for myself (the first one got lost in the mail :( ).
 
Seeing as the Firebolt seems to still be out of stock, I wonder how the Absima Eco Thrust 15t compares, I have the 18t in my Fighter Buggy and it seems pretty good.
 
Put it in and try :) there is nothing particularly special about the Firebolt, except that is is ubiquitous and cheap.
 
Just waiting on pay day then it'll be Amp and 15t time, radio gear etc might wait a bit to save me some money.

Might go for upgraded bearings too, though again might wait on that.

The Absima motor is also nice and cheap, only a couple of quid more expensive than the Firebolt
