Hey guys,

I was just wondering where I can get a Lego rc buggy motor in the US for a cheap price

I know you can get them off bricklink but I really don't want to spend 40 dollars for one motor

If not, then is there any other motor that can be used instead as I want to make a small rc car

The xl motor is your best bet for a super fast rc car. The new L motor might be a good compromise as it has about 300-400 rpms (I dont know exactly) and a decent amount of torque.

I have two, every once in a while theres some on U.S bricklink sellers under $40, but if you don't want to wait or spend $40 you could use a geared up xl motor like mentioned above, but personally I'd get the buggy motor plus cable to connect it to v2 receiver. My first was $26, and later I got one for $40.

You could use an XL motor, but it's mechanicle power output is not much above half that of the buggy motor, and then you also need to gear up the XL motor which will cost you some more power. If you want any speed at all, the buggy motor is the way to go. You can get some speed from the PF motors but compared to the buggy motor they are left in the dust!

I got mine via ebay listings which just had "lego motor" or similar in the description, or the RC cars. You just need a bit of patience, the good deals are fairly rare. I think I ended up with an average price of under 10 euros for my 6 (3 x only motor, 1 x dune buggy (tractor B model) + motor for ~20, and a RC car for ~30), all of these except the RC car were auctions.

+1 for being patient with eBay... I've got 2 RC Racers (so 4 buggy motors), and I paid around AUD$40 each set

make some saved searches.. for either the RC Racer set numbers.. or some other keywords.. then just try and run the searches every week or so

Can you get them from Shop @ Home?

Not anymore!

I actually missed in local adverts buggy set with box and all bits for 70eu. I was too late and an idiot to miss out on that!

I hope OP wont mind if i ask this here too: any dangerous things to look after when you buying second hand motors on bricklinks? Do these motors wear out fast? Big chance of buying half dead motor second hand?

This has probably been answered, but...

Can you run these motors with the current power functions?

Works fine with the adaptor cable.

Yes, but you will also need one of the "Electric, Wire with Brick 2 x 2 x 2/3 Pair" items listed at the bottom of this Bricklink catalog page (you pick the length you want). The 8886 "Power Functions Extension Wire" (first picture below) can be mated onto the old-style 5306b "Electric, Wire with Brick 2 x 2 x 2/3 Pair" (second picture below). One end of the old-style 2x2 electric plate fits onto the RC Motor's red electrified plate, and the other end clips onto the UNDERSIDE of the new PF-style electric plate on the PF Extension Wire, which (in turn) connects to the Power Functions v2 IR Receiver's wire.

"Fine" might be an overstatement, without qualifications. The V1 receivers don't work very well at all; if you put any significant load on it, it cuts out. You really need a V2 receiver.

You may also need to "shunt" the battery pack, to prevent the battery pack's overload protection from cutting the power under load.

The adapter cable you need is this one:

Details here. In the UK at least, the cheapest place to get the cable is probably lego S@H at £2.99.

Just to be clear though, the old-style cable in this is optional, and is just an extension cable. You can connect the adapter cable directly to the motor.

@DLuders: Thanks! I figured you'd be the one to answer me.

EDIT: Thank you also Hopey. Again to you too DLuders, for doing the research to verify. I already have the 8886 wire, so all I need now are the motor(s).

@ Hopey: I just went to my basement to try out the parts. You're correct -- one does not need this cable:

I should have mentioned, I assumed we were talking about the V2 receiver due to current limitations, but those already apply to the XL motors as well don\t they?

@ S.I: On Philo's Power Functions Motors Power Curves webpage, there is this graph showing how the PF v2 Receiver is an improvement over the v1 Receiver. The v1 PF Receiver could already handle two PF XL motors:

I have about 30 of them in my parts stash... and have obtained them through all sorts of means (ebay finds) and have never had a dead or even dying one. If I were to put "dead motor odds" it would be like this

Micromotor = 1 in 2.5-3

9V with reduction = 1 in 15

Buggy = 1 in ~ (none dead that I have ever encountered)

The 5292 motor was made in 2002 so there is a possibility that it has become outdated and replaced by better motors that have been made.

No

Better motors?

The 5292 motor was made in 2002 so there is a possibility that it has become outdated and replaced by better motors that have been made.

The 5292 motor was created as a "special purpose" motor for a line of fast RC LEGO cars. There is a possibility that it will never see a proper replacement, as LEGO has apparently moved to making each motor as universal as possible.

If you can find a "Supersonic" on eBay that might be a way of sourcing the motor(s) - set number was 8366

One on eBay at the mo (in the US) - http://www.ebay.co.uk/itm/Lego-8366-Supersonic-RC-Remote-Radio-Control-Car-NXT-TECHNIC-MINDSTORM-MOTORS-/350694894204?pt=Building_Toys_US&hash=item51a70b6a7c

Micromotor = 1 in 2.5-3

9V with reduction = 1 in 15

Buggy = 1 in ~ (none dead that I have ever encountered)

ohh.. I'll consider myself lucky then! I have a stash of 5 micromotors, and they are all working fine! (one is bit noisier)

I've had 1 9V seize up.. out of about 8

and no dead buggy motors, out of 4

The 5292 motor was made in 2002 so there is a possibility that it has become outdated and replaced by better motors that have been made.

I will describe this statement in more detail since it is misleading. What I meant is that a better metal motors possibly have been made since the introduction of the 5292 buggy motor in 2002. Not that faster Lego motors have been made since the buggy motor.
