Bought the new excavator, which was great. Took it one step further with the motor set. Turned a great set into awesome. The motor takes away the hassle of manually rotating the gear shaft. It brings the excavator to life. I like the motor set so much, I may have to upgrade to the infrared controller. Just wish the battery box was a little smaller.

Great product poor value as set
Great products, BUT I highly recommend that you check out the cost of the main components separately as it comes out a LOT cheaper.

Great Starters Set
Comments about LEGO Technic Power Functions Motor Set (8293):
I got this set because I wanted to start getting into Lego Power Functions. And this set was the perfect starter set! Firstly the box is actually very big for the size of the set. It is about a 1/3 full. Inside the box I found a booklet, a M-Motor, a battery box, a control switch, a pair of LED's lights and a bag full of parts to help you use with this set. Booklet: The booklet shows all the information you need to know about batteries and other sets that are Power Functions ready. M-Motor: The M-Motor (or medium motor) is about 6 studs in length and about 3 studs wide and high. It is actually quite fast for it's size. Since it's the smallest motor, you would probably expect that it would perform terrible, but surprisingly it doesn't. It has a lot of toque and is quite strong and robust. Definitely a good motor for mechanisms, machines and small cars. Battery Box: The battery box is about 11 studs in length,8 studs high and about 4 studs wide. It takes 6 AA batteries (9 volts). On the top is an orange switch for turning it on or off. It can reverse the current so it can go in forward or in reverse which is pretty cool. Control Switch: The control switch is 4 studs long, and about 3 studs high and 2 studs wide. If you turn on the battery box with the control switch attached and the motor or lights attached to the switch, nothing will happen. You have to then pull the orange lever on top of the switch forward (which would make the motor turn forward) or pull the lever back (which would reverse the current - make the motor turn backwards). If you do this with the lights it will just turn them on, no matter which direction the switch is in. Lights: The lights can fit in Lego Technic beams or in studded beams. In the middle of the cord is a separation which means the the lights are separated. They are LED's so they are quite bright. Pieces: In the small bag of pieces you will receive some gears, axles and 3 universal joints. Overall this is a great set especially if you are new into Power Functions, like me! Thanks reading.
Bottom Line Yes, I would recommend this to a friend

Great Parts but Poor Value as a Set
The parts in this set are great for getting your models moving, and lit. In most cases they can be fitted to the main model of a Technic kit in 15 minutes or less by following the extra instructions. Upgrading with Power Functions adds a lot of play value to a model. The value-for-money from this particular set has been eroded by the rising price. If you add up the cost of the main parts: Battery box, Motor, Light Brick and Switch then it comes to only 71% of the set price. The remaining gears and universal joints are not worth more than a quarter of the difference so the set price should be reduced considerably. Until this price discrepancy is fixed, I would recommend that you check the set you are upgrading with Power Functions and if the small parts are not used, just buy the individual Power Functions parts. Aside from that problem, the parts are really good. The battery box takes 6x AA cells. From one position the cell is hard to get out when you change them but a screwdriver at the positive end of the cell can lever it out easily enough. Having bought 3 of these kits and several Technic kits that each came with a battery box, I now have too many of them, but they have another use that is not so obvious. You can use an empty battery box to convert the 9V output of a mains-powered LEGO transformer power source to the Power Functions protocol. If you have a 9V train controller, or another source that connects to a 9V plug, then you can use a Power Functions cable (set 8886 or 8871) to connect the 9V plug to the (empty) battery box. If you also connect a Power Functions IR Receiver (set 8884) to the battery box then the switch on the battery box will connect the power source to the 9V and 0V lines to power the IR Receiver. It will work only one way round so check polarity before you leave it on for more than a second or two. If the green light on the IR Receiver doesn't light up then you have it the wrong way round; just move the battery box switch the other way. The Medium Motor has been around for a while now. It fits well with most theme sets and for the auxiliary functions of Technic sets (the drive function on anything large should use the L- or XL-Motors). It also works well in multiple. In PF trains it is advisable to use one Medium motor per bogie for a diesel loco, or consider an L-Motor or the Train Motor. The Light brick is brighter than previous LEGO light bricks and it is easy to fit the lights to a 1x1 headlight brick or into the holes in a Technic beam. The clear LED housings include a safety feature to prevent the lead being pulled out. The black brick half way along allows the wires to each LED to be thinner and hence to turn more easily and fit into cramped spaces. I fitted the LEDs to a semaphore bracket signal (2 signals together) with no trouble. The thin wires could be held easily by some parts with suitable slots. My largest project with LEGO LED Light Bricks so far is a lantern. It uses 12 Light Bricks, 1 switch and the AAA battery box (set 88000). When I used the lantern as a pantomime prop it lit up well enough for the audience to see the lights. It is also bright enough to see your way in a dark room. It was a challenge to fit all the wires inside but it helped to stack the plugs and black bricks in 2 groups of 6. The LEDs were inserted into Technic beams with yellow filters on the other side. The Black brick contains a bridge rectifier and capacitors so that the LEDs both light up with the polarity either way round and light up at the minimum speed setting of an IR Receiver (set 8884). This is good for headlights and general lighting but I would also like to see a future Power Functions product where the LEDs light up alternately with the change in polarity. This would be useful for a police car (2 blue filters), railway signals (1 red and 1 green) or trains that change direction (1 white and 1 red at each end of the loco). Perhaps this piece would have a different colour of 2x2 brick in the middle to tell users that it has a different function. I have experiments with a red/green multi-colour LED to make "searchlight" railway signals compatible with Power Functions, which will have red, yellow and green available from the same aspect, corresponding to the 3 states of the pole reverser switch. Whilst I might hope for that as another future product, it is less likely to happen. The pole reverser switch just changes the polarity. It does not isolate the power as the battery box switch does. Use the battery box for on/off and the switch for direction change. The pole reverser switch is versatile. It can be actuated from a lever or via a rotating axle from either side. A tiny switch on the back allows a set of switches to be made into a control panel and have their individual polarities set so that "down" always means "on" or whichever function you have assigned to it. An example is a railway signal box, where "down" means the points are set to the minor track, whichever way round the points are. I have put together a set of these switches to drive a set of PF Servo Motors (set 88004) to actuate the points on my railway layout. The universal joints work well and are an improvement over many years; they were in the first Technic sets in the 1970s. They used to be 4M long and are now 3M long so they fit into smaller spaces and fit better with the studless Technic system. The white clutch gear helps to prevent the motor straining if the function it drives has end-stop limits. It works well with limited-travel Technic set functions. The only application where I found its torque limit too low was in changing railway points quickly; it takes a lot of torque to overcome the resistance in the slider. It worked OK with various gearmotors up to the Medium motor but in location where I couldn't see directly it was better to use the Servo Motor instead because that has a built-in limited travel. The design of the 8-tooth cog has been changed now (the new one has better torque capability) so there might be a change to this set soon. The 24-tooth cog is a stalwart of the Technic system and useful for gearing down the motor (with the 8-tooth cog). In rarer applications it may be used to speed up the motor for a small propeller. I do miss the extra axle holes that were rotated 45 degrees compared to the centre axle hole. Those holes were used in the early Technic piston engines but their particular distance from the centre axle hole (0.707M) gave them another application because the stroke length of a small (1/5) pneumatic cylinder is less than 2M and the earlier version of these cogs with the 45-degree cross hole allows the cylinders to be made into a pneumatic motor or steam engine. Look on the Bricklink site if you need the old style cog for an application such as this. Overall there is huge amount of value in this set, once the price is sorted out.

A little tough to put ...
A little tough to put together but my son likes it.

Very useful for beginners
A very useful set for beginners. Goes very well with other Lego Power Functions pieces such as the IR Receiver + Speed Remote Control, XL-Motor. I hope to someday use it with the Servo Motor.

The power function is added to some Technic Lego to add movements to the set. It is a great addition for more enjoyment play time. It added the sense of movement to cars, tractors and others. It teaches kids about gears and pulley.
