"This is pretty hard to get the hang of, if you are going to use NXT-G then you will need to get a Block for it. This is a sensor that measures on the Y,X, and Z axis. Really handy, If you don't know much about this sensor it is like a Wii Remote where you point it the sensor gets different readings."
"This is a very good Piece of equipment, if you just have a motor and a battery box and looking into making your models RC this would be very helpful, It has about a 25-30 Foot range Indoors, and about a 15-20 Out doors. This has been a fan loved piece so there where three types, Most people don't know about that this one had a older one it looked the same and acted similar, It had a 10-15 Foot range inside and about 10 foot range outdoors, I would recommend buying it from a place like LEGO because they are only selling the 'Newer' one, The V2 Featured in the Rock crawler has better battery to motor power usage, so the motors spin the same speed but the battery uses less power, I have the V2 and I think it has a little better range (though I haven't tested it yet) I can't say what to do right now, Wait and get the newer one (though it isn't much better then this one) Or just have this one Because we don't know if this could come out in a day or a year it is a hard choice.
Value for money is excellent, $12 to make awesome RC models is totally worth it. They do break after about 3 years I have just had my oldest one pass its life time.
Play, Wow all I can say is that these make your model that much better. They are so fun whether it is from Driving your LEGO train around the Christmas tree, to Driving your LEGO Jeep outside this is perfect for every place.
Unlike most of the PF parts I don't know if this is water proof, the motors are and I have tested them but I don't want to test this. Mainly for Technic building, it has two front Pin holes then the rest of it is studded.
The video I attached is of my Jeep I built and it is showing my Technic model using this part. This is outdoors and I am about 10 feet away at the time."
"We don't see many of these and it is very nice to have a classic that we can remember. It is built good, Looks great, and over all a great model!!! I love this and I would strongly recommend getting it!"
"Okay it moves there is one piece that you need to fix on page 64 of the second book you add a dark gray gear DON'T ADD IT if you have more technic sets (you should if you are buying this) Then add a light gray gear that turns with the drive shaft and presto it will move!!!!! Best buy ever GET IT!!!!! SUPER I build high complexity robots (Mindstorms) but i couldn't make cars because i didn't have the pieces this helped SO MUCH it has lots of car parts with good suspension and it can steer with a add of a motor. GET IT PLEASE!!!!!!!!!! BUST BUY EVER!!!!!!!! Picture is one of my Mindstorms robots that I used A LOT of parts from this set!!!"
"Great sensor!!! it has all the things Y,X,Z axis Super!!! It is great like a Will remote it can detect motion! It is my favorite sensor!!! GET THIS NOT THE GYRO this is a lot Easier and I like it a lot more. It is hard any Third party sensor are Extremely Hard for People that have a NXT for under 2 years!"
"This is a great deal it is made for you people who use Lego and power functions it has long life good charge time and stops when your out of battery IT DOESN'T slow down. If your like me then in your house you more then likely have a charger for this product I did. Look at what type of charger it is and see if you have it. THIS IS GREAT a little on the expensive side but that is fine. YOU SHOULD GET THIS!"
