I can use RCX to control train and PF motor with PID directly, I also can use RCX to control PF receiver with train and PF motor without PID, so I am Curious if I can then use RCX to control PF receiver with motors with PID. Now you told me that is impossible, I think that I got answer, though it is very Shame! This is what I talked http://www.eurobricks.com/forum/index.php?showtopic=45440

Sorry that I am not high school student:( I don't think you are right about PID control train, train will move slowly on curve if you set the same output power, but using PID control you can increase output power on curve, you should check Thorsten Benter post in this forum, you will found PID control train move in constant speed even in curve. And I don't have PF remote control but I am using RCX and its remote to control my PF trains on the fly, this is why do I have such strange thinking...

I know if PWM lower 30%, train is never moving as lower torque. I am porting RCX PID speed control from RobotC by Thorsten Benter to brickOS, so that I am thinking if I can set any percent PWM for receiver, then I can use PID speed control to PF motor, that is why I asked such question.

I want to know if someone can hack it to set PF receiver PWM to 0 - 100%, because like old RCX, lego firmware only support output to 0 - 7 (= 0 - 100%), but brickOS can set to 0 - 255 (=0 - 100% step in 1/255%), and RobotC can set to 0 - 100 (= 0 - 100% in step4%).

The output of PF receiver can be set 1 - 8, and relevant PWM percent as below stop 1: 26.4% 2: 37.9% 3: 49.4% 4: 63.2% 5: 74.7% 6: 87.4% full throttle I want to know if it is possible to set PWM between 0 - 100% to PF receiver output?

Thanks for your info. This is not perfect as there is a space between cheese slope. Is there any other way to build it?

You are clever:)

By the way, can you tell me how many mm about cheese slope height? Or a pair cheese slope's size?

Can you show me a sample?

As you know, there are two arrow wall on set 10233 as pictures, there are built by thick stop and plate with clip. I want to know if it is possible to build the same arrow in one brick width? I mean not using stop and plate with clip.

Thank you very much, This is very simple! But I am not sure why people like to cut wires and do a complex DIY for the same purpose?

Is this correct in picture? do you mean that?

Can you tell me more detail about lego way to use 9v battery?

No any info about this time down...

Do you think the quality is higher than Enlighten's?

I think the author doesn't have all new clone brand set, recently a new brand named Gudi has quality near Star Diamond, also no reviews:)

Can you tell me which is copied from which?

I think so, by the way, do you know any relevant lego set no? I just want o know it...

Here are what I knew at the moment: SudiniNo Pieces LegoNo 25002 832 25003 764 25004 791 - 7939 25110 928 25111 1008 - 10219 25412 186 25413 150 25414 199 25415 215 25505 226 25606 257 25705 410 25807 588 25808 573 25809 483 25810 517 25811 462 25812 586 25813 531 25902 630 25903 681 25904 666

There is a new brand named Ausini which build a lot of train set, you can find them here http://003.tsdn.net/en/ProductList.aspx?Class1=17 http://003.tsdn.net/en/ProductList.aspx?PageIndex=2&Class1=17&Class2=0&type=&keyWord= I just want to know if they are copied from lego set and which set number, can you help me?

I found all discussion are about width and length, but how about height? I want to know is thee any better height for 6w, 7w and 8w train? I think this is better as below, what do you think? 6w with 18 plates, 7w with 21 plates, 8w with 24 plates space between baseplate and roof slope

Brickset disappeard!

Thanks for your explanation, it is so simple, great! In fact, I created a deCoupler with a 9v motor, my design is in opposite way. Two beams will push car off away locomotive, the concept is very complex though it does work.

Does anyone tell me how this is to decouple? I am not sure about its concept...

OK，I will modify it.
