| Hi Ross and many thanks for your support ! I also thought about using specific Technic "swashplate", but I concluded as you did : collective control could'nt be achieved because of friction. So keeping the large technic turntable was the best way... (...) (20 years ago, 3-Feb-05, to lugnet.technic, FTX)

| (...) Hi Pierrick, that's nice work! And I'm glad I could provide a little inspiration. The weird thing is, that helicopter was the first MOC I built after my dark age too! I like how you control the swash plate (turntable) from below - the probably (...) (20 years ago, 2-Feb-05, to lugnet.technic, FTX)
| | | | | Re: using PWM output to control Lego motors
|
| (...) The signals output by the RC receiver will drive servos or RC motor speed controllers. The signal consists of a pulse of 1-2ms width in an 18ms cycle. For a servo, 1ms corresponds to 45 degrees turn one way, 1.5ms to centre and 2ms to 45 (...) (20 years ago, 2-Feb-05, to lugnet.robotics, lugnet.technic)

| Just a few words from a newbie annoucing his first MOC : a (yellow) Technic Helicopter. As I said on (URL) MOCpages>, I had left my Legos from ten years now, and thanks to my kids, who are now asking me to play LEGO back, I have retrieved old Lego (...)

|
| (...) Thank you, this clarifies things for me quite a lot. I was thinking that PWM was PWM, but now I see the important difference -- one is a means of transmitting data, and the other is a means for controlling current (integrated over many (...)

| | | | | Re: using PWM output to control Lego motors
|
| PWM for servo pulse is on a three wire system (Pos, Neg, and data). The pulse is a series of different length square waves sent to the servo or ESC in a certain length of time. This pulse is then translated by the servo or ESC as a "position" it (...) (20 years ago, 2-Feb-05, to lugnet.robotics, lugnet.technic)

| | | | | using PWM output to control Lego motors
|
| In my ongoing quest to control Lego robots by radio, I've uncovered some receivers made by GWS that work with a standard model airplane transmitter, and have 4 channels of standard PWM (pulse-width modulation) output. For example, see (URL). But now (...) (20 years ago, 2-Feb-05, to lugnet.robotics, lugnet.technic)
