Zerobricks Posted June 24, 2012 Posted June 24, 2012 BTW how are the L motors? Any difference compared to M? Quote
efferman Posted June 24, 2012 Posted June 24, 2012 maybe, or maybe they want sell something like this, only with speed remote, next year Quote

Alasdair Ryan Posted June 24, 2012 Posted June 24, 2012 (edited) Does any one have a rough price to the servo motors? Edited June 24, 2012 by Alasdair Ryan Quote
allanp Posted June 24, 2012 Posted June 24, 2012 (edited) Does any one have a rough prize to the servo motors? 7L x 3W x 5H EDIT: by prize I guess you mean size, right? Edited June 24, 2012 by allanp Quote
allanp Posted June 24, 2012 Posted June 24, 2012 (edited) I meant to say price. Whoops, i'de say about £10, give or take £10 Edited June 24, 2012 by allanp Quote
rm8 Posted June 24, 2012 Posted June 24, 2012 7L x 3W x 5H EDIT: by prize I guess you mean size, right? Too big for fast little cars with 43 wheels Quote
DLuders Posted June 24, 2012 Posted June 24, 2012 (edited) If you have not read the story already on TechnicBRICKS, sunnykoomos just posted this short "teaser" with a mysterious picture of the 9398's servo motor -- "This video will be deleted while the 9398 comes out. Sorry that I can't say where I got this photo." Fernando Correia (Conchas) points out that the Power Functions Servo Motor's "backside" (seen above) shows the "dual output". Would not the new 4L Technic Axle be designed to NOT PASS COMPLETELY THROUGH the Servo Motor's axle hole? On his Flickr photostream, Mahjqa posted this image which has these comments written on the photo there: "So the point of the axle is that it won't slide out in this situation." Question: "Would a normal axle ever do that?" Mahjqa's answer: "Eventually, yes. Especially if there's a lot of force on the axle. Of course, I found that out in the middle of a race, where an axle dropped out of the motor as I was winning :p " Comment: "These gears tend to have a lot of friction - was it a double bevel or an 8-tooth that slid out?" Reply: "It seems to me that the newer gears (the bevel gears, the new mold of the 16z gear) don't grip as tightly. The 8z gear can be a bit iffy at times as well."

Zerobricks Posted June 24, 2012 Posted June 24, 2012 Hehe, like I said few posts back... Too bad they cant be used to hold the gears inside the portal hub. Quote
timslegos Posted June 24, 2012 Posted June 24, 2012 If the set is out than wont the motors be available through Lego Direct? tim Quote
DLuders Posted June 24, 2012 Posted June 24, 2012 If the 9398 4x4 Crawler set could have true "proportional steering" when using the optional 8879 "Power Functions IR Speed Remote Control" unit, how useful would that be for Lego Technic "Trial Trucks" (like the 9398's B-Model shown below)? Recommend getting the 8879 unit (available for $12.99 on Shop.Lego.com ) to take full advantage of the new PF Servo Motor. Quote
davidmull Posted June 24, 2012 Posted June 24, 2012 Someone must have this set by now, we need a video to see its full potential :) Quote
Crtlego Posted June 24, 2012 Posted June 24, 2012 good question, i will ask him edit: yes, by pressing the stop button the servo goes back in center position. conclusion: the crawler has the wrong remote included Wonderful. That is exactly what we needed. Stolen from german forum All I can say is that I can't wait to get my hands on one of those.. or two.. or threeeee If the set is out than wont the motors be available through Lego Direct? tim Technically speaking, yes. We still need the ID numbers though.. unless somebody has posted them somewhere that I have not seen yet.

Recommend getting the 8879 unit (available for $12.99 on Shop.Lego.com ) to take full advantage of the new PF Servo Motor. I feel like it would have its uses although I imagine it is going to be heavy and a bit awkward to place.. I could see it being used in a larger truck with 6 or 8 wheels where the space is not so limiting and the weight is not as big a deal. Quote
DLuders Posted June 24, 2012 Posted June 24, 2012 A fellow on that Doktor Bricks Community topic pointed out this additional source for the 9398 set. Quote
Alasdair Ryan Posted June 24, 2012 Posted June 24, 2012 The B model to the crawler looks way too boxy,I bet if you drove over some thing it would topple over. Quote
freakwave Posted June 24, 2012 Posted June 24, 2012 great news: the servo is proportional with the speed remote. we have only no return to center edit: yes, by pressing the stop button the servo goes back in center position. Thanks for proofing me wrong! never been happier to have guessed wrongly! Quote
Phoxtane Posted June 25, 2012 Posted June 25, 2012 (edited) Between this and the Unimog, I may just be all set to start "building with the big kids" as it were! The most valuable parts in this set are gonna be those new servo motors, believe me; we may just start seeing a small drop in the prices for those hockey springs that many people are currently using for return-to-center steering. They'll still hold dominance for very compact mechanisms IMO... Good thing I've got my first summer job as well, so I may be able to actually get both of those sets relatively close to each other instead of waiting six months for once. EDIT: Evidently I'm one of three people on the planet who likes the black-orange-white color scheme. Throwing some blue in there wouldn't hurt either, if it replaced the black.

kieran Posted June 25, 2012 Posted June 25, 2012 I know this will look good on my shelf, and I am pretty sure the kids will enjoy playing with it was well. Not too long till it hits the shops in the UK the I think I will have to get one of theses. I love the idea of proportional steering on the servo motor, just not that keen on having to use a train remote for it. Quote
davidmull Posted June 25, 2012 Posted June 25, 2012 Why do we need a train remote.? If Lego intended that remote would they have not supplied it? Quote
timslegos Posted June 25, 2012 Posted June 25, 2012 If Lego intended that remote would they have not supplied it? Maybe the different remote drove the cost up too much. tim Quote
kieran Posted June 25, 2012 Posted June 25, 2012 Why do we need a train remote.? If Lego intended that remote would they have not supplied it? My understanding of the small remote is it has three positions per channel, off (centre) and on each side. this offers no ability to control position through the range of off to full on. Quote
DLuders Posted June 25, 2012 Posted June 25, 2012 (edited) In this TechnicBRICKS topic ("PF Servo Glimpse"), Fernando Correia (Conchas) wrote in the Comments, "It works as per the known LPF [Lego Power Functions] Protocol which is public domain. With a PF IR Remote it goes full left/right when the sticks are pressed forward/back (depends on polarity switch). When there is no signal arriving it returns to the center like a regular servo. It behaves similarly when attached to a regular Battery Box. "Now if connected to the PF Speed Remote or the PF Rechargeable Battery it receives modulated proportional signals while attached to the IR Receiver or the Battery. Then it turns proportionally according to the received signal. That's why it does not return to the center automatically. The stop button must make it return to center though." AVCampos commented: "It makes sense: the way the rechargeable battery box and the train remote controller work is by applying a square wave to the PF data pins, with a duty cycle varying between 0% and +-100% (depending on the direction you turned the knob). While a regular motor uses the duty cycle to vary its speed, the servo uses it to vary its axle's position. The "Stop" button knocks the duty cycle back to zero, so the servo interprets it to "go to position zero", which is centre. "If I'm not mistaken, that's also how RC servos work."

efferman Posted June 25, 2012 Posted June 25, 2012 (edited) we have on doktor brick a second owner of 9398, which will post soon detailed informations in his thread. but maybe first after building his 9396 helicopter edit: there are pictures from the servo, the l-motor and the partslist in the doktor brick topic available teaser sorry for the big pictures, the owner wants only direct links Edited June 25, 2012 by efferman Quote
