Does that 8 tooth fit there, isn't there a clearance issue? P.

That is really Nice! can it lift much? p.

It can be difficult to find all the parts in one store (unless its a very expensive store) but I've never worried about where stuff is coming from (in US keep orders below £50 to avoid import duty & tax issues) If you create a wishlist of items then BrickLink will find stores with those items in stock. I have used many stores, but My emergency goto store is my local seller who is just across town http://www.bricklink.com/store.asp?p=masterbuilder1 There are also buying opportunities from AFOL clubs like www.brickish.com P.

yep I remember spending hours with that catalogue.. and most likely still have my copy too.. I think 8020 was my first Technic then 8040.. Sometimes I wish they would do universal sets again... Definitely the best way to encourage independent building, lots of ideas and functions and good for parts, and models you don't want to keep made up... P.

Yup I'd vote for a servo too! (did someone say cuusoo) Perhaps 90 Degrees Left or right (180 total) This 'could' be controlled using the the existing PF system with 7 steps each side allowing position control from the dial remote or full 90 degrees from the on/off levers remote. I doubt this would happen because the 'signal' wires carry pwm power, but it would be possible. Hopefully one day Bluetooth (or alt.) will be cheap enough to make this a reality! P.

Do you mean this Gear? (not a clutch) http://www.bricklink.com/catalogItem.asp?P=94925 Its been around since last year (8053&8043) though so you can't tell anything from it. Mike.

Seems Lego UK are doing their own Technic Challenge: http://www.legotechnicchallenge.co.uk/ More on Technic Bricks http://technicbricks.blogspot.com/2011/08/lego-uk-runs-lego-extreme-machine.html BUT The Gallery is full of Cheats again.. When will they learn? Feel free to post any links to stuff you spot and we'll see if we can get them reported... http://www.legotechnicchallenge.co.uk/gallery/ This Robot Arm by piotrek839: And MAHJ's Stilzkin Bridge Launcher again..

Its just a plastic tank. with two inlet/outlet ports. If you have a T piece and a blob of sticky tack (or chewing gum) and a fizzy drinks bottle (MUST be a fizzy drink pressurised bottle not a water bottle) you can make a far better air tank! The tank is not actually that great it holds about 6 cylinder strokes worth of air. A pop bottle holds ten times that. P.

It is not the nicest piece! If it were my choice I would have designed it with mounting holes above and below the pneumatic tube, and the hoses are tight! Parax.

There is no Clutch in the compressor design (and no obvious pressure relief valve in the pump I was not able to examine it too closely), This could be a flaw Lego may look at.. they have always clutched compressors previously. The hose might be slightly different to previous hose, I was not able to compare it side by side, it felt a lot stiffer to attach, so it does not 'blow-off' under high pressure, I guess that Lego may want to add a clutch but I really hope they do not put back the launch date and just issue a service pack. Clutches are used in the winch and Grabber arm but they are in the devices not in the truck. The issue with the axle alignment is trivial its a one part fix and it does not affect the model as it is, as the deviation is on the steering axle, so steers out. P.

Just a Word of advice guys: Don't put your submission Pictures on the internet! The whole reason for having the Printout is to stop people taking pics from the internets. If your picture is here you are giving it away!!! (its easy to edit an overlay name) if they submit it, then what are Lego to do? accept the first submission? More probably throw both out! but what if they keep it till next year or the year after? what if you decide to submit something else instead, They can use your pictures!! Just don't post the Entry Pics anywhere on the web! by all means show your entries Just not with the verification image!!! P.

Did you solve the problem, of rotation transferring to the other actuators, mechanically, or by programming it out at the nxt? Parax.

But it looks nothing like mine :P Parax.

Simplest way? http://shop.lego.com/ByTheme/Product.aspx?p=8878 It has a built in speed controller (7 step) and it'll save you money/hassle in the long run. You could use a PF speed controller remote and a receiver too, It's possibly cheaper than the rechargeable battery. As for noise, this greatly reduced if you use a speed controller. I have no experience of encapsulating the motor, but I doubt there would be issues though, as its designed to work whilst encased in Lego! I believe there is a thermal cut-out on it, perhaps someone could confirm this. P.

The Slot looks very much like the newer pieces which have a slot also http://www.bricklink.com/catalogItemPic.asp?P=64179 http://www.bricklink.com/catalogItemPic.asp?P=62821 This slot is a moulding short-cut for the recessed ring that pins snap into. Although it is mainly used on the insides of open structures. Perhaps this original slot was also a moulding issue rather than being functional. Nice find, its good to see rare parts! P.
