| | | My 8421 crane arrived today and I'm going to give my first impressions. I did a quickie pen and paper inventory that I may try to later key in and submit to peeron (Honestly i've never done an inventory and I'm a bit intimidated by the size of this (...)

| | | | | (...) I must say with respect to the box, the same thing applies for the 8416 set, which is disappointing. Now all I have to do is get 8421, where can I get one delivered to Australia? Cheers, AP. (19 years ago, 17-Jun-05, to lugnet.technic)

Before this the longest axle is 12. Lego once said on their site that (...) (19 years ago, 17-Jun-05, to lugnet.technic)

| | | | | | (...) Hi Keith I got one here in Toronto soon after we corresponded :-) Just started building it today. It will likely take a couple of weeks given the size of this set and my lack of time. It's certainly the most impressive Technic set I have ever (...) (19 years ago, 18-Jun-05, to lugnet.technic)

| | | | | | Well, I just finished building this set and all I can say is WOW!! This supplants the space shuttle set as the ultimate technic building set in my humble opinion. The whole body section of the vehicle is chocked full of mechanisms. There's (...) (19 years ago, 19-Jun-05, to lugnet.technic)

I like how the cable spools itself in and out with the boom extension/retract though sometimes one seems to outrun the other. With the boom up and extended I (...)

| | | | | | (...) I also have finished this set and I also like the boom extension, but the main problems for me seem to be that the boom extension doesn't move smoothly, and the outriggers follow the same pattern as the ones from earlier sets (8862, 8460).

That may be a playability decision. As I found with my (URL) (...) (19 years ago, 19-Jun-05, to lugnet.technic, FTX)

| | | | | | Just completed 8421 myself. Impressions: -certainly the longest technic build I've ever had. -an excellent parts pack -looks very impressive when complete -functionality: vaguely disappointing.

|
| | | | | | One other question regarding this set. Why the new type of motor? It is bigger than it needs to be, not any better as far as I can tell than the standard type (just as noisy anyway), and no doubt added to the cost of the set. It has two places that (...)

| | | | | | | | (...) Hmm - not a lot more torque, but a huge amoutn of additional consumption, and fairly highly reduced efficiency. The 5292 appears to definately be the American SUV of the Lego motor range. I take it that for heavier torque - it is still better (...) (19 years ago, 1-Jul-05, to lugnet.technic)

| | | | | | | | (...) Thanks for the info. Still, I don't see the need to use this motor in the 8421. It only uses one motor, and it is not a very demanding application. They could have used the minimotor easily. It would have been smaller and less expensive, and (...) (19 years ago, 1-Jul-05, to lugnet.technic)

| | | | | | | | | Yes. When I built the crane, I had the same problem. This can be fixed however. All you have to do is attach the extra tubes. (19 years ago, 1-Jul-05, to lugnet.technic)

I will make an assumption (not always a good idea) and say the 2 unused cylinder retract ports should be hooked together with 2 legs of a Tee, then the third leg of the Tee attaced to the unused port on the pneumatic switch. Every other (...) (19 years ago, 2-Jul-05, to lugnet.technic)

What's wierd is that there is actually an extra tee in the set, although not (...) (19 years ago, 2-Jul-05, to lugnet.technic)

I have done this and the air gently flows out and the boom slowly lowers (not too slowly mind you, but it doesn't slam down). I think this is designed to only use two (...)

I've found by adjusting how far the lever is up the hose you can partially block the hose, which would (...) (19 years ago, 2-Jul-05, to lugnet.technic)
