Systems tractors and other machinery
1gor replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After one evening of testing I must admit that pulling power is really great, no skipping gear and it pulls very very smooth, but solution of front axle is far from perfect; when turning to the left sometimes gear rack connectors on reduction hit lower 5 x 7 frame and tractor doesn't steer. Also XL motors are to big for such small model (22 studs wheelbase), so I can put battery box inside (chassis is 1 stud to thick). When I try to make chassis stiff enough, then middle chassis part is 10 studs thick (but according proportions it should be 8 studs) to mantain 17 studs width (chassis is always 2500mm wide, so 17 studs in Lego; max width over wheels is 2900mm so some 20 studs which fits perfect). It seems that I'll have to keep XL motors for harvesters and trucks (that I plan in future...) and switch to 2 PF L motors...- 625 replies

42160 Audi RS Q e-tron

Or if you could find someone who needs C+ motors and (smart)hub, but doesn't need the rest (Audi) and use PF elements from own inventory -

1gor replied to keymaker's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
IMHO it has lots of usable parts (excluding PU components in my case); tires are great for front end loaders, hubs are very strong (but have ball joint ) and new short CV joints are blessing (if only I had at least one), new Daytona diffs... -

That was my hope last few years, but I'm not optimistic; they could not release 94.3 x 38 tire (despite having mold with different tread)...so I'm happy that I made compromise solution with existing parts...it is a kind of rotten compromise because there is no space to use new stronger CV joints to connect front axle to chassis- 625 replies

Actually I have 2 frames 5 x 7 and differential is also braced with 2 yellow gears 14 tooth to prevent skipping. I didnt test it with 10kg weights, but it is ok for normal trailer etc...- 625 replies

1gor replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Main chassis structure with partially done rear axle (need to make front part containing PF Servo) ...and tires for proportions. You can see that there is enough steering space even for fat 94.8 x 44 baloon tires Of course Fastrac will have yellow rims. Drive system (with coupled XL motors) will have 40 to 24 tooth upgear, then 14 to 22 tooth Daytona differentials and reduction hubs at end; 40/24 × 14/22 / 5.4 = 0.1964085297 Which give 61.2 mm per Pf motors revolution- 625 replies

Johannes, here is image of internals (2 gears 14 tooth with differential from Daytona) Somehow bricksafe is cropping my image... BTW I have just compared my axle height (with shock absorbers) and bonnet and there is no need to make any change to axle, so later today I could try to optimise middle chassis part with coupled XL motors to fit front (and later rear) axle.- 625 replies

Thank you, next year will be defenetly much better than this one; but first let us celebrate Birth od son of God and try to behave and treat everyone with respect as he was preaching (that is the most important) Merry Christmass to everyone -

1gor replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
It is indeed, solutions with connectors were to weak and they tend to warn out. Internal is not such big deal, daytona differential has at one side axle 2 and at other side axle 4. It is "braced" by 2 yellow gears 14 tooth. I can partly rebuild it tomorrow with light bluish gray frame 5 x 7 if you want Tire 94.3 x 38 tractor should appear in CLAAS Dominator 370 Answer about tire is in this post- 625 replies

1gor replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After some (longer) time, I have something new; thanks to genius @Zerobricks I decided to take another chance for narrow steering axle using (Daytona) differential and planetary hubs, so here is a result Since original tractor has 4 link suspension at front, this axle could be the solution for 1:18 scale Fastrac 8330. Steering angle is acceptable even with wide balloon 94.8 x 44 wheels (no tire rubbing), but with upcoming 94.3 x 38 (CADA) tractor tire it would be perfect (less than 20 studs overall width over tires). Perhaps I would have to lower shock absorbers or hide the more inside bonnet... Real tractor as template... @Jim I don't know if it is appropriate to post link to this post in Axle collection tread. If you find this is acceptable idea, I'll post there.- 625 replies

Axle Collection Thread
1gor replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have tried, but when streagthening suspension arms part of hub where you connect gear rack is in the way so sfeering angle is very very small. @Arie tires 94.3 x 34 tractor are coming in 2024, but there is one catch - not Lego ones Can you post image with dish in other color than black to see how it looks like? Thanks -

Axle Collection Thread
1gor replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
@vascolp that could be usefull, but I have to test how strong it is. I had some experimenting with longer suspension arm https://www.bricklink.com/v2/catalog/catalogitem.page?P=57515#T=C Defender rims are under way, but I need yellow rims, so I'll have to see how it looks to use black Defender rims with yellow 6 x 6 dish (on 94.3 tire that will be available in 2024) That is something we need for about last few years... -
Thanks for help, but I'm looking how to use reduction hubs

Honestly your shrinked models look better than original; here we can say small is beautifull
