This transmission gives a little more than simple two speeds. In fact here we have four speeds (low,low+acceleration,high,high+acceleration). For example to get "low+acc" speed from "low" speed we don't need any gear shifting so model don't slows down before acceleration. In addition we can increase a torque and it can improve flotation or, for instance, works like a handbrake on slopes as shown in the first video.

I've sent a PM to ZED on Doublebrick!

Fantastic MOC! So many clever functions!!! And tractor is surprisingly fast and powerfull. Great work!

Cool idea! i think you'll get much more fun if you'll increase the speed of the model!

In this model i use two variants of RC valves - servo-motor works fast, so i use it for gear shifting (i control it by using RC unit with speed control). M-motor is used for car lifting. Yes, i use all eight channels - 4 XL motors (one motor per channel) and other four functions takes remained channels. Thanks :)

Thanks for model - really accurate and precise work!

Thanks for comments! I'll try to answer :) Yes, i had some doubts about it but lime strips improoved its perception. Now i am waiting for a BL order with other windscreens - maybe i'll create something better when i'll get it! I think the model will be more "square" with tiles... in any case i haven't enough tiles to cover entire model :( Not so dramatically as i expected - XL-motors is a real power :)

Thanks all!!! I use a differential gear as adder - normally we use it as "one input - two outputs", but if we connect one more motor to one of "outputs" than the axis on the second output will rotate with speed equal to "speed of motor 1" + "speed of motor 2". Sorry for my clumsy explanation - i'll find more clear one in technical literature or maybe somebody with better english will help me :)

Hello All! Some time I was out from EB, but I’ve come back with new MOC :) I had short of time that’s why its construction took about two monthes. This is my tuning-version of legendary Ferrari Enzo. The scale is 1:8.5 (length – 58.5 cm, width – 24 cm, height – 13 cm), total weight – 3.6 kg. Design combines various features of original Ferrari, tuning-versions Edo Competition, MIG-U1 and my own ideas. There are six RC functions in it: - moving – 2 x XL; - acceleration – 2 x XL; - two-stage gearbox (pneumatic-controlled) – 1 x Servo; - adders locking (pneumatic-controlled) – 1 x Servo; - steering – 1 x Servo; - clearance adjustment (four large pneumatic cylinders) – 1 x M. The scale is approximate with respect to wheels. Front wheels – 81.6 mm from 42000, rear – more aggressive tires from 8461. The transmission differs from original one. For better playability and transmission load decreasing i’ve mounted AWD. In the same time central differential gear is an output gear of gearbox. Two-stage gearbox allows to drive both on the flat surface and on slight off-road. I’ve mounted two air tanks to decrease switching time. The acceleration is realized on adders (two parallel circuits for reliability increasing). The adders can be locked. Instead of velocity locked adders sums the torque. The next feature of my model is adjustable clearance on both axles (original Ferrari Enzo has only front axle lift). Vertical rods was replaced by shock absorbers and pneumatic cylinders are mounted at horizontal angle. There is an adaptive aerodynamic element in my model – it is rear spoiler that is switched simultaneously with gear box. The model has detailed cabin The movie: Thanks for watching!

One more MOC

Cool model! Will we see some ramp jumps? :)

I really wonder - why do you suggest to exclud PRO builders??? Ancient wisdom says " The only way to become smarter - play with a smarter opponent "...

Very original and light construction!!! Does one LiPo batery power four XL-motors without any problems?

Very high quality work!!! Especially i like smooth lines of all parts of the machine and of course high detalization! This section is assembled from "1x4 slope curved" parts!

Thanks for very original video! One of the Best 8x8 trucks!!!

Incredible power!!! It seems this monster can move with 1:1 ratio - maybe you've tryed this? And these wheels are awesome! Super Truck!!!

Thanks for review!!! I've received my 8862 one week ago (in "used" condition) - it is really greate set! Its front bucket control is amazing. I have 8455 too and i think that its elder brother isn't worse! As for me i like old building instructions because they are not so primitive as modern "one part to step" instructions...

Great MOC!!! Incredibly complex mechanism! And really high productivity :)

I am sorry for posting in your moc topic. I hope moderators will delete my post.

Not "auto" but rather small RC valve:

Wow!!! Exellent work! 100% correlation with original set!!! It should be a technic set too ))))

You can put two BB in your model - the first into chassis and the second - into rotation part. If you'll place driven motors under tracks, may be it will be enough free space for BB - try to combine PF elements in LDD! In chassis you can place four functions - 2-track moving, rotation and blade management (compressor+autovalve) - so no wires, hoses and axes through the turntable.

Congratulations to all Winners! And thanks all who voted for my work :) Special thanks to Jim - you organized very cool and interesting contest!!! 4th - is the worst place that could be... epic fail :(

Perfect work!!! I agree - the engine looks massive... If you were lazy, you would not create this beautiful model! :)

Thanks!
