Trial Jeep features 4-wheel drive with fake V6 engine, ackerman steering, 5-link suspensions, opened bonnet and trunk and detailed interior.
This jeep was built on a new concept for me. First the axles are not pendular but with a 5-link and shock-absorbers. The layout of the links of the suspensions is mainly inspired by Jovel’s work. Secondly, I completely re-built the axles to include two options of building : with or without differential. I was boring by the Trial Truck which did not turn because of the lack of differentials so I would like to test it. To finish, the design is based on my previous jeep but with the new panels and at a bigger scale. I have seen that jeep body is more appreciated than classic truck body.
The interior is detailed, for instance with a complete dashboard, seats, V6 engine placed under the bonnet and rear benches. I also include a fire extinguisher, tubular protections, antenna… In fact it is the most detailed trial truck I have done.
Concerning the climbing abilities : they are unexpected and very good. I thought that the differential will always slipped. In fact the suspensions are very good, which enable the wheels to be flattened on the ground. The slipping of the differential is consequently limited. The main advantage is the turning radius, as you can see on the video, it is very small, what enables the truck to have good turning abilities (also thanks to the ackerman steering). The gear reduction is 12/20 20/28 and 8/24 on portal axles. On the video, the battery box is a little bit tired.
I have made pro building instructions using MLcad and Lpub, in fact this was my first lego instructions. As usual, you can buy it for 10€ and then download the instruction immediately.
Here is the complete bill of material in picture file :
But you can also checked it on rebrickable (or make any export you want)
Want to check before if you can build this moc ? The Trial Jeep has been indexed to Rebrickable.com, the webiste which matchs your parts with mocs ! (the first moc indexed to rebrickable !!)
By using the next up paypal button, you will get the pro-building instruction in PDF for 10€.
After your payment, click on “return to MocShop” and wait for the redirection, you will be redirected directly on the PDF file. If you browser can read the PDF, please wait until the end of the download (it can take some minutes) and after save it on your computer. Please Note that this page will be opened only one time so please be patient to download and saves you copy of the PDF. If your browser can not read the PDF, you will be ask to save it directly on your computer. If you have trouble to download your copy of the PDF after payment, please contact me using the “About Page”. Note that you can print it, but not copy or distribute. Many thank you for supporting my work 🙂
