Formula Off-Roader Motorized

[dagupa]

Hello.

I'd like to present my latest Technic project. This a modification of Lego set 42037 Formula Off-Roader.

The goal was to build a motorized version without loosing the feeling of the original. Because of that, my main constraint was to keep the seat, since that seems to be the preferred place to put some of the Power Functions components. I decided to change the motor for a V6 version because it's shorter and it allowed me to place the servo under it while keeping the original ground clearance. 

The model requires 561 parts, including Power Functions. The Lego set and the Modification share about 75% of the parts. 

I upload the building instructions and inventory to Rebrickable, in case someone want to give this a try. You can download the instructions from dagupa.net

UPDATE: Axle was missing from rear wheels. Now fixed. Uploaded 21/12/2017
Pieces added: 2x Technic Axel #3 and 4 CV Joints

 

I'm happy with the final product. I think it looks like a deluxe version of the original.

 

It also performs well. In the video I used a V2 receiver and 8 rechargeable batteries.

 

 

Thank you for your time. Feedback and suggestions are always appreciated.

Nice PF conversion.  You've managed to keep the looks and identity of the original set very well.

My favorite set, I love seeing these MODs of it. Great job on this one, the performance is good!

Another very well executed RC MOD of 42037... I think that's all I need to say.

I wonder how many PF MODs there have been to 42037? It feels like it’s one of the more popular for this type PF MOD.

Thank you. The most difficult parts was to keep the original seat because it takes a lot of space.

Thank you. The V2 Receiver managed to live up to the expectations. I used 8 rechargeable batteries to get about 9.4 volts.

Thank you. I like this set a lot, too. I think it's weird that you can still get it with great discounts. I bought the last one a couple of month ago for US$30 at Walmart.

I think so, too. It's a relatively cheap set and it comes with full suspension. It's not heavy and the box art begs for a motor.

I’m not usually a big fan of PF conversions. But, I am really tempted to join the fun with this set.

Very nice mod with PF motors :) It's pretty interesting to see how people independently come to a similar solution, e.g. swapping the engine to a V6/V8 because it is easier to fit the Servo (and obviously to look more badass  ). I even had a similar placement of those blue panels next to the engine. I agree it's a great set to easily motorize, the only weakness is the CV joints - they cannot handle higher speed offroading.

That is something that have amazed me, too. It's always Newton vs Leibniz. Until you realized they both arrived to the same destination through different paths. Enough about religion ;)

I've been trying to make a 4x4 version of this set, but the CV Joints just don't work with the Steering Portal when the frontal suspension goes down or up over the range -10 to 10 degrees. Which is good for a racing car but totally worthless for an off-road vehicle.
