[WIP] 1972 Winnebago Brave D20 - BrickFair VA 2019 Submission

Recommended Posts

Posted (edited)

Hey guys, here's a MOC I've been planning to make for quite a while now: the 1972 Winnebago Brave. RV's have gained virtually no attention in the world of Lego Technic, so I'm pretty excited to see what I could accomplish in this MOC. I also plan on bringing this MOC to BrickFair Virginia this summer.

I decided to do a Winnebago for this project because my friend back in Iowa has a passion for Winnebago RVs. Out of the many Winnebago RVs out there (Cheftain, Indian, etc) and model years, I settled on the Brave because her favorite model is the 1972 Brave. Despite it being an unusual subject for Technic, I nevertheless plan to include all those "traditional" Lego Technic supercar functions on this MOC, such as steering, suspension, and transmission.

Currently, the chassis is about 2/3 of the way complete, with most of the mechanical features now in place. In between the seats is a fake V8 engine connected to a massive 4-speed transmission shifted using the rotary catches from the 42083 set. The transmission is shifted using the paddle to the right of the driver's seat - it uses a rubber band mechanism similar to the one on the 42083 to rotate the catches 90 degrees for each press of the paddle. The gear ratios are 2.08:1, 1.33:1, 1.25:1, and 1:1.25. Both axles will have live axle suspension, and the steering mechanism includes a working steering wheel.

This MOC will have no motors, and it is in fact my first MOC without any motorized functions. To increase visibility of the mechanics, I plan on incorporating a removable body and floorplan to expose the chassis down to its bare bones. I may also include a customizable floorplan to increase playability (like the Creator Ford Mustang set with all its customizable features). I may also include some accessories to go along with the model, such as a canoe or kayak.

PS - shoutout to my friend for providing me brochures of the RV. Had all the information I needed to get the building process going. :classic:

UPDATE 6/26/19

Hey guys, I've finished the chassis of the Winnebago. I've decided to go with the D20 as I found out the chassis was longer than I thought. I shortened the chassis from the previous update a bit (note the knob wheels now being used to shift the transmission instead of the bevel gears). I also removed the HoG steering, which I didn't want to, and have steering only be controlled by the steering wheel (like in the 42056, 42083, and Mustang sets). This was because the steering mechanism had way too much play in it due to all the axles and gears transferring motion from the back of the model (where the steering knob was supposed to be) to the front. The axles and gears were an eyesore as well, so by eliminating the HoG steering it really cleaned up the surface of the chassis. It will be difficult to steer, of course, but I plan on incorporating a removable body/floorplan so the steering wheel should be easily accessible with the body removed.

A challenge in building the rear 1/3 of the chassis was that the live axle required a "bridge" in the chassis. As a result, that area had a tendency to bend, especially with the shock absorbers exerting force in that area when the suspension is compressed. To reinforce it, I added a second layer of beams and some diagonal ones as well. The area immediately above the shock absorbers has even more reinforcement. The reinforcements virtually eliminated the bending tendency.

If you guys have any suggestions for me, please let me know.

Awesome!  
Have you thought about gearing the fake engine up so it spins faster? 
Makes great noise when it's moving.

Thanks!

As for gearing up the fake engine, I don’t need to do that as 4 different speeds are available through the transmission.

UPDATE 7/7/19

Hey guys, I've finished the floorplan of the Winnebago. The floorplan includes a dining table, two benches, a bed, a range and sink, and a step well. All 5 attachments are removable and are able to stand upright when removed. Honestly, this past week I felt like I built several small MOCs lol. :laugh:

Note the four 45 degree double bent beams attached to the chassis - they will be used to attach a "cage" for the body that keeps it firmly bound to the chassis when attached. The "cage" will also be removable.

I plan on submitting this MOC to Lego Ideas when finished. It will be my first submission there.

any plans to make it RC? it looks dense so i imagine not but still great work so far!

also can we get a pic of the underside? im curious how you did the suspension setup because proper live axles are a tough thing to pull off

No, it won't be RC. I wanted it to go in line with the latest Technic cars (such as the upcoming Land Rover) and they all have similar functions - steering, suspension, transmission - all manual.

I might show the underside in the video when it's finished. The live axles are similar in design to those on the 42043.

I love old Winnie’s so am enjoying watching this build progress. Growing up I promised myself I’d tour the World in one one day but life (and a very large tree *oh2*) got in the way.

Lmao I realized that. Problem is I’m gonna have to build an entire structure around it that spans the entire height of the vehicle. For a MOC that’s focused on mechanics, I didn’t feel like going that far.

Also why there’s no wardrobe either lol.

Do you guys have any suggestions on printing custom stickers?

I have to model the “W” pattern and the “BRAVE” logo using custom stickers.

If any of you have experience with printing custom stickers, please let me know.

The stickers, especially the “W”, would have to be precisely printed to scale - the width of which being the height of a standard Technic beam. The color would have to be precise to.

This means I’d have to get them custom made for me.

@JLiu15 Personally always printed on a home printer (crappy paper cutouts with simple names/numbers... needless to say color and size fidelity is lacking) but Nico71 has used this Bricklink seller's custom stickers on his s2000: https://store.bricklink.com/fwsticker&utm_content=globalnav#/terms

Loving how the model is highly detailed (fantastic furniture) and functional, looking forward to the finished build!

Thank you! I’m currently making digital designs of the bodywork on Bricklink Studio. I’m also ordering parts in dark blue from BL as I will be making that the secondary color of the body.

Sorry to be late to party but I really like all that details like bed, sink ... It is very realistic and interesting build...as for stickers; I'm not such fan if stickers, so I would probably rather use Lego tiles with letters to for a word of phrase I want to be on vehicle...
