Motorize 8297

[dolittle]

Hi,

I just finished building it, and I am wondering what would be the steps to motorize it, i.e. to allow steering and movement of the car.

I have seen several YouTube movies, pictures, but I am too newbie at this point to make ends meet.

Any body can give some advice how to start with this model, or provide some generic advice that I can use?

Thanks,

Noam

You have these two methods to motorize the Lego Technic 8297 Off Roader II set with Power Functions elements:

(1) MacGyverek's Brickshelf Gallery http://www.brickshelf.com/cgi-bin/gallery.cgi?f=358965 has a set of photos & LDD renders, plus a Parts List:

(2) "Pimped" 8297 (scroll 1/2 way down the list on http://www.bouwvoorbeelden.nl/home_eng.htm to find it). Dutchman "bouwvoorbeelden" wrote,

"Yes, you will recognise this model as the Lego Technic 8297 Off Road car. But this is not a normal 8297. It is thoroughly PIMPED! This car has:

- a complete new roof with Spoiler, Air Inlets, Antennas and Six Rally Lights

- Widened windscreen

- Protective Side Bars and extra Bull Bar at the front

- Exhaust pipes

- A turning steering wheel in a restyled dashboard

- Metallic look with Black details instead of grey

- Transparent motor block

- Two Infrared Sensors in the roof

- Two extra motors for remote driving & steering"

It has an MLCAD file, a movie, PDF Building Guide, and a Parts List.

Thanks - 8297 is the set that got me back into Lego, but I never did any mods to it. Now that I've got the parts I've GOTTA try these...

Hi,

so now I'm on to remote control my 8297 Off Roader. The steering with one M-motor and one clutch gear was no problem.

But the drive motor makes me headaches. I've a similar setup like the first example here. And my gears are sometimes crunching while driving. So I tried to use a clutch gear, but this is to weak and the car nearly moves. The next thing was to gear down, use the clutch gear and gear up again. But that was a lot of gearing, so I only geared down and used a M-motor instead the XL. Now it moves very slowly and also stops very likely if something comes across.

So my next idea is more intrusive. I'd like to use 'Technic Beam 5 x 7 with Open Center 3 x 5' http://www.peeron.com/inv/parts/64179 for the differential.

My question is, how likely is it that the the gears http://www.peeron.com/inv/parts/32269 and http://www.peeron.com/inv/parts/62821 (setup like in 8265 Front Loader) wil crunch in this setup?

What else do you do to prevent gears from crunching in a drive train?

It's not likely at all.

Use a strong framework, preferably those frames you talked about^

@blueShinyApple:

I'll try that, many thanks.

I've now 'Technic Beam 5 x 7 with Open Center 3 x 5' engrafted vertically into my 8297 and put a XL motor on it. It's not fully finished yet, but I've tested so far and there's no crunching while driving

Can someone supply an actual parts list?

I'm trying to order the parts from lego.com, but some of the parts I cannot find.

Thanks
