[MOC] RC Caterham & Lotus 7 powered by RC Train Motor

[JamesJT]

I made a RC Caterham and a Lotus 7 version using 2 RC train motors. I borrowed a steering design by Anto (from his Ken Block Fiesta) that makes the car lift its inside rear wheel when cornering. It means the car can do without a differential and produce roll induced oversteer.

The Lotus has narrower front and rear axels.

You've put all the blue panels into good use here. It looks very nice. Are motors hard coupled?

[KamalMYafi]

That is very cool (as usual)! I haven't seen (cool) cars used a train motor!

I like how you did the front arches of Lotus (?) , they look very good .

You have inspired me .

[Attika]

Seems to be a real fun. The bodywork is jaw dropping. Again.

The motors are hard coupled. See 1:06 min.

Really impressed from performance. Great idea and cute clear design of the cars. Good work... ;)

I'm loving all the blue. I'm impressed with all the shapes you are able to get with the five blue panel available. Great job on the steering as well.

Wow! Lovely and quite accurate replicas, great!

[JamesJT]

Thank you all for the comments. I had a blast building and testing this.

After many attempts, this turned out to be the strongest version;

RC Train motor coupling by James Tillson, on Flickr

It has a 12L axel, 2 axel and 16L axel to couple all 4 outputs together but I needed the clever steering of Antos Fiesta to make it work without a diff. It is also an odd number of studs wide which is better for studless technic models.

The Lotus only happened because I finished the Caterham and realized I hadn't used the 18944 panel.

Wow! Lovely and quite accurate replicas, great!

I could have got closer but I didn't want to add weight. Using the blue11954 curved panels as part of the chassis meant I could remove 6 beams but it also meant I couldn't have them taper in toward to nose.

I would have liked to put the IR receiver a bit lower too.

I really like it. This is something to give to the kids to have fun driving around.

Any plans for instructions?

[Zerobricks]

Good looking and speedy. And lets not forget its blue, one the currently rare technic colors.

[Leonardo da Bricki]

Nice! I really like the long front arches on the Lotus. And you have great performance. How is the front axle mounted?

[JamesJT]

IAny plans for instructions?

I will add a LXF later today.

... its blue, one the currently rare technic colors.

Blue is not rare in my house. I didn't even have to pinch parts off my Rebrick Porsche.

Credit where credits due, Have a look at Anto's Fiesta.

This is really cool!!! Great use of those train motors...you are really in to this I can see...haha...!

[JamesJT]

I added the LXF to the OP.

[TheMindGarage]

Impressive, and incredibly fast!

[KoolJBlack]

Really cool Caterham! Thanks for sharing an LDD. I was inspired enough to make my own.

...Sadly, I lack train motors (or most power functions for that matter), so I made one with fake engine and steering instead!

I've got a non RC LDD for those interested here.

Looks good without RC! BTW, thanks for sharing the LXF file! Because i don't have that "Train Motor" too.

That's brilliant. Do you have HoG steering?

[KoolJBlack]

Glad you like. It doesn't have HOG steering, instead, the steering wheel is directly connected to the front wheels (works great!):

it's so cool to see more people using train motors, they're so useful and underappreciated! they look great, looks just like the real thing, great use of all the new panels in recreating such an iconic vehicle!
