That's the best idea I've heard yet. That Special edition RC 10.
That would be a good one. Nice collector RC to boot. But not a build that will leave you thinking... man that was a blast. At least not to me. I've never built a gold pan, but I built an RC10 B2, and it was ok. Nothing too exciting about it though until I drove it.
A really fun build for me was the the Axial Ryft. It's just up there on my fun builds list. A monster 2-speed transmission, with big chunky gears, solid drivetrain and massive tires. The cage is fun to see it go together. And all the parts are really high quality. Catch them on huge sales, I would guess very soon.
Any Kyosho Legendary kit is really fun to build as well, but hard to find in stock. If you can find a Javelin... man, there are a lot of parts to that one. So it's a good car to just build in stages and take your time.
Crawlers, either 1/24 or 1/10 can be some very interesting builds, depending on how you mod them. Lots of options there to just get crazy.
Smaller scale can be used indoors. If you have room, the Kyosho Mini Z's look like a blast. Expensive, but probably the best small scale racer out there.
If slow is your roll and you feel like getting (or going) nuts... build one of these little guys...

There are lots of vids on the Orlandoo trucks. Very capable little beasts, but challenging build. Fortunately they are very cheap. But there are upgrades for them, campers, trailers, etc. Just a cool little platform here.
