Painting them is easy, painting them good is harder. Just remember since you're painting the inside you have to paint backwards, like on Bumblebee, the first thign I painted was the Autobot logo and then the black stripe. Lastly I painted the yellow.
So, whatever would be your last thing to paint normally, is your first. You can paint the outside, but then the paint will scuff. Also when you do paint the inside you get a really glossy finish because of the lexan. You can make it matte by hitting the outside with flat clearcoat.
I liked my rustler a lot, but it drove far too different than my Stampede. Closer to my Slash. I'm much happier with 2 Slashes.
I have been looking at the rally car Traxxes has. I've wanted an electric 4Tec for a while. And hope this new thing is a good replacement. It does look pretty sweet. Traxxas - Rally (#7407) - Overview | traxxas.com
When I get some money saved (after I get my Nexus 4) I'm hoping to upgrade one of my Slashes to a 4-wheel drive. I originally wanted a Revo but couldn't afford it. Was always bummed the Slash was only 2 wheel drive.
Looking at the Rally on Tower Hobbies, they're running $439 because of the Velineon and controller. I may buy all the parts and build my own with a brushed motor and ESC. I have an extra receiver and controller.
That is sweet looking. I see that it's 4wd. I settled for 2wd on my Slash.
I wish now I had went ahead and bought the the 4wd model. I've read that it corners so much better. I bet the Rally rocks.
I was looking at the E-Revo Traxxas - E-Revo Brushless (#5608) - Overview | traxxas.com
With the larger motor and 4wd it should be impressive. However, it's pricey and takes two li-pos to top out. It's on my wish list... but so are so may goodies.

My uncle flies RC planes. Mostly made of balsa wood, with both gas and electric motors. Unfortunately, he's getting old enough where he can't live on his own and was planning to get rid of (or more likely sell) his massive plane collection. I wish I could take in all of them, but I asked him to hold on to 2 or 3 of his favorites (at least 1 gas and 1 electric) and I would keep them and try to learn to fly. I should be able to pick them up when I go north for Thanksgiving. I just need to find a spot to put them.
He had about 20 planes. Most of them have 5-6' wingspans. All assembled by hand. Not those kits you slap together in 20 minutes they now sell.
My brother-in-law got into plane building/flying a few years ago. He was building them out of some kind of corrugated plastic signboard stock. His planes were very cool but his flying skills lacked some. I watched him crash a couple of his projects lol. Flying is much more difficult than driving a car or truck... even at sixty mph. I can't blame you for wanting some of your grandfather's planes. It would be fun to fly them and a great way to remember him always by sharing his love for the sport/hobby. I'd want to start out flying/crashing some cheap snap togethers before I attempted flying some of his treasures. If you have the opportunity, snap some pics of his work... I'd love to have a look.
