I've had a bunch of their vehicles, some of my favorites are the TR-MT10E, Landslide XTE, and the rampage line. Its also nice to see that they are going to make their own models with the release of the Gen 8 and the Gen 8 AXE, I hope this keeps up and they become a fully independent company someday.
[Edit] Redcat also has a really good customer support team, if you have issues you will get a replacement part or even a new vehicle, and if you don't have a warranty they will help you as much as they can. Even though a lot of shops don't carry their parts, yet, you can find mostly everything online for an affordable price.
