Um, well, you said 1/8 scale racing, does that mean electric buggies are out of the picture? Does that mean nitro or gas only? A big downside to nitro powered cars is that if you live in a small town without a hobby store you are left with only electric or gas vehicles - no place to buy nitro fuel. If electric buggies are not out of the picture, Armma makes a buggy called the 1/8 scale Talion 6S BLX 4WD Extreme Bash Speed Truggy RTR that has been clocked at speeds exceeding 70 miles per hour in you tube videos! If I were a 1/8 scale man (I am not I fell in love with 1/5 scale a long time ago, sure sometimes they are slower but the size has advantages) I would definitely look at the Armma Talion. In fact the Armma Talion would be my first choice unless I wanted a monster truck. Kits like Mugen and others I would avoid - very long construction times. Murgen and others are definitely not ready to run. You have to build them up from the ground up, and in many cases the kit does not come with all the parts - you have to buy the engine, the wheels, and in many cases other parts. Avoid nitro, go with gas or electric ready to run vehicles, and buy from quality companies like Losi and Armma. With companies like Losi and Armma the vehicles are ready to run and they come with everything even the transmitter (what some people call the radio) and the receiver. All that you need to supply are lipo batteries, lipo charging bag, and the charger.
no matter your choice, make sure you have fun.
