That car is cool, but not practial. At least the way I drive! I've had both gas and elec. Both are fun and different. Don't ever let anybody fool you an electric will blister a gas motor at almost any kind of racing you do.
The biggest draw back to electric is down time. While you just refill the gas tank on a nitro you gotta let the elec motor cool down a long time before you throw the next battery in it. The lipo's are sick power and you can get 35 mins to 45mins of run time out of a good battery. To be honest to much power to use on a track if you're racing, but a ton of fun!!
