Maybe to save the cost of an electric conversion kit. The Losi 8ight E is more or less a Losi 8ight buggy with losi doing the work of installing the electric conversion for you and putting in a brushless system and hiking the price up. Buy the RC8B, a electric conversion and build it electric from the get go and buy a nice brushless system instead of the nitro motor. I recommend the Tekin RX8 system. I just dropped one in my Losi truggy and it is insane.
