Two popular nitro models from Mugen Seiki and Serpent go electric

Apr 11, 2014 No Comments by

Two new vehicles that rolled across our desks this week came from two very well-established nitro racing manufacturers – which is why it was surprising that both were electric. Actually, the Mugen Seiki MBX7T ECO isn’t too big of a surprise, since it’s a follow-up on both the nitro-powered truck based on the current IFMAR World Champion MBX7 and the popular MBX6T ECO that preceded it, but current 1/8-scale on-road World Champion Serpent’s choice to convert their successful 200mm nitro touring car to electric power, when they already make a typical 190mm car was something no one saw coming!

Here are Mugen Seiki’s words on the new electric 1/8-scale truck:

Associate Editor Since receiving my first hobby-grade RC car as a holiday present from my father nearly 20 years ago, I've been fortunate enough to meet more people and experience more opportunities through the adventures I've had in the RC industry than I would've ever imagined. I've done it all - from working at a hobby shop, to being a factory sponsored racer, to working for some of the biggest brands in the industry. I've enjoyed each and every one of the dozens of kits I've built, hundreds of events I've attended, and thousands of laps that I've logged at race tracks around the world, and my passion is to share those experiences with other hobbyists so that they may find fulfillment in their own RC careers.
