is the mugen mbx 5 raceworthy as a electric?

The tekin buggy motors (1200Watts) are a little weak compared to a Castle 2200kV motor which is standard 1500Watts motor. They heat up and have lack of torque and efficiency in 1:8 buggy. If you want absolutely a tekin combo, take the truggy motor instead. Note that tekin truggy motors are little less powerfull than the Castle too...
the mbx5 races great with electric motor ;)

Are you kidding? I'd have to say that the Tekin 1900 is THE BEST motor for racing w/ 4s in a Buggy. I've been using it for almost a year now with ZERO issues. It does not heat up the esc enough to ever turn on the fan, I get easily get by with a 4000 mAh pack in races where others can't even finish with 5,000 mAh. Temps are usually between 100 and 125F and have never reached 140 with 4s. In comparison, my the min temp on my 2650 is about 140F.

Speedy BL, yes, but with the tekin truggy motor, your temps would be between 80 and 100F for the same top speed, with the increased efficiency...
Here in Europe we have tracks with long straight parts and very hard small curves, and the tekin buggy motor are just in lack of power compared to the truggy motor or the Castle 1515... We can't gear it for more 35mph unless it overheat, that's why we take bigger motors to keep temps good.
Maybe your track is not as difficult for your setup as ours...
More over, the truggy motors weights only 40 gramms more and is not more expansive... and he will be able to use it later, if he buy a truggy...
Always better to have power in the hand and to not use it than the contrary.
