Errr, dont forget 1/8th Nitro, where Losi are most definately up there with the very very best.
RC isnt just 1/10th electric; yet this guy just rules out Nitro with one swooping statement?!
In fact, I would say that Losi are a Nitro racing company - electric is very much secondary to their success (at least in the last decade).
With short course and now the 22 they are moving back into electric, but right now, I dont think there is any rivalry to speak of between Losi and anyone.
