I own the eb. Never driven a b74 or any ae for that matter. One thing to consider is that this platform is Teknos first attempt at 1/10 scale.(and its a pretty damn good car) The development of the eb started 5-6 years ago. They'res only 6 people in the company.... They definitely do the r&d..From the time they were first developing ebuggy conversions till today is not a very long time considering the amount of success they have achieved. Seriously. I dont run 8 scale but Im a huge fan. They're truck is a monster. Also with the new 2.0 buggy they are really pushing the limits of design. In fact, thats one of their main focuses. To be different. They've campaigned in the uk and have a decent size team there as well. All 7 -8 years. Daniel Lewis is a very forward thinking business man. He emphasizes on developing his young drivers as he believes the youth is the future of this hobby/ sport. As far as eb410vs b74, cant say, but what is evident is that Tekno is very successful in the local levels, and developing as a company and if the eb410 cant hang with the b74, consider it another way. Teknos first 1/10 scale platform vs 50 years of experience.
