One thing that was fun for me about racing back then WAS the brand love and hate. The fact that the cars on the track weren't all the same 2 cars with the same 2 esc's... made racing FUN!!!
Each car had its strong and weak points and each driver needed to KNOW that car.
I think 2wd was sort of all RC10's and Ultima's but 4x4 had Kyosho, Yokomo, Schumacher and even a few Tamiya running.
Some were ultra fast and broke easy, some between, some were eay to repair, some were nightmares. Each car and each driver had a different way "they" were going to win that night.
Ultimately it will come down to driving skill in the A-main.
A well built and maintained "race-grade" r/c shouldn't have a lot of difficulty making it through a couple heats and a main imo.
At the end of it all, the differences in almost ALL those cars made me love SOMETHING about each of them.
In many cases, I'd love to own and run them still today. Did I mention I tore down my Optima Mid for total rebuild???

I don't think I'd recommend this to someone starting out. The chassis is bent. Shock towers are tweaked and a few other issues that would prob ruin a "noob's" day.
There are other things too. Like to start, I don't have intructions for this thing.

I don't really need them for this but on a different car I might have problems.
With a new to you, used car, a person might not be aware of certain things to look for and replace. Each car has its own "wear items" that need regular checkimg on.
I still think your Tekno choice is perfect!!!
