Do yourself a favor and forget the Redcat. Redcats are "low priced" for a reason.
Arrma like Traxxas is sold and supported by Tower Hobbies;a great company.
ECX is sold and supported by Horizon Hobby ;another great company.
You will need parts and support so if you can't get that locally at a hobby shop then Tower or Horizon is the next best thing to a lhs,
There is nothing wrong with brushed motors as they have been around forever. They will wear out eventually, but depending on how they are run and maintained they can last a long time. You can always upgrade a brushed vehicle to brushless at a later date for around $120.00.
If you are worried that a brushless vehicle would be too fast then look at Traxxas as they offer Training mode on all vehicles. This cuts the top speed by 50% and allows you to develop throttle control while learning to drive it.
