Best,If you want the best of the best and money is no issue then get an Elcon fourteX. https://www.elcon-models.nl/en/ for offroad or a 'mecatech', or 'genius' https://www.genius-racing.com or 'harm' https://www.hrc-parts.nl/en/cars/ for your on-road needs., As dougstar mentioned then MCD is also absolutely top end and their platform is very clever and can easily convert from off to on-road. So you can have two cars in one and then just change a few bells and gearing ratio to go from one to the other.
Limitless is the fastest RTR around but it is meant for speed runs. I think you will get more fun out of its brother the 'infraction'. It is at any rate hard to go wrong with ARRMA as a brand. They are the cool kid in class, right now. If you don't mind putting things together then 'tekno' is a brand with some solid RC's under their belt but they only make kits. Thts off the top of my head right now.
thanks for the information !!
everything has become a lot clearer.
"Thrasher" certainly thanks for the links a lot of positive info that I can continue with.
MCD cars, genius, mecatech and Harm for electro I will investigate this further.
Now thanks to you I know that there is much more than Fg models.
I will come back to this later and will show what I will enjoy.
Thanks again to all.
