I love my 1/8 Ramiantor MT, but that's by Losi.
I've heard of GV Models, but it's not that big a name.
Your call.
Problem is, IT WILL get broken. When it does, can you locate the parts?
How easy is it to work on?
How about a Losi 8ight?
How about the brushless 8ight?
Why not just go for a Savage, T-Maxx, Revo, LST - big names with loads of spares (and hop-ups unfortunately !!!! :lol::lol::lol

??
I'd go for a known brand with good spare parts availability, particularly as it's for your lad, who won't accept downtime, even if it's his fault
