Yes it is the same wheelbase length as a ue thunder-mono. I have a full blown ue thunder-momo-vbs and can tell u tjat the G4 is the same length. No need to buy a mono like everyone who owns a egular gmaxx chassis. Not only this but i can run up to a 50t spur. Much better options than being stuck with a 44 spur.
Cool... the extra bit (mono) does help to stabilize the truck though... I notice this when I drove my FLM chassis with a mono against my friend's G4 Chassis...
I found that the G4 was a little tail happy being a shorter wheel base than the FLM/Mono combo... Just a person opinion based on observation ....
