Hi all,
I'd appreciate it if you could give a newbie some advice before i start chucking money in the wrong direction...
I recently bought an Absima AB3.4 in kit form as a "quarantine project" along with a goolrc 4300Kv motor and 60A esc combo from ebay and paired it up with a 45C 2S lipo. I'm experiencing bad low speed cogging with it to the point that it can't even pull away when sat on short grass. A gentle kick up the arse to get it moving and it goes screaming off, acceleration is very strong and responsive, plenty of power on tap. I'm running it on a 23 tooth pinion, I saw a youtube video by Birmingham GT RC where he was running pretty much the same setup with a far larger pinion with no problems, so i can't believe i'm overgearing it. Mesh between pinion and spur looks fine to me, no tight spots in drivetrain etc.
I'm thinking it might be a duff esc but I'd welcome any other ideas.
Thanks
