In need of ideas and help please! I've got a Tamiya Lunchbox Mini and am in the process of building it. I'm using all the basic standard plastic kit. When I turn the rear R pins (snap pins) the opposite side R pin turns, but the cogs (gears) inside don't. I've checked that everything is tight enough and where its meant to be, as had my partner. When I put my finger in the motor housing and manually turn the gear the rear R pins turn, so they're obviously connected, but I don't want to put the pinion gear and motor in if the rear wheels aren't going to work. I also don't want to completely take everything apart if not necessary. Any advice please?
