RC Metal Transmission Center Gearbox Case with Gear for FMS FCX18 LC80 1/18 RC Crawler Car Upgrades Parts Complete Gearbox Transmission Case for FMS FCX18 Accessories (Red)

love it. its been a bulet proof to all my builds. quick solid and responisive. I'm very particular on my parts but this is a must on all four bolt 1/24 1/18 parts... love it

Fits and works great . Great support. First one I got made a ticking noise they had me send it back and sent me a new one with no problem and no shipping charges.

Read some other reviews about fitment/alignment issues, and was prepared to do some fiddling to get everything adjusted properly.Either I got lucky, or this thing is perfectly cut, but I had no issues at all getting this installed and set up!I did open it up and add some more grease, but otherwise it bolted right up.I paired it with the injora 180 pro motor, and wow this setup RIPS! It's also quite a bit quieter than the stock plastic gearbox was. (I had metal gears in mine and it was really noisy)I've been beating on it for a few months and it's held up to all of it.The metal housing sort of acts like a motor heatsink which is a plus. Not to mention that it looks really cool too.Can't recommend this highly enough, don't mess around... GET THIS UPGRADE!

The media could not be loaded. Installed on my FMS FCX18 LC80. I’m rating this 4 stars even though it’s absolutely amazing! After I mounted the motor to the trans I plugged it in and it would bind and not spin in either gear. I had the same issue with an almost identical trans from generic which I returned due to binding. I bought this one because it came with the aluminum servo mount and had hopes the motor wouldn’t bind with it, but it did. If I slightly loosened the motor to trans screws it would free up and spin. Obviously you can not leave the screws loose. So what I did was left the motor loose and plugged into the controller and in first gear lightly applied throttle while evenly slightly tightening both motor mounting screws while the motor is spinning the flywheel, until tight and motor still spinning the entire time. Stopped the motor, then tested out both speeds and it works perfectly! I also opened the trans case and applied Mercedes Benz wheel bearing grease to all gears which are brass, and greased the motor to flywheel gears and reassembled. This is all very easy to do with the right tools. Took me about 45 minutes total including the time to figure out how to make it work. Hope this helps. If you follow these instructions it will not bind and it does fit and work perfectly. Shifts smoothly, adds weight and is quiet. Looks cool too! It did come lightly greased, I felt it needed more for my peace of mind.

***This is the one to buy***If you never want issues with changing gears, this will never mess up like stock. Extremely durable, perfect fit.100% in all areas

The media could not be loaded. Shipped fast , some what east to install, I did resort to Amazon photo to see how the servo mount fit on. The gears were greased up. My buddy said he had to grease his. Two speed works great. Nice upgrade finish.

Swapped the motor onto the new transmission and the gear from the motor binds with the transmission gear. Doesn’t work unless I loosen the bolts holding the motor to the transmission. I can’t leave the motor attached to the transmission loose. Looks like it’s getting returned.

fits great in lc80 1/18
