LEGO Technic Liebherr R 9800
The LEGO Liebherr R9800 is one colossal model, yet due to several great functionalities, also very elegant! A fun and pretty straightforward build experience, with excellent final visuals. More than 4000 pieces makes it fairly valuable regarding cost per piece ratio. Most impressive feats are its motorized functions, powered by two battery hubs. The model is controlled from the Control+ bluetooth app, and (Once connected!) it works beautifully. Have patience though: The connectivity is bland, to say at least, and frustrating loading screens to be expected. That said, it won’t change the overall experience: The LEGO Liebherr R9800 truly manages to impress. Highly recommendable for all LEGO fans!

I personally thought that $500 (taxes included) was way too much for a set like this, so I poked around on eBay and found someone who was selling this set for about $100 less. There was no box but the bags were still factory sealed so I didn't have to worry about any missing parts or anything like that. I was a little worried at one point cause I couldn't find the two sticker sheets but they somehow managed to get stuck inside the one of the manuals and they just fell out. It wouldn't have been a big deal since that's nothing customer service can't handle, but it would take longer than usual to resolve since COVID-19 is slowing things down it bit.
The set itself is absolutely amazing! It came out way bigger than I expected when I finished bag 2 and when you look at the picture of the real machine at the end of book 2 or even look up a picture of it online, it's kinda hard to tell spot any differences between the two different versions. The details are in all the right spots; retractable entry steps, oil canisters, dual exhaust, air duct fans, fake hydraulic lines, etc. it's amazing no matter where you look at it. It really doesn't seem like this is the biggest technic set, but it certainly is the most beefy compared to the Bucket Wheel Excavator. (42055)
Although there is no bonus model for this set, I'm okay with that considering that once you finish this set, you probably won't want to take it apart until you want to sell it which let's face it, that probably won't happen for a few years. The overall play experience was just as amazing since you feel like you're operating an excavator in real life (boom & bucket on the right side; stick & swing on the left) and you can learn some advanced maneuvers like pivoting the bucket, spinning in place, jump turns, and more.
Another cool thing is that since you are gonna calibrate the set when you launch the app, it knows the limits of the linear actuator so they'll stop about a millimeter shy of the point where they would normally make that grinding noise, which is good since that'll help the workings inside the actuators last longer. If you're really against the wall on getting this set, it really is that good despite what others say. Disregard any reviews that aren't 5 stars cause those people just got unlucky.
My only complaint is that the set struggles to turn on carpet and I know it's because of those clutch pieces that are in the drivetrain. It has no issue going in one direction but that's something to keep in mind if you do get this set.
Overall, very awesome set. It's a blast to play with and you're gonna get your money's worth no matter where you buy it from

One of the best, biggest LEGO Technic kits!
One of the best LEGO Technic kits there is! Great build entertainment and the many motorized functions are astounding, all controlled by your smartphone. Its complicated, so pay close attention to the two instruction books and make use of the online, animated instructions. It is massive, just like the real excavator it represents, and is as beautiful to display as it is fun to operate! This kit has been retired by LEGO, so it is much sought after and the prices are rising.
Painfully slow, yet entertaining
A compelling build with precise instructions. Set up of the Power up hubs and motors with your smart phone (iPhone 11 in my case ) relatively easy as long as you follow the instructions on when to do this.
The model itself is a marvel to look at especially if big diggers are your thing Detailing (hand rails, hydraulic hoses and drivers cab) add to the look. Stickers as usual are a pain, be careful with the 9800 sticker that goes on the lower jibe, this can easily be slightly obscured during the build if placed central on it's panel. Place this one higher up.
Building the gears and drive trains are very reminiscent of the old meccano (when it was engineering based) though a bit slack in the housings for power operation making the model annoyingly noisy in this department (turning up your phone for the machine sound effects or wearing ear defenders masks this )
Perhaps for these kind of models adding bearings and some form of grease would fix this annoyance in them.
The greatest aspect of the model is its functional attributes The digging, jibe lifting, body rotation and bucket swings are most fun and entertaining But the track operation lets it down Very clicky as it jumps the drive sprocket on full turning (worrying you into knowing your excessively wearing down the gears), works best on smooth wooden floors Slightest bit of carpet will start the worry when turning.
Comically its slow in a scale speed way, it will take approx, ten minutes to pick up a dropped lego piece and hand it to you. its a lot quicker to just get off your chair and pick it up yourself. Yet it would make a perfect running partner for a tortoise.
