The Kyosho Monster Kruiser USA-1 GP 1/8 ReadySet Nitro Monster Truck pays homage to the classic Nitro USA-1. This truck set the standard for Monster Truck power and performance when it was released in 1990. 30 years later, the torch has passed to the latest Nitro USA-1, which outperforms the original in EVERY respect. Yes, it's that much better - and this awesome Readyset package is built for you! Add your batteries, nitro fuel and glow plug heater and you are ready to run.
It's comeback-time for the USA-1, with modern chassis and drivetrain technology, upgrades unique to the USA-1 throughout, with an ultra scale body finished to display-model standards. The iconic American flag graphic emblazoned on the body brings back memories of the original. The chassis features shaft-driven 4WD and 5-link suspension based on the Mad Crusher 2.0 & FO-XX models. Most of the suspension components have been uniquely upgraded and reinforced to handle the powerful KE25SP2 engine, and the rigors of monster trucking. A 3-speed automatic transmission produces dynamic acceleration, which is enhanced by a unique suspension system to produce "scale" running characteristics worthy of the prestigious USA-1, and make you feel like a monster truck king.
Features:
- Pre-assembled chassis with R/C system installed and finished body. Includes pistol-grip Synchro KT-231P+ transmitter.
- 5-link suspension in combination with shaft-type 4WD delivers exceptional stability over rough roads
- Equipped with waterproof KS5031-09MW servos that incorporates durable metal gears
- Ultra-realistic scale body has been recreated under license of USA-1, including the signature color scheme
- Optional LED light set shines bright with LED head & tail lamps and rooftop fog lamps (not included)
- Equipped with KE25SP2 engine with easy needle setting
- Includes break-in ring to get the engine safely prepared for harder running
- Gleaming polished tuned muffler is equipped as standard
- Front center drive features a telescopic universal shaft to ensure high drive efficiency and prevent shaft dropout issues
- Optional 4WS (four wheel steering) increases turning power. A wide range of other options is also available (not included)

Kyosho Monster Kruiser Nitro USA-1 GP 1/8 ReadySet Monster Truck
I did not buy this from Amain, I bought it directly from Kyosho America, but I want to share this review. I have had this truck for over one year and it's a GREAT truck. But.... the gears in the 3-speed transmission are very cheap and they wear down quickly on the insides, causing all kinds of trouble, include a failure to shift. They also strip teeth. After receiving some replacement gears from Kyosho, the problem continued. So finally, I purchase a set of steel gears and steel clutch Bell from a company called GTB racing on eBay. Once I switched to the steel gears, the transmission has been indestructible. Hopefully Kyosho will fix this problem for new editions of the truck. Anyway, now I totally LOVE this truck!

Kyosho Monster Kruiser Nitro USA-1 GP 1/8 ReadySet Monster Truck
Transmission problems since the 2nd tank of break in. I contacted kyosho and they said it is a known problem with the one way bearing slipping causing it to all of a sudden grab and strip/shock 1st gear. They sent me a new bearing and hub but the problem continues. This is in no way a reflection of amain hobbies they have always helped me out. Unfortunately, kyosho fell short on this for me and after replacing everything they said to, it’s still a 500$ paperweight.
Buyer beware kyosho releasing products that they know are defective from the factory… but hey maybe you’ll have better luck than me so far in this nightmare.

Kyosho Monster Kruiser Nitro USA-1 GP 1/8 ReadySet Monster Truck
I purchased this truck mainly as a collectors item, and a shelf queen. The body and graphics are just so awesome. But, it had some issues right out of the box. The hood decal was scratched in a few places. The tuned pipe is scratched also. And the chassis parts had some weird, mold or fungus or something on it that I had to clean off. So I give it only 4 stars for those reasons.
Also, it seems this truck has some serious problems with the transmission. Many videos on Youtube and posts on Facebook are describing the trans failing after a very short time. In some cases, only one or two times of running it. The one-way bearings are failing, spur gears are stripping, and the mainshaft is getting galled and scored. It is not at all like Kyosho to have these sorts of problems. Perhaps they got a bad batch of parts or something, and they really need to take a deep look at their production line and solve this issue.

The truck is beautiful but built badly with lack of parts. If you buy make sure it stays a shelf queen. There is a reason why all the videos for the truck on YouTube are a year old...they've all broken or can't be repaired

BROOOOOOOOOOOOOOOOOOO I mean it's a great truck but THE TRANSmission is the problem IT RUINS THE EXPERIENCE
Why did Kyosho release the product while a certain system in it has a major issue? Was it like releasing the new but unfinished Call of Duty, trying to get it done before the short deadline comes? I PAID MORE THAN 500$ FOR THIS

A darn good grass burner!!! Make sure you enjoy exactly what it is! A solid axle lifted 3 speed amazing looker! In the field is where it dominates. Do your passes and turns and driving, wheelies for days!! The body is a big set back to realism and durability. So it’s not beatable but mad crusher parts should be interchangeable!

Kyosho Monster Kruiser Nitro USA-1 GP 1/8 ReadySet Monster Truck
I bought this truck after lusting after it for over a year. I was NOT DISAPPOINTED!!!! Holy cow this thing is so cool! This is my first Kyosho and I was blown away by all the detail on the body and truck. Fit and finish seemed just as good as any Traxxas or Arrma, but I know it wasn’t made to take that kind of abuse. I bought this to mainly run on the street and not send it to the moon. It was really easy to start and get broken in, it idles amazingly too. I did have to turn in the idle screw from factory in order to get the correct idle gap. I would definitely buy another one of these truck in the future and the .25 motor is a BEAST! This has quickly become my favorite RC among my other nitro and electric cars.
