FAQs-Engineering

Q1: What types of construction vehicles are included in this collection?
A: This collection covers a range of construction and engineering machinery, including excavators, bulldozers, backhoe loaders, dump trucks, crane trucks, and asphalt pavers — all reproduced as detailed diecast scale models.

Q2: What scales are these construction models available in?
A: Most models in this collection are produced in 1/40, 1/43, or 1/50 scale, depending on the specific machine. Exact scale and dimensions are listed on each individual product page.

Q3: What's the difference between the "Static Models" and "RC Models" categories?
A: Static models are non-moving display pieces designed to sit on a shelf or desk as a collectible. RC (remote control) models, such as our 13-channel RC excavator, are functional toys that can be driven and operated, often including additional features like a working bucket, sound effects, or a water spray function.

Q4: What material are these construction vehicle models made from?
A: Most models combine diecast metal alloy for the main body with plastic for certain functional or detailed parts (such as wheels, hydraulic arms, or buckets), giving each model realistic weight along with durability for handling.

Q5: Do the static models have any moving parts, like the boom or bucket?
A: Some static excavator and crane models feature movable elements — such as a rotating cab, extendable crane boom, or articulating bucket — that can be manually posed for display, even though they are not motorized. Check each product description for specific movable features.

Q6: How does the RC excavator work, and what's included?
A: Our RC excavator is a 13-channel remote-controlled model that includes a controller and batteries, and it features realistic functions like digging, rotating, and in some cases simulated water spray and sound effects. Please refer to the product listing for full specifications and what's included in the box.

Q7: Are these models toys for kids or collectibles for adults?
A: This collection serves both audiences. Several listings, such as the RISOPEN construction truck set and the RC excavator, are explicitly designed as fun, durable toys for kids, while detailed static models like the asphalt paver and dump truck also appeal to adult collectors who enjoy engineering and machinery replicas.

Q8: Do the models come pre-assembled, or do I need to build them?
A: The vast majority of our construction vehicle models arrive pre-built and ready to use or display right out of the box. A few listings are labeled as "model kits," meaning light assembly (such as attaching wheels or accessories) may be required — this will be noted in the product description if applicable.

Q9: Does the RC excavator come with batteries, or do I need to buy them separately?
A: Our RC excavator is sold with the batteries included, as noted in the product listing, so it can be used right after unboxing. Please double check the specific listing for the most current battery and charging details before purchase.

Q10: How do I clean and maintain my construction vehicle model?
A: Wipe down the model with a soft, dry cloth to remove dust and dirt. Avoid water or solvents on static diecast models, as this can damage the paint. For the RC excavator, avoid submerging the electronic components in water even though it has a water spray feature — only the designated spray function should come into contact with water.

Q11: What if my model arrives damaged or with missing parts?
A: Please inspect your order as soon as it arrives. If you notice any damage, missing accessories, or defects (including issues with the RC excavator's remote or batteries), contact us immediately at service@nuotie.com with photos so we can arrange a replacement or refund.

A: We offer a 30-day return policy from the date of delivery. Items must be unused, in their original condition and packaging, with proof of purchase included. Sale/clearance items are not eligible for returns — please contact service@nuotie.com to start a return request.
