FAQ

How are the difficulty levels determined?

Difficulty is based on factors such as piece count, assembly time, component size and the precision required during construction. Always check the individual product page because models within the same level can still vary.

Which difficulty level should I choose for my first build?

Beginner kits are the best starting point for most first-time builders. Choose a design with a shorter estimated build time and fewer intricate steps, especially if you have limited model-building experience.

Can a beginner build an intermediate model?

It may be possible if you are patient and comfortable following detailed instructions. However, a beginner model usually provides a smoother introduction to the assembly process.

How long does it take to build a model?

Build times vary by design and experience level. Beginner models may take around one to two hours, while more complex projects can take several hours or longer. Each product page provides an estimated build time.

Are tools included with the model kit?

Box contents vary by product. Review the “What’s Included” and “Requirements” sections on the product page to see which tools are supplied and whether anything else is needed.

What if my order arrives damaged?

Contact us within 7 days of delivery with your order number and a photo. We'll arrange a replacement or refund, no return shipping required.

What should I do if I get stuck during assembly?

Check the product guide or available assembly resources first. If you still need help, contact Mostarle Support with your product name and details about the step you are working on.

What happens if a component is missing or damaged?

Submit a replacement-parts request with your order number, product name and the relevant part details. Our support team will review your request and advise you on the next step.
