APP
Where Can I Download The iM.Master Apps?
Use the app or download source specified for your product. Compatibility and available functions vary by model and mobile device. If you are unsure which app matches your set, email hello@immastertech.com with the model number and a photo of the box.
Why Can’t I Find My Model In An App?
Confirm that you installed the app named on the product box, instruction manual or product page. Check the model number and update the app. If it still does not appear, send the model number, device type and app screenshot to support.
My Phone Cannot Connect To The Model. What Should I Check?
Charge the power module, turn on Bluetooth, allow the app’s requested permission, close other controller apps, and restart both the model and app. Keep the phone near the model during pairing.
Can One Remote Control Operate Several Models?
Control systems are model-specific. Use the controller and power components supplied or specified for that set. A controller is not automatically interchangeable with every model.
Orders
Where Do You Ship?
Supported destinations, delivery methods, estimates and final shipping costs are shown at checkout for the exact delivery address. Some products containing batteries or electronic modules may have destination-specific restrictions.
How Can I Estimate Delivery Time?
Review the estimate at checkout and the Shipping Policy. Delivery time includes order processing plus carrier transit. Customs, holidays, severe weather and remote-area delivery may affect the final date.
How Do I Track My Order?
Use the Track My Order page with the tracking details from your shipment email. A newly issued tracking number may need time to show its first scan.
Can I Change Or Cancel An Order?
Contact us as soon as possible with the order number. Changes or cancellation cannot be guaranteed after processing or shipment has begun.
Are Taxes And Import Fees Included?
The amount collected at checkout is shown before payment. Import duties, taxes or handling fees not collected at checkout may be charged by the destination country or carrier.
Why Is A Country Or Shipping Method Unavailable?
Availability depends on carrier coverage, parcel limits, local rules and product contents. Try the complete delivery address at checkout or contact support with the product link and destination.
Products & Building
How Do I Choose A Product By Skill Level?
Check the recommended age, piece count, finished dimensions, estimated complexity and control features on the product page.
Are Batteries Included?
Battery requirements vary by model and destination. A battery is included only when the product page or package states this explicitly.
Where Can I Find The Model Number?
Look on the front or side of the product box and on the instruction-manual cover.
What If A Step Feels Unusually Tight Or Will Not Move?
Stop forcing the mechanism. Compare the build to previous steps, confirm pin and axle orientation, and check that gears rotate freely before continuing.
How Do I Request A Manual?
Email hello@immastertech.com with the model number and whether you need digital-manual assistance or help with a printed manual.
Bricks, Parts & Returns
What Should I Do If A Piece Is Missing, Damaged Or Incorrect?
Use our Missing Brick Replacement page. Provide the order number, model number, instruction page and step, marked part callout, quantity, clear photos and current shipping address.
What If An Entire Numbered Bag Is Missing?
Arrange all remaining bags in number order with every label visible. Take one clear overview photo that also shows the product box or manual.
How Do I Report A Motor, Battery, Controller Or Electronic Fault?
Identify the model and affected component, photograph the relevant instruction step, and attach a short video demonstrating the fault.
Can I Request Support For A Set Purchased Elsewhere?
Contact the original retailer or marketplace first because they hold the order record. iM.Master may still help identify the product or correct support route.
Can I Return An Opened Set?
Eligibility depends on product condition, timing and the current Refund Policy. Contact support before returning anything.
What Information Should I Avoid Sending?
Never send account passwords, full payment-card details or unrelated identity documents.
