FREQUENTLY ASKED QUESTIONS
Everything you need to know about the MK42 Iron Man Arm.
Yes! We ship to the US, Canada, Australia, and New Zealand with fast, reliable delivery.
You get the full MK42 arm (1:1 scale), a 5-button wireless remote control, and an instruction manual. Batteries are not included - the arm takes 4x AAA (1.5V) and the remote takes 1x AAA (1.5V).
Say "Jarvis" to wake the system - you'll hear a confirmation sound. Then within 10 seconds, give a command like "Open the armor", "Close the armor", "Open the laser cannon", or "Turn off the laser cannon". It supports both English and Chinese voice commands.
The arm runs on 4x AAA batteries (1.5V) and the wireless remote uses 1x AAA battery (1.5V). Batteries can be easily swapped when they run out. Do not use power sources higher than 6 volts.
Yes - it's a real laser pointer built into the arm. You can activate it by voice command ("Open the laser cannon") or with Button B on the wireless remote. It's a low-power pointer, not a cutting laser, so it's safe for normal use.
Press the palm button once to toggle the flashlight. Hold it for 3 seconds to trigger the full repulsor blast - a bright burst of light combined with explosion sound effects. You can also trigger it with Button D on the remote.
Absolutely. You have three control methods: voice (say "Jarvis"), the 5-button wireless remote (armor, laser, palm light, cannon blast, sound effects), and the touch-sensitive palm button for the repulsor.
