Thank you for viewing my listing. Like new! This is a pair of 2.4GHz circuit board and transmitter for a Heng Long 1/16 Ver-7.0 RC tank. Are you having trouble with a broken transmitter or circuit board? This is a like-new pair of Ver-7.0 circuit board and transmitter, used only for function checks. Before listing, I confirmed the rotation of the left and right motors, forward, backward, left, and right, as well as pivot turns and super pivot turns. I also checked the two types of sound switching (Abrams & Leopard sounds), driving sound & machine gun sound & turret rotation sound (the turret rotation unit used is a 5.3 Ver unit (with gear noise)) & gun elevation sound (gear noise is present as it is a much older unit) & main gun firing sound were all working fine. I also confirmed the 4-step volume control. I confirmed the vehicle recoil with the motor's response along with the main gun firing sound. I also confirmed the smoke unit was working well. Here is a video from before the listing. It's on YouTube, please take a look if you like. 　　　　　↓ https://youtube.com/shorts/s-kkhG7Hrgo?si=zyy5MqyfPKhfXdCa The photos and video show the smoke unit, speakers, motors, battery, turret rotation unit & gun elevation unit, main switch, and BB bullet firing unit, but they are not included. This listing is only for the transmitter and circuit board. I hope this will be helpful for those who have problems with their circuit board & transmitter, or for those who are planning to change the circuit board from Ver-6.0 or the previous 2.4GHz transmitter. The Ver-6.0 version has a larger connection terminal for the infrared battle sensor, so you will need to replace it with the size of this Ver-7.0 terminal. There is no problem if you do not use infrared battle. Thank you for viewing the photos. Free shipping via Yu-Pack from Yu-Yu Mercari.
