Description

This is a modified controller board that replaced the original controller board that hold the original speaker and tank controller from Haya. The revised controller board is totally flat at 3mm thickness to potentially stiffen the classis and at the same time has a flat surface to install tank electronics via double sided tape. There are mounting holes that hex nuts can be inserted to mount TK50 controller board and 10W viston speaker from rctank.de. The modified TK50 mount board with the correct screw holes are available at https://cults3d.com/en/3d-model/game/clark-tk50-base-mount-board-ongbenghui Existing screws or M3 countersunk screws can be used to mount the board to the chassis. The speaker mount is designed to use M3 screw and nuts. TK50 mount is designed to use M2.5 flat screw and nuts. Cover the screw holes with tape to prevent any potential shorting of the board electronics.
