Our Price: $6.00

Motor mount kit for mounting seven standard-size 18mm motors in a BT-70 body tube. There are no centering rings or engine hooks included with this kit.

Seven 18mm (BT-20) motor tubes do not actually fit inside a BT-70 body tube. This motor mount kit includes six BT-20 couplers which you glue inside the front of the outside six motor tubes. The couplers form a circle that fits into a BT-70. So, the entire assembly glues to the end of the BT-70 body tube rather than inside it.
