Estes Black Brant XII Vander-Burn Plywood Upgrade Kit - #9723

Upgrade your Estes Black Brant XII to the max with our high quality, durable laser-cut plywood components! Let your rocket take on bigger impulse engines, as the plywood components can handle much more strenuous forces than the stock balsa and cardboard components can.

Vander-Burn model rocketry components are made for experienced modelers who are comfortable modifying their own rockets beyond supplied instructions. As with any modifications from the original manufacturers’ design, you may need to add nose weight to re-balance the rocket, and any potential modifications should be completed in a simulation software or properly tested before building and launching.

Included Components and notes:

Four (4) 1/8" thick Baltic Birch Plywood tabbed lower fin cores (apply the kit’s balsa skins over the cores and sand as directed) - please note this is only for the larger lower fins. The other fins in the kit should be fine without an upgrade.

Three (3) 29mm to BT-70 Baltic Birch Plywood Centering Rings

One (1) 29mm to BT-60 Baltic Birch Plywood Notched Centering Ring (for Kevlar shock cord)
