Estes So Long Vander-Burn Plywood Upgrade Kit - #9722

Upgrade your Estes So Long 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:

Six (6) 1/8" thick Baltic Birch Plywood surface-mount fins (3 for the booster and 3 for the sustainer) to fit Estes So Long kit #9722.
