Estes Big Daddy 38 mm Vander-Burn Plywood Upgrade Kit

Upgrade your Estes Big Daddy 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 through-the-wall fins to fit Estes Big Daddy kit #2162.

Three (3) 1/8" thick Baltic Birch Plywood 38 mm to 3” centering rings (one ring has shock cord mounting holes)

One (1) Motor Mount Tube 38 mm x minimum 6.5” (you may need to cut down to fit). Centering rings may need to be sanded to fit tube, as we source these tubes from different suppliers.

Requires either motor friction fit, or a 38mm motor retainer (not included but can be purchased here).
