Scratch & Dent Estes Der Big Red Max Vander-Burn Plywood Upgrade Kit
** SCRATCH & DENT VERSION, MEANING THE PLYWOOD HAS SOME DAMAGE THAT WE CANNOT SELL IT AS A “GOOD CONDITION” ITEM. SOLD AT A DISCOUNT, AS IS, NO REFUNDS. PHOTO DOES NOT SHOW DAMAGE. READ CONDITION BELOW BEFORE PURCHASING **
Upgrade your Estes Der Big Red Max 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:
Three (3) 1/8" thick Baltic Birch Plywood through-the-wall fins to fit Estes Der Big Red Max kit #9721.
Three (3) 1/8" thick Baltic Birch Plywood 29 mm to 3” centering rings (one ring has shock cord mounting holes, one has fin slots)
Condition: Ply fins may have knot holes, edge gaps, gouges or other imperfections. Fin may be warped. Should be no more than one warped fin per set. THESE WILL REQUIRE SOME WORK to get nice for your rocket. If you don’t want to put in the work, don’t buy them. Centering rings may have some blemishes but most are taken from “good” stock.
