This was my second rocket build. After doing my first "Photon Probe" I discovered that I wasn't happy with the wood grain on the balsa fins. This model was done to hone my skills on filling the balsa and getting a smooth finish as well as really nice/smooth fin fillets (where the fins meet the body). Also working on my airbrushing skills. This was a Level 2 build. In the process of working on Level 3 build (Estes Lynx) to further hone skills before tackling the larger Mercury Redstone rocket and then on to 50th Anniversary Saturn V. Here is my first use of CWF to fill the balsa and sanded. Primed. Sanded. Noticed spots that needed more filling as well as the tube spirals.
