Well - Here goes.
I have been back in to rocketry for about 9 months now, and have 90% of the parts for my L1 rocket on hand. I have decided to log the construction and certification flight on TRF.
Not only is this my level 1 rocket, it is also my first scratch built rocket. I decided to go scratch built with all of my cert flights, based on the fact that I think that I will learn more, compared to using a kit.
As an overview this is going to be a simple 4FNC rocket. The airframe is 4" PML phenolic tubing, 4" PML nose cone and .250" aircraft birch ply fins (not ordered or stock). overall lenght is 53.25" and an approximate weight of 61 oz (3.8 ponds).
I have decided on using a piston ejection system and a 66" military chute. the harness between the airframe and piston will be 9/16" TN about 7 feet long. The harness from the piston to the nose cone will also be 9/16" TN and about 15 feet long with the chute mounted at the 2/3 mark (5' from the nose cone.
The paint scheme is all silver with black lettering and graphics, and is a tribute to someone which i will disclose after they are informed (keeping it a suprise).
I will be posting pictures as the construction and finishing progresses, and look forward to everyone's feedback. the first pics should be posted with in 2 weeks.
