When i was around 11-12 i built low power rockets with BP fuel, but now that i'm old enough to mail order my own composite, i've begun to think about mid power and high power rockets. I bought an estes monarch and modified it to hold E composite motors, but now i'm creating a semi scratch built minimum diameter rocket.
18" 24mm tube
24mm ogive 3" nosecone
10'' plastic parachute
Avion Balsa Fin set from apogee rockets
3/16" LL @2.5" long
standard size A-D BP motor hook (to be attached to outside...any tips?)
18mm-24mm adapter ring from monarch rocket for forward engine block (works great since it allows room for the forward closure on an E composite motor)
5' kevlar shock cord (length for looks only, should be moving near 0 f/s at parachute deployment )
Before i begin, i have two questions...
1) what's the best way to mount an engine hook on the outside of a rocket without using one of those thing clear plastic rings?
2) On a 3 fin layout, how do you guys get the places right for gluing on a scratch built rocket if you don't have the little cut out thing?
