Well, I've accepted the commission from Earth Day project with Space Center Houston, so I will try to do a build thread and appreciate any advice I can get.
Desire is for rocket(s) built out of textbooks.
My original plan was one small one launched on a D and one larger one on 3 Ds. May need to go with a G for the larger. Want to stay out of high power land.
Got the books covers---- great building material but heavy, especially with the polygonal plan I have in mind.
Here is what I have so far.
The little blocks are cardboard "fillets" that keep the alignment straight.
The "fin can" for the larger rocket is already at 321 grams. This is 11 inches long. Was planning on 3 sections plus nose cone, estimate the other two sections also 11 inches long will probably come in around 250 grams each, nose cone probably 150 grams. Still need to add engine mount, parachute won't weigh that much. Plus engines. 3 Ds at 41 grams each so add another 125 grams, already at nearly 1100 grams. So either need to go up to 4 Ds (cluster reliability starts to become an issue) or go to a bigger engine, thinking a G. Hoping I can FIND a G for a test flight at hobby lobby (seems like they have stopped carrying the composites, but will check again tomorrow)
Thanks all
Tom
