Ive been juggling the idea around in my head for alittle, and i guess ill start on it...
Im thinking of a 2 29mm mount cluster... I have a body tube which, evidentally, came from the garbage... Its about 34 inches long, and 3.5 OD, so this things just begging to fly...
I did a really quick sim of it, with just some random fin design and nosecone for just some idea, and i got some pretty promising numbers...
Ive made plenty of smaller 24 and 18mm scratch rockets, but for this one im not quite sure about a few things...
1. What should i use for an engine block? WIth all other smaller ones i would just chop up a used estes motor... Is there a BT that fits inside a bt-52 (that is a 29mm mount right?)... How far back should i push the block? (3.75 rings some sort of bell...)
2. For a motor hook or just retainer does anyone have suggestions of what to use?
3. Fins: Ive heard of everything from Plywood to birch to basswood... I dont know what would hold up for a 29mm rocket...
As far as the nosecone, i guess ill ask sandman about it (once i have an idea what im making), and parachute, i have one from an my arreaux that i dont use...
Thanks a bunch
