Cleaning up my work bench the other night and the parts pile got me thinking about what I could build with what I had.
I have always wanted to play around with a cluster but didnt have cluster centering rings- so why not pods instead . Here is what I have come up with so far. Its a BT60 full tube then a half one I had-lol. then some balsa papered - thru wall fins as well as the pod mounts.
Thinking of a D-12 /5 or 7 center and a pair of A6/0 for the pods for a first flight. Not really gonna bother with any type of finish until after it gets a flight and proves its self .
Open to constructive comments or concerns. If this isnt the right place for this , feel free to move it.

I hate half the time my pics are right and the other sideways- sigh, sorry.

Do you have any vents in the pods? I think you'll need them so the pod motors don't try to eject themselves (and now as I'm typing this I realize I don't quite know how strong the forward pop is on -0 motors. Obviously there are at least *some* gasses ejected forward...)

I don't think Estes makes A6-0 motors anymore, since they're not very useful as boosters. B6-0's in there would seem reasonable; the D is still gonna burn twice as long.

I like idea of three-inline clusters; should make a nice smoke trail going up. I was thinking of building one and canting the two outer ones, to make the triple-smoke trail even more pronounced. Get some good pics when it flies!

Estes reintroduced A8-0s a few years ago and they are currently available.

Interesting design!

So , with that said , anyone see any obvious design flaws or reasons - IT WONT WORK ?? -
Im fine with an A8/0 as it will only help. Frankly in the end I was thinking a soft F- Center and 2 outboard C-s soo. :wink:

Yeah , initially the plan was to center line vertically all 3 motors- the first standoff for the booster somehow got a little tick upward - so I made the other one match it :facepalm:
Guess there is only one way to find out, :cool:
This thing is built pretty tough, tru wall fins as well as the booster standoff- both sides of the standoff ( motor and rocket) I added a reversed engine hook to the pods to keep any forward motor movement away as I will be gluing the pod nose cones in place. - once again, open to concerns here.
