Hey, thats my rocket review. I did fly it as a cluster but do not remember much about it anymore, it was a while ago.
When I saw the kit, it screamed to me- "HEY! Put motors in these pods and FLY ME" So, I did.
I believe that I put in 2 A10-0 in it when I clustered it. I am pretty sure that the 13mm motors were a perfect fit into the tubes
It is now in the corner of the room with a lot of other rockets waiting for repairs. The balsa for the pods is not strong enough and broke. If you build one beef up the supports by useing basswood or a thin ply and it should last longer then mine.
