Ok guys this is my first HPR build it is going to be my L1 and L2 rocket.
The L1 cert flight is going to be on a loki H-100-sf spitfire with a H-144-lw as a back up motor in case it doesn't qual for some reason. The L2 is going to be on a J-528-LW. Obviously I am not going to build this stock I am going to glass the tube and use 2 30" chutes for recovery and I will be adding an alt bay. The first probable I ran into is that the payload section is to small I could just order a larger one but I have decided to glue the payload sec to the body tube and then fiberglass, after that I will cut the tube farther down for the ebay. the first thing I am going to do is build the alt bay due to its small size I am going to let the ejection charges float if you have a better idea I would like to hear it. The alt bay will be connected to the payload bay with plastic rivets and it will pop the NC off for deployment of the chute using the charge to help the 2 cutes out of the tube.
well now that we have gotten my plans posted lets get to my first question. this kit has tube couplers to strengthen the body tube. The couplers are supposed to be put in after the MMT and fins have been attached. I cant do this before I glass the tube but I need to use a coupler to glue the payload bay to the body tube. So how should I go with this should I build the mmt dry fit it then install the couplers and remove the MMT and fiberglass with balloons or something installed in the end to add strength for when I use the shrink wrap tape with the fiberglass. or should I just use balloons or something in the ends fiberglass then install the couplers after I cut the tube for the alt bay? kinda at a loss as to how to go about it. I will post pics later I am on my laptop right now
