Congratualtions!!! (On both counts, but especially flying with your daughter! )
Congratulations on L1Took my LVL 1 and understood the power of well compressed BP charge xD but most importantly I flew rockets with my daughter!View attachment 532419View attachment 532418View attachment 532420View attachment 532421
Congratulations.Took my LVL 1
It looks like the booster plus just enough tube to connect the coupler to the nose cone shoulder. One could buy the coupler kit, then glue a nose cone to a bit of tube and have a twofer (without paying you for the extra kit). But then if wouldn't be a cluster.Also played with an idea for a BT-55 dual 13 mm mini motor cluster stumpy one using the same fins as the Yalga booster. Sims to just over 400 feet. That blank bit of BT is a greeble band, like the Yalga.

Finished off the shaft clamp I printed. Added M4 Helicoil inserts into the threaded holes for extra strength. This will clamp onto the 19mm shaft of my Automatic Antenna Tracker and move some equipment as the shaft rotates. I need to print more for the different receivers, and also variants for the whip antennas, Yagis, patch antenna and the AAT electronics itself.

I also have a battery housing and another bearing support to print. Some other things too. Will be busy on the CAD and printer this week. I hope they don't have too many work jobs to do on it .
Now I need to order more Helicoil inserts...

It's cot me thinking though; I have a couple of little boosters around from lost sustainers. Hmm.
They are some other brand other than Helicoil, but you get the idea. I have used them successfully for about seven years, where needed in ABS prints. This is the first time I have tried them in PLA. These are not the final prints anyway, as those will be in ABS.Out of curiosity: Are those actual "Helicoil" type inserts or do you use the term in a more generalized way? If yes, how are your experiences with them in FDM 3d prints and have you compared them to inserts for thermoplastics?

I use Lexan for clear fins. It is not very expensive. I get it at Home Depot.just glued one of the booster nose cones back together on the Delta II, the super old rocket I got free. I might just toss it as much work as it's going to take. I kinda wanna fix it since I use to work for McDonnell Douglas, there's no fins and the guy said that I would need to make some clear ones.
