Rocket Glider from Thermic 20
Did anyone else build a rocket glider from the Thermic 20 ?

Yes but I think it was about 1970! Boost gliders are best with slightly less wing span or area or with lower thrust motors. However Estes motors of the time had a high thrust initial slug. The closest motor was the B4, but that had one too.
That said, stick one on the side of a Saturn V which flies slow anyway and you have something (weird). Jerry |

I've built a bunch of these. I used polyhedral wings, not dihedral, and you obviously have to put the rudder on the bottom to clear the exhaust. Otherwise, they were stock. They fly fine on a B4-2.
If you got with a C6-3, they'll need strengthening with a more robust boom (spruce), denser balsa and tissue or silkspan covering.

Yeah, it was around '71 or '72 when I built one as a dihedral. On a B motor it stayed aloft for a couple of minutes.
