This is the first launch of my BT-80 upscale of the Estes Flutter-By. Power was an Estes D12-5 and the rocket made it to about 200 ft. The delay was a bit too long and separation occurred well after apogee. I will try a D12-3 for the next launch, as well as E power. This rocket will probably be a test mule to experiment with a few ideas and build my vision of the ultimate Flutter-By.
