The first rocket was very beautiful in its simplicity. I thought it performed perfectly. Much respect!

Thanks piroart for the D1 comp. I did notice after I asked that you mentioned it already. It's one of the many star comps Ive yet to make. I have made winokur 20 with large flake alum. Not as good as alcoa 120. Needs to get some from hobby chemical supply. Have you tried wino 19? That one uses granular magnal 100-200 mesh and it really flashes big and bright but not as dense.

Yes, i used winokur 20/19, each was magnalium(not granulated, 160-200 mesh).

Winokur 20 long tail, long delay between flashes.

Winokur 19 short tail, short delay between flashes(flash more often).

Very beautiful heading! Congratulations.

[swapnilsutar1988]

Appreciate..!
Well done...

[gtvpo]

Wow... Those are some seriously impressive rockets. And the headers are incredible!

 

Just out of curiosity, do you have the weights of the actual headers and the weight of the BP used in the lift motor? I'd like to do some dead reckoning on the excess energy of the motor.
