We had one rocket and slid the fin sections over the motor mount then used blue painters tape to make sure they didn’t come off
Ready for the science fair [ATTACH]
I did not do that .. just built then flew
The rocket weighed 4pounds 3oz and they all flew fairly straight
I have the pattern for the fin if someone wants to try....all the fins had an area of 4.09 square inches
Yes we launched on the same day same angle same weather conditions
Thank you was all my sons idea I just helped... made me a BAR again
The number for each launch could vary 20 feet but the speed was always fairly consistent
We left the edges square so the edges were the same and eliminate the variable of differences in the edge if we rounded them and there were not...
Took the average of 3 flights
Number 10 was the highest 409 feet and Number 4 was the fastest at 106 mph
An upgrade went through 4 9 volt batteries this weekend... 30 flights but it was only in the 40s outside... looking for something that would last...
Does anyone have a solution to replace the 9v battery to go in my Estes astron launch controller
I’ll post the rest of data later that’s all I could remember
#10 went the highest 424 feet fastest went 108mph pulled 9.8 gs at lift off used a Estes C 6-5
Was doing 3 fights with each the vent holes were already in the payload bay
Ready for flight tomorrow at least 30 flights to see if the fin shape will effect speed and altitude [ATTACH]
Ready for flights tomorrow [ATTACH]
We are using a jolly logic altimeter two for speed and altitude and multiple flights
