I need some help with my design of my level 1 certification rocket.
Tripoli rules apply at our local club and their ceiling is only 750 feet, with waiver a little bit higher. Apparently I can attempt my level one but need to stay below 750'.
I have been building for a year now and prefer to build from scratch with little or no factory produced parts. My most recent flight was a 2.8 lb 55 inch on a G125. 798 feet and chute failed to inflate. I know I need to work on my deployment and recovery before I attempt my lvl 1. But I digress.
I understand you can't keep adding weight to the rocket or there won't be enough thrust to get it off the ground. 5:1 minimum, usually 10:1 or greater for my flights. A longer rail or rod helps with getting up to speed I understand as well but there are rational limits to both of these.
Frontal drag was the direction I was pointed. Do I put some canards on it horizontally?
How can I design a rocket with sufficient enough drag to keep an H135 below 750 feet?

Far from professional but professionally fun.
Thank you for any assistance in advance.
