If you do your L1 with this rocket (which it absolutely can), my only concern is the landing. But as long as the field is soft, it shouldn’t matter, but if the field is hard (like compacted sand/ dirt like down here, or in the desert) but that shouldn’t be a problem, but I’d say don’t round or airfoil the trailing edge to prevent splitting if it’s ply, or to induce more drag so you don’t lose it!
And as long as you do some big ol’ fillets, internal and external, almost anything could handle most small H’s like an H128 (reload), which doesn’t have Hazmat and you could probably even just borrow a case! And a J/L is a good idea, because of shorter recovery, and if it fails the chute is still out causing drag, so it might still be fine.
Shakedowns on G’s and F’s are a great idea. And a orange and black color scheme would be very cool, but I’m a bit biased on that.
Good luck!
