Yeah but 4oz or 6oz cloth?
I used two wraps of 5.7 oz over PML phenolic years ago and it worked very well.

The Gardian has a split fin design which typically whistles. I presume the whistle is caused by increased turbulence. Which I also presume causes increased force and flutter at high speeds like in the transonic zone.
Can anyone lay down the physics of split fins, whistling and fin flutter?
At the wing tips there are vortices. I’m not certain if that is the only factor. However the vortices are turbulent spirals that cone outward from the tip. I imagine the vortices contact the aft trailing fin set. The aft fin set tips also produce vortices. The elongation of the whistle is due to the Doppler effect of the object moving away from you. As to what theoretically causes the whistle in the first place I am theoretically lost as you guys are as a mechanical engineer student but I would blame the boundary layer flow separation happening at the surface of the fin from laminar to turbulent flow and subsequent interferences on the aft fin set. I have heard whistles on transonic jets landing not the engine noises such as fighter jets. It’s a unique sound effect. I’m not certain what exactly causes it and I know how to mess with math across shockwaves. That still doesn’t explain the whistle. But I tried. Maybe Winston or some Aero nerd knows.

Shame on you... It's a gray SWAT!Nice! I love that black crossbow!!!
The red one isn't an upscale. It's an earlier version of my Starleopard. The orange one with black windshield is a 4.15X Explorer AquariusWhat model is that red one upscale of?

Sorry Jim, the Explorer Aquarius looks red in that pic...at least to me, its cool no matter what color it appears ( referring to the picture of the EAon the stands).The red one isn't an upscale.

I built an avbay into the transition of my Estes Argent, you might take a look at this build thread:

Like this maybe?
There is not enough room in the upper body tube for a parachute and bridal unless I cut the nose cone base.
