BRS told me this morning that they started an RV-8 project years ago and gave up. The person could not tell me why.

The generic one? I tried to order the RV08SI-08 listed here and they said that they do not sell it.

The engineering project for the installation of the ballistic parachute was not created by BRS, I'm only using their parachute, the project was designed here in Brazil by an aerospace engineering company, the same company that carried out the ballistic parachute project for the RV-10 that BRS sells.

The BRS ballistic project for the RV-10 was made by a Brazilian company, the same one that carried out the project for me for the RV-8.

Default Good luck with the parachute install!

Thanks for the offer; PM sent

Regarding bridle strap routing (and my plane is a bit different due Fastback), I'll share part of my modification in case you may want to consider something similar depending what chute deployment angles you predict.

I welded a nut on top of my aftermarket roll bar before powder coating and installing it a couple months ago. A bracket that engages with the nested canopy frame will be bolted to it. I expect a full width nested frame will increase my "safe" areas as well as help support the canopy in the event a strap is in a position to exert a side load (thankfully the angles required for that are near perpendicular to the strap ).

There are many on this forum better at engineering so as always, I welcome input!

Do you have more photos? I'd also like to see it finished and know the materials used to calculate if this will work correctly.
I liked your solution.

The links are from the RV10 project tests.

You can look for more on their YouTube channel, write in Portuguese. "paraquedas" on their channel page.

The roll bar is alloy steel that was TIG welded to the WD-808 seatback. As I am very tall, the roll bar was built as high as possible in addition to building the canopy high.

The rest was built from aluminum crops I had on hand. Perhaps with a standard '8 you have better options for mounting vs a moving composite structure like mine? With the tipover canopy and pre-existing components, there was a LOT of 3D geometry to make this all fit nicely so I just kept rebuilding it "in situ" until I got the fit that I was looking for.

The image is a bit distorted to capture the full view in the small space of the back seat. This assembly weighs way less than my GPS but should help mitigate a few more of the "what if" parachute deployment scenarios.

Once I finish avionics/electrical/servos/static line, I will final rivet on the turtledeck and then can return to BRS installation tasks but that will be a while...
