I prefer the other one, found on the same page list. The one where the wing seperates & the BRS does what it's intended for..

BRS for RV9A
 
I have put a BRS in my RV9A and had no problem for installing it. But due to the parachute belt cover interference against the canopy rail, I can't use my canopy locker. Did anybody experienced a similar situation and can share the solution? Thanks!

The parachute does an awesome job until the plane is on the ground. Then, while the pilot is trying to get out, the chute drags the airplane all over the place... And something happens that starts a fire?

Is there no way to "cut away" the BRS once you're on the ground?

If you have installed a BRS in your 9A, I would love to see photos and learn more. Thanks

Rob,

I had a BRS on n Aventura HP. The typical scenario for use was a midair or loss of control which probably would not involve a fire. The situation you describe might be possible, but the chute definitely solves more problems than it might create.

If you do want a cut away system it would probably have to be a mechanical latch at the bridle attachment point because the Kevlar tether is one tough rope! The riser lines are all in the chute pack, so I don't see any practical way to add a cut away there unless BRS designs it in.

Possible Alternative Aircraft Recovery System
 
I believe that Second Chantz may be in the process of developing and qualifying an aircraft recovery system in the RV-12 weight and airspeed class.

They have a lot of experience in this area and use an alternative to the pyrotechnic drogue deployment system used in the BRS installation.

Good guys with a lot of saves in the hang glider, parasail, and ultralight world.

Looks like the Sling design uses a system from Magnum in the Czech Republic and supplied and supported by Bostik Industries, LLC, Melbourne, FL. Uses a pyrotechnic rocket motor to deploy the canopy. Probably pretty good. I am not a fan of pyros in small non-military aircraft unless absolutely necessary.

Might be worth a look if you are considering a airframe recovery system.

Sling???
 
Suggest that if you really have to have a BRS in your RV-12 that you have a serious look at a SLING-2. It is an LSA and a quite capable aircraft - available in both kit and as a SLSA. It is designed for the BRS and comes standard with one I think. It is a quite capable airplane. Check it out.:cool:

Ok, I will send a photo to your e-mail. Regards!

I would think the fuel tank location would be problematic in the RV-12 because you either have the rocket exhaust in close vicinity to the fuel tank (if mounted in the baggage area) or lanyards which could rupture the tank when tensioned (if the BRS is mounted behind the baggage bulkhead and anchored to the spars).

With regard to the arguments about G-forces my feeling is it's better to have an option you may not be able to exercise than to have no option.
