BRS has packages for Experimental Aircfraft
http://www.brsaerospace.com/experimental_aircraft.html

Because this plane is being built to attempt a climb record, rather than a speed record
the maneuvering speeds it will encounter will not be very high
thus the airframe will not be subject to high G forces

The only danger I foresee is flutter or vibration failure, which could destroy a plane in seconds

If catastrophe occurs - is the plane worth saving at a cost of a 35lb BRS?
or should the pilot just bale out and land using his personal parachute?

Incidentally, while deployment of a BRS parachute totals the plane,
most insurance companies would rather pay the total loss,
rather than pay for personal injuries/death

Flutter is unlikely as the climb speed is well below the VNE of an RV4.
The vibration due to the rotary is near zero.

We would take the chute off after the testing and before the attempt.
