Test pilot crew of a C560XL experimental aircraft were making a high speed taxi to test a new thrust inertia reverser and became airborne when the reversers were deployed. They regained control of the aircraft and continued to climb out from the lift-off.

Narrative:
Conducting engineering test of pitch-up due to thrust reverser deployment. Cleared for high speed taxi. Deployed thrust inertia reversers at test condition, aircraft went airborne. Pilot executed a climb out, no damage, no conflict. During engineering flight testing of experimental aircraft -- be prepared for the unexpected.
