Narrative:

Aircraft is RV8 with 10-360 engine and 2 lightspd electronic ignitions. 2 days previously, aircraft had unacceptable RPM drop on right ignition. Replaced spark plugs and ran engine extensively on ground. Checked ok. Decided to return aircraft to home base -- cxo. On takeoff at approximately 200 ft AGL, I lost power. Engine still running but virtually no thrust. Too late to put it back on runway and too low to turn. Kept aircraft from stalling and continued glide straight ahead. Landed in a cow pasture. No damage to aircraft or property. No injuries.
