Narrative:

I had just delivered cargo and was departing on a single pilot part 91 flight home. I obtained my IFR clearance through FAA radio which was 'direct' to my destination. I departed the airport using runway 12. The following was the current metar: speci kzzz 281622Z automatic 09026g32kt 1 3/4SM -RA br OVC004 08/07 A2937 rmk AO2 pk wnd 09034/1608 RAB20. As I was climbing through 200 feet AGL I smelled and viewed what I deemed to be electrical smoke in the aircraft. After turning off all non-essential electrical items I communicated my emergency over CTAF to an aircraft waiting to depart behind me; as well as letting them know I would be returning to the field immediately. As I was climbing through approximately 2;500 feet MSL I attempted to contact center while squawking 7700. I am familiar with the airport's local area and knew that radio and radar coverage was poor so I continued the climb in order to establish communications as well as get above the 3;000 feet MSA. At the same time I deviated from my assigned course to vector myself toward the ILS for runway 12. After reaching 3;500 feet MSL (the glideslope intercept altitude for the ILS) I was able to communicate with center. I stated my emergency and requested vectors for the ILS. Center was unable to provide vectors unless I was able to climb further for radar coverage. In the interest of time and safety I declined; informing them I would vector myself at 3;500 feet MSL on to the approach. After flying the approach and landing I taxied to the ramp; as the smoke had dissipated through the short flight. In summary; I deviated from my IFR route and altitude clearances to meet the needs of my emergency. I feel that these deviations were necessary to ensure the safety of my flight by getting the aircraft on the ground as quickly as possible.

Title: A BE-90 developed electrical smoke after takeoff; so the pilot in IMC deviated from his clearance; climbed to the ILS glideslope intercept altitude; communicated with ATC and landed at the departure airport.
