Narrative:
After takeoff from virginia tech - bcb (2100 ft MSL), I contacted roanoke departure on 126.9 at approximately 3000 ft. They assigned, and I complied with an assigned squawk. I then attempted to obtain an IFR clearance to 54A while continuing to climb in VFR conditions. The controller confirmed radar contact at 4000 ft, but refused to get/give me a clearance into IFR conditions until, as directed, 'I could maintain 5000 ft in VFR conditions.' the ceiling was very ragged and I found a small hole in which I could climb to 5000 ft. Visibility was poor, 3/5 mi. In order to maintain cloud clearance, I was at times having to make steep turns. As I was copying the clearance in a steep turn, my altitude got up to 5400 ft, to which the controller 'threatened violation' -- even before I read the clearance back. I then turned in the direction of my first fix. Shortly afterward, the controller requested my heading, to which I replied. After another couple of mins the controller advised that radar had me 10 mi north of course, turn left and climb immediately to 7000 ft and to maintain terrain clearance. I complied. I found that my directional gyroscope was about 40 degrees off compass heading. I presume this was caused by the steep turn maneuvering while attempting to climb to 5000 ft. I am 'reasonable' confident I set runway heading on the directional gyroscope at takeoff. The rest of the flight was uneventful. Lessons I learned were: 1) do not let myself get trapped with a clearance that requires steep turns to remain VFR. I believe the controller could have issued me a clearance at 4000 ft -- fully within VFR clrncs. 2) rechk, rechk, rechk the accuracy of the directional gyroscope with other instruments on board.

Title: SMA PLT DEPARTS VFR, HAS DIFFICULTY OBTAINING IFR CLRNC. WHEN ACCOMPLISHED, HE HAS HDG DEV, ALTDEV.
Narrative: AFTER TKOF FROM VIRGINIA TECH - BCB (2100 FT MSL), I CONTACTED ROANOKE DEP ON 126.9 AT APPROX 3000 FT. THEY ASSIGNED, AND I COMPLIED WITH AN ASSIGNED SQUAWK. I THEN ATTEMPTED TO OBTAIN AN IFR CLRNC TO 54A WHILE CONTINUING TO CLB IN VFR CONDITIONS. THE CTLR CONFIRMED RADAR CONTACT AT 4000 FT, BUT REFUSED TO GET/GIVE ME A CLRNC INTO IFR CONDITIONS UNTIL, AS DIRECTED, 'I COULD MAINTAIN 5000 FT IN VFR CONDITIONS.' THE CEILING WAS VERY RAGGED AND I FOUND A SMALL HOLE IN WHICH I COULD CLB TO 5000 FT. VISIBILITY WAS POOR, 3/5 MI. IN ORDER TO MAINTAIN CLOUD CLRNC, I WAS AT TIMES HAVING TO MAKE STEEP TURNS. AS I WAS COPYING THE CLRNC IN A STEEP TURN, MY ALT GOT UP TO 5400 FT, TO WHICH THE CTLR 'THREATENED VIOLATION' -- EVEN BEFORE I READ THE CLRNC BACK. I THEN TURNED IN THE DIRECTION OF MY FIRST FIX. SHORTLY AFTERWARD, THE CTLR REQUESTED MY HDG, TO WHICH I REPLIED. AFTER ANOTHER COUPLE OF MINS THE CTLR ADVISED THAT RADAR HAD ME 10 MI N OF COURSE, TURN L AND CLB IMMEDIATELY TO 7000 FT AND TO MAINTAIN TERRAIN CLRNC. I COMPLIED. I FOUND THAT MY DIRECTIONAL GYROSCOPE WAS ABOUT 40 DEGS OFF COMPASS HDG. I PRESUME THIS WAS CAUSED BY THE STEEP TURN MANEUVERING WHILE ATTEMPTING TO CLB TO 5000 FT. I AM 'REASONABLE' CONFIDENT I SET RWY HDG ON THE DIRECTIONAL GYROSCOPE AT TKOF. THE REST OF THE FLT WAS UNEVENTFUL. LESSONS I LEARNED WERE: 1) DO NOT LET MYSELF GET TRAPPED WITH A CLRNC THAT REQUIRES STEEP TURNS TO REMAIN VFR. I BELIEVE THE CTLR COULD HAVE ISSUED ME A CLRNC AT 4000 FT -- FULLY WITHIN VFR CLRNCS. 2) RECHK, RECHK, RECHK THE ACCURACY OF THE DIRECTIONAL GYROSCOPE WITH OTHER INSTS ON BOARD.
