Looks nice - should fly well at that weight.  Glad to see you've wisely allowed for plenty of height adjustment in the tank mounting lugs - I bet it'll need to go up about an eighth of an inch to stop it running rich when inverted.  Look forward to hearing how she goes!
You want to make 'em nice, else you get mad lookin' at 'em!

Successful maiden today, 5 flights in all :)

wonderful weather, little wind, 25c temp with lots of sunshine

First flight showed that the model was very nose heavy and slow to respond to elevator.. flew a nice and steady level flight
Removed the muffler! yup I was naughty but it improved the elevator response

Second flight I was able to fly inverted and showed the wings not level, high in normal flight, low inverted.
Tweaked the flaps slightly as well as taping a heavy coin the the outside wing.
Motor ran nicely inverted so no need to move the fuel tank, this was a nice surprise.

Third flight improved the wings level between inverted and upright.. getting happier!
But the elevator response was still slow, on landing I placed a lump of plasticine under the tailplane.

Forth flight was better, more responsive but I will need to move the CG further back

Fifth flight I moved the lead out guide slight more to the rear, better line tension...  happier now!

So I still have some tweaks and trimming to do, need to buy a fp15 tongue muffler :)

All up, not a bad model...  yup I am a happy little control line flier
