I finished this one a couple of days ago.
It's a very easy model to put together...big locating pins and almost snap fit like Neil mentions. I even managed to get the leading edge gun inserts fitted without filler...i just used LOTS of solvent and simply pushed then in hard until the soft platic oozed out. When they set, just sand- no filler.
I swapped the canopy with a spare Hasegawa item, i think if Airfix only ever address one thing with this kit then it should be the clear parts.
I also shortened the gear legs by removing the section between the the two middle "collars", the gear then seems to sit at about the correct spacing.
I also swapped the wheels with a pair set of HobbyCraft wheels that i had (believe it or not the HobbyCraft/Accademy Bf109 wheels are the best in 48 scale!).
I left the prop alone and i don't think that in the end it is all that noticeable.
The only extra thing that i noticed, and that i'll address in the next build is the upper fuselage profile aft of the cockpit. I think the upper corners on the spine are too sharp with a flat spot on top- very similar to ICM's 1/48 Bf109F series. It should be more egg shaped i believe. If anyone agrees then the good thing is that it's a very easy fix, just over engrave the effected panel lines and sand down the corners of the spine. The plastic is very thick, so i see no problems in getting the more rounded shape.
I think overall though it's a good effort by Airfix and i will probably buy more at the cheap price they sell for. I still like the Hasegawa kits better though, especially the cheap Revell boxing.
Gunze paints. Revell decals from their Hasegawa boxing, i believe it was an early Marseille aircraft.
