Dont know if this is of any use for team daidalos,


------------------------------------------------------------------------
Bf 109G (Gustav)

Modelling comments: The 'G incorporated the following changes from the 'F:
* Larger tailwheel (non-retractable, tailwheel well
faired over)
* Larger main wheels with different tread pattern, with
bulged fairing in wing top to accomodate larger main wheels
(G3 onwards except G4)
* Slightly larger supercharger intake scoop.
* Later 'Gs incorporated cowl bulges.
* Canopy side windows have vertical brace in middle of
panel, and the elimination of the lower quarter-lights
(i.e., the small triangular windows below the windscreen).
This is in aid of cabin pressurization.
* Pilot's head armour is bulkier, and more "wrap-around".
This is in aid of cabin pressurization.
* Addition of a pair of small scoops behind propellor hub
on both sides of fuselage for engine direct cooling.
* Late 'G-5 was the first to incorporate "Galland"
canopy, which wasn't standard until the G-14.
* Upper cowling is recontoured to provide a virtually
unbroken curve from spinner to fwd. decking.
* Upper cowling on 'G5 and later incorporated bulges for
the breech of the Mg 131 machine guns.
* Enlarged oil cooler

The following tables list the various field and factory modifications
applied to the Gustav. Specific type entries incorporating these
modifications have been simplified to save space--consult the base

Bf 109G-1/Trop
Tropicalized G-1 suffered from jamming of the MG 151/20 cannon. To
compensate for the loss of firepower, the MG 17 machine guns were replaced
with MG 131 machine guns c/w the resulting cowl bumps needed to provide
clearance for the breech & ammunition path. The dust filter is of Italian
design. This configuration saw service in the Med., North Africa & South
Russia.

Bf 109G-3 (Introduced Aug '42)
This variant was the first 'G to introduce the wing bulges for the larger

Bf 109G-4/R7
(G-4 with D/F equipment)

Bf 109G-5
The Bf 109G-5 was the first of the Gustavs (excluding the /Trop?) to
introduce the distinctive bulges on the cowling, which were required to
accomodate the breech and ammuntion feed chutes of the MG 131 machine
guns. Those a/c equipped with the DB 605AS have "AS" appended to the type
designation (e.g., Bf 109G-5/R3AS). GM 1 nitrous oxid injection gave way
to dual-stage supercharging.
