[waroff]

Hi,

I stay two weeks in Thailand, I like this this country and people. It is very different, it is sure, I will go another time.



Yes there was these draisn under fuselage, but there was not a long pipe on the fuel drain

Don't know if this would be a clue or not Vic.

Hi,

Fantastic Waroff, just what I needed. Glad you also liked Thailand, did you visit the water markets?

Don't know if this would be a clue or not Vic.

Thanks Bill old chap, that gives me a good guide not only with what I now know is the fuel vent but also with the gun sight which I had an inkling about but was not sure.

Thanks again Bill, just pulled it down and will look at it tomorrow.

Curtiss Hawk 75A-2 Cut-away

this cut-away of "A2" is nice but there are some errors
"49 bevel drive": do not exist
"54, 7,5mm Browning", their lenght is too long, they was ahead the main spar, they were no through the spar.
"61", the ammunition boxes were ahead main spar, on each side the guns
and their access were by lower surface of wing not as on the drawing.
"9", there were 5 cowling flaps on each side, not 6.
"14 forward fuel tank"..at this place there were the ammunition boxes and shells, links chute.

 

[Vic Balshaw]

That is interesting about the Bowning and ammunition boxes ahead of the main spar, the Browning barrels would have been quite short and one would have thought the undercarriage leg housing would have got in the way when you have double Browning fitted on each wing.

Good work on the corrections Vic. It seems strange that the guns and ammo boxes would be further forward.
Although I don't doubt the comment, presuming there is some evidence, that would put the front of the receiver right up against the inside of the wing leading edge, with virtually all of the barrel exposed, and the fit of the ammo magazines and belt feed tracks would be very tight indeed.

I'm wrong when i wrote "main spar" for the web ahead the wheel bay.

I'm sure you'll make this one shine Vic.

Thanks for looking in guys and thanks also Waroff for the confirmation on the gun positioning. I have another question for you, if you wouldn't mind.

It concerns the radio aerial wire from the tail fin to its entry into the airframe. The picture below shows what the artists interpretation of the wiring should look like, tail fin to each wingtip and the wire to fuselage, but from the photographs I have been able to find from the WWI era, none seem to have this configuration and the closest I can get is a wire from the tail fin to just behind the cockpit (see red line and blue arrow). Can you throw any light on this.

Progress is coming on and I'm hoping to be reapplying the decals at some stage tomorrow.

Vic, simply lovely work. Seems as if you are getting it all sorted out. The paint job is a work of art.

And, yes, she did run off with the pastor who never left his wife. Some how that is my fault. oh well.

Vic,

The layout of the antenna wire depended on the kind of a radio-set. The one that can be seen in the profile is more charakteristyc for early Hawk75 (P-36) without the antenna mast. These French Hawks had the antenna mast what indictes the antenna wire run like you showed in the profile with the red line. However I have found that the entry point to the radio-set in the fuselage could have been just behind the mast at the top of the fuselage but not on the side.

 

[waroff]

insulating terminal on the top fuselage, slightly right side, juste behind the rear window

On this pic, we can see the mast antenna and the wires which go from tail to each wing tip,
(the lenght of wire of this dipole antenna vary with the type of radio, so the position of insulator could be different)
the wire going from insulating terminal fuselage to the dipole antenna on the tail is not visible

Ties on the tail and wingtip

And now all is clear.

Your a wealth of Hawk 75 information Waroff.

[Vic Balshaw]

Many thanks you good and trusting friends, so I go with the wing tip-tail fin-wing tip antenna with a connection to the fuselage starboard positioned insulator from the starboard wire as per the original profile. This is good as I'd already drilled the holes to accommodate it.

 

[Lucky13]

Excellent work and info lads!

 

[Wayne Little]

Yep sure is...

 

[Airframes]

I agree, good work all round.
