OK, guys, here is a 'quick-fix' for the Bombay, rather than a new set of FDEs.

In the aircraft.cfg file, modify the following lines:
--------------------------------------
[WEIGHT_AND_BALANCE]
empty_weight_CG_position = 1.000, 0.000, 0.000 // was 0.000, 0.000, 0.000
--------------------------------------
empty_weight_pitch_MOI =600000.00000 // was 148843.00000
empty_weight_roll_MOI =400000.00000 // was 89229.00000
empty_weight_yaw_MOI =700000.00000 // was 185419.00000
--------------------------------------
[contact_points]
max_number_of_points=7 // was 0
--------------------------------------
point.0=1.000000,-31.75,0.000000,-3.35,1400.0,0.000000,0.718821,55.740000,0.374504,2.500000,0.661983,5.000000,5.000000,0.000000,0.000000,0.000000
point.1=1.000000,9.58,-9.42,-9.90,2000.0,1.000000,1.618821,0.000000,0.930345,2.500000,0.425010,0.000000,0.000000,2.000000,0.000000,0.000000
point.2=1.000000,9.58,9.42,-9.90,2000.0,2.000000,1.618821,0.000000,0.930345,2.500000,0.425010,0.000000,0.000000,3.000000,0.000000,0.000000
---------------------------------------
[airplane_geometry]
wing_incidence=2.50000 // was 0
wing_twist=-0.50000 // was 0
oswald_efficiency_factor=0.80000 // was 0.88
----------------------------------------
wing_pos_apex_lon=0.50 // was 3.49869
----------------------------------------
htail_incidence=-1.00000 // was 0

You are now done with the 'aircraft.cfg' mods.

Then, finally, copy the '.air' file from a roughly similar aeroplane (relatively low-powered twin engined taildragger) with known good handling characteristics into your 'Bristol Bombay' folder and rename that file 'Bombay', so as to overwrite the existing 'Bombay.air' file. Back-up the original if you wish.

Personally, I have used and recommend Dave Garwood's excellent Anson as the '.air' file donor.

All this should leave you with a pleasant-handling big, gentle aeroplane with no obvious vices. I don't claim that it truly represents the Bombay - it is just a 2 hour 'quick-fix' - but I think it's an improvement.

Cheers,

Kevin

P.S. If you want to avoid the 'float-off-the-ground' takeoff, just try putting 4000 lb of payload in it. RAF specifications of this era always required aeroplanes to use the small grass aerodromes which were standard in the RAF at that time, so all machines were STOL by modern standards.

G'Day Cathy.

I've got this one in the pipeline, a real early screenie.

It's a Fairey Hendon II circa 1934. And pioneered many of the features found in the WWII heavies. It has the front turret faired over as its supposed to be entered in a period Trans-Atlantic comp. The finished version will have the turret restored.

Hendon

Post by Cathy Howat »

Ooh, nice, can i have one for Xmas, please, daddy? I have been after the Hendon for a long time If memory serves, Did'nt Sir Alan Cobhma use one of these in early aerial refulelling tests with an Empire class flying boat :dunno: Also, what is the Biplane transport that served in RAF transport command in the early years of the war in India, cant' recall the name--any chance of one of those? :think:

Cathy,

I'm without my reference books at the moment, but as far as early war RAF biplane transports are concerned:

Vickers Valentia? - Most numerous, and a proper RAF aeroplane!

Impressed DH-86 Express Airliner?

Impressed HP-42?

After that, we get to monoplanes like the HP Harrow, etc.

Cheers,

Kevin
