The manuals state the TRAINING LOAD for the Spitfire Mk.IX is 7,150 lbs. versus the NORMAL LOAD of 7,445 lbs.
The only details about it are, 'Full Main Tanks, No Ammo or External Stores' but this adds up to 7,202 lbs.
I know it's close, but I am not only interested what of the SERVICE LOAD might have been left out, I want to recreate the correct Weight and Balance for the Spit in MSFS 2020.
The TR. 1133 seems to have been in short supply at some point early in the war, which might have been a reason or the Dinghy might not have been worn. But the latter is only about 20 lbs.
