Widebody 60 Equipment
Azuz,
Just make sure it doesn't vibrate.
If you find it vibrating later, you can put a piece of sponge around it. This will require you to change all the elevator linkages to ball bearing parts. absolutely 0 slop.
As Thomasr suggested above, Fuel tank on CG with 91FX/SX will need Perry Pump VP-30 regulating pump. (blue).
The location of the full tank will be under the canopy. I think MK & OK model tank will fit without any modifications to the cockpit.
