I have the tanks per the instructions. The center tank is front of the former and below the engine. When the model is full of fuel, it feels very nose heavy....but then in the air it handles fine. I lost a rudder on the last flight, so once I'm done working on my F-16 I'm repairing it so I can start flying it again.
When I get home I'll take pictures of my control throws so you can use as reference. Any other pics you need?
