Ok The arrow is pointing to a accest panal for the Wires and tubeing going to the turbine. As far as the speedbrake opening forward.Had to do on how I was going to open the speedbrake. See everything has to be mounted on the outside,because with the Jet Tech fuel cells.There is no room to install anything under them. I might add the speedbrake I was talking about pushing the aircraft down and to the right was the one on TOP. Which I do not use any more.In fact I removed the servo that drove it.
