Rear pipe mounting ring opened up to fit the larger diameter pipe.
Nozzle cone test fit.
Pipe alignment looks good on mockup. I will adjust final alignment after final mounting.
The larger 300 pipe prevents use of the stock AB LED ring. I will order and install a larger one after test flying. This will require cutting the nozzle leaves out and making a larger fiberglass ring. The current nozzle is molded in the closed position like it would be in non AB flight. I will reattach the leaves in the open position like the nozzle would be on the ground or in AB. This will allow a larger LED ring to fit inside the nozzle cone. I would then repaint the leaves to look like the F-16 Block 52 F100-PW-229 engine with composite carbon fiber leaves. I think this is what the Thunderbirds are currently flying.
The B300F fits nicely on the wider engine mounting rails. The final engine rails will be aircraft 5 ply laminated on top and bottom with carbon cloth in a vacuum bag.
Aft intake tube test fit looks good.
