Hey guys, your experiences and opinions please.  Does the F/A-18F fly better with or without a bypass?  I'm also considering a Tam's pipe as I hear his pipe offers a performance advantage.  Your thoughts and comments on that are welcome too.  I'm getting mine ready for the season (late start I know) and I'm kinda in a holding pattern trying to decide which way to go.  Any help will be greatly appreciated! 

See ya on the flight line!!

The air that exhausted throught the pipe are taking fresh air coming from the intake pipe that passes through the engine's housing when doors are closed. Without enough space for the air to pass through from intake it would make your engine compartment lesser pressure. When gear is out, it would take air from the opening but for some reason during retract and one gear failed and left a door open, you would get an unbalance in your jet in the air. Other than that I don't think it will affect flight performance.

I have flown only with the bypass and Tampipe. The setup this way with a titan/160SX has a great sound and remains cool. Mine has been flying since 2005. I have not compared to no bypass but like the full air going through the bypass/tube. The plane is fast too.

Solid performance with the bypass. I dont see much downside to this setup as long as you have a 160 size turbine.

Just my two cents,

Dave

Incredible slow speed on Your hornet. I thought it was going to drop before touchdown as she was flying extremely slow. It gave me hope to build my super hornet and fly her on our rather short field....

Regards,

Way too slow, but incredible slow

here's one of a F18F. it could be slower, but safer this way.

I use half bypass with P160SE and performance is very good. In hot days not so good. I used to use full bypass, but for safety reasons decided that it is better to see start and spool-up.

Regards

Nuno

Landing of your F-18F left me speechless. Never thought that this heavy jet could land so smooth... What's her weight? Any particular setup for smooth take off and landing???

Thanks,

Regards,

Thank you for your comments. Sorry, but I never weight the plane, but I estimate arround 13Kg dry - 17Kg for takeoff.

I made some changes regarding AOA and raised the front gear by 15mm. Also added another harder front spring and kept the original one. Be sure that you use 20-25mm flap throw for take off and that you have a neutral or positive AOA. Mine is neutral. I start to pull elevator way before rotation. Remember that the main gear is very far away from CG, so this will help rotation and prevent scary jumps on take off.

For landing, I use 55mm flap throw with a 4-5% mix up elevator. This plane is a sweet - though it is not a trainer, it is not as hard as some people might think . It is it's 4th birthday this month (I have just knock on wood )

Regards

Nuno

Status: offline 		Those are the nicest F-18 landings i ever saw. Any idea on your respective CGs? Do you fill center tank completely as presume it would make a noticeable difference in cg between beggining and end of flight. Correct?

CG at 140mm and yes, at beginning of the flight, the nose is a bit down because front tank is completly full. I make arround 7 min and leave arround 1/3 of the front tank to make a couple of go-arrounds if needed.

best regards

Nuno

Status: offline 		Awesome landing guys! Just like Nuno I have no angle of incidence, I used considerable flaps of 25 and 50 mm for takeoff and landing resp. My CG is between 5.5" and 5.75", flight time is around 10 mins with approx 1/3 left on my center tank.

Thanks for the comment, that speed would probably good for upwind but I'm getting closer to the center of runway. I came in too fast and high because of the wind so I tried to shortened as possible, it took almost half of the 500 ft runway, if you got bigger engine takeoff would be shorter too.
