In my opinion the Booster 130 will definetely have the thrust (32 lb) to fly your F-18F well and in a scale like manner, the only question remains is in regard to your flying fields surface type/condition, rough grass or smooth sealed? and if long or short strip? For instance if you plan on detailing the cockpit fully and then want to fly with the full the scale ordinance which does add considerable aerodynamic drag, and then possibly flying from a less than ideal field it maybe seriously worth considering the extra reserve of thrust of say the Booster 160 (36 lb). Both turbines are very similar in physical size and specification otherwise. The bottom line and answer to your question is really your flying location....

Cheers- Marty

Status: offline 		Thanks JET FX, I have available 75m asphalt runway for take off + 200m smooth grass filds for landing.
Is this enough for a normal flight of this model?
Since I already have booster 130+ , I will initially use this and if necessary, I will replace with the booster160+

Status: offline 		Hi Peter the Skymaster F-18F will fly well with a 30lbs engine including ordinance set. I used to have one with this setup, please check this videos.

http://www.youtube.com/watch?v=vuc_eImlrhM

This are very old videos from the year 2007... I sold that F-18 to a customer and it is still flying with the Eagle.

Here is a video of my latest F-18F flying with a Rhino (36lbs)
http://www.jetsrc.com/videos/F-18F_JR_2.wmv

I am a bit worried about your 75m runway, you will be in the limit with that lenght...

Great video and great flying.
Is it possible to describe the final round of the landing, the approximate height, break, Flap, gas .....
I have a feeling that the daimondbac accept a lower rate(slower) than the F18 at the last video


congratulations and greetings in Chile
Peter

Status: offline 		Hi Peter the main diference on the twio videos is thast the Diamon backs is from the old verion and the Jolly Rogers is the new ARF PLUS kit. In terms of performance both jet flew the same except for the bigger verticals with the Rhino.

For landing this jet this is what I usually do.
1- Do a slow pass, lower landing gear, apply full flaps and open the speed brakes.
2- Do a complete go around to feel how the F-18 handles at slow speeds.
3- Turn into finals and try to keep the same amount on elevator all the way in. Adjust altitude with throttle. (This is easier told than done )
4- Before touch down make a small flare and you are done.

You have to be very carefull with this jet on landings because it can get to a extremely high AOA and it can basically stop in mid air, opening the airbrakes helps fixing this tendency so when you lower flaps always open the speed brakes.
Be also sure to have the CG at 130mm, this will make the F-18F very stable.

If you wish contact me by email I can send you building pictures and help you with any other questions you might have. info@jetsrc.com

Michel, Would you say that this applies to the SM F-18C as well?

Status: offline 		Hi Peter,

Your G-booster with 14kg is really more than enough for nice scale flying. I flew mine with the old TJT3000 30lbs thrust turbine with SM F-18F. I later found that my engine was not producing 13kg thrust, but she still flew although more slower! She is a floater on finals. I am getting my turbine sorted out as i type. You can go check out Michel Durand's many videos on his F18F with the super eagle 30lbs thrust turbine and it already proves it flies well with it. You will definitely love this Super Hornet, be sure to put C.G. at 130mm for maiden flight, it saved my jet, thanks to Michel's advice

Cheers!

I have some questions, what is the weight without fuel, where is the zero point elevators or anyone has any picture null position elevator for SM F18F 1:8

What do you think the installation of this fier eater ?

Status: offline 		Hi Peter,

Just a couple of suggestions with your installation.

1. I would not put you fuel pump where it is right next to your ecu. The EMF it will emit could interfere with normal function of your ecu possibly causing shutdown. I would put you fuel pump on the floor of the fuselage under the inlet ducting, slightly offset to one side
2. your UAT is not installed correctly. They need to sit with the brass nipples pointing upwards to get all of the air out of the thing so that you do not cause an air bubble induced shutdown.

Hope that helps.

Craig.

Should be fine, although moving turbine another 5-10mm further forward may likely provide cooler turbine EGT's and lower pipe temps and also increase overall thrust output slightly in my opinion... It would pay to experiment, then compare EGT variations at max and idle RPM's.

I have only to insert servo flap and model will be ready for first flight.
I have the feeling that a little too heavy 13.8 kg dry, what you think?

When I start she lifted nose very high then she was a little nervous because too mach elerons and Elevators. On landing, I broke a wooden board, the left rear suspension.
Please look at the video and tell me what I did wrong.
Yes now I know that I was too fast on landing
Suma -sumarum I like it
