RE: Yellow F-18 wing failure
I figured it was an early version. I tend to buy things when they first come out Just like the F-18 2-piece Twin.
The plans showed how to build with the wings fixed but also told you how to make them plug-ins. I went out and measured that
little hatch and it is only 3.75" in length.

RE: Yellow F-18 wing failure
Thanks Dave - its the VFA-82 Marauders ShowBird scheme used by the CAG, something a little unusual.
It will be a few weeks before the first flight, as I need to put the detail on as yet and fit everything back into her then check everything out. Thankfully I made all of the internal bits fit onto removable plates and is easy to put back together and maintain. The whole engine/bypass and pipe can be fitted in 10 mins as I have used a generic framework with bolt on formers – this means I can use any combination of power plant just by changing the mounting plate. It’s just the RC cables and actuator tubing that will take the time to route etc
Will post again once flown.

RE: Yellow F-18 wing failure
I built one of those planes before they even had the scale gear for it. It flew with Jet model products MK20 gears from his old F4 Phantom kit!! and OS 77's. Kind of a SLED though!!
It is an OLD airplane that has gone through many revisions.
Sounds like it's going to need another update to keep up with the turbine technology.
One of the best F18s out there, just the same.

i know this is an old thread but knowledge never gets old and can help save someone from big problems. i've been flying turbines for about 7 years now and i've owned nothing scale or substantial . i never got into scale stuff as 99% of our runways are grass and i thought the airframe and gear would get beat up too much. that being said , we now have access to a awesome place to fly so i decided to give it a try. . i have flown heavy WWII fighters for years and had a boomerang intro a long time but i still question weather or not i'm going to be flying above my paid grade. i didn't realize the size of this f-18 when i bought it and question weather my Kingtech 140 could even fly it providing i keep the weight down. my thought process was if i keep it really light "no cockpit , no fancy power boxes with batteries etc , that it could be done. by adding more weight like fuel more/bigger engines that you would need the extra power just to compensate for the extra weight and on and on....
Telling my friend about my new ride, he advised me to get on here and check out the wing issues that the 18 has as he said he saw two lose wings over the years so here i am.
My point/question is ... if i provide pictures can this plane be dated and given the things that i just talked about, can i flying it ok. I KNOW you CAN NOT compare this to the yellow but i have several G&P hornets over the years "they are pusher props" and can't believe how well they fly and land. though not for a beginner you still have to setup the approach right or you won't have a good landing. every video i see , guys are coming it at mach 1 . can't you do a better approach nose high flaps down and power on? just some thoughts to start a conversation and picking up some tips. i have alot of questions. WB_1 thanks in advance

Hi Warbird1,
I just finished up a yellow twin F-18 for twin EDF, mine is 41 pounds loaded with 12s 8000 mah x 2
I've studied up on this plane and as I'm sure you know the issue with wing failure comes from the thin areas on the forward and rear main spar formers. If you have the single turbine version this is not an issue as the formers have much more material in those areas. With mine being a twin EDF for large Tam Jets 128mm Dynamax conversion I had to mod my formers for extra strength. I sandwiched the main formers with 1/8 carbon fiber, which is what most of the guys have done with this plane. Since you are looking to do single yellow does sell aluminum braces that may work for you.
Put up a couple pictures of your main spar formers when you get a chance

I'm building one now for single amt 450. Mine is the old polyester df version. I bought the new formers from yellow. They look to be up to the task. I will use the stock wing set with some mod work of my own. Definitely will not be drilling a hole in the aluminium spar.

The inner holes for the flap hinges are pretty close to the spar. The first is about 1/2" or so and the gradually get deeper. You just drill to the spar and cut the hinges down a bit.

I believe those are pics of the G&P pusher Hornet he was talking about earlier.
I'm building one myself. Cool little bird. I believe people use the gear from the yellow 1/10th for this kit quite often.

dale , fortunately in America we do have the right to express or opinions .. good , bad or indifferent. i wouldn't let it ruin your day bud. i realize that the thread is 8 years old and that that doesn't matter if you can still get useful info from it. so if you have anything you'd like to add , that's awesome . the day you stop learning is the day you start dying .

Warbird, my comment was targeted at Desertlakeflyer. He obviously is attempting to compare the Yellow bird of 10 years ago to the failures of FEJ today. If that is incorrect, please educate me.
Thanks for waving your flag though, if I'm correct, and I know I am, mine does the same.
My day can never be ruined by such rubbish, I had hoped this thread stay on course and my comment was intended to educate where I thought a misunderstand had taken place.
