Hey guys can someone confirm the routing for the servo leads in the wing? I drilled a small hole in the area where the red line is and I dont see a way into the wing. I have looked from the servo box area as well and the only route I see that doesnt have a rib in the way is the yellow line. The area between the big and small carbon rods is covered by the wing mechanics and will not support my sbus robbe plug. Has anyone opened up the area around the red line to and is there maybe a small hole I cannot see? thanks

Just a heads up regarding the carbon wing tubes. Ours become loose and eventually we were able to just pull it out. Make sure you check all of yours if you own a Skymaster F14.

Just crazy that's a really big deal because you could easily have one that would be fine on the ground and then come loose in flight. Just crazy to have to worry about things like this at the cost we paid for the kits. Did you forward this to SM?

Goodness how do you test for that? Pull on it really hard?

I don't even know you would fix this without major work to the wings. It's not like a large 3d plane were you have a bolt or something that holds it on the tube.

I was thinking of drilling a small hole into the wing and carbon tube then tap it to M2 and use a countersunk bolt just for security. I haven't decided to do it yet, a bit more thought perhaps... As you say this is whats done on some of the other jets I'v but mainly on stabilisers.

yeah but my worry is how secure the tube is inside the wing, its not like a plane that has holes cut in the ribs with a guide tube. If they didnt get enough hysol around the carbon tube you could essentially have the tube develop slop. The channel for the carbon tube is square and the shaft being round would need a good solid beed of hysol on all four sides to fill the box around the rod. I can see the carbon rod in the wing in some places and the hysol is not done very well.

Hi all,
Is anyone setting up their F14 with a JR 12X? can someone please share how they are setting up/mixing their swept wing so that it disables the flaps?
I am trying regular mixing but it only covers two flap positions, position 0 and 1. Any help would be greatly appreciated.
thanks in advance.

How did the performance test of the full function wing go compared to the standard wing?
Was the extra weight worth it?

Trying to understand, are thr retracts and other accessories electric or air driven?

Thanks
Tony

On the carbon rods: there IS an outer tube in the wing, so applying a good dash of glue will solve this. No panic!!!

The client is now ready to take delivery so the last few checks have been done before I drop it off at Motors and Rotors for its LMA inspections. The below pictures were taken a few months ago and are missing a few of the details as it was just a preliminary test. One of the turbine had to go back to JetMunt to check out a starter motor. All back together again for another test over the next few weeks.

I was sure you would have flown this before I finished mine, they fly great only bad thing I experienced was it snap rolls if you get to slow in the turn without any flaps. Almost had a bad day on the third flight, I test flew mine with four pheonix pylons, bottom tanks and the sparrow/sidewinder rails. I will add the missiles once I get more flights on it. I had to fix some flap slop on one due to the rod guide being wider than is should be. Plus the nose steering is sloppy and needs some work to remove play in the neutral position. It flies very nice and landing was stress free. I still need to add my detail kit I bought from you but I will get there eventually. Cheers!

Hi Alex,

She looks fantastic mate, especially with your details on board. Did you modify the nose leg/steering at all?

Hi Keith,

Did you get any nose wheel shimmy on yours? I have done quite a few mods on my nose leg to sort it out and hopefully those will avoid the shimmy issues others have experienced. I have reduced the slop in the steering by a large amount....hopefully that will help.

Hi Guys,

Thanks

Have you got any pictures of the nose wheel mods? Be interested to see what you guys have done.

Cheers

So far the only mod I did was during the build, I added a second set screw to the top arm. If the slop is from I think is then I will be adding some shims at the bottom, but that will have to wait for a few weeks I will be gone for a month starting tomorrow.

hi all, i built one for a friend in australia, and found what i believe to be the solution to the nose leg shimmey. the actuating rod between servo and nose wheel bogie is approx 3mm, it seems to get a twist as speed is increased, then springs back, twists, springs back etc. my fix was to roughen up the vertical steering rod, hysol a carbon tube over it and then a brass sleeve over the carbon to stop it splitting. not the most elegant solution but worked fine. unfortunatly the model was terminally damaged after landing on an otherwise excellent test flight. perhaps replacing the vertical rod with titanium push rod? any engineering typs out there can run a quick calc on twisting moment of steel vs titanium. i don't believe the motion comes from rod to arm join youtube video https://youtu.be/pr0I0beYieY

I have a general question about F14, what should be a good starting CG position ( in procent of cam ). I was thinking around 25 procent.( or a bit less)
Do you agree with that number ?

Thanks

or easier, could one of you measure the distance from the nose to the position of the two balancing screws required to balance the skymaster f14

thanks a lot
