Putting the rudders this way will cause more flutter since you will need a longer servo arm. If this is done you will have to move the servo to outside edge as well.

The circuits made where of course at full power and keeping the same altitude.

Landing was no problem, I just did not use full flaps so I wouldn't loose speed to quickly, so I added half flaps when I had secure runway and the F-14 landed perfectly.

The circuits whee flown using elevons, very little rudder was necessary.

Hope this helps.
It sure does help. Many thanks for the insight. I have just finished setting up my bird on my the new JR Radio and I am very happy that this radio has given me the programming power to remove 2 gear sequencers and employ more mixes to safely use the wing sweeping, without having flaps interfere by accident.

I own one and am not worried about it. Excellent bird.

Guys I can use some advice, I have been trying to get my mains on my f-14 to function properly. What is everyone doing as far as valve setup or lubing the gear? I have tried several things and still the gear hangs on the up at about 80% full up, I wanted to take the gear apart and clean/lube it but due to the painting SM did after assembly I cannot get the screws out of some parts to disassemble it. I stripped one and stopped so any thoughts? Being only my second SM kit I will never have them paint the gear for me again and if SM is reading this please disassemble the gear before painting if the customer request it. It makes for smoother operation and the ability to take the gear apart for cleaning and maintenance.

Im bringing mine to KY jets, not sure if I will fly due to the lack of time to maiden it before the event but who knows and for the peeps bringing theres just pay me no mind if you see me hovering over your f-14 taking some measurements LOL

Keith, have you tried to cycle it uninstalled from the airframe? Just to rule out some sort of binding related issues.

Regards,
Barry

Barry, I did not but I did disconnect the air cylinder and the gear moves super smooth. I seems like the geometry is off a bit the piston just doesn't have the push on the last bit of the stroke. I have even redone all the air line routing as well. I have also put the gear on its own air source/air valve to make sure it wasn't an air issue. I think when the air cylinder is connected and it's pushing where it's mounted is rubbing causing some binding. Frustrating

As a test just increase the air volume with another tank on one troubled retract. See if it has the last bit of push the piston needs.

Chris, I hooked a large tank to one main gear to see if that was the case but still had same effect.

DNL them Keith.

My F-35 mains are very similar to the F-14 and Im having the same issue.

Have you tried a higher pressure setting?

yeah tried up to 160 psi, you cannot DNL this gear due to the design. I checked that before I even ordered mine lol I hate air.

Why not go with a hydraulic setup? The F-14 main gear design isn't very conducive to pneumatics b/c of the geometry of the actuation pistons.

I would love to go hydraulic but nobody makes a system I can retrofit. Plus I lost my source for machining work when I moved here. If I could get a nice reliable hydraulic system I would convert everything.

Do they have a website? I talk to a guy that had this system in his Mig and he said they were hard to get. I believe this is the same one Jim used in his rafale.

Didn't one of the Aussies convert this gear to hydraulic?

Aussiebart uses the hobby king system with his jets but opted not to on the 14. One of the other guys did, I have asked for details a couple of times but he has never really given much info.

Is Fenderbean the only one with the landing gear issue? Seems as though a number of people are not having problems with using air, so what are they doing right?

I would still do as Barry suggested and try them uninstalled, you might not notice the binding by hand but if it works outside of the jet then it might need to be shimmed, the mount could be crooked and when tightening down the bolts it could be causing a bind..

Mick Burrell converted his retracts on his F14 to hydraulic and they worked perfectly. There are several threads on Hydraulic retracts on RCuniverse. You do not need an engineering degree and do not need an expensive kit or system, it is not difficult. The retracts will need to be removed from the plane and the cylinders fitted with Festo fittings to take 4mm pipe. The pipes will need to be special high pressure tube. You will need a 5 port valve. Ideally a Eurokit one or if not available the UMS HK one. Personally I would buy the HK kit as it is cheap and the valve, tank and pump can be used. You will need a Festo 1 way valve. I suggest you set up the system outside the plane and check it works properly before installing it back in the plane. I use a simple pressure switch to stop the fuel pump but you can use a timer switch or a amp sensing circuit. All the detail you need is in the RCU thread above. 2 guys near me have fitted hydraulic systems to their Mick Reeves Hunters and have reliable retracts as a result.

I have just made up the board for my new plane. I have not much space and have had to fit the items in a space 5" X 5" X 2" mounted vertically like a computer rack. Not very beautiful but it will give you the idea. The tubes at the sides are the connection for flow and return to the small oil tank, the thick wires are for the 2 cell A123 battery. There are 2 servo lines, one switches the pump on until it reaches desired pressure and the other operates the valve to give flow in either direction. They can be Y leaded or connected separately so the pump switch on is timed. (The loop at the bottom is removed and connected to the up and down lines.)
