RE: F-14 wing terst video
I control my swing wing on the B-1B with a three way switch. The middle position is off and I can control the amount of sweep by switching it to the forward position or rearward position, in small increments. If any thing goes awry, I can put it back to full forward.

RE: F-14 wing terst video
yes its to fast the full scale is some thing like 4 seconds for full sweep
and that fast will cause huge problems in pitch if your cg is not right on
you will also need sweep to elevator mix it will pitch down as they sweep back
good luck

The speed appears to be the same as Bryce Watson's illfated F 14.If you have any concers or problems I would contact him as he had a few flights on his.The only problem I can recall was the tires would leave the rims. BTW that one cool TOMCAT,looking forward to photographing it on my next trip to the "Valley of the Heat" you all stay cool and in the shade.
Raf.. Terst is when the heat gets above 110 degrees and the fingers just don't hit the right keys
or as a fellow Marine said when you have it on full auto......

RE: F-14 wing terst video
Full scale sweep from to 67.5 is approx 53 seconds, but your right, the nose dose pitch down as I find myself trimming a bit when I sweep them aft. Our Target CG is 17% on takeoff, 25% cruise with wings at 25 Degrees, and 35% at 67.5. Hope this helps..

RE: F-14 wing terst video
Joe,
I land my jets better with no tires than with them on. I learned how to land with no tires from all the times the dam Euro fighter tires would roll off at take off. Now with the new tires Todd sent me they stay on and I hardly know how to act on landing.
I gave wayne 2 P-60 Se's to go in that F-14. She will be ready to go here in a few weeks.

RE: F-14 wing terst video
Ron, that wing sweep actually looks a little slower than mine and will give you no problems at all. You will need just a slight bit of up elevator when the wings go back and make sure you dual rate the aileron throw with wings back. On the 12Z I have a delayed up elevator trim that comes in slowly and a flight condition that reduces aileron throw when I flip the wing switch. I do not have 2-3 switches to fiddle with so the workload is greatly reduced; all I have to do is concentrate on seeing it [8D]. My swing wing is also on a 3-position switch and can be stopped anywhere in the swing IF you're quick enough.
Let me know when the maiden is, I'll drive up for sure.

RE: F-14 wing test video
I saw this plane the other day it looks fantastic! twin p-60 is going to be cool. Wayne is an incredable builder it won't go in the air until it's right, I'm sure of that. It looks really good Ron.

RE: F-14 wing test video
George,
thank you for your input I was hoping you would enterject on this thread as a experienced F-14 RC pilot. We have input the mix for the wing swing backat 60% on the elevons and I was thinking the faster the better for the movement. I will definatly call you for the maiden, lets fly the 2 together it will be fun and we will get some good pics as well. Uncle Joe I might have to buy you a ticket.

RE: F-14 wing test video
Here's our entry into the swing wing arena.
http://rcuvideos.com/item/M9SL06SJNDD627F2
It's a drop in fit for DCU / Jetmart F14s but is heavy enough to swing a larger wing. It uses servos and a worm gear. Since they are servo controlled you can program your radio to move the wings back when gear is up and full throttle or move them forward when in a turn or low throttle automatically.
Customer flight testing this summer.
Just attach wings and fly. Comes with former templates. Price $349. http://home.earthlink.net/~matrixmt/id7.html

[quote]
Yup, that's about right Unclejoe, I had two different battery packs that I experimented with which gave me either 5 seconds to go from 20 degrees sweep to appx 64 degrees. Or the slow pack with was appx 7 seconds to do the same.
Some facts and figures and a few things I learned from the flights I had on the first F-14.
Mine weighed in at about 41lbs full of fuel........and 44 lbs with the two droptanks, two Phoenix missiles, Two Sparrow missiles, and two Aim 9 sidwinder missiles and pylons. The jet was 34 lbs empty with no armament or pylons. The weight was part of the reason for the high ground speed on takeoff and landing, thus leading to throwing a few tires from the rims as unclejoe mentioned. My control throws on the elevons for roll were, (measured from the root of the leading edge) 1 1/2 inches up and down when the wings were fully extended and 1 inch up and down when the wings were at half sweep and finally 3/4 inch up and down when the wings were fully swept. As George mentioned my wings were also on a three position switch, but could be stopped anywhere in between. Elevator (pitch rate) always stayed at maximum throw (1 1/2 inches up and down from neutral regardless of roll rate switch or wing position) I usually went to the taileron/elevon roll rate while straight and level of the next wing setting I was planning, then swept the wings and left them there. To be honest, I actually spent most of the time with the rate position for the elevons in the mid (1 inch throw up and down) position and then I was able to fly around pretty much with the wings anywhere I wanted just keeping in mind, it would be sensitive (but manageable fully swept) and sluggish..(very) with the wings fully extended, but I always had plenty of time to hit the switch to full throw before landing.
A few things to note......and dispell any rumours........the JetMart F-14 flew fine with no bad habits. The only reason my first one crashed is because "I" made the mistake of pulling the throttles to idle and entering a dive with the wings fully swept and the jet fully loaded with all the armament (basically, too slow for that configuration with that much drag and weight). With about a minute remaining on the timer that plane probably weighed in the neighborhood of 38 or 39 lbs. There was never any problems with the CG or sweeping the wings at any speed, very stable plane with the wings out and think paper airplane (the pointy one) with the wings swept, that's how it flys.
To do a low pass with the wings swept, I gradually would reduce throttles about 3 or 4 clicks, NEVER push the nose down or its heading for the dirt quick, once I reached the altitude I wanted on the pass, come up on the throttles a couple clicks and it stayed there, then increase to full throttles and she climed out with no problem. I never looped it, but after I almost lost it, when an engine quit and I ended up diving for speed and pulling up hard, I have no doubt it would loop with no problem. (The wings were flexed about 4 inches up, but after that flight nothing was bent, cracked or stressed so my faith was in the design of everything after that point, especially at the weight I was flying at.)
The plane will handle the weight no problem, wings extended or swept, just have to have the speed up while they are swept, for mine it was no slower than about 100mph or it would start to nose over and head down.
With the wings extended and a moderate amount of speed, the F-14 always wanted to climb slightly, not necessarily a bad thing, just something to keep in mind.
The transition from full sweep to full extend I tried at several speeds and had no issue other than you have to be careful of not going too fast and just hitting the switch becuse the jet will pitch up violently with that 4 second sweep, (I did this a couple of times, once in level flight, the second time in a banked turn.......definately raises an eyebrow......but afterwards, no damage or evidence of stress anywhere...also keep in mind, that F-14 weighed a bit more than most, thus the need to keep the speed up while the wings were fully swept, or in transition.) My usual way of bringing the wings forward after those tests was to bring them to half sweep, then slow till the jet felt a bit heavy on the elevator then up to full sweep.........no real noticeable change in flight characteristics doing it that way.
Nice going John, this will make flying this F-14 A LOT more manageable........having auto-sweep will take a lot of the speed guesswork and switch flipping out of the flight leaving the pilot with a more enjoyable experience.

A few of the characteristics of the F-14 can be seen pretty well in this vid, mainly the sweeping of the wings toward the end of the vid while in a turn.......no noticeable change in flight chracteristics, and couple of swept wing flybys.........as long as your speed is up with the wings swept no problem, if you get slow with them swept?
Then add full throttle, quickly or the next thing you're going to see is:

RE: F-14 wing test video
Bryce, thanks for helping out. Your 14 was definitely heavier than mine. I've never weighed it full of fuel, but if I remember correctly, mine is right at 31 lbs. tanks empty, UAT's full. I do not experience the pitching you did when extending the wings at full speed, as a matter of fact it is almost seamless, but that may be a product of my mixing. I was so scared of having too much aileron throw with wings back that I knocked them way down, but now that I have flown it few times, I almost feel like I need to add a little back in which I will do. I also do not reduce the elevator throw at all, it remains constant throughout the flight; I'm not even sure if I have the elevator on DR to be honest. Like you said, the JM F-14 flies great and has no bad habits and actually flies much easier than most people can imagine; it's just a VERY INTIMIDATING aircraft. There are a few videos of mine from this year's jet rally showing the take-off, multiple wing sweeps and landing. I was supposed to get copies, but no deliveries yet.
Ron, I wish I could bring mine with me when I come up for the maiden, but it is just not possible to crate and ship from VA to AZ for such a short time, but I tell you what, that would be one awesome sight to see two F-14's flying in formation, (would probably be a first). Maybe if you head to the East Coast sometime, you can tote your 14.

George,
That looks like it could happen in our life time You guys have provided a lot of valuable info in this thread thank you very much for everyones input. Bryce thanks for the comments and videos I am really getting excited about getting my F-14 up in the air.
We will have to get 2 F-14 in formation at some point.
