Another Fly Eagle F-14 Tomcat
 
1 Attachment(s)
I missed out on a pre-BITW maiden, so I had to do it after the event was over. Here is some video of the second flight. Nothing too "rigorous" yet, but I did sweep the wings. :) Overall, I'm very impressed with the plane. No stab/rudder flutter or wings stalling on landing. It's very stable with the wings out... when I swept the wings it was a handful, so I'll need to make a few adjustments and try again. The Tomcat is powered by 2 Jetcat P-140RXs which provide plenty of blow. Thanks to Lowell, B1Bob, Ali, and EDF Jim for giving me tips for a successful maiden and Ian for the awesome build.

congrats, what is your final take off weight? and did u use flaps for landing?

Awesome man! Congratulations. Do you need more or less throw on the tailerons with the wings swept?

Not sure on the final weight. I'll weigh the plane soon and report back. I did not use any flap for landing.

Thanks! Less throw with the wings swept, which I had set, but it was still too much. [:@]

Looks good!

It seems as if FEJ has come a ways from when I bought two of their first planes a number of years ago. I'm still not ready to pull the trigger on another one, but its getting closer...

I have yet to hear anyone say that any F-14 model is easy to fly with the wings back - all of them, Jetmart, JHH, Avonds, seem to be a handful with the wings swept.

Congrats!

Congrats Dantley.
Nicely flown! Thank goodness you had all that runway ;) Wow, that looks allot lighter than the one of B1's I fly. Looks like a great set up to me, perfect power as well. You really do need so little movement in roll when those wings come back. A roll gyro would be ideal. Not essential as I first thought, as Bobs is handling ok now when the wings are back, just as long as that roll rate is turned right down.
Regards Al

Bob: This plane has really changed my perception of FEJ. Plus, their customer service is top notch.

Ali: Thanks! Good thing my brakes work or I'd run out of runway! ;) I'll keep reducing the roll rate until I'm satisfied. Does Bob's F-14 tuck in the turns with the wings back?

Ali 10-29-2012 07:12 AM

RE: Another Fly Eagle F-14 Tomcat
 
Thats you rolling into it as you have too much ail movement.. Check out the Vids of B1's at Kentucky if there are any with his set up on the roll and compare to how it was flying at BITW. Also for some reason I found it needed less movement in roll one way compared to the other.. but that could just be a B1 thing :eek: Try wings swept straight and level and rock the ail stick left to right, right to left and see if it all feels balanced. Even with the smallest of roll inputs I can get the Bbunny to roll easily.
I am with D on the perception thing. This time last year I would not have touched a FEJ model, but the more I see of them in action and actually get to fly their newer products, the more impressed I am.

RE: Another Fly Eagle F-14 Tomcat
 
I'll check the left and right roll movement in the next flight. That's interesting that there was a difference.

Hey, and the gear went up on only one system!! Who'da thunk it???!?!? ;);):D

RE: Another Fly Eagle F-14 Tomcat
 
I guess that they have finally listened to the end user here on RCU. That is a real testament to the manufacturer getting the message !

So, I guess that I need a F-16 and F-14..... :D:D

Cheers

This.

You could see even Ali was anticipating the 14 tucking into corners and such.

And Ali had a glorious pass right over the runway with the wings out, he then pulled up and swept the wings. Absolute awesomeness.

I have found with other 14's the CG really does need to move to make it more stable in the different configurations. I will be playing with this with my 14. And it will also get a gyro treatment as well.

The 14 with swept wings is a nose HEAVY delta. Delta's need VERY little aileron and lots of elevator.

If you try to move that CG back, when it gets time to land with the wings out, nose up and slow, well 14's REALLY don't like that. [:@] Ask me how I know.

And the gear REALLY did ALL go up, gear doors close and then all the doors opened and all the gear came back out!! WooHoo! The flight was a bit short at 4 min, but apparently there is room for maybe a min more?

Oh and you're welcome for the moral support D. ;) :D

RE: Another Fly Eagle F-14 Tomcat
 
Of course the gear went up despite the fact that the FEJ guys said you need 3 valves to run everything. If we would have followed their advice Dantley would have sunk over $1000 alone into the air system. As far as I am concerned, no aircraft should have to cost that much to have pneumatic gear go up and down. [&o][&o]

ravill 10-29-2012 10:13 AM

RE: Another Fly Eagle F-14 Tomcat
 
Yeah, I was kinda cringing when I was overhearing the conversation that Dantley was having with the FEJ guys about each gear and the stand alone systems for each gear.

Hi Dantely:

congrats on your F14. Also, it was nice to meet you at BITW. Hope to see you again sooner.

PS: Separately valves will cost $170 extra fee (two more 2 way valves). But I am glad to hear one valve works on his. Good job again.

Thanks
James

True James, add that to the EVSD-5U he has, plus airline, plus festos, plus fill valves and gauges and you have over a grand!! Just sayin...

RE: Another Fly Eagle F-14 Tomcat
 
James, it was nice to meet you as well. I bought the extra EV-2 valves just in case. I'll use them on a future project.

Rav.. Dont worry. We all know he couldn't have done it without you. ;)

Raffi,

why don't you add weight on the wingtips? That way, the CG will move back when you sweep them back.

just a thought

And dantley: congrats on the maiden, too bad i could not make it. Are you bringing it to Lodi this weekend? bring the f14 and f100!!!!! (you should sell everything else haha)

Ali speaks the truth. I knew you were a cheaky, err, smart guy. :)

RE: Another Fly Eagle F-14 Tomcat
 
Its already a tad roll touchy. I dont think adding weight on the tips will make this any better [X(]
Yes there is a C of G shift when the wings go back, and yes its noticeable, but noting unworkable. I still had enough elev to pull up vertical with ease and do that wing swing that Rav liked so much ;) Gotta admit, it did look pretty sweet ( I almost wanted an F-14 for a moment there )

Ali, i did not mean weight on the tip to make it more stable,but to have the CG move back when you retract the wings.

The other option is to have a weight being moved with a worm gear, but that is hard and complicated.
