Thanks

RE: FLY EAGLE JET models 2012
 

Looks good James! I talked to Chris tonight and he love's it. Said it was just perfect.I can't wait to see it fly. Man that thing is light!!
Thanks for helping with everything to get it to him.

fender i hope this is yours....if it is you better bring her by kentucky...get some photos together

RE: FLY EAGLE JET models 2012
 

Very Nice![8D]

RE: FLY EAGLE JET models 2012
 

Oh yes that is mine, ALL MINE MU HAHA!!!! okay enough over acting lol Yeah I will try just depends on if I have room or not, but I will try :D

Hi All:

Another F14 video from afactory's pilot in China.

maiden flight, dry weight 22.8kg (around 50lb) with two P120, two pilots cockpit set and UAT full.

Thanks

Why does nobody swing the wings? I was for sure expecting to see that :D I understand the CG will shift aft causing a pitch change when sweeping the wings but thats what mixes are for.

RE: FLY EAGLE JET models 2012
 

fender when you get your tomcat going you'll understand why....i have 7 flights on mine and haven't had a chance to swing the wing. 2 things are stopping me from swinging.

1st-the damn speed controller they give you is a piece of ****, it works when it wants to work and i couldn't even retract the wings today. it only opens the wings , but doesn't retract.
they don't even give you the program sequence to program the controller. i spoke to them from china and they recommended to talk to lowell wexler. he doesn't own the tomcat
anymore, so off to the internet to get the program.
2nd-for some reason, my tomcat is pulling right, even with full trim left. so i got to do a lateral balance tomorrow....to see if that fixes the problem.

i mean, you want your tomcat perfectly trimmed so that it would fly itself, then once you get several flight under your belt and all the bugs worked out...sweep the wings and deal with trim issues again. according to lowell, you just need to add 5%up elevator when the wings are swept and 50% reduction on the taileron movement.

or this can happened:

RC f-14 twin turbine crash

RE: FLY EAGLE JET models 2012
 

Mave, I don't remember reducing the taileron by 50%. I did however reduce the spoilers by 50% for wing sweep.

RE: FLY EAGLE JET models 2012
 

Oh, by the way...when you get your tomcat i hope you make a pre-flight check list of the entire plane, cause you'll be surprised how many little set screws and allen bolts get loose or were loose from the factory.

I did a full flap, full airbrake landing today...And all i can say is WOW..how slow i can get her to land...didn't have any tip stall tendencies and she gracefully touched mains first then nose. stayed on power while maintained about 10 degree up nose.....

Then as she was rolling off to the Taxi way the damn wheel and brake assembly comes off. This is why i tell you, and all tomcat pilots to check your plane and then double check again.

Well, that statement goes to everyone in the RC community...

See you in Kentucky

RE: FLY EAGLE JET models 2012
 

hey lowell,


I remember you telling me that pitch was not a problem, but you attempted a bank and the tomcat barreled rolled twice on you..so what i remembered you telling me was the 5% up on the elevator, no spoilers on the swept wing and the 50% throw reductions on the taileron. Again this is from Memory....not saying it's official.

RE: FLY EAGLE JET models 2012
 

Someone else...Don't remember any "barrel" roll issue. Sorry.
I'm sure you'll do fine with it.
Thanks

Lowell

RE: FLY EAGLE JET models 2012
 

Thanks good info here, I always check factory installed bolts/screws etc :D I fly helis so this is normal for me
the video gives no details on that crash

RE: FLY EAGLE JET models 2012
 

Hi All:

FEJ F16 1/5.5 scale with electric gears and gear doors.

See test video

Thanks

RE: FLY EAGLE JET models 2012
 

Very cool, and about Taiwan jets, are you guys selling now cheaper jets like X-treme jets from Skymaster?

RE: FLY EAGLE JET models 2012
 

Are the electronic retracts and electronic gear doors something that can be requested from the factory?

RE: FLY EAGLE JET models 2012
 

Hey James

What about doing electrics on a pair of big blue F15E's?????

RE: FLY EAGLE JET models 2012
 

They have not developed the other jets yet, I wanted them for my F-15 and F-14 but they are still development. Very nice the gear is very fast, I like it will deff have that on my 1/5 some day ;)

RE: FLY EAGLE JET models 2012
 

Hi All:

All of our models, we can convert them to be electric gears without problem. But needs some times to convert them one by one.

Some models with regular gear doors are easy to convert their gear doors, we will do them first, but some are not easy, such as F15E, F14 and F18F gear doors that come with many doors together. Need some more time to figure them out. But for electric gears and electric brakes won't be any probelm.

RE: FLY EAGLE JET models 2012
 

indeed gears are very fast ! i can see my next project having all 3 ,gears doors brakes electric!! keep us updated James excellent work!!

Here are photos to show elevator movement directly.

RE: FLY EAGLE JET models 2012
 

interesting idea, did this design come from flutter issues?

RE: FLY EAGLE JET models 2012
 

Fender...the issue is that, no matter what size servo or how powerful the servo is or how many servos you place in the back.....there is not enough torque to move the stabs INITIALLY. I have Hitec 7955 powered at 6 volts and i have 408 ounces of torque on the servo, but when you put the mechanism and stab together there's not enough torque to move the stab like we would like too. In other words you can lightly press on the edge of the stab with your finger and give full up elevator, the servo has hard time moving the stab. So what 1/2 time show (Robert), Vega (bill) and I have done was buy short control arms and drill the holes for the control rods closer to the center of the servo spline. This gives more torque and stops any potential flutter. Also stops the elevators from drooping or dragging at the field.

The only flutter I had so far was because the 4 bolts that hold the elevator mechanism to the former loosened up and not because i didn't tighten them...they were tight and with thread locker , but got loose because the wood began to compress when you tighten the bolts and with the pressure i guess began to have lateral play. i had to machine a back plate that would act like a large washer in order for the 4 bolt to be torqued evenly and the surface area was increased.

Going back to the initial question as why the changed the mechanism, I even at one point put to 2 servo's on the elevator mechanism to see if it would make a difference to no avail. Don't get me wrong once the stabs starts to move there's no way in hell to stop it from moving or push it in the opposite direction. The problem is the initial movement to get the servo going.

Now they moved the servo to a point in the stab where there servo needs little torque to move the elevator. It has leverage point.

My tomcat is flying awesome, but I'm glad they did the change.

RE: FLY EAGLE JET models 2012
 

Yeah I had already planned on using a smaller diameter metal arm on the servo. I am going to use the highest torque servo I can. did you add any weight to the front of the elevator? I dont have to balance them but just some to help. I would think just a little more weight in the leading edge would help a bit.

Go figure as soon as I buy one they change the design LOL
