Mine flew perfectly with the C of G at 155mm and all up weight of 23 lbs.

Congratulations Eastern for your flight.
What ver.you have F-16 advanced or the regular?

Juan.

Its the 1/8 th scale, an early model that I bought second hand. Out of interest has anyone bought the Hawk that was being offered discounted by FEJ? It seemed excellent value, I was offered one but dont have a big enough turbine so turned it down (regretting it now!). The one thing I have to say with jets is AMAZING, the sound, smell and the whole theatre of them is just so damn addictive, Im just so lucky to have an old WW2 airbase at my disposal! All I need now is a tanker full of Jet A1 and the weather to get better.</p>

Have fun everyone</p>

Can you post a photo of your F-16?</p>

Starman62,

Sorry missed your question! I have 17 flights on the F 16 now and have been moving the COGmore rearward each time. I am now at approx 160mm and with a head wind I can land quite slow. No head wind and you notice the difference in landing speed. First flights with COGat 140mm landing was uncomfortably fast.

Plane does it all once set up properly, inverted split S,<strike> </strike>immelman etc etc.

Note I like rearward COGplanes, but you pay the price if you stall it!!!

Mav

Hi guy's,

Mine fly with C/G between 150-155mm, I had test from 140 to 150-155 and I find the C/G at 150-155mm is perfect ! In particular for landing. If you move the C/G after 155, I find the landig is strong for the rear of the plane, thatt touch the tarmak.

Nice to read you take a lot of pleasure with FEJF16 as mine !

See you

Alex

I keep forgetting to ask this question, but does anyone with a FEJ F 16 1/8 or any other for that matter have problems with gear doors blowing open during high speed ops???

I guess this is simply because we are not using a bypass?

any ideas on a fix?

Mav

mav, dont seem to have that problem, maybe your do cylinders arn't holding the pressure, you're nottrying to do mach 1 are you lol.

todd

Hey Todd,

Did you go to the Adelaide jet meet on the weekend? I hear Paul had a problem with the big F16?

What's wrong with a full throttle dive from 1000ft LOL?

I am using the airpower gear door cylinders that work perfect on the ground. I run 100 PSI at take off for gear and doors. What else can I do?

Mav

I use peters, from intarico, door cylinders they are stronger and I have never had a problem.

My hornet has them and they work fine on that model.

I will let Paul make the anouncment on the 16.

The jet meet went very well, we used 580ltrs of fuel and everybody enjoyed themselves, my hornet had its debut on saturday and flew fine and had a hissy fit on sunday must have been the cold,but it is still alive, just.

todd

any word on that new F-16 that went down due to wing failure?

OK, maiden flight completed and it's still in one piece.
I have the advanced version with a P-80SE and this is what I noticed from the first flight:
 - too heavy at 25.0
 - CG at 148 is way too nose heavy (for me)
 - all control throws set to recommended and so far, fine

Seems most who posted weights are 3-4 pounds lighter, not sure why mine came out that heavy.
I'm working on moving the batteries back now and will shoot for a 155-158 CG.

Great job on the maiden. I was a little concerned on that long takeoff roll. A little tweaking on the CG and you will have a great flying bird.

What long take-off roll?  You mean your not supposed to use 790 feet of a 800 foot runway?

I was waiting for it to rotate on it's own but...almost done moving batteries so we'll see how it does next weekend.


Craig

Next weekend you are only going to have 600 feet. What to do now.I know, we will build a ramp to put at the end of the runway. That outta launch it.

Hi Craig.

The new P-80SE is a fantastic engine but about 2 lbs heavier than competitors ( including accessory kit ) ...

Congratulations on the Maiden Craig! I think it is a fantastic flying jet.

Now I presume you are talking about a FE F16? Is it the advanced version or Plus? COGat 140mm IMO is just way to nose heavy. I am around the 160mm mark and very happy with this set up!

Cheers,

Mav

Thanks Mav, I do think it will be flying just fine after a CG tweak.
Yes, it's the FE F-16, advanced version and the CG was 148.  I moved one of the batteries to end up at 155 and will try again this weekend.

Craig

hi all,

just orderd the F16 1/8 advanced version. and just wondering of the Kingtech K-80 would be good for it? any advice??

Karim

Karim,

I think you will be fine with a K 80 as they are getting good feedback. Might be a struggle off grass however unless it is a very nice strip!!

Mav

Hi Mav,

am not gonna fly off grass, so that wont be an issue, do i expect flying with 3/4 throttle??

Karim <br type="_moz"/>

Well at long last made a start on my F16, all excited now but please gents a quick question fitted the bellcranks tonight plus the elevators servos, and found that with the servo arm vertical and the elevator horizontal the supplied threaded rods for the linkages appear a bit on the short side their only threaded in a few turns which does'nt go well with me so guess i'll be buying some new threaded rods, anyone else come across this, mines the advanced version.

Plus have read lots on this thread about a front gear mod to stop it folding but no one mentions what the mod is, grateful for any advice

lozza

Lozzo, I bought a fej f-16 and yes I did have the same problem, its funny you mention that I have bought an original first copy of the fej 16 and all the arms and front undercarriage are alot better design than what we have now.

You are going to have to buy new arms, dont try using those ones.

With you front undercart take it completely apart and check all components are cleaned of metal barbs.
check to see how the retract block sits on the air ram arm, you may need to do some filing.
with the sides of the retract unit check to see if the retract arm is going into those grooves properly you'll find if these do not go back far enough this can cause the retract block to inadvertantly collapse under pressure i.e on landing. because it is not sitting on that arm properly.

have a go, just a few ideas.

regards
Todd

Karim,

Yes I would imagin 3/4 throttle with a Kingtech 80. It will probably take a while to rotate on the first flight as most (including myself) have COG too nose heavy to be safe. You can simply move it back each flight until you are happy and it will then also rotate easier and quicker!!

My only other problem now is that my main saddle tanks do not empty at the same rate (not using the third tank) which is annoying. Obviously the pick up on one side is more resistant than the other side. An ideas here??? All in all very happy with FE F16!!

Mav

My last 2 flights have been at the rear-most recommended CG, 155. To me, it's not enough and I'm wondering who is beyond that. 160 or more anyone?
Mine came out heavy overall but the CG still seems off.

Craig
