Leading edge of my main gear assembly slightly separated from the fuse. I forgot to get a pic before fixing it, but has this happen to anyone else? I didn't even see it at the field, I probably flew like this. I put some glue & 2 pieces of metal tape, hopefully it doesn't happen again.

Help pls............
I picked one of these up used (F-16) and had a couple of questions. It is the latest version with the newer servos and revised CG. I noticed the down elevator to throttle mix is still active. As you increase the throttle, it gives down elevator. Should I leave it? If I need to change it, how do I? The previous owner did not notice and flew it this way..........any suggestions.
Also, the previous owner moved the turbine back about 7/8" to keep heat out of the fusealage. The tailcone of the turbine is now about halfway in the bell. Will this hurt anything, or should I move the turbine forward?
Thanks

My F-16 is just about ready to fly. I figured out how to turn off the elevator to throttle mix. I'm running everything in the stock configuration.....all servos go thru the board and then to the RX. Control throws per manual. CG is at 178 mm (per manual) gear down, tank empty, UAT full. I had to add 3 oz. under the front of the cockpit. I'm running 2s lipos for the RX, I guess I should have used 3s.
Any recommendations?

I did not have high expectations when I was about to maiden the F16 but it has turned out to be a surprising nice little flyer. I have about 15 flights to date and it has held up very well.
I would suggest cycling the gear prior to every flight just to sure that everything sequences and pressure is put on the locking braces. Check the nuts / bolts of the gear every 4 - 5
flights. Those little tires have to rotate really fast...lol. I also check the bolt holding on the stabs every couple of flights as well as the overall integrity of the stabs. they have worked well in flight but I would be concerned about the little plastic mounting tabs if the stab was ever damaged , kicked or jammed while moving around.
Otherwise she has been just fuel and fly...
4:30 minutes with mixed throttle / K60 power.
CG @ 185mm
All control throws per the manual but I have increased the aileron throws by an extra 5 mm.

I had a dozen flights on my f-16 before the horizontal stab departed mid flight. She flew very well and was easy to land, even on a 300 foot runway. She grooved very well and was almost immediately comfortable. The landing gear was a constant source of frustration and only worked properly a few times; the main doors would often stay open after the gear retracted. The front most mount for the main gear cover departed the aircraft, along with a part of said cover on the first flight; I bought a new cover and 3D printed a new mount. I would recommend inspecting the foam to plastic joint on the horizontal stabs regularly and maybe reinforcing it with a couple through bolts as there is nothing holding it together but a little glue. She did look and fly great though; because of which I have seriously considered getting a composite F-16.
I have 61 flights on my V1 Super Viper. She flies extremely well and lands very slow. She has had a plethora of issues though, mostly glue and servo related. I have replaced all the flight control surface servos with larger Hitec units (the new SV comes with larger servos as stock) as one flap servo failed in flight. I have replaced the starboard landing gear mount with hardwood rails because the original detached and broke multiple times. I just recently had a hinge become unglued. The glue had also started to let go at the wing mounting. I did add in a second 24oz tank where the newer versions have their smoke tank; this gives me 8 minutes before my timer to land comes on and I have plenty of fuel for a few go arounds. I also added a carbon fiber spar in the vertical stab mounting area. The foam dings and gets dirty easily making the plane look old before its time. But... despite the issues, she's still a favorite to fly.
I also have an HSD 105MM EDF J-10, which doesn't get flown much anymore. All of my HSD jets have had a glue issue in one way or another: it's something to keep an eye on. They, however, all do fly well.

I think it is only fair that when you mention that your stab blew off that you also mention you stuffed a 100 in this little jet.
