Did you ever tighten the other side of the elevator bolts? I saw one come loose in flight and that was no fun. Also I had wing plug ins get loose during flight as well. Finally was able to tighten elevators by drilling holes in the long pods in back.
Good to see you makes beat efforts to fix. I wish they would use double nuts with locktite when they assemble these areas!!!!!!!!!!

Following up your build with great interest. I have an FB F-15E from first batches produced, do you know if there are differences/ upgrades done to the kit, Airframe, LG, controls etc...?
Thank in advance and keep up the good work.

I would assume the many of the changes are to streamline production and simplify stock numbers. That's just my guess.

I did balance my stabs. Not neutral but I put a stick of lead in the leading edge of each one. While not 100 percent necessary it does cut down on servo wear and if you have twins this plane can get moving pretty fast and is nice to not worry about it.
You can cut the fuselage where the wing bolts on and tighten up the wing bolts. These come loose over time. When the wing is on you cant see the holes.
I did hidden rudder linkages but... It was a pain lol.

Next video we got some pretty weird angles on the wheels. like they drilled the axle hole at the wrong angle.
So fun!

wow lol not surprised. Gear is the weak link on a FBjet.
they are such good planes though and fly so good.

Would need to remove the lower part of the gear blocks in the plane and install new ones plus some other internal mods on the plane to get the gear angle correct. Not positive on this but would probably need to modify/build new gear well where the wheel sits since it wont be flat anymore.
It can be done but needs some fun work to get it installed on an older one. In the end it would be well worth it. The gear is the only reason I sold mine a while back. While yes it worked for me it was a constant head ache.

Don't forget Sean at Strictlyscale.com sells lots of scale parts for these F15s. Here was mine before I sold it. I loved the plane and the droppable bombs was a fun addition. The moving inlets was a pretty big undertaking though. It did work fantastic in the end. The gear was really the only headache. I crashed this plane on maiden due to a flameout. I was inverted not moving very fast right over the end of the runway. Just didn't have enough speed to get her back so she went right into the trees. Was pretty much toast but I fixed her all up again.
I did every load out imaginable and the plane flew perfect with any load out. No CG changes needed.
Another really big thing is to throw away the big center fuel tank. Get a smaller one made and use that. I did use the stock one but I cut the entire middle out of it and rejoined the top and bottom. The stock tank is simply to large and makes rotation at takeoff challenging. I had mine on scales while fueling and it was 1 lb tail heavy empty and full 1 lb nose heavy. So it changes allot when that center tank is full.

Well we were planning on doing the maiden this weekend. After the taxi test this is how the nose gear looked.
We took it apart and the pin supplied with the kit (8mm Pin) is not hardened at all. Could bend it with your hand.
Fortunately I had a Hardened 8mm pin in my stock and we had a machinist close and were able to make a new pin for the nose.
Hopefully maiden flight soon!
stock pin on bottom. After bending back to get it out.
