  • Current state of my F-16 repaint. Some of the decals from Callie were a little large, so I've asked her to redo those. Just need to add a few more paint trim items and cover it with 3 coats of Minwax. But I will probably maiden it on Sunday anyway.

    • Better pic in the daylight.

      • The revised decals came in from Callie today and they are perfect!

        All I have left to do is paint the dark gray trim on the intake lip, then hit it with 3 coats of Minwax.

        • Did the maiden yesterday at our club Fun Fly. Everything went great except for the landing. She survived it ok, but I have a few small plastic pieces to replace on the nose gear. The colors really popped in the bright blue sky.

          My issue was I was landing right to left (left to right is my normal pattern). At this particular field, which we lease from the city and is right next to their maintenance yard, they have dropped in a fenced off construction equipment area off to the right of our runway. The edge of their 6' high fence is about 20' from our outer boundary, which is then another 50' to the edge of the runway. My approach was too high and I went around once, but came in high again and was going to go long and we have very little overrun. Didn't want to put it in the bushes, so I bounced the landing.

          Everything is fixed except for two minor parts. One of the plastic collars holding the nose strut in place broke, and the pins on one of the front gear door hinges broke. Those items will be ordered from Motion tomorrow. Thankfully both are in stock.

                    • So, a while back I changed out my stock edf for the FMS edf unit. Performance was ok stock, but the FMS unit gave it the extra punch that I wanted, and was giving me a bit better flight time. Now, I'm having stealth issues somewhere in my F-16, and I can't figure it out. Around 3 flights ago, about 1.5 min into the flight, the throttle became intermittent. It would buzz like it was going into LVC, then come back for a few seconds, then pulse again. I managed to get it back on the ground in one piece, so I began troubleshooting. The battery I was using was fairly old, so I figured that was the issue.

                      The next weekend, I took it up with a brand new (<10 cycles) 70C Revo Gopack 6S 5800, and had flown previously without issue on the F-16. What happened was a mirror image of the previous attempt, it cut out and became intermittent halfway through the flight, and I nursed it back on to the runway. With the battery eliminated as an issue, I thought it was probably a solder joint on the FMS fan. Since the plane had run fine stock, I figured the ESC was probably fine, but gave each solder joint a tug to check that it was secure. The FMS unit plugs also seemed secured, but I re-soldered them anyways just to be safe.

                      That brings us to this weekend. Brought it out again, and it flew fantastic.. For the first 1.5 minutes. Than the pulsing started, and power become intermittent yet again. But this time, I was at the furthest point out in the pattern. I put the gear down, and set a glide slope back to the runway. I few seconds later, I realized there was no way that I could get back to the runway. All thrust was gone. I put the gear up, switched to high rates, and tried for a soft landing in the grass about 200ft short of the runway.

                      Upon surveying the damage, it actually wasn't too bad. The intake is slightly wrinkled, and the nose gear door ripped off. Appartently, the gear had fully retracted, but the doors hadn't closed yet by impact. The battery and canopy had ejected and were unharmed, and the rear fins and some of the ordinance had broken off. Not terrible, but annoying none the less. So, my suspicion is now on the ESC. Has anyone else had a similar issue on theirs? Any advice is appreciated, I'm just hoping that I don't need to replace that expensive ESC..

                      • Check the timing on the ESC... if on high, I would go low and see if that solves the issue

                          Sounds like an ESC issue. If there is a way to test the FMS motor and then the stock motor on the ground with the current esc and then a new esc then I would. Also are you getting adequate cooling to the esc? It sounds like it could be hitting a thermal cut off as well. The stock esc will shut off completely if the temp gets too high. And as another person said. Check the timing because high timing will increase amp load and heat but not always give you more power.
                          I have way too many planes to list off... But I love to fly them all! the 80-90mm Jets are my newest addiction! Also check out my youtube channel for TONS of flying footage. https://www.youtube.com/user/gooniac33

                            Are you using spray minwax??

                            • I'm going to try out low timing next. Thanks for the advice guys, the thermal cutoff seems to be most likely what was happening.

                                I brush it on with a fine paintbrush (foam brushes work too). I never really liked the spray version.

                                      Welcome! Great video and flying! Yea...nice runway, but those trees look too close for comfort, or at least for low fast passes.

                                      I've got over 150 flights on my FW F-16 flying from grass, so the gear has taken a beating. However, it's still my favorite EDF jet and still going strong.

                                      I'm guessing you fly Herks from Dobbins? I'm retired USAF myself, Airfield Ops Officer. I was a 2-time air boss and Air Show Director during my career, worked with the T-Birds for 3 of the 4 air shows I worked. Now just about every weekend is an air show with my T-Bird F-16...without all the crowds.

                                        Thank you very much sir! and thank you for the compliments! Yes CCRC is very tight for these beloved EDFs but I like the challenge!

                                        Yes sir I do! I'm a pilot with the 700 Airlift there! Glad to see other military guys on here! That airshow business can be tough. We are in the process of putting together the 2018 one at dobbins now I think I prefer the "personal" air shows my self Nice to meet you and glad to be here!
