ID:	327912 months ago. Totally my fault, lost spatial orientation turning from base to final leg when I had taken it out way too far. I think it stalled and went straight in. I was able to harvest a lot of the plane, and put them in a new F-4 I just got a few days ago. This will be same paint scheme, but doing a few more details on the plane this time. I'll attach some pics of the new cockpit and the pilots glued in before I attach the canopy. I'm portraying an N model, circa 1975. This is VF-84, the Jolly Rogers. I'm looking forward to the maiden probably within the next several days.

        • On the "final assembly line" at home, waiting for better weather to do the maiden. I took a lot of the "guts" out of the crashed previous plane, which was painted identically to this one. This plane has the Chris Wolfe Afterburner lighting system, and JP brakes to help stay on the runway where I fly from. Have started some panel line shading, exhaust streaking, and some judicious use of some oil and grease acrylics on various parts of the model, like flight controls Click image for larger version

              For the time being, I just put all the old stuff from the last plane in this one that was still usable. I originally had the 6S outrunner which is adequate for my style of flying, but I think I'll probably go with a 6S inrunner down the road.

              Which 6S inrunner do you recommend, again?

              Thanks,

              • That's the FMS 90mm 12 blade installed in the "old" F4 ...bit of foam sculpting required but no big deal. Sounds a bit louder (in a good way) than the Freewing 1835kv motor. Unfortunately only just finished and it's too dark to "maiden". If it's a flying day tomorrow I'll give it a whirl....fingers crossed !!

                    I put the FW 12 blade 1835 Kv inrunner in both of mine and it made a huge difference in the way it flew over the original 9 blade outrunner. I've put that fan in all of my 90 mm's and really like it (although it is a bit pricey ), but imagine the FMS fan locharrow put in is similar if not even better. The FW fan is a drop in fit requiring no modification. Can't say about the FW 9 blade inrunner as I don't have much experience with that one (did put it in my Stinger 90 when I swapped in the 12 blade in my 2nd Hornet), but it is considerably more economical. I'm sure I probably fly similar to you as I'm not a speed demon and rarely use full throttle, except on take-off. The big difference for me was in the take off distance on grass now less than 70 feet and it powers through any vertical maneuver like Cuban 8's and Split S's without missing a beat. The old stock outrunner seemed to labor a bit at the top end of a vertical maneuver and occasionally got too slow causing an early wing stall and a "what the hell" moment. It also powers through slower base to final turns without getting a little loose and can recover quicker if you need it. There's not much difference in flight time though and I'm getting 4 minutes on an SMC 6200 where I used to get 3:40 on the outrunner. But you can tell the difference in the flight as it is a lot smoother and holds your desired air speed easier. Just my 2 cents.

                    • Thanks for the info, Hugh. This old 1835Kv outrunner is still in great shape, considering I used to fly it in an SEA scheme F-4 years ago that is now hanging in a hangar in Powell, WY for the CAP kids, and then flew a bunch with my plane that recently crashed due to my letting it get too far out, but was totally unscathed from that incident, to now in my new replacement F-4 that I had hoped to maiden this weekend. As luck would have it, the flap switch on my DX 18 broke off yesterday, still a nub of the spring sticking out of it. It does "work" but I would be foolhardy to try and maiden this F-4 with that goofy flap switch. So, tomorrow it gets shipped to Horizon for them to put a new "D" switch in, and I'll do the maiden when it gets back. The plane is fully ready to go, otherwise.

                      I think once I get the new F-4 all dialed in like before, I'll look into replacing the fan with what you recommended. We are at 5,000' MSL here, and I think there is a probably an appreciable decrease in power from what you probably find in the Miami area at sea level where you fly.

                      Do I need to change out the ESC or anything else if I go ahead and put the inrunner in place of my current fan?

                      Thanks,

                      Dave

                      • davegee the existing stock 130 amp ESC is fine for either the 12 or 9 blade inrunner and I suspect would be OK for the FMS fan as well. Considering you have the 1835 Kv outrunner in it already, then I'm not sure there will be that much of an upgrade. I got mine when they first came out and both had the 9 blade 3748-1750 Kv outrunner (same fan in the older F-18 as well), so for me on the F-4's and F-18's, going to a 12 blade 4068-1835 Kv inrunner was a fairly substantial upgrade. You may be better off not wasting money on a somewhat minimal upgrade if you're already happy with the way it flies.

                          Thanks, Hugh. I'll certainly consider an upgrade down the line. I think one problem I have is that I am at over 5,000' MSL, and I know that that causes some degradation in performance versus sea level, probably with whatever I put in it. I just don't know if any extra punch from the upgraded fan will be enough to justify the cost.

                          I'm having to stand down from doing any flying and the maiden of the new F-4 I just got due to the flap switch breaking off on my DX18 transmitter. I didn't feel comfortable trying to work the flaps with the nub of the switch sticking out of the transmitter, especially for a high performance jet that will command all my attention, so I shipped it back to Horizon to get a new D switch put in. So, I'll have to wait probably until sometime next week to fly again. But I should get a good idea if the F-4 needs some more power for my field elevation, and my flying style once I can fly again. We'll see.

                          Appreciate all your good comments.

                          cheers

                          • Rain and wind has prevented "maiden" with the FMS 90 since installed but managed a few fast runs yesterday (no flights because of a few dog walkers) seems very promising .....

                            • "Maiden " today with the FMS 1850 ....to be honest, compared to the Freewing 1835 ........nothing in it. The grass is longer now than the last outing with the latter which might make a difference but in the air a difference was not apparent. HRB 6000 cells all above 3.8 so no change there either. So there we have it . What it does have going for it is a very nice sound.........Time wise I just stuck to my normal 3 1/2 min. from wheels up to wheels down. You'll be glad Hugh....saved you a lot of money !!

                                glad you got it down safely on the maiden and got some good information on that motor's performance for comparison.

                                  Thanks for the info, was wondering about that fan as well. So now for my next "pet recommendation", the SMC batteries. I'm not sure if you can get these overseas and if you can, they may be price prohibitive, but after testing tons of batteries and literally going broke doing so, I've settled on the SMC's being bar far the best. Compared to Admirals, Spectrums, Roaring Tops, Venoms, and even HRB's, the SMC's test out with the highest C (despite what labels say) and the most consistent and higher individual cell amps. Their batteries test out to the labeled C, which is higher than any 100C labeled competitor. HRB's aren't bad, in fact better than most I've tried, but not as good as SMC. For that higher actual C, they still don't weigh as much as you would expect. For example, comparing the SMC graphene 6200 40C (weight 814 gr) to the HRB 6000 50-C100C burst (weight 830 gr) I've tested the 2 batteries with that 12 blade 1835 Kv fan:

                                  HRB 6000: Actual C (Progessive IR Meter) at 34C
                                  Power Draw fully charged at 100% throttle: 123.2 Ah and 2782 Watts

                                  SMC 6200: Actual C at 41C
                                  Power Draw fully charged at 100% throttle: 127.6 Ah and 2947 Watts

                                  I'm getting 4 minutes now with the SMC in both F-4's and come down in the 3.8 range as well. I think I'm getting a bit more time since I'm at full throttle less to achieve the same flight parameters (on grass as well), but can't guarantee that since I really have no idea what I'm doing out there, flying by the "seat of my pants", and those pants aren't always dry!

                                      Well, feeling just a bit "snakebit" with my F-4s these days. I had one, got abut 22 flights on it until I let it get away from me a bit and took it out too far on downwind leg. Got disoriented because I couldn't see it all that clearly, and apparently got it too slow and stalled it turning final approach leg. Totally my fault. Lawn darted it.

                                      I harvested all the innards of the crashed plane into an ARF Plus plane, same markings. On the maiden, it was flying well, but I got it a bit low turning final leg, "goosed" it a bit to make sure I had enough speed, and looked like it would be a normal landing. Wrong! About 5 feet above the approach end of the runway, it stalled and snapped to the right, landing pretty hard. Nothing damaged on the gear, ESC, all that stuff, but did tear the forward fuselage badly near the cockpit.

                                      I took it home and repaired it. You probably wouldn't notice it got damaged and repaired, now. However, because of the damage to the fuselage and some crushing of the foam on one side. when I put it together, I knew it was slightly "bent" and would now have to be retrimmed to its new state of being.

                                      Got a few flights in, including two today. Thank goodness for Flight Modes in my Spektrum transmitter, as I had a lot of trimming to do in all configurations in the 3 minutes I could keep it up flying. Now, although the flight control surfaces (mostly ailerons) show that it is "bent," it still flies pretty well. I think it will be a keeper for the time being, maybe eventually load everything into another ARF Plus someday. But for now, I think it flies well enough to use it as my F-4 trainer and get better flying it.

                                      A couple pics taken from my local flying field this morning after the flights.

The wings have been cracked so often they are now 90% epoxy............... But .. when it's in the air on a low pass or screwing up vertically with drop tanks and missile it is still the D B's

                                          Wow! That makes me feel better! Great job and tenacity keeping those birds flying! I love the part about climbing a big tree to retrieve it!!👍😁

                                          I had one time when I was l learning to fly years ago with a glo high wing trainer. Just me and another guy in the pattern, on a cold but brilliant winter's day. The other guy kept on getting into my airspace so I started moving it away from him to another area. Made the classic mistake of flying it through the sun, momentarily blinding me. I had no idea where the plane was. I instinctively cut the power to idle and added up elevator, hoping I'd give it some more time to find it and land it. After awhile, I knew it had to have landed (crashed) but still wanted to harvest what I could like the receiver, engine, etc. But I had no idea where it was.

                                          An old man sitting and watching the whole thing yelled to me that he saw it, but it was far away. He suggested me taking my car to find it. Believe it or not, after driving out to where I thought it might have been from his comments and walking around for 10 minutes searching for it, I did finally find it. And it wasn't in pieces of wood like I suspected. It had landed itself, making some wheel tracks in the snow after it had apparently glided over some pine trees. I was amazed!

                                          I drove the plane back to the field to show the guys. They were amazed too, and I resumed flying it. What a day!
