This was tested in the plane. Not a true measurement since I only have acces to a kitchen scale and I only wanted to see what the fms put out. I’m going to try the original hp version fan. I’m just disappointed in the performance in this f15. She seems to drag it’s butt all day long, while my f14, l39, Avanti, 70mmf18, f16 move in a more authoritative way. If that makes sense.

Now this video is not the F-15 but my other friend uses the same set up that is in this F-4 in his F-15 and it made it a rocket ship. He ca get 5 min flights with throttle management but it still flies jet like at lower settings!!

Just got a ARF Plus of the F-15 which I installed the new 9 blade FW fan from the F-4. I have watched the build and flight review, but they did not talk about elevator to flap mix. The F-16 needs up trim as nose pitches down with flaperons, and the F-4 needs up elevator as well. So what does the F-15 need when flaps are deployed ?? Thanks for input

I don't use any mix on mine, sure others do but mine is fine with full flaps, I even pop the speed brake out on final and add a little power for the extra drag, the F-15 is one of the best ones on landings. I'm curious how the 9 blade works in yours, I tried it and it wasn't much better than stock so I went with the 4068-1680kv and that works very well. Let me know how it goes.

I like the sound of the 4068-1680kv is my problem, it has a nice woosh that sounds good to my ears for some reason, I like sound better than performance so that is why I went with the 4068-1680 in all my 90mm jets, didn't care for the whine of the 9 blade, but I gained both so I'm happy with the upgrade. Hope you like the 9 blade, it will fly the F-15, watch your timer because when I had the stock F-4 Phantom I was only able to get 2 1/2 minutes and that was it on a 5000 60C battery, don't know how others were getting 3 minutes, flight times were no better when I tried it in the F-15.

The reason I put it in was it has a lower amp draw then the inrunner, which I hope might be easier on my lipos. This is the same fan used in the new Raptor, which if you go by advertised weight is very close to the F-15 and also the F-4. I'm not sure why the Raptor was pushed as lighter then the F-4, but when I get mine we will see, where they all come in on weight. I have watched the video of both the F--22 and F-4 and for my flying style and comfort zone,, they fly plenty fast. I don't have a super large area to fly out of our bounds of our club field, as I see in some of the videos. Many of you guys are lucky to have such huge fly over areas where you can wring out these jets to the max. It is the beginning of the crap weather here in upstate NY, so I don't think I will get it out to try to spring.

I got a flight this past weekend with the Hobby Star 6s 50c 6200mah pack and man was it a blast! My plane is modded but usually gets 3 mins flat... no time to spare... I flew really hard and would have normally depleted my pack. Landed with 3.65v per cell... I may have a new fave F-15 pack....Check me out on youtube at https://www.youtube.com/user/gooniac33
