Elbee , hope you find a way. This ability with the Spektrum is by far worth its weight in gold, the single, most useful transmitter setting (OK, D/R, expo and throttle cut aren't bad either). I'm constantly refining the elevator and aileron trims (usually none or just a click) with almost every flight and every plane when deploying flaps. Seems like it even changes slightly as the day heats up from the early morning or when the winds pick up or shift. And as I continue to work on my landing techniques, the ability to adjust elevator trim in flight with the flaps fully extended has helped greatly. Takes all the guessing out and alleviates any extra stress, cause god knows, I got plenty of stress emanating from my poor flying techniques.

After losing several planes over the years including a Hangar 9 Miss America, a much loved H 9 Bluenose Mustang and a Freewing SU35 to undoubted brownouts with an eight channel Spektrum I binned it and bought a Taranis Plus 9. Other than a couple of fumble finger mishaps the Taranis has not missed a beat. Programming mixes is virtually unlimited, I'm running 12 channels on my SU 35 using about five mixes. I don't want to start a brand argument...just my experience of Spektrum.
Just received my edf for the F4 ....Freewing V2 6s 12 blade 1835kv... any of you chaps have experience or opinions on this in the F4 ??

Thanks for taking the time on the explanation. I am an oddball I fly with a Hitech Aurora 9 radio, have been for the last 8 years. Anyhow I have the plane setup per the manual on the throws with the elevator set at 8mm up trim in the neutral position. I have flap/elevator mix set per the manual as well.
I did get the double burner installed and I am working on installing the aluminum tape now.
I just need to pick up a small 2S battery to hook up the burner.
Later!!

Thanks in advance,

Maybe a better explanation of what I said earlier is that the flaps create lift, but at the aft portion of the wing only causing the leading edge to go down, resulting in a need for up elevator trim. Commercial jets, and the FW T-45 also have slats on the leading edge of the wings. This also creates lift, but at the leading edge. So with flaps and slats, the entire wing experiences lift and I would suspect (don't have a T-45 though) that those jet would take some down elevator to maintain level flight. The B-24's wing on the other hand is relatively narrow and towards the front of the plane, so that the lift generated by the flaps is dispersed to the forward section of the plane resulting in the need for some down elevator. The tail section is relatively further back allowing the elevator to get uninterrupted air flow as well.
As I stated earlier, with flaps deployed for take-off on my F-4's, to maintain level flight requires the servo travel on the elevator to -20 (starting at 0 for flaps up) and -25 for landing flaps (this is actual servo travel, not trim numbers or % compensation in the Flap System).Hugh "Wildman" Wiedman

I have 35 yrs. in the hobby and most of it in prop driven giant scale warbirds and aerobatic planes...just starting with these EDF jets and the learning curve seems somewhat different. Forgive my ignorance but I don't understand your comments on "servo travel on the elevator to -20 (starting at 0 for flaps up) and -25 for landing flaps". I understand servo travel in % of deflection or degrees. Do you mean "-20" equaling -20 degrees; or 20%??
Thanks again ,

billd3 My mind definitely works in mysterious ways, even I can't figure out what I meant in describing the numbers I gave you on servo travel 2 posts above.
Hopefully, this makes more sense: The 0/-20/-25 values I gave on elevator servo travel with flaps comes directly off of the Servo Setup screen which shows exactly how the servos are moving and by how much. I did not want to give you the % numbers from the Flap System setup, because that's only a part of the story. The values I have there where only my first guess % numbers based upon others numbers and the manual. I use F Mode set up for ailerons and flaps tied to the flap switch so I can adjust both surfaces in flight with each flap position. In some positions, I may have say a -8% on the flap system, but I have +4. or say -12 on the trim monitor on the main flight screen. One position I have -18%, and -32 in the trim setting. By just giving you the exact amount the servo travels for each flap position, it balances any + or - I've adjusted in the trim offsetting or adding to the % programmed into the Flap System.
Now I hope were all confused Let's have another drink and go flying!!Hugh "Wildman" Wiedman

Elbee I did finish up the nomenclature on the F-4. A big thanks goes out to you for the info provided. I wound up not putting very much of it on. It got to a point where I really liked the look and was afraid more would have been too much.
I then sprayed 3 coats of satin Polycrylic through a new touch up gun I bought. I am really impressed with the gun and will use it to paint my F-18.
Anyhow today was the best weather day we had in over a week. I took my jets out for a group photo. Can’t wait to get these guys out to the flying field.
Later!!

Those are my homemade decals. Resized some images downloaded from the internet and printed them with my laser printer on white water slide decals paper.
I make my own decals. I still use Callie occasionally but she’s a little behind now. Decals will be a combination of water slides and vinyl cut outs off of my vinyl cutter.
The 3D files were downloaded from Thingiverse.com. It’s not my design but the files are fantastic and they fit perfectly.
