CVA59, the way I understand it, you should lengthen the 'motor' leads rather than the ESC leads and add some suppression in the form of ceramic rings It becomes an issue of 'electrical' interference the way I read it. Again, this is what I have read, not something I have had to deal with in the actual. Best, LB

Yeah don't worry about it. You are not adding excessive length. But be aware that the F-86 was one of FW first EDFs and the motor/ fan in that made quite a bit less than the stock A-4 unit. The F-86 unit in mine made 1624W and the A-4 made 2124W, over 30% more.

I need to lengthen the EC5 connector wires, ESC wires (red/black). My initial thoughts were to simply make an extension. Would this work?

If you don't know the Buck Danny pilot comics series I can highly recommend them, don't know if they're available outside Europe.
And btw, drop the sir thing please, I'm only half way my time at earth so I'm not ready yet to be called sir haha

About the motor:
The former stock motor in the Skyhawk is a 1800kv outrunner with a 12b fan in a metal housing if I'm not wrong. Had that motor in my Mig-21.
I recently installed an FMS 2100kv inrunner with a 12b fan in a plastic housing (pro version) and the acceleration on the ground was A LOT better, faster in the air as well of course.
I have the Freewing 1857kv inrunner with a 12b fan in a metal housing in my L-39 and love it also! Can do 8,5minutes flights on a 6000mAh lipo if I'm just cruising around.https://www.rcgroups.com/forums/member.php?u=559880
On my blog on rcgroups I have an article with some static ground tests and comparisons I did between the FMS & Freewing setups, if you're interested you can find it here: https://www.rcgroups.com/forums/member.php?u=559880
Bottom line of the story: you can't go wrong with the FMS or FW inrunners!

Rich / Icarus...............Thank you for the great info! Yes, I will more than likely upgrade at some point. However, at the moment, my biggest objective is to determine if this F-86 setup will fly the A4 sufficiently based solely on the data. This F-86 setup I have is an In-runner with a 12 blade fan. I'm hoping to get some use out of it while learning the flying characteristics of the A4 before putting too much speed into it. Once I get a good handle on flying the A4, I will more than likely jump up to something more powerful. I will be using 6S, 4500's & 5000 packs with this setup.

My A-4 came with a 1850kV motor. I realize different markets got different options but if you got it from Motion it had a 1850 in it. The older Mig had a 1800kV in it. The first L-39s had the A-4's 1850 but later camo ones got the 1857kV.
The newest 80mm system is a 9b with a 1920kV and is what comes in the T-33. I like this set up. The A-4's 1850 is my favorite 12b set up.

Can you guys also show me where the nose gear retract servo lead plugs into the control panel board?
You'll see the nose gear retract wire Is plugged into the board at the top right position of this picture. Look very closely and see that the little diagram printed on the box is marked "gear" for that position.
The white wires on the top and bottom are the cables from the wings.
I found the throws were way too sensitive for my liking, so I reduced it. On my radio, I've reduced the control throw to 54% on aileron and 67% on elevator.
I am also using 45% expo on aileron and 38% on elevator. This is what I did, but its really a matter of your preference and flying style. I like flying smoothly and scale-like, at least I try to do that. This model will roll like a g-d drill bit - it rolls so fast that you can actually induce a stall at high speed. (Mine starts to snap-roll after about 2 high-speed rolls) Where I have it set now, it rolls very quickly but nicely and the expo allows me to be smooth. So that's just me, you'll need to find what works best for you.
Marc flies FW & FL: AL37, MiG-29, T45,F4, A4, A10, F104 70 and 90, P38, Dauntless SBD, Corsair, B17, B24, B26 & P61, Lipp.P19, ME262, Komets, Vampire, SeaVixen, FMS Tigercat, FOX Glider & Radian XL.

Got it, works perfectly now, thanks
I will also use your settings to start with. I am a scale flyer as well.

Well, after several weeks of repairs, paint and Callie graphics, here she is ready to fly again. Still have to get the CG correct and setup the control throws but otherwise she's all set. I did her up in the VA-46 "Clansmen" squadron that was aboard the USS Forrestal on July 29th 1967 when it caught fire. One of the pilots who was strapped in awaiting launch while sitting tip to tip to John McCain that day is my friend, Dave Dollarhide. I have used Dave's photos and such to replicate the plane he was flying that day. Dave was very impressed that I chose to replicate his A4 for my R/C version. Dave has an incredible story for those who have an interest. I have attached the PDF of Dave's story to this post as well. There is also a video of Dave's last flight in the A4.
