Whoosh to me mean means wasted ampsand lost thrust from turbulence...so the sound of the FMS is much better to me. For sure was better sounding in the F-104 too...
That's what makes this hobby so fun is all the opinions, just like these afterburner lights, I could care less about having one in my jet but other people get a kick out of them and try to out do one another. If my so called stock afterburner lights burn out on my F-16 or the F-104, I won't even bother replacing them.
It might help with the weight but no way does the FMS unit sound better, I had one in my F-15 and pulled it out and dropped in the FW 1680kv, now it has a nice woosh which is what I am into more than weight savings, the weight penalty is worth it so my F-16 has the new 1835kv in it now, I didn't really notice better flight times with the FMS unit but I did feel the weight savings.

Well, weight was always my primary issue with this model. I agree, if weight can be shaved using the FMS setup, I am all for it. I am sure the Freewing setup is good too, but for this model, weight saving is gold currency.
With my f-104 it helps with shifting the CG into a better part of the range. I believe that it may also do the same thing with this plane.

I agree with Gooniac. Like all planes, the lighter the better, especially in the F-16. If you keep the batteries light too it will be drastically improved.
I prefer 5000s (725g) and below. All my 5000s are HRB. With some of the hobbystar and roaring tops of late, you can go larger than 5k at probably less weight
I have yet to maiden mine but I installed a FMS1900kv 12b edf and was wondering how it compares to that new 1835 fw edf.
The 1835kv will win in top speed for sure. But that fan will not get as good of a flight time and the weight is considerably more than the FMS unit. With the FMS you will get a slight boost in speed over stock but the main benefit is lighter weight, increased efficiency and really good sound as well!
Somewhere along the way I have lost my subscription to this thread so I have re-subscribed...It's been several years since I had this jet. Love the size and scale appeal but never liked how heavy she was and flew stock. I have satisfied my large scale F-16 itch with the HSD 105mm F-16 in recent years, but she too, is a chunky monkey. However, having no idea when or if Freewing will be coming out with a New Gen 90mm F-16, I thought I would revisit this model, especially after seeing Jeff's (of Jeff's Custom RC on YouTube) fabulous job of converting his to the Arctic Camo (video below)...Now I want one again, and paint it up the same!
So before I sink my teeth through 20 pages I was hoping I could get the quick and dirty Upgrade/Mod Cheat Sheet...
I assume I will need to put a new power system in it. Looking for a great solution. Something that can help offset the AUW with the appropriate thrust to weight ratio. Looking forward to any and all information!
Thanks!
Aros, I found the perfect combination for this bird...here is a quote from my earlier post:

New 1835KV upgrade! I upgraded my F-16 from the stock edf to the new FW 6S 1835KV EDF. What a difference! The model came to life and the thrust to weight ratio is perfect. I was thinking of going to 8S but I am glad I did not - the 6S setup is lighter and this plane does not need any more wing loading.
I had to add 30g of weight in the nose and move the battery forward as far as it would go. The new FW inrunner is 107g heavier than the old outrunner. I highly recommend this upgrade and the EDF unit is a drop-in replacement with no foam cutting needed.
If anyone is looking for a bulleproof low cost upgrade for their esc let me share what has worked for me. The Red Brick 200amp from Hobby King has been an amazing unit and it costs less than $50!! I first tried one in my F-15 which actually did draw over 180amps on one set up... the unit too it with no issues even in high ambient temps. Never onces shut down due to over heating or anything... It is regularly running 150amps peak in my F-15 now and hasn't skipped a beat. Flew yesterday in 100 degree weather and it was perfect. I have that same unit in my Mig-21 which is kind of overkill but still for the money it never hurt to have the extra headroom. Its pulling less than 100 amps but still nice to have something that works so well. I just installed on in my new 90mm F-22 with my custom Leopard 4092 1730kv set up and freewing rotor and flew that in over 100degree heat yesterday with zero issues... Great units!! Super cheap, easy to program with card and just all around good...
I would be very careful keeping the stock ESC. I flew the F-16 with the FMS fan and stock ESC on low timing and had to make several emergency landings before realizing that I had an ESC problem. It acted normal for a few flights, then starting going into what seemed like an LVC cutoff mode mid flight. Replaced the stock ESC with a YEP 150A and it’s been a great flyer ever since. The FMS setup changed the airplane for me. The lighter weight actually allows you to glide it for a bit without dropping like a brick, and it has better vertical and flight time. It used to be a hangar queen with the older stock system, but it’s become one of my go-to edfs now.
It was your story that I was thinking of regarding the stock ESC.
I already have the same YEP 150a ready to go in the F-15. I figured that it had to be somewhat of an upgrade being as the F-16 and 15 were both heavy and the FMS was just what the F-16 needed. It’s by far the biggest upgrade I’ve done to a plane while staying the same cell count.
Anybody got a good Home Depot paint match for the stock colors? I'm going to do either the Lone Star or Wild Weasle livery but will need some touch up paint for cerrtain areas after I mask.
Oh, good to know about keeping the stock 130a an option. I had read previously that I guy fried his after the FMS swap, but in reality you never really know exactly what has been done to peoples planes and parts when they get on here to discuss.
Have you used the FMS in the F-15? I have 4 options for 6s, one being the FMS unit, the FW 9 blade 1750kv, 12b 1650kv outrunner, and it currently has the HET 1680 installed. I might as well sell the 1750... I purchased it the day it released in China, which was quite a while before it was available at motion. It’s never been flown
