Official Freewing 70mm F-16C Falcon V2 Thread

[dahawk]

In the process of rehabbing my F-16.Sorting through the thread.

Anyone program Flapperons? I’d like to use a 3 way switch on the Dx9 . 1st position- Flapperons . Middle position- Neutral. 3rd position- Spoilers. Possible?

[rifleman_btx]

Right on! I really like that setup, and it just looks so cool I gotta get one at least

I can't answer for the F-86, as I don't have one, but the F-16 is a great flying bird. If you're flying from a fairly smooth surface, the 4500mah batts should be fine. I fly from grass, with a 4000mah pack. I also have the upgrade gear, and they help smooth things out. Flight times are decent if you back off the throttle some. The F-16 was my 2nd EDF and had no problem flying it comfortably. A clubmate flys large turbine F-16s and coached me on keeping a high aplha approach and landing. That's the ticket.

[rifleman_btx]

Heck I may just get both. Lol

[rifleman_btx]

Well I'm looking at either getting this or the 80mm F86 for my second edf. I'm planning on sticking with my 4500mah packs. Just liked how both jets perform.

Hi, I'd like to know the battery tray dimensions. I wonder if I can fit a 4000mah 6S battery with these dimensions: 52X51X146mm. Thanks.

Battery tray dimensions are 77mm wide. 200 plus long, more like 220 when using all of the space to the rear of the cockpit, and the height at it's shortest where the battery could side to the rear of the fuse for balancing is 46-47mm, so you are good on two dimensions. It will depend on the battery weight if it will work...The Admiral Pro 4000 is 50 x 42 x 142mm... So it is smaller than your battery described... Hope that helps.

[rifleman_btx]

That should be nice!

I've started working on the F-16 again. Haven't crashed it but it just didn't fly very well.the first few outings. . Think she was too cluttered up blocking air flow to the fan So, she's been a hangar queen for about a year. Changing out the power to a 6S Dr. Mad Thrust 11b 1900kv setup: https://hobbyking.com/en_us/dr-mad-t...00watt-6s.html

Should be enough power right ? watts and thrust ?

Specs:
EDF Inner Diameter: 70mm
Outer Diameter: 72mm
Construction: Alloy
Weight: 230g
Max RPM: 46000
Motor Type: B2850 1900kv
Max Power: 1900W
Continuous Power: 1700W
Max Voltage: 22.2V (6S)
Max Amps: 74A
Max Thrust: 2.1kg

I fly mine with a Admiral 4000 Pro 6S and it fits fine with room to spare. Welcome to the Squawk!

Nicely done. Great vid!

My First test f-16

[Ted7rns]

As mentioned above it may be hard to get it to rotate off of grass. But on a paved runway I have had no issues at all with even the heaviest packs that I have. I am stuck on a 6s 35c 5800mah pack which is light for its size but heavier than the 4000s. The plane required just a lil bit of up trim but didn't fly much different. Just barely longer take off and roll out. If you are flying from a paved runway the 5000s will work just fine.

That's great. I'll buy it this week then. Thank you.

[gooniac33]

Okay I have read through all 34 pages, and I think I'm more confused then ever... lol.

I have Roaring Top 5000mAh 45c batteries 755g..... will they work? Or is it too nose heavy?

thanks for the help.

Okay.

I have an Asphalt Runway.

Take off distance, you should be OK. You asked if it will be nose heavy. Why don't you just put one of those batteries in and see if it'll balance at the CG.

I fly mine with a 4000mah Admiral weighing in at 600g. When I used a 5000mah, it wouldn't get off the ground. I fly off rough grass and it would not rotate in the distance available to me.

There was no wind at our field today. I obtained some interesting info: my GPS is telling me that a high alpha pass (30 to 40 deg angle of attack) using thrust to hold altitude is at 20 mph (sometimes 19 or 18)!!! It sure looks slow and majestic. Yet plenty of power to accelerate vertical from a slow pass like that.

Completely stable with full UP elevator, pretty amazing. I’ve mixed additional UP on a switch for assisting in landing, touches down on the mains and tail cone. Awesome plane! Still rolls a long way, got to tighten up the axles a little bit.....

Nothing cooler than a super slow high alpha pass just inches off the deck and seeing the dust blow away as you travel down the runway. It is one of my fave things to do!!! Mine is a lil heavier so I was able to get a 23mph High Alpha pass with no wind. With wind the passes were at barely 13mph ground speed....
