Official Freewing 70mm F-16C Falcon V2 Thread

Check out my flights from this last weekend. I was putting on shows with it every flight!!

How far back are you putting your 3300's ?

Not far at all... My 510g TP 3300s we just flush with the back of the canopy edge, but I had a slightly lighter power system in mine so that could vary a bit.

[Felixs10]

Yeah, it could use a little more aft CG I'd bet... However, the F-16 has always had a pretty wicked turn in without quite a bit of opposite rudder in the turns (The most aggressive I've seen IME)

A nose heavy CG would definitely make it worse along with a higher wing loading.

But keeping this plane as light as possible definitely makes a big difference in it's flight character.

I went back down to 3700mAh and it's much better than my 5000 setup IMHO.

After tying multiple setups... I'd honestly recommend staying with the stock 2300 setup with a good 3300 mAh pack. Can't beat it for the money!

Thanks Gooniac ! I'm going to try going moving the battery back . I do have a severely noticeable drop that needs tons of opposite rudder to correct. I was wondering if I should play with the C/G . I will move the battery back in 1/4 increments and see what happens .

My batteries are almost all the way back. Just the very front is being held by the strap. And that goes for any pack that I use in the plane. 4000, 4500, 5000 or 5800. All in the same place.

Thanks Again .. My 4500's are about mid- 3/4 of the way back . But to be fair I have brakes on this one which brings the C/G back anyway . We fly off a 250' runway and without brakes it needs just about all of it to stop .. I will move the LIPO back this Sat..

You are possibly flying nose heavy. You want the nose to drop a little bit but not just plunge down to the ground at anything beyond 45 degrees. I use a huge 6s 35c 5800mah pack and the plane doesn't dive like crazy when banked.

You need to use opposite rudder to keep altitude... 101 flying bud.

Bank and yank doesn't cut it.

Opposite rudder? Can you explain the why behind that?

[gooniac33]

Quick question, is it just me or does this plane loose lots of altitude while in a bank turning ? I'm c/ged correctly and the glide slope is incredible , just can't make a turn without losing LOTS of altitude. Anyone else having this problem ?

Thanks Alpha , I get it .. I have been flying for many years and I do use opposite rudder in turns , I guess I wasn't clear in my original post on just how much effort the V2 -F16 needs to make coordinated turns. I wouldn't expect it so much from this model , the star fighter yes , this one no . I was wondering if I missed something .

Excellent work! Very sharp, well done!

[Prowler901]

That's a beautiful job! :Cool: I'd like to get one of these someday.

So I have my new F-16 assembled, painted and pretty much ready to go. Just a couple finishing touches. Hoping to maiden it Sunday.

I don't think it shows up in the picture, but the pilot's name is actually a friend of mine that just retired from Lockheed Martin.

[Alpha10]

I agree. F-16 fly's " just okay" Thought she would be faster than she is but my Yak-130 with the same xrp 2200kv 14b combo &125 amp esc will pass her like she's standing still. Was surprised as the Yak has such a fat belly and the F-16 , a more sleek airframe. Might have something to do with the air intake on the F-16/ Very constricted IMO.

Absolutely... thrust gram for gram... The Yak performs MUCH better.

I actually scaled back my F-16 setup for a moderate one to get more flight time because the extra power didn't really net much over stock.

Granted, it was faster, but NOTHING like the gains I saw from stepping up my Yak.

Thanks for the input. I thought that would be the case. I bought the 6 cell version and am trying to "ease" into all the power it will have. Time to buck up I guess!

The 6s version isn't crazy powerful... It flies well and is VERY easy to manage.

Easier than the 4s version which requires much more throttle to fly. Plus, the heavier weight of the 6s setup also makes it track better and with more resilience to wind buffering etc.

6s is the way to go for 95% of fliers.

Again, this plane is not "Fast"... It just flies well and has a nicely balanced power system out of the box.

As a follow up to Dan's comment...........that was the 4S version of the 70mm F-16 V2.
Freewing makes them in two flavors.
4S - https://www.motionrc.com/collections...mm-edf-jet-pnp
6S - https://www.motionrc.com/collections...mm-edf-jet-pnp
But the 6S version will most likely not fly on 4S power going back to runway14left question;)
