Official Freewing 90mm F-16 V2 EDF Jet Thread

[lusek_pl]

I made my second and third flights. After analyzing various videos, I moved the batteries forward, and that was it! However, getting out of the grass with this model is terrifying and takes forever. I have to fly into it, and then I'll tell you more.

Thanx Hugh will report

[Hugh Wiedman]

Hey guys. 5 flights now.. overall happy.. first flight last weekend. Failed to get off the freshly cut damp grass.. so 8 s fan in place..
But after going back. In this thread
. I'm concerned about the weight. I only have HRB 6000.. Times 2 4s.. coming in at 550 grams times 2. Totally 1100.. this is what I fly my f4 on. And it's awsome..
But boy it feels heavy.... So I'm asking is anyone flying this on that weight.. any other thoughts

It looks great in the sky

Hey Mate, I'm flying all my 8S on either the SMC 8S HiV 5900 (970 gr) or even the SMC 8S HiV 4900 (841 gr). F4's and F16 on the 5900, F22/F18/EuroFIghter on the 4900. Don't think you can get the SMC's "Down Under" though. On the F16 V1, it doesn't seem to fly much different on the 4900 or 5900, both get off grass almost identically. Does make a difference on the Euro and F18's though.

Thanx viper I'm ok with an Xtra 88 grams

I fly mine on 2x4S SMC 5900mah HV weighing 1012g and on 2x4s Coddar 6000mah HV weighing 860g. They both seem to fly the same. Short cut grass no problem. Good power and "get up and go". It/s a little "heavy" but nothing alarming and not unlike my other 8s 90mm jets. Still can accelerate from slow speed to max speed easily. With air brakes open, lands high alpha very nicely and controllably. Reverse helps when landing on smooth runway as the plane's weight does keep it rolling. A friend has the 6s version and only flies it off the GeoTex runway, not the grass. All in all, a very satisfying experience.

Does sound heavy. Mine has a JetFan which is a little lighter than the current high power FW fan and I fly 800g of battery and it’s awesome.

Ding dong here figured it out.

I plugged the leads into the rx upside down.

Good grief.

The long lead has four wires, yellow reverse, white throttle signal, red power (BEC 5.5V out to run your radio system), black ground.

All current FW ESCs that have reverse function are this way. FW no longer has and PNP with separate except the twins, Mig29, F-14, etc.

If it doesn't have a yellow single wire plug it doesn't have reverse. Most FW PNP planes now have reverse but not all.

Xviper has a great trouble shooting list.

[xviper]

1. What Evan said. Don't plug that short lead into anything unless it's a programmer and you want to change the programming.
2. The constant beeping is saying the ESC is not initializing. Could mean:

a. Is the throttle trim minimized?
b. If you're using Spektrum SAFE/select RX, you may be too close. Step back about 5 - 10 feet when binding and when trying to initialize.
c. Throttle lead from ESC (or power lead from external BEC) not plugged into RX or wrong polarity).
d. Try throttle calibration.

[Aros]

The long lead is to the throttle and the reverse thrust branches off of that. I’ll check out the ESC manual. Thanks.

[Evan D]

The little lead is for the programmer. The power for your radio (BEC output) is over the long ESC lead. Look at the instruction for the ESC, it shows how the programmer hooks up.

[Aros]

Gents, I bought the ARF PLUS to replace my PNP that hit the dirt. Installing the power plant, I notice there’s a lead coming out of the ESC that is inexplicably like 1 inch long. Plugging everything in and binding, I am getting the usual beep every two seconds telling me the ESC is not arming.

I assume this weird little lead is the BEC you need to plug into an available port on the receiver. All good and well but how the hell can you plug a 1 inch lead into a receiver that is a foot away? Yes I get you need a foot extension but I don’t recall needing that extension when I removed it from the original PNP?

What am I missing here?

[f4u ausie]

My first flight was awsome factory mid throws. 50 percent xpo.. don't like dual rates.. HRB 6000 smack bang on CG marks.. and I found it landed very nice 👍. No flaperons. In fact slower than. My f4. It's 6s. It is heavyer than the 8s phantom. But to me flys easier

[lusek_pl]

Thanks for the replies. I fly the Typhoon and the Al-37 and the HRB handles well. The intakes open very quickly, about 30% throttle. Next flight, I'll increase the elevator deflection and move the batteries back 1 cm. I'm also considering adjusting the flaperons for landing.

[xviper]

I concur with what Evan said. This jet is heavy. The other jets that you use these HRBs in ............... are they as heavy? On 6s, I found I had to be in the upper part of the throttle almost all the time. I find those "air brakes" make a lot of difference, but only if you give them time to work ............ IE, have a longer approach to the runway so the speed can come down before it gets there. Failing this, you may consider flaperons.
As for the HRBs, I find them to be - "mid-tier" LiPos but that's depends on the "C" rating. The ones I use are 50C (more like 30C). They do make them in 100C but I can't get those easily. Again, are your cheater doors opening freely?

[Evan D]

The F-16's, both the original and V2 fly heavy, even on 8S. This plus a nose heavy plane caused your elevator authority to be weak. I suggest adding some elevator throw and checking how your plane is balance by flying inverted and seeing how much down elevator is needed to fly level.

[lusek_pl]

Some clarification ............................. Is this your first flight on this plane? Are you running 6s or 8s?
"plane would never land" ............................... Do you mean it was very floaty and didn't descend easily?
"poorly responsive to altitude" ....................... Do you mean it didn't seem to have good power on take off and climb? Are those spring loaded cheater holes easily opened upon high throttle application? Or are they stuck shut when taking off and climbing? When mine came out of the box, those cheater doors were stuck shut from the paint. I had to push them open to break the paint seal. If they are stuck shut, the plane will feel like it's only got 1/2 power.
"settings to low" ........................... what settings? Do you mean "low" rates?
"HRB" ..................... What "C" rating are those batteries. HRB's aren't real good for high draw applications unless you are running an 8S set up. Then the 8S power overcomes any deficiency in the LiPo's delivery. For 6S high draw applications, HRBs are not a consideration for me.
"Package is backward" ............................ Please explain. What do you mean by "backward"?

Yes, it was my first flight, using the 6S package. I fly several jets, and these packages provide plenty of power, so there's no problem with that. It reacted very slowly to the elevator; I had to deflect the entire stick. I have a 40-degree Expo. I meant low control deflection values. I flew on a windless day, and the plane didn't slow down at all, which is why it wouldn't land. In my opinion, airbrakes don't matter. Regarding the batteries, should I retract it to improve CG and elevator response? I hope I've made my experience with this model more specific. Regards.

[xviper]

I flew my Viper today. It was a crazy flight. I thought the plane would never land. It was sluggish and poorly responsive to altitude. I set the settings to low, as per the instructions. The HRB package is as pictured, and there's a lot of up-trimming. What should I improve? The package is backward?
