Official Freewing Vulcan 70mm EDF Jet Thread

Does the ESC support thrust reverse? If so, how do I set it up?

[Quadflyer68]

The wings are so short on that F-104. No wonder it has to go really fast!
I'll stick with longer wings - for now ;)

[Quadflyer68]

Well, I hope I do as well with the Avanti as I'm doing with the Vulcan :)
Flight 2 the next day was just as good - got the landing on the first try so no go-around.

[Alphonso]

It can come in like a missile if you don't slow it down yes. But I wouldn't warn someone about that as it can also fly really slow. Bit like saying you can't park a corvette cos it's fast.

[Quadflyer68]

Thank you Danimataro :) I was surprised how well it slowed down and landed after reading a bunch of posts saying it comes in like a missile with wings lol.
I like this flying field a LOT. It's way better suited for EDF jet newbies like me. Let's hope the good vibes continue ...

So this was my 4th EDF jet maiden, and the best one by FAR. The jet performed great - it tolerated my flying skills (or lack there of) very well ;)

Went with the Liperior 6S 3300 40C. 3.5 min flight. 3.87V per cell after landing. Must have gotten the CG and pushrods right; it didn't need any trim (that I could tell).
Had rates set at 60/80/100 all with 35% expo. Took off with 60, later turned on the gyro (A:30 E:30 R:30) and felt the need to try 80 - much better.
The jet seemed pretty forgiving - I think I banked too sharp at least a couple of times, but with power so no stalls.
Very pleasantly surprised at how smooth and well behaved it flew.

Congratulations on your inaugural flight with the VULCAN, my friend! As I said, the VULCAN is a great airplane, well-built, with good electronics and good engine power. A very, very good landing again, my sincere congratulations! Now to continue enjoying this wonderful and "fast" airplane, which I'm sure will give you many good flying days. Today I lent my VULCAN to a friend at the club where I fly, and he liked it so much that he's already ordered it from MOTION RC, and he'll be getting another box with a blue tape with another VULCAN for him...

Greetings to all!!!

Okay, thanks guys. I'll just put a little tape over the end of that JST for now.

[Evan D]

Yes, some of the AB systems work on 12V. The FW one does. It has ground on the black wire at pin one and picks voltage off the third voltage wire which is the fourth pin on the battery connector.

The JST is to full battery voltage whatever that may be. If a 6S Vulcan it will be 25V full charged. I like the telemetry idea, it could be that too. The odd thing is the FW afterburner does not come with a JST to the Tailflame control board and if it did it would probably smoke on 25V, maybe it will in the future.

Most AB bulbs are 12v and connect via lipo balance port plug on an intermediate pin (#3 I think). That JST plug will deliver 6S voltage. Maybe in was installed to provide lipo voltage via telemetry.

In your post # 369 in this thread, the photo looks as if the JST is just a power takeoff from the LiPo connector. That suggests it's just an afterburner connector for the Freewing Tailflame afterburner, as Evan suggested.

Maybe an update. Mine doesn't have it and I don't remember anyone else saying they have it. I have to think for an afterburner.

[Quadflyer68]

Brand new plane and ESC from MotionRC.
I saw a video for the new Ares 90mm and that has it too.
(The video is not in English so I don't know what was said about the JST.)

At about 10:40 in the video

[Evan D]

Was this a used plane or ESC? The stock one doesn't have that. Maybe they installed a afterburner?

[Quadflyer68]

What is the JST connector in parallel to the mains for ?



Designed & printed a custom tail pipe.

[Quadflyer68]

Yep, those racing batteries sure are nice and lightweight, and expensive. Too pricey for me, at the moment.

[Evan D]

As I said… “Power Hobby 5000mAh batteries. They weigh 545 to 575g”

manufacturers change cells all the time. It’s why I always say if you like a specific battery buy a bunch as they may be different the next time you order.

[Quadflyer68]

65C. One is slightly heavier than the other. They must have changed something ...

[xviper]

5000s - 755g (798-800g must be the shipping weight). This is 100g lighter than my two 2700s with parallel cable.

What "C" did you buy? I'm charging a CNHL 5000mah, 65C, black label right now and it weighs 811g.
I used to fly my Vulcan with 5.0 Gens Ace that weighed 700g.

[Quadflyer68]

Nice! The CNHL 5000s and Liperior 3300s arrived today:

5000s - 755g (798-800g must be the shipping weight). This is 100g lighter than my two 2700s with parallel cable.
3300s - 505g (pretty much published weight of 495g).

Still waiting on the 4000s (slow boat from China). Hope there's no tariff surprise ...

[Quadflyer68]

Congratulations, buddy! That VULCAN looks so beautiful and looks so good! Now let's get it set up properly and enjoy it for a long time.

The assembly is truly a delight; it goes together very quickly and without any problems. In my case, I opted to forgo the little blue box (which isn't really there for anything other than replacing the Y-cables) and put everything together with Y-cables, all neatly organized, securely fastened with cable ties, and with their respective hooks so they don't come loose.


Here's a link to the video of my VULCAN's maiden flight at the club where I fly.That was a year and a half ago, with countless flights in between, and it's still flying as well as the first day. I'm very happy with this plane, and it's one of my favorites in my fleet.

Greetings to all!!!

Great maiden! Hope mine mimics yours and not some of my previous ones ;)

Yeah, the blue box is kind of awkward. Mine's hooked up for now, but I'm weird with wires and that bird's nest is not sitting well - lol.

Looks like that blue box has more functionality (flashing LEDs?) if the empty spaces for electronics are populated, and the 2-pin jumpers aren't cut.
