Official Freewing Vulcan 70mm EDF Jet Thread

[Quadflyer68]

Okay - just ordered two 6S 4000mah 65Cs for the Vulcan, and two 6S 5000 65Cs for the Avanti.
I'll see how I like them and then decide what other sizes to get :)

When I was planning the Avanti purchase and what Lipos to use (2x 2700s in parallel), I didn't consider their combined weight - DOH!

[Evan D]

I agree. The recommended battery is 624g which I feel is heavy for this plane.

Hello!!!! That's one of the things that surprised me most about this plane: not having to detach any servos from the foam to replace them if necessary. I think the servo attachment system with the plastic plates is a real success on FREEWING's part. As is the wire it comes with to run all the servo wiring from the tail assembly to the nose of the plane, to connect them to the receiver. These are small details that make the difference to me. The issue of the size and weight of the batteries: moving outside the recommended weights will mean the plane will need more speed to fly and will be heavier. Therefore, when it comes to landing, it will do so with more speed and inertia due to the extra weight and will glide less, nothing that can't be solved with proper use of the flaps and reverse thrust upon landing.

Greetings to all!!!

Hey! I really like that I won't have to dig glued servos out of foam if they need to be replaced :)

I use Power Hobby 5000mAh batteries. They weigh 545 to 575g, the older ones were lighter weight. I have a dozen of them I fly in many planes and really like them but they are expensive, $120 but they have a military discount. If I was buying today I'd get SMCs, they seem to be good batteries for the money.

I get 6-7 minutes on the 5000's.

I saw this video where he flew the Vulcan with a 6S 6700mah battery - that’s gotta be big and heavy:

I didn’t see the battery compartment dimensions in the user manual.
The 6700 pack is 54mm x 50mm x 150mm and weighs 835g.
Two of my 2700s are 72mm x 45mm x 150mm and weigh 860g.
Guess I’ll do a fit test when it arrives, side by side, stacked, neither …

What size lipos (6S) do you guys use, and how long are the flight times?
I'm looking for 3 to 3.5 minutes, minimum, with enough left over for a go-around or two.
Are 3300s worth it at all ? I have some old Century helis that take 3300s ... ;)

Thanks again!

I’m the guy using two 6S 2700s in parallel in the Avanti. Have to stack them to be able to push them all the way back. Total weight for both batts and parallel cable is 860g. Probably too heavy for the Vulcan I’m thinking.

Up till now I’ve been trying to minimize acquiring too many different sizes of lipos. The 64mm jets both take one 2700 and the Avanti takes two ;) However, I’ve decided “Screw it - life’s too short. Get the damn batteries lol “

Not gonna lie, the Avanti still kinda scares me. Probably should have gone the Vulcan route first.

Hello!!! I use two 2600mAh 6s batteries in parallel in an FMS FUTURA V3, and if you keep the battery position in mind so the center of gravity is in the right place, there's no major problem. I also have an FMS FUTURA in the 4s version with a 64mm EDF and an EFLITE VIPER, also in the 4s version with a 64mm EDF. I've used two 1500mAh 4s batteries in parallel in both, and they fly equally well. I just need to move the batteries back a bit to keep the center of gravity in the right place in both planes.

Keep it up, you'll see that the VULCAN is a very good airplane. It's very well designed, and the engines, both 4s and 6s, are more than adequate for the weight and size of the plane.

Greetings to all!!!

Definitely. Although only about 30 in this hangar so far (helis, planes, FPV quad copters, now EDF jets). Batteries already out of control - One more smoke stack isn't gonna pollute the world, right? (err, maybe not the best analogy)

Yes, a pile of chargers too. Have settled into mostly using old iChargers - two 106B+s, and one 206B. Had to replace the tact switches on the PCBs. Lots of parallel charge cables too. Two 350W power supplies.

We all put up a valiant effort in that regard. I tried for the first few years but as the planes kept coming and going, I came to the realization that minimizing my batteries was a lost cause. I'm guesstimating now that over 250 planes and choppers have gone thru the hanger (of which I still fly about 50+). My batteries are in 3 large fire resistant safes and one large battery charging box - all about 2 cu. ft, all quite full except for the charging box, which is used for storage of regularly used LiPos. BTW, you may arrive at at time when you start collecting chargers, too. I have 3 twin chargers, sometimes all of them on the go at once.
My old Avanti was a very nice flying plane, but it and the one my friend had, had very weak nose nose steering mechanism. Drove on the ground like a drunken sailor. IMO, the Avanti flew about the same as the Vulcan 70mm, maybe a bit more spritely.

The Vulcan has a pretty good size battery area. What are you using in the Avanti? They may work.

[Quadflyer68]

Thanks guys ! Will need to get some proper lipos too. Unless I can cram two 6S 2700s in parallel but I’m thinking probably not.

This is my 4th EDF: Viper 64mm, L-39 64mm, Avanti 80mm, and Vulcan 70mm. Found a ‘proper’ flying field so I’m hoping to be crashing mush less ;)

[Evan D]

Yes, still the Vulcan thread :)

Okay then, hope this is still the Vulcan thread …

I just ordered one. Along with a 10ch Rx. Looking forward to the maiden if the weather ever stops sucking.

Of course, it's still the VULCAN thread. You've made a great purchase, my friend. You'll see how this aircraft will give you many great flights. We look forward to photos when you have it ready for its maiden flight, and of course, a video too. I hope you enjoy it for a long time, and you know, if you have any questions, we're here to help in any way we can.

Healy's First law of Holes: "when you find yourself in a hole, stop digging".

You are not making a very good impression here.

I'm not in any hole, but thanks for your opinion and advice.

Have a nice day!!

[Evan D]

Again arrogance that you presume to know my feelings. Think what you like but, and this is not an opinion, you are wrong.

Why continue? After saying you won’t?

Now I think you are just trolling.

[danimataro]

I didn't lose my temper :)

Well, I think the opposite. I think you lost your temper in the message I quoted you above. But please, let's not start another debate about whether or not you lost your temper.... I don't want to, especially with you. I wish you all the best, and goodbye.

On the flip side both Xviper and myself have helped a very large number of people while in these threads. I even suggested how to slow down your retracts a year ago in your very first posts.

I hope you do remain in the threads and help people when they have questions.

And why wouldn't I help anyone who needs it on this forum? The fact that I don't want to know anything about you and xviper has nothing to do with the rest of the users. Of course, I'll stay on this forum and help anyone who needs it however I can

No problem, I'll tell you the same thing. Don't count with me for anything at all. At least we've agreed on one thing: ignoring each other.


See you never friend!!!

[Evan D]

Well, that's very easy on your part; you wouldn't have continued commenting after that message. I don't blame you because everyone is free to express their opinion, but always with respect. And you lost your temper with this message: "Having to say your peanut gallery thinks it's fast doesn't mean a thing. They probably just feel sorry for you." I think that after that message of yours disrespecting me, I should have ignored you. But since I'm a very clear and transparent person who likes to debate, I kept responding. A huge mistake on my part, and I recognize it. This ends my debate with you, now and forever.



May life go well for you, my friend!!!
