Official Freewing 90mm Eurofighter Typhoon EDF Jet Thread

[Woohoo\o/]

It’s been a looong time and I’m finally ready to get me a new jet. I’ve owned nearly all freewing jets including the ef2000 when it was made of eps I flew the foam off of it literally chipped away. Im happy to see its epo now.

im going to ask a question that may trigger some people but do any of you fly this jet with the canards non functional? I ask because that’s how I flew the eps version years ago and it flew so amazing. Why would I want to do that? Well I’ve seen what happens to one when only one canard was operational and it was a nightmare. It snowed in Florida that day. Jokes aside I plan to fly it this time with the canards functioning except id like then only to work as pitch not roll.

i currently have a 6ch radio so I have to go without the air brake or reverse thrust. Which one should I go for? (I plan to get a 10ch radio soon)

thanks ahead and it’s great to be back. :)

I really like the airbrake, it really stabilized the plane on approach. I don’t use gyros. I think if you use a gyro I’d go for reverse.

Welcome back, does your 6ch radio have any type of mixing capabilities at all? I also had the old version and didn't have enough channels at the time to run pitch only on the canards so I figured out a way to do it but it required me to change out one of the canard servos to a reverse servo of the same type, if you don't change the servo you will get roll only, then you plug the canard servos into a Y harness and plug that into channel 6 on your rx and mix that with your elevator channel on your radio, you need the canards on a separate channel so you can reverse them if needed, they have to move opposite of the elevators don't forget, you can plug your BEC power into any channel with a Y harness, worked for me for many flights but only if your 6 ch radio can mix channels. If your radio can't do any of that I would just wait until you got a new radio with more channels so you can have all the goodies that the new Eurofighter has, it flies awesome.

Thanks for this info. This is what I needed. And yes my radio does have mixing. It’s a flysky fsi6x and also I discovered it actually has 10 channels. It’s the same radio I’ve used in my old ef2000. Thanks for the info dcorsair. I’m a huge Corsair nut myself. Waiting for DCS to release their module (digital combat simulator) also, did you see that guy who built a mini Corsair? I believe it’s called “war Corsair” he maidened a couple weeks ago. Amazing.

Yes I love Corsairs as well and its kind of how I got my DCORSAIR name, back in the days that was about all I flew and have built and flown many sizes of the Corsair over my 40yrs of flying, my favorite was my old big Byron F4U Skyboss Corsair with a big Saito 450 radial on it, what a joy to fly that was back in the days, I'm also following that 1/2 scale Corsair project that guy Don is building and I did see the maiden flight, awesome project he is doing on his channel.

So anyway you should be good then with the radio your using and with a little mixing should be able to fly the Eurofighter with pitch only on the canards like I did.

Yeah I think I’ll go for the air brake as well. I’ve used gyros on all my freewing jets years ago. It was quite nice but the way I see this bird flies I don’t think it’s necessary at all. Thanks Evan.

Plane ordered. Getting the ef2000 now and the twin 80 hog for Xmas.

I have a battery question. I own 4 zeee 5200 3s 80c with EC5 connectors on them. I’d like to make use of them. Will these fit in the euro? Motion recommends the admiral 6000 6s and the it’s heavier than two of my zeee’s together. I’m just concerned about fitment. How tight is it in the battery compartment?

That might be a problem. You've basically got 50mm of height and 70mm of width to work with, with length not being a problem. So guessing you'd stack them with height at 47mm, width 74mm. Tight fit. Why are the Zee cells so thick. My Euro is 8S and I use a 8S SMC HiV 4400 pack weighing 780 gr (58X45X140) Their 8S 5900 HiV pack is still only 935 gr and fits at 58X48X145 and blows the actual C of the Admiral and Zee Pack out (which is no where near 80C). If my Euro was a 6S, I'd use what I now exclusively use for all my other 6S EDF's which is the SMC 6S HiV 5900 pack at 740 gr and 47X50X150. Much smaller and lighter than the Admirals or your 2 Zee packs and definitely a higher true C and power rating. SMC packs are now the Gold Standard for weight and actual discharge levels (C). That 5900 V2 HiV pack has each cell at a .9-1.1 mohm Internal Resistance (which is directly related to actual C, the lower the IR, the higher the true C-don't be fooled by manufacturers labeled C). Most individual cells of other brands have IR's in the 2-7 range. The SMC's are Cheaper too and his customer service is unparalleled! You can compare on RC Groups thread all the information with virtually ever pack rated with statistics by an independent dude, MCS Guy. I have no affiliation with SMC, other than to say Danny's packs are now the absolute #1 packs for power, weight and price. Sorry if I sound like a SMC groupie, but they are just that good and most of those tuned into lipo packs are as well.

[Evan D]

My 6+2 is 73mm wide so I think that's okay but those are car batteries and, in general, car batteries do not have anywhere near the C on their label. I would do a very good ground test before committing them to the air.

[Woohoo\o/]

I’m just gonna grab a new set of batteries for the euro lol yes these are car batteries. I was using them on an arrma Mojave 1/7 6s and my miss geico 36 twin. They held up rather well. The reason why they are big is that they are hard cased.


im seeing a lot of cg placement on this airframe. Is there a one size fits all? Manual is legit?

[Evan D]

Better plan getting better batteries, there a lot of choices and though I don't use SMC or HV ones, what Hugh is recommending are very good. The CG marks under the wing, the manuals spot is very nose heavy. 20-25mm back rearward from there is a much better spot. There are some people even further aft but they also use gyros to help with it that far aft. I recommend starting about 10-15mm behind the marks for your maiden and move from there.

I have the same radio, FSi6X with 10 channels. iA10B rx. There are only 3 mixes available. I have replaced the VRA switch with a 3 position switch which I use to control gyro. You can use VRB switch for master gain adjustment if you wish or replace it with a 2 way switch for throttle reverse. Starting from left to right looking at the tx I have assigned switches as follows. switch 1 gear, switch 2 flaps, switch 3 gyro, switch 4 gyro gains., switch 5 dual rates, switch 6 throttle cut. I use the Hobby Eagle A3 super 4 https://www.youtube.com/watch?v=PWuGK8tU4AE&t=9s. It has 2 elevator and 2 aileron slots and allows you to change servo direction ( buy and use the programme card) and adjust the gains on each channel. Select flying wing/delta wing in the programme for Eurofighter. I do not have the Eurofighter but I use this radio and gyro on my SU35 and will be using it on my Mig 29. You may have to reposition some of the switch to board wire connections to suit your own desired switch positions. Using the A3 super4 will enable you to do some mixing and still leave the 3 FSi6x mixes available which may be required on some models. to give you an idea of what is possible see below.

Current setup of SU35 with Flysky FSi6X tx, IA10B pwm rx and Hobby Eagle A3 super 4 gyro using programme card designated as flying wing.
Channel 1 Left taileron servo (aileron in radio tx)Y`d to left (up/down )vt servo to gyro out 1
Channel 2 Right taileron servo (elevator in radio tx) Y`d to right (up/down)vt servo to gyro out 2
Channel 3 Throttle/motor( throttle in radio tx )
Channel 4 rudder servos( rudder in radio tx) Y`d to central left to right vt servo to gyro out 3
Channel 5 Landing gear ( assigned to switch 1 on my tx)
Channel 6 Flaps( assigned to switch 2 on my tx). Currently no flaps with SU35 but will be required for my Mig29
Channel 7 Gyro main gain to roll dial on tx ( assigned to switch 4 on my tx) Vrb on pcb
Channel 8 gyro on/off/autobalance lead( flight mode lead )connected to serial/RX/M port on gyro(assigned to switch 3 on my tx)
Channel 9 left main wing aileron servo to gyro out 4 (set as ail in programme card) No switch assigned
Channel 10 right main wing aileron servo to gyro out 5 (set as ail in programme card) No switch assigned
B/YCC Bindport on rx takes power in from external BEC.
Gyro A E R port with supplied 3 way lead (yellow, red, brown leads) to Ch1,2, 4 slots respectively on the receiver.
Gyro A2- E2- G port with supplied 3 way lead (yellow, red, brown leads) to Ch 9,10, 7 slots respectively on the receiver.
To get ailerons to work with tailerons
mix 1 is master ch1 slave ch 9, pos mix 70% neg mix 70% offset 0%
Mix 2 is Master ch5 slave ch 2 . pos mix -2% neg mix -2% offset +1% to give down elev trim when gear is down .
Mix 3 is off.

Without vt just ignore the Y lead setup

Have fun

The Eurofighter also has canards.

[paulrkytek]

The Eurofighter also has canards.

Yes. I was thinking that with 10 channels available and the super 4 gyro and swapping the 2 roll dial switches on the Flysky FSi6x tx for 2 and 3 position switches then the radio will have enough switches to operate a gyro, airbrake , throttle reverse, link the canards etc. If I can get taileron and ailerons working together on this setup it should be possible to do the eurofighter assuming the Canards are on separate servo leads. I am curious because the Eurofighter is on my to buy list for next season. Going back to my SU35 setup if I have mix 3 on my tx as master ch2, slave ch 10 it should give me elevator to canard mix but the only way to be sure is get a rx, gyro and a few spare servos and set it up on the bench . 🤔

The current Eurofighter doesn't have TV's so you'll be able to use the TV channels in your set up for them. If you can find the older V1/2 with TV you'd need the extra channels.

[Woohoo\o/]

I don’t have the eagle super. I have the eagle lite A3L. Would this suffice for the euro? Also would a 3300 mah 6s be okay or is it too little? I know I will have little flight time but it’s what I can use for now until I order a pair of 4000’s.

[Evan D]

You have the 6S version? You'll want at least a 5000mAh, honestly rated 60C or more battery. When you look at them post what you are thinking of getting as there is a lot of junk out there.

A 3300mAh is for a 70mm size jet, I even use 5000's in my 70's.

If you try pulling 120A or so from your 3300 you'll likely fry it.

Yeah for sure I was told on rcg as well. I was just worried about it being too nose heavy. I hate adding lead weights but I will mod the battery bay to move the battery (5000mah) further aft.

Turnigy 5000mah 60/120amp = 60x5 = 300 amp continuous. Basically 5000mah =5amp x60 = 300 amp continuous. If the edf is drawing 120 amp max you are well in. Turnigy Nanotech 3300mah 35-70c 1 115amp cont . i,e. 3,3ampx35. 120amp edf will be pretty much toast vey quickly as you are asking to draw more amps than the lipo holds.. Chris Wolfe RC Geek does a good video on the subject. in theory 4000 mah 60c minimum rating gives 4x60 240amp continuous which logically is double the max the edf can pull from it. Flight time will be less than a 5000 mah 60c. To guestimate flight time I use the following formula :-edf power calc for Avanti rhino 4000mah 50c 4/55x60x0.70 = 3 mins i.e 4amp hr battery consuming average of 55amp over flight time. The tricky bit is guessing the average power consumption and that depends on flying style. If the flying time is known for the Eurofghter on a 5000 you can use the formula to work out the ave amps consumption ad feed that back in for 4000mah to get a light time for the 4000. It works for me ! The Hobby Eagle A3 lite basically is a windy day gyro to smooth out the bumps, either on or off at the rates you set it at on a 2 way switch, no auto level. The A3 super 4 is a bit more feature filled, allows auto level, servo reverse, individual gains amount on rudder, elevator and ailerons. It also has 2 aileron and 2 elevator outputs which gives you more control and more choices such as servo reverse on say left and right canards and servo reverse on left and right tailerons I would suggest you ask Motion r.c. customer services if the A3 Lite works ok with the Eurofighter and how it is wired bearing in mind the canards. I prefer an auto level gyro to give me that extra second of recovery time in moments of lost orientation/brain failure .
