Official Freewing 90mm Eurofighter Typhoon EDF Jet Thread

[50 Fly]

I understand 100% 50 Fly.


Everyone needs to realize this is a 100% new design with nothing in common to the V1/V2 except the name and fan size. Just like the newer F/A-18C is nothing in common to the old V1/V2 FA-18E.

Yes, re-read and I get it now. Makes it doubly disappointing they chose a gear design best for pavement, that they didn't stay consistent with what has made so many jets successful from grass. I've been converting a number of EDF's to turbines, takes a lot of time so need to have it right. "It all starts with the gear"! Might be able to re-trofit A-10 mains to the Typhoon, if wheel wells will allow. Maybe someone from the factory could chime in? Alpha?

There are not any plans for a German version right now but it is something I can suggest to Freewing for the future.

Okay then well, I'll just have to be patient!

First, what a great model this will be! I have been one of those folks trying to get you to make another Eurofighter, or just release the old version again. I have a question however, will there be a German version? Thanks very much for your time.
I don't fly my V2 version ever, because I couldn't fathom losing it.

I have to think they wanted to keep the gear more scale looking. Since it's a totally new aircraft I don't think "too big a revision" had anything to do with it.

My opinion has always been that these should be flown from a paved runway for best results.

Didn't know it was an all-new design, guess you could be right about the scale appearance, but I hope that's not it. Why? How many guys look at the A-10/MIG 21/F-4 etc and say "shazaam, that gear is way off." Especially when main gear strut covers are used, the look is, IMO, unaffected, yet the functionality is GREATLY improved. Agree with you about paved runways/better results, of course, but the several clubs I belong to that are large enough for jets all have grass runways (like the majority of fields in the U.S.) In my fleet, all jets with some form of trailing link gear have zero gear problems, even on the roughest field. However, those with straight legs are "iffy". Depends on the mounts, the field, the landing. Straight legs, even with some form of vertical compression, do not dampen the shock loads encountered from taxiing/takeoff/landing like a trailing link. The difference is easy to see when taxiing with good trailing link gear. They're very "active".

Well, that is interesting. All the specs and product are 3668-1980. Interesting the manual says 3668-1960. Good catch. I'll ask Freewing if something changed and which is correct. I'm working on tiger vs no tiger decal. Ideally, the tiger decals would be in the box but it may be waterslide and extremely difficult to apply on the tapered/curved surfaces. In that case, its better the factory apply them.

Thank you!

Thanks Tom, ordering now.


Thanks again!

I verified the 120A ESC is the same in both the 6S and 8S version of the Eurofighter. Freewing also verified they use the same version. I have the manual for the 120A ESC used in both the 6S and 8S version and Todd is going to post it on the Eurofighter support page later today.

Anyone else flying from grass fields wish they'd have incorporated trailing link gear? I thought Motion/Freewing had "seen the light", so many other recent releases have incorporated this critical "cheat". Maybe too big a revision? Wish I'd been a fly on the wall during that discussion....

I had the original Eurofighter and it had a kind of trailing link front gear. I flew it off very rough grass and it was able to get airborne. The trouble with the trailing front gear is that due to the short wheelbase of this plane and the fact that the front gear is so far aft, that trailing link front suspension collapsed on the gras when powering up to take off, causing the nose to go down, reducing the angle of attack. Sure, it would have been nice to have trailing links for the mains to absorb the roughness, but they still worked OK. This new one doesn't have trailing link front or rear. I think the front will handle grass and rough ground better and I don't think the mains will have any trouble either due to the more powerful drivetrain. If you are a heavy lander, then trailing links for the mains might be better for you, however, the compression struts on this new one looks pretty beefy.
This may be one wish that's best left unfulfilled.

Waiting on Toms answer about the ESC. Wife has said buy either or both (I still teach for the company I retired from and they gave me a 70%+ raise to keep teaching next year plus SS won't penalize me as much now)...

I'm leaning towards the 6S. I like that it has a plastic shroud but the motor size worries me for longevity. That said its the same size as a HET 650-68 motor. I have a HW 120HV ESC NIP and a JF/HET fan in a drawer if I want to swap it out.

If I do get the 6S I'll probably do a thrust/ Amp/ Watt test and decide.

[JamesonC]

So many new things and so many changes....

Evan, if you end up buying the 6s, I'll buy the EDF from you when you pull it out if you want to sell it.

As I said....

The V4 6S does reverse. Or at least I thought I saw somewhere with updated programming it can. I hope Tom can verify. If the 6S has the HV then that's the way I'm going as I have two spare 8S JF/ HET fans in a drawer..

From the V4 6S instructions. HW-SM040DUL_Platinum 80A-V4&120A-V4说明书_160125 (shopify.com)

11.2 Reverse: after selecting this option, the RPM signal wire will turn into a reverse signal wire (the signal range is in line with the throttle range). After setting a channel on the transmitter, when the reverse signal length is above 20% signal length, the Reverse mode will be activated. The reverse signal length must be below 20% signal length when the ESC is powered on for the first time. When the reverse signal length is below 20% signal length, 0-100% throttle corresponds to “CW”; when the reverse signal length is above 20% signal length, the motor will stop spinning CW (and then spin CCW); at this time, 0-100% throttle corresponds to “CCW”.

So there could be a 6S in the 6S version and the HV in the 8S version.

I stand corrected. Just read that same manual.

Thanks. The reason I ask about ESCs is HW makes a 120A 6S V4 and a 120A 8S V5. They are different. I assume the 8S for the 8S plane but what about the 6S version? Small differences but it makes a difference in which version I order.


And thanks!!!!!!

Do the 6 and 8 have the same 8S HW ESC?

I would be fairly confident that it's the same one from the link below. They are for 3s to 8s. I use a couple of them in my 8s jets and also use one in a 6s jet to get the reverse. It's the only reversing one in that amp range. It also seems nearly identical to the FMS Predator reversing ESC, 120A, HV. I use a couple of those as well. Except for the label, can't tell them apart. Even the programming is the same. The HobbyWing V4 doesn't reverse.

Thanks again Tom.

The 6S PNP motor is 3668-1960. I just checked and verified this. My spare parts list has only one single 120A ESC with a single spare part number. In theory, this means it is used in both the 6S and 8S version. I'll try 8S and make 100% sure.
