Official Freewing 90mm Eurofighter Typhoon EDF Jet Thread

[Go4it]

Thanks, I did miss the different motor sizes. But when you do an ARF+ you can install what you want. I just finished an E-flite 90mm Viper and installed a JP 90mm 8S 12 Blades EDF Ducted Fan with 4250-1330KV Brushless Motor and as you said it was well worth it IMHO.

[xviper]

The motors are NOT the same kv. The 6s is 3668-1960kv and the 8s is 4075-1350kv. One is designed to be able to survive on 8s, the other likely will grenade within minutes on 8s at full blast. Of course it's the same manual. They aren't going to print 2 kinds of manuals just because the fans are different. Specs on the fans can be easily obtained on the respective product pages. Whether or not this would make a 50 buck difference, who knows. If one doesn't think it's worth the extra 50 bucks, there's the option of not buying it.
Personally, for my end use, the 8S was well worth the extra money. Had there not been an 8S, I would have purchased an ARF+ and bought the 8S EDF and ESC on my own and I can assure you (having done that many times in the past) the final price tag would have been MUCH more than 50 bucks.

The Freewing Eurofighter Typhoon 6S - 90mm EDF Jet - PNP is $599 and the Freewing Eurofighter Typhoon 8S High Performance 90mm EDF Jet - PNP is $649.
My question is what makes the 8S $50 more? Looks like the same motor KV and the ESC are 120amp. The manual for the 6S and the 8S looks like the same manual. So what am I missing?

John, have your heavy nozzles been proofed to work, fit and align properly yet? Look like they are going to be a necessary mod on this like on the Gripen and Arrows MiG-29.

Though mine showed shipped (label printed) and picked up by FedX yesterday it hasn't changed since then and still shows it in Grayslake IL.

Mine arrived and I have to say it's a beautiful piece of work. Pity about the CG problem!

The ordnance is 1000% better than anything I've seen on a FW jet before.

My nozzle aligns on the remains of the foam inside of the stock nozzle after the foam is cut back to leave a 6mm stub (so as to allow more room for lead if necessary, lead being denser than foam). I will include a 6mm measurement guide to help getting a clean cut in the right place. Each nozzle will hold (at least) 60g of lead, bringing the total weight up to around 100g per nozzle.

If you need to add tailweight, Radar-Guy's design is probably better if you're using lead strip or foil that can be bent to shape. Mine is designed to hold lead shot or small lead slugs.

I'll have my final version up on Thingiverse later today.

I also made Radar-Guy's tail piece. It fits fine, looks good, and has plenty of room for even more lead. The supplied "counterweight" is a steel cylinder, just 20g.

Mine is "Out for delivery", Radar-Guy's tail body is printing, the "afterburners" and heavy nozzles are ready. The weather isn't ready, and won't be for at least a week.

Ask Motion, they would be the only ones who would know.

8S can give anywhere from 25-40+% more power over 6S. Both the 6 and 8S set ups for this are new plus each set up has a little different performance in the aircraft due to ducting. Too soon to know for this aircraft and the stock EDF units or even aftermarket ones.

While the stock 8S will be significantly heavier than the stock 6S it's not an absolute all 8S systems will be heavier. My go to is a Jetfan EDF unit and a HET motor. The EDF unit is much lighter than the metal stock units and the HET motor is about the same weight as the stock FW motors. In this plane the ESC is a 8S ESC so no change there. What's left is batteries. Most people consider a decent 6S 5000 to be around 800g. I have good 5200 6+2 8S pairing that I use in other planes that is 895g and a 5000 6+2 that is 795g. So really at the end of the day not much heavier if at all and I get about 40-45% more power than previous FW 6S set ups and more flight time.

You can get the same from 10S and 12S choosing the right batteries.

Forgive me if this question has been addressed before - but does anyone know when the new 8S version will be available at Motion RC Europe, please?
There were some for pre-order but they are gone.

Also, what is the performance improvement likely to be over the 6S version, given the increased weight.

Thanks anyone who can help.

Looking for a convinient way to store extra weight in the tail section? Here's my 3DP design for a replacement tail body, It accepts the factory supplied weight.

Very nice.

So they are reauthorizing fields?

Yes, but only those NOT in controlled airspace. My main one will likely be closed all year and possibly for good, except for UMX planes - looking for a new location outside of controlled airspace. They are still in talks with Transport Canada and NavCan, but it's slow going. There are, at this time, approx. 50+ club fields (in all of Canada) that have been given permission to open. My secondary field (grass) opened last Monday. Strick rules apply for the open fields, although likely not unfamiliar to AMA fields.
I will only register my grass friendly planes this year. I'm hoping this Typhoon will work for me. I've flown other 8s planes there and they all work fine, except for sucking a lot of grass down their throats.

Got my shipping notice today also. Estimated delivery in SC on Friday.

No one has moved the MCBe and/ or cut the foam under it to move batteries back to help with the balance?

I brought my Typhoon back from storage (no, still haven't flown it due to snow and cold) to my hobby table so I can look at unscrewing the board and moving it as far back as possible. This will possibly allow one of my twin batteries (mounted on edge) to slide back a bit further to achieve the desired CG. At present, with both batteries (2 X 4s) together and right to the rear lip just in front of the board, the plane balances a few mm aft of the marks. I'd like to be able to move that back a few mm more. I'm not sure if this is necessary for those who have the 6s plane. I guess they'll find out very soon.
Our grass field was just allowed to open under MAAC and Transport Canada rules, but it'll be sub-zero C temps for a while yet. I plane to fly it fully loaded off grass.

…
No offense to Radar-Guy but I designed my own heavy nozzles anyway, since I had nothing better to do.

No offense taken!

[kallend]

Just got my shipping notice. Delivery : Fri, Dec 23, just like Evan's, which is the same as they said on Dec 18 2022 when I ordered it.

Being in Chicago, I expect it will arrive tomorrow IF FedEx picks it up today in Gurnee.

Many times I get shipping notice but FedX doesn't take possession until the next day. Since this is a large shipment done early hopefully FedX takes possession later today and not tomorrow.

As you say this weekend doesn't look good. Plus I figure a whole day for the tails decals... At least the decal setting solution says overnight. I am bypassing the MCBe for all functions except gear doors, retracts and lights. Plus adding a steering gyro and figuring out weights and balance, so I'll have things to do.

[TGoelzer]

Me too. Email says "Estimated delivery Friday Dec 23".


Going to the FX website says this Friday but I doubt that will happen.

I live in Fort Mill, SC and usually if it ships on Wednesday, I get it on Friday. We will see?

Not going to be a good weekend for flying anyways. So if it comes by the weekend. I'll put it together, but that will be all
