Big box arrived today ....................store it ..... or build it....

[locharrow]

Some great info their by all.... thanx everybody so much for ya time and locharrow i did notice rc castle advertise their 6s with 1950 kv b safe happy flying

.Seeing the 1900 Freewing and it has more static thrust than the 1850 so looks like a winner. Some of you boffins can fill me in on how 4300g translates through from static to in-flight power (please) Mainly interested in getting improved performance off grass!!

Found it its 1835 kv 12 blade inrunner with the 125 gecho esc, i undersand the weight diff the latest 6s f4 have 1950kv or theirabout will the 1835 i hav b good if i start 6s then convert to 8 s

If it is the FMS 1835 then that is ideal for the F4 ....not a great increase in thrust over the stock Freewing motor but sounds better. . I'm hearing about a new 1900 Freewing unit but don't see anyone in this forum using it. Wouldn't mind giving it a try in the NEW GREY F4 that arrived at UK customs today !!! Be another week before it gets to Scotland!

I would agree with Evan D. I had the 1835 setup in mine for a couple of years. After trying the 8S setup, I reverted back to the 6S w/ 1835. Same performance, lighter weight and with good throttle management, good flight times.

[Evan D]

That's a great 6S system. leave it 6S.

Is the MiG17 fan and ESC the stock one? It’s not enough for the FW F-4.

This one is special. We, the British, took the F4 Phantom and give it some real class............none of your Andy Warhol stuff, more ..........Gainsborough........

Hi guys looking at my next one for the hanger(they r slowly increasing yea) hav had my eye on this for a long long time... but new i needed to improve my skills.. jets so far dynam me 262 a puppy,, avous mig 17 also a puppy.. then 70 mm fwing f35 and struggled a bit with that,, now have al37 easy peasy,, im not sure about 3 min flight times on this,, its not long... i have a hi perf innrunner and esc ,out of the mig,, but can get an 8s here for not alot more... so u guys may me help on the 8s flight times,,, lastly i can get a fwing couger instead ,,, may b better choice, b4 the f4.. just not sure which way to jump thanx in advance

Agree with Evan, the 8S version is outstanding. With that said, I'm not sure your next EDF should be the F4. Don't get me wrong, I love it and have 2 of them, but it flies a bit different from other warbird EDF's. I got my 1st one as soon as it came out, but it was only my 2nd EDF after a Stinger 90. It took me a while (and I got a lot of practice and proficient at repairing foam EDF's from this one ) to learn how to fly it. You need to fly it scale and it won't disappoint. No slow high alphas, which it does not recover from, and needs to be balanced close to the manual. It has no cheater air holes so can "starve" for air at the wrong speed and orientation. On all my EDF's I'm a minimum of 20-40mm behind manual recommendation, except this one which I fly at 195mm, only 5mm behind manual recommendations, so it definitely likes to be more nose heavy than others. Any further back and it gets twitchy and a bit unstable. You've got to get your landing skills down pat, slow enough to land with the nose just up a bit (otherwise you'll break the nose pin) but not so slow it stalls. It took me maybe 20 or more flights to feel comfortable with it, but after you do, it is one of the best flying EDF's I have, usually the first in the air to get my juices going. With that said, you may want to go with the 8S Eurofighter or F22. Both fly very easily and landing with the nose up is a breeze, as they both seem to want to stick their nose up at everyone when coming in at about 25% throttle. Just a thought, others might feel different but that's my 2 cents.

[Evan D]

1390kv? 5000 8s should be good for 4 minutes with throttle management.

that would be a great set up for the F-4

[f4u ausie]

Esc is gecho 125 cant find the fan will after work

[f4u ausie]

Its a fwing comlete unit

[f4u ausie]

No of the top of my head the mig was 1500 kv out and upgrada to alluminum cas 1930 kv innrunner and 125 amp aftermarket hardcased esc from motian.. cant think of the name

Another impressive pic.....

Ok Hugh good to know. I've been looking around for those SMC hiv packs,but on this side of the planet they are very hard to get.
I'll keep flying the Zee packs I have for now and hopefully soon SMC or a distributor will get some stock.
There are times when I envy you guys in the States, between free post deals with kits I read about at times, availability of parts it must be great being in a much larger country with a far bigger market to cater for compared to Australia and with good reason might I add.

[locharrow]

"For me, the F4 gets squirrelly too far back and stalls easily," Not only the plane that gets squirrelly when the CG is a shade too far back Hugh! ..found that out when I had a loose battery strap. . Editing late afternoon...just back from first afterburner flights...excellent.....love it .
