locharrow, truly beautiful work. I envy your talent. Best, LB

Thanks guys, it is just that I do not like the design of the skull. I , for my sins, and for all my "working" life, was a woodcarver/artist, My company specialised in carving and painting heraldic devices and the skull just does not measure up. I think I will just paint over it. Way back I used to hand paint all this stuff. Never used decals. The pic is one of my companies products....did them when I used to be artistic. .

[Elbee]

...is there a way to remove the skull transfers on the tail. I am not over fond of the design and would like to change it. It looks as if painting over them is about all one can do.

LA, When I removed all the paint down to the bare foam on my FW A-10a, I soaked paper towels with acetone and draped those over the model.

It lifted the OEM Paint easily. I wiped most of it off with the same paper towel.

Took a couple afternoons.

If I was doing a repaint and there is OEM water-slides/vinyl decals, I would use acetone and paper towels again.

Worth a try if you're repainting anyway.

Best, LB

If its a decal u need to remove it,, but it will pull paint,, water slide ,paint over and cant tell,, lb over on spitfire thread, gave good description, somebody also wanted to change scheme... one thing u dont need to use the latex paint.. i use auto paint( im a an auto body man) its not the cheap option , adhesion is very good.. u may have a hardwhare store to buy interior house paint,, they can color match, for u.... lastly do the grey f4 come with decals fitted now,, used to b 2 decal sets?

"Its fwing 1835 " Yes, I have the FMS 1835 and didn't realise Freewing made one as well. I just bought the Freewing 1750, it is supposed to produce 4600 - 4900 gms of thrust so hopefully that will improve off grass stuff.

On a different subject, is there a way to remove the skull transfers on the tail. I am not over fond of the design and would like to change it. It looks as if painting over them is about all one can do.

f4u...You talking about the FMS 1835? Have that in my new unflown camo F4...good motor..... this Freewing 1750 has redesigned blades and is supposed to deliver more static thrust. Unfortunately, I am so simple that I read it as "able to get off the grass better" That is why I need help !!

Its fwing 1835 was in my mig 17 not alot of use 12 blade last timit flew 430 minuts just a bit to long.. si will b good 4 f4 soon think its mayb 2 years old

Think I'll be stuffing this into the new F4.........Freewing Metal 90mm 12 Blades EDF with 6s 4068 1750KV ...all opinions appreciated....

I've got the FW 4068-1835Kv 12 blade inrunner in both of my F-4's. As a matter of fact, put those in my FW 90mm F16 and both of my FW 90mm F-18's. Love that fan and the sound of a 12 blade is sweet. I'm sure the 1750Kv will be similar to the 1835Kv, so you should enjoy it. More power than what was in those aircraft stock (although several were purchased early on when they came with the outrunner ). I fly off grass so any additional punch at take-off is well appreciated. I'm now flying all of those on the new 740 gr SMC HiV 5900's (used to use the 6200's which weighed 840gr). On the F-4, I have my timer set at 4:00 and usually come down there or at 3:50 (as much flight time as the 6200's or better since it lost some weight). Suggest you balance it close to the manual recommendation of 190mm. I'm at 195mm and like it there, as for me the F-4 really gets squirrely any further back, unlike all the other EDF's I have balanced 20-40mm further back. Just my opinion though.

I recently installed the Freewing 3668 1960Kv after having the 4068 1835Kv for about a year. Lightened the plane up, and on a 6S 6000 Admiral, I can easily get a 4 min flight time with throttle management.

Mine is the same metal frame, alloy i think,, with the 1835 kv.... dont forget to reset cg cause its heavier than the plastic one..

Beat you by two minutes f4u but closed it again! Fly as is I think although I'd love to do the Omega Sqd. scheme...

[f4u ausie]

Build it what scheme do like... yours is grey i think, i like the sundowner in grey just about got my wife convinced,, hopeing to order early next week and will be south east asia cammo ive never had a big box in the house more than 5 minuts b4 opening and starting assy.. little boy me... dont fget post some piks

[Evan D]

You're asking the wrong crowd. Build and buy another to store!

[locharrow]

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!!

[locharrow]

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!

[rlcamden]

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.
