I ordered new wings for my F4 that were damaged in flame out. The pieces pictured I ordered from Skymaster. They installed pretty straight forward and new wings are good to go after paint and weathering to match my older F4. Ended up ordering another one and I finished both at same time. Just went to Doc for my new glasses which I'm waiting for to do maidens on both

Any one have any pictures of how you made your canopys open in the scale position ?

Are the new wings composite? I have a 5yr old F-4 and the wings are glassed wood. Wondering if the new ones are all composite?

My F4 is 10 years old and had composite wings. New wings also composite

Sorry, my error, just double checked and the you are right, the skin is composite. Thanks for that, sorry for the confusion.

Hi,

About to start building one of these and I have a few questions for you guys: What unholy, demonic fluid (lube of some sort) is this they use inside these gear? I can't clean this crap off of anything. I've wiped it with acetone, IPA, bug-juice cleaner... no bueno. It looks like it's gone, but then you can see it the next day. And it transfers easier than my money to my wife's credit card accounts. Any tips would be great because I don't see how in the world I'm going to be able to paint these struts with this stuff everywhere.

Did any of you use button valves on the pneumatic doors? Servos? I'm planning to use BVM air quick-connects, but I don't want to have 5 of them hooked up.

Hopefully I’ll have better results asking here
I have a second hand phantom that someone did an electric conversion and cut away the engine bay formers.
ive contacted sky master with no help
does anyone have a tracing of the formers or a wrecked one that I can pattern

YellowAircraft

Hi,

I have a fresh one with an unstarted fuse. Maybe I can help. Which formers?

YellowAircraft

Hi

Looks like this one is missing the forward spar. Can anyone tell me the O.D. and length?

Hello Shawn,
With regards to your question about Retract setup.
I am building the 1/6 scale F4 at the moment and did not want all the connections either.

I will be using 2 x Ultra Precision UP3 Air Valves.
One for the Nose Retract & Door that will be mounted in the front.
One for the Main Retracts & Doors which I will mount inside the wing.
This way I only have one air line to connect between the Wing & Fuse for the retracts.
Running 4mm OD tubing for the air feed and will just use a festo fitting for the connection.

PS. Also changing the skymaster Gear Door cylinders to Ultra Precision brand cylinders.

Regards
Bruce

Thanks for the reply Shaun

I just measured my forward carbon rod spar ant it was 9/16 diameter and 27 1/2” long

Hello Shaun,

Please Ignore my previous message about the air valves.
This setup will not work with the 1/7.75 F4 as it has Plug in wings.. :-(

Hi,

Did any of you guys have issues with the cockpit interfering with the nose steering servo/mount?

Miniflyer

Hello shaun,

Yes the cockpit does not fit with retracted nosegear.
Also ailerons are jammed when flaps are down (one is top hinged,other bottom). The formers are glued in without the tanks being installed, making it impossible to install them. I am very very unhappy and it needs lots of work to get to a satisfactory level.....

I lost interest because i wanted a quick flying arf,and its been sittin on the shel untouched ever since delivered and inspected.....

Cheers hank

Yes Shaun. You need to cut away where servo bumps the bottom of cockpit. Not that much work to get it working

kevinthoele

My Feedback: (1)

Hank are you talking about engine rails. Mine are mounted with bolts as they were loose when plane arrived. Are you talking about 1 7 3/4 or xtreme F4? I have heard the smaller one does take a little extra to get it flyable

Miniflyer

Hello kevin,

All is glued with those whiteish resinish goo poodles, nothing with bolts, and no way to insert the tanks. I will throw them out anyway and go for bag tanks, so i dont care anymore, but for me the "ARF" in this F4 kit stands for "AlReady F§%$ed-Up". I will throw out all pneumatics and connectors, overdo the wing hinging, get the gear electric with hydraulic brakes, replace the banana thrust tube with one that ends straight and see if it can be finished in a somewhat good manor, but i will need time for that, which i currently just dont have.

Cheers

Yes I know it’s frustrating to fix their work. But last BVM kit I bought costs $10,000 and needed 600 hours to build and paint. Paid under $4k for 1 7 3/4 scale F4. I did have to fix some things but it is a great flyer. I have one Tam pipe straight and one original both fly good. The pipe needs 5 degrees down thrust so bent pipe facing down crests that and works well. Hopefully you will get motivated in future and finish it as you will enjoy once that’s done

Miniflyer

Yeah very sad. The stuff is simply too expensive what you are getting. Gladly willing to pay more to get something that someone invested some time in to make it work, but it seems the only time that was invested was the one to throw some resin in a plug and earn a fast buck.....

Oh well, started building some small add-ons.....here are temperature and AOA sensor in 1/7,75

I used button valves on my 1/9.5 F4. Also I glued a small magnet to the door to keep them closed during flight. The magnet contacts the steel axle bolt. See pictures.

I used UP valves for gear. I did have 5 connections but doors stay shut during flight
