F-4 Phantom foam Parkflyer

[MJH]

Hello,

Inspired by Steve's F/A-18 I decided to build one of my all time favourites F-4 along the guidelines set by Steve's ingenious design.

Maiden was today and it is a really nice flying park jet.
It is similar to F/A-18 and F-15 in all dimensions and weight, so it is doable with the same powerplants those 2.
Mine flew with GWS motor.
Apart from needing to tweak CG, flight offered no surprises, the thing flew just fine. My battery was too light to get CG right and I need to move it (CG)about 1-1.5cm more forward. Elevator was just a little too sensitive.
Being really carefull on elevator it flew nice. It will fly in small areas just as well F/A-18 does.
I only have inboard flaperons and aileron response is much slower than what You might have gotten used on Hornet, but I think that Phantom is not that agile to begin with. I does a nice roll though. Still a little disappointing, but not terribly so. Flaps really slow it down for landing.
Only one flight was made. I think my esc got a little too hot, since there were some cutoffs on the engine noice. I need to modify tail so it gets some cooling air. My setup is pushing esc and motor hard.

Sorry, no photos of maiden, I was alone. A couple of guys showed up after landing. They were asking where i bought it ;)

Do not ask about the plans yet, unfortunately I can not make them availlable, at least not yet.

Some pics are here.

[Tomcat Fan]

Very sweet looking plane.
Without "asking" for plans, we ummmm.....
look forward to hearing about the progress in memorializing how one might build such an aircraft.

[Darren Hintze]

Another beautiful plane that REALLY needs some fans in it.

You guys are killing me. Man, I love F-15 and F-4 (I already have an F-18 in the squadron). I guess it's fortunate these aren't going anywhere because my list of "must build" planes is getting longer and longer and longer.

AWESOME looking F-4. Great job.

Darren

[MJH]

If You guys are dying to install fans in Hornet or Eagle, You are about to be done when You see this. It would be ideal for some really hot 55's.
U want fans, this would be the plane to put them in! I have been thinkin and drawing some sketches allready.
I do not have knowledge or experience on ducts, but should not be too hard on F-4 and exhaust end is clear. Servos for flaperons could go to wing or wingroot...
Its lightweight construction, around 10 oz with paint, GWS motor and servos minus receiver and bat

[Ralph A. D'Amelio]

That is so cool...again one of my favorites.

Ralph

[borabora]

Man! That's cool, that's more then cool! Perfect! :)

A question, any nose down pitch problem did you get due to your thrust line is little above of the design thrust line of the jet? If not, you will going to open a big door for me :)

Bora

[jetset44]

Great work, Matti! Looks very good and glad to hear it flies so well. :cool:

Yes, it's too bad the tip dihedral of the F-4 makes it not practical to have full span flaperons...

[MJH]

Bora
No pitch down problems. Will know more of that whan I have chance to fly it more. Weather is supposed to be crap for next couple of days. Need to fix CG and get esc heat sink into open air. As i said, it was a little pitch instable, but me thinks due CG problem. Battery was not heavy enough. If this thing developes to a plan at some point, I need to figure out how to make tail lighter. Not an easy task, it is quite simple as it is.

Jetset
Did You read Your mail? With some thinking, I am sure someone will find a way to make working lightweight full span flaperon. I was in a hurry to get this thing airborne before I get too busy doing something else.

My bird is a prototype and should be considered as one. It has shown potential to be really good flyer, but before it is something like Steve designed, there are several things that need to be sorted out.
I can live with less effective aileron response. CG and the weight in tail is more of problem. I use a relative heavy battery pack (8xKAN650) and if You are going with lipo pack, You would have to add weight to nose. Not good.
As an airplane, I think it is quite ready. It looks good in the air and I don't mean the looks of it, I mean the way it flies. Even with sensitive pitch it was ok and easy to fly. I even rolled it couple of times on maiden.

[iflyprops]

There is a little ducted fan F-4 built by Estes (a friend just bought one for $50 at Wal-Mart) that has a little cruddy fan and only rudder (I think) that is just begging for some mods...

[MJH]

I am willing to share my experience on this plane if someone else is willing to make a plan based on my sketches and pics I took durin build. I have about 100 pics from te build and details over the plane.

I do not have the CAD skills to make he plans myself and right now I don't have the time to learn them, so I am offering the material for someone to do it.
I can also point the necessary mods needed to make Phantom ready for "serial production". Those minor problems can be solved and I allready have some ideas on how to.

I designed my F-4 by doing rough sketches with ms paint over 3-side wiev downloaded from the web (nasa pages I think). They were printed to the size of the model and the rest I figured out as I went along the costruction.
Construction was simple and plane feels strong and solid, even though I used depron doublers on the corners. They gave nice round shape on the fuselage.

So, any interest on the plans?
It's my contribution and I also offer my experiences to improve the design.

Hope steve is reading this and is able to make us a plan for this wonderfull F-4 ( ever a dream of me since my childhood) :)

Greetings from vienna

Rudi

[MJH]

I have been in contact with Steve.
We know he is busy with Gripen and T-38.
Lets not ask him too much and be happy with what he has done allready.
I am sorry, but I can not do them by myself any time soon, (like 6 months).

[the agent]

excellent. great job. i tried to do the same but i got a little frustrated with the set up for the elevator. this might just serve as motivation to get out the fanfold. good luck with the changes

[MJH]

Any help from this?

[MJH]

Flaperon servos and elevator CF tube. Its got pianowire going through and bended to anhedral. It is flexible enough to save mechanism in case of ...
Elevators are secured with ply doubler and epoxy to take aerodynamic forces at high speeds, but those should crack when tail hits something hard.
Aplied too much pressure when gluing 10x10 stock for motor mount. It got tilted so motor is off centered.

[Ben_E]

Great looking F-4!!

I can assure you that you are not the only one with bad weather!!!!

Hi MJH,
If no one else has beat me to it I'd be willing to draw the plans for you in CAD.
Please send me a PM with how you'd like to get started.

Flew 3 more flights, CG is about there now. Some more reprogramming on radios and its about ready.
I have a video but I need to figure where to host it.

[MJH]

One more..

[Spinner]

Matti,

Wow! Really nice job!! More, more, .... :)

Joe

[GregG]

Man the Phantom looks great!!!!!

You can always use the gallery here to host your video.

Really nice Phantom Matti :) Look forward to plans/video for sure !
Weather looks good ,no snow yet ;)

Video posted on my gallery, dont know if the link works.
Nothing fancy, just flying around. It was windy day so I chikened out doing low level aerobatics on my new bird, especially since the flight controls have to be reprogrammed before it is really finished. My digital camera does not have enough zoom to catch things at altitude.

Snow would be very wellcome, Ground absorbs models much more friendly when covered in snow. Plus I like skiing...

awesome F-4!!

Barry

[monkamarm2000]

Man looks so cool in the vid too!

Barry

[MJH]

Thanks for the response! I love it too. One fun part of making the plane is to make it ready, really ready to fly. All controll throws and CG and systems and so on.
I have written Dan E and he has promised to look into making plans.
Patience...

[jetset44]

BEAUTIFUL photos, Matti! Wow, that model looks very realistic in the air. Great work!!! :cool:

Steve

[Arbo]

Great job on the F4. Looks good, seems to fly good. I was shocked at the size of it when you launched it, much bigger than I thought.

Paul

[MJH]

I have said it, it is about the same size of F/A-18 and F-15 park jets. They are large enough to get the attention in schoolyard.
I think it was Steve who explained somewhere in the enormous F/A-18 thread about those scale speeds of these jets.
F-4 could and propably will get more speed when I upgrade it with BL.
Somehow I think that this bird needs to be fast.

[jetset44]

This point is really interesting to me so I'll expand on it. Believe it or not, all of the Park Jet-sized models (F-18, F-15, F-4) are flying at very near scale speeds. The full-size jets spend most of their time flying around 300 to 500 knots (typical combat speeds), which at model scale equates to 21 to 36 mph. Since the Park Jets spend most of their time flying around 40 mph in typical manuevering, they're flying slightly faster than scale speed but remarkably close!

The top speed of the Park Jets is usually about 50 mph, which equates to a full-scale speed of 700 knots or about Mach 1.1 at sea level--faster than you're ever likely to see the real fighters fly since they don't break Mach 1 in front of spectators. :eek: However, the real jets are capable of 800-900 knots max speed which equates to 64 mph at model scale. That's not achievable with a brushed GWS EPS-350, but is very achievable with a Himaxx 4025 or Mega brushless.

Stall speed of the Park Jets is about 15 mph, which equates to about 200 knots full-scale. That's a little hotter than what the real jets land at, but not by much (they usually land at 140 to 180 knots).

Interesting, huh? :D There's nothing wrong with wanting faster-than-scale speed, but I just think it's interesting that the Park Jets are flying at pretty much scale speeds.

Steve

[Trbdsl96]

That F-4 looks sweet! It would look awesome comming in hot on the deck!

[bildo baggins]

Congrats on faithfully reproducing the meanest looking fighter in the inventory. (Past) I have always loved this one and when stationed at Davis-Monthan AFB I visited the aircraft graveyard many times and always gravitated to the F-4s. Really flies well and looks very realistic in the air. I bet BL is gonna put her in AB 4!
Bill

[empeabee]

Now we need a THUD & MIG15 to fly with it.. :)
Mike

[Al Dente]

I don't want the plans for that ,at all,no,really don't.This thread is only in my favourites folder because of a dumb thumb,or computor glitch,perhaps I had a little too much Vino tinto.Not interested in a great plan of one of my all time favourite birds at all,so don't bother,any time soon,or ever.Unless of course you feel you must,may take a casual glance and have one flying within a fortnight.Good stuff,regards ,Al.

[the agent]

thanks for the peek at the elevator setup. looks great in the air how is roll response. you did a great job, nothing like old school heavy metal in the air. awesome!

Al du u mean vino tonto ?? :D :D :D :D
Mike

[MJH]

Thud and MiG-15? Thud would be nice, though.
I think there are enough 15's around here in, but rumours have been circulating of MiG-23 coming up to challenge Phantom.
Quite a few of the late 60's early 80's era jets are doable this way.
And as many have demonstrated, they can be finished to look really spectacular!
I really like some of the painschemes F-15's are getting and he Blue Angels scheme on Hornet is classic.
I have not paid too much attention to finnish and feel bad about it too.
I keep telling myself, that flying these jets is the main thing.

[Rudi]

Hello MJH,

are you able to post more building step pictures ? This can help in making a plan for the F4 .

Thx

Rudi

[MJH]

There is a project coming along to produce a plan. I have mailed my sketches and construction photos to Dan E and he has kindly agreed to look into making plans.
These things do take some time, please be patient.
I still have some more flight testing to do to solve some minor (now) glitches.
The plane is allready flying quite well, but I still think some improvements are still waiting to be made.
And I just need to test it on BL setup.

[erunway]

Great Work MJH

Waiting patiently... heheheee...

[Tomcat Fan]

Phenomenal Phantom.

......waiting.........hoping.........

Anyone have an update?? Plans, plans.... :)

Thanks

Nice St. Louis pride ;) McDonell may lovw this pics if thay see it.

Congratulations, a very real shape.

Cheers.

[MJH]

I can't read my email right now, so I don't know about the progress.
I still haven't had time for more flight testing. The bird only has 4 flights total and I need to play with the CG and control throws little more to have good suggestions for the plans.
The problem is that at this time of year it's dark when I go to work and it's dark when I get home (here in Finland). I need to take the plane to work if I want to have the flights done during the week. You know what the boss might think about that....

[pacro]

I have a eurofighter thats also built using Steves methodsi .e. laminated depron canopy, hollow shell. will post pics soon if interested

[bildo baggins]

MJH - You must convert the Boss. He MUST realize the importance of such things.

[Dave Barrow]

Great looking F-4, will be watching with bated breath.

[eatond]

I can't read my email right now, so I don't know about the progress.

A quick update. My father-in-law passed away last Saturday which caused us to take a quick trip to a little town in upper Michigan. I didn't have net access so things had to wait until we got back yesterday. I've got all the stuff from Matti so now it's just a matter of sitting down and getting it done. Based on what I've looked at from Matti I think it'll take about a week to get the plans done. But first I have to finish wandering through all of the new posts since last week. :rolleyes:

[Paul DF jet man]

maby a twin edf version of the F4.

[MJH]

I was talking with my brother about the twin EDF evolution here.
I need to educate me about the ducting for the fans.
It should be doable. Good thing is that duct is straight and exhaust is clear of obstrutions. Bad is that duct is long and intakes would have to be enlarged a little.
I think there is a thread with depron F-4 on twin GWS edf50 gear. It was modeled along early PC-game model and is kind of boxy in design.
It flew, but I dunno of performance.
If someone decides to try this, I would suggest fans around 55mm and some really hot BL motors turning them. EDF efficiency is not all that good on the speed range this is designed to fly. Prop is the thing here.
More weight, more speed and more sructural work, more speed and more power and more weight... You know where I am going.
I think it is doable, but I do not have the resources to go there.
My idea has been based on feigao bl turning gws 50 fan, I still have not found out how much thrust thy can deliver.

Hello MJH,

I agree with you a edf version of the F4 would be nice but I will start also with a pusher version ! ;)

Rudi

[Tomcat Fan]

MJH, which GWS motor did you use?
Could it be?
A plane I could aford to build?

[MJH]

Tomcat Fan:
Dunno of Your budget, but propably not smaller than mine!
The facts:
Regular size receiver will do, I use 8xKAN650 pack, GWS EPS 350-C with "1"-gear, three 9g servos, jeti ESC (10amps?). One 5mm CF tube and one depron sheet. Some bluefoam for canopy and standard foam cups for ab nozzles. GWS or APC 9x6 SF prop.
That is just about as cheap as parkflyer can be.
I had to buy new servos or F-4, everything else I had.

I Did finish flight testing this morning (-8deg C, windy).
I have now CG range and control throws and incidence to sugest if someone decides to build one.
It does a loop with this setup, rolls a little slow and it is very stable inverted. Climbs good, both inverted and upright.

Flight controls use Steves flaperon elevator system. It could use outboard ailerons, but I found no easy way to do them. No elev to flaperon mixing.

It turned out I had way too much elev travel to begin with. CG.was ok where I first started with.

Flies good, it is a true parkflyer. It's kind of funny to see F-4 turning on a dime.
I'll try AB (brushless) version propably next weekend.

[beanie]

sounds awesom mjh!
any chance of posting plans?
-beanie

[Ralph A. D'Amelio]

Good Show!

[eatond]

any chance of posting plans?

The plans are getting pretty close to done. I just sent Matti the latest revision and I'll try cutting out one from the plans after I get his feedback. Once we know you can build one from the plans I'm sure Matti will release them.

Dan Eaton

[MJH]

Hello!

World has room for more Phantoms.
My version has now plans availlable for those, who are preferring to build by Steve's style.

Dan Eaton kindly agreed to put his effort and time to produce the plans based on my design of the F-4. We have worked together on the plans he drawing and me writing details.
Whole thing is inspired byt Steve's F/A-18, wich I build when the thread was about 2 weeks old.
F-4 build is fairly straight forward and studying the building techniques in F/A-18 thread Phantom is easy to build.

I will be writing control throws info and some F-4 specific building information here for those of You who decide to build this version of Phantom.

Dang, the files were just a little too large.
I'll see what I can do.

[Spadinator]

I Can Hardly Wait!!!!!!!! :)

[radiorobertert]

Tomcat Fan:
I have now CG range and control throws and incidence to suggest if someone decides to build one.

I would like to know.
Also how much dihedral on the wing ends?

Rob..

[MJH]

Sorry, try now.
Lets blame Bill...

[Spadinator]

Woo hoo!!! Got em thanks!!

[MJH]

Tailpalne setup

Doing the tailplane I used CF tube left over from wing as torque tube. You need to bend steel rod to proper angle, one for each tail surface. Epoxy them to elevators and then fill torque tube with epoxy and just plug them in. Be sure to rough up the steel before. Elevator throw is 1,5cm up and down with some incidence (up elevator) as neutral. I do not have the exact number here.


Flaperons
Do not expect really snappy control response. Plane rolls good but is not as quick as F/A-18 or -15.
Flaperon throws are about 2cm up and down, about 1 inch. I use 1cm down for T-O.
Place flperon servos as close to cg as possible.
Use regular foam coffeecups for burners.

I would try to locate all the radio gear (esc and rx) in front of the cg if Your battery is less than 100grams on motor is heavier than gws EPS350C.

I'll post some construction pics later..

[Ben_E]

Thanks!
They look great!!

[MJH]

I hope these are self-explanatory.

Still more pics..

[Spadinator]

The potos were very helpful......Awesome job!!! I can't wait to start building :)

[kscbob1]

By Incidence do you mean that the leading edge of the stabilator is 1 cm. lower than the pivot point when extending the Armament Data Line (ADL) from the pivot point?

Bob

[Spinner]

Matti,

Thanks a million for sharing your plans. :) After I finish my F-18, I'm going to try to build the long nose/Gatling gun F-4E used by the Air Force.

Joe

[fuelsguy]

Great F-4 design. I just finished a very similar design and was starting to cut out the depron when I spotted this thread. Interestingly, mine is 28.5 inch span. Steve's guidelines on wing area do work.
I'm playing with moving the motor forward and using a long prop shaft. This will move the motor weight forward and help CG. There's a thread on a small F-14 in the scale forum showing this idea. I should have my version built in the next week, so I'll post notes on my trials and tribulations on the use of a prop shaft. Anyone else tried this approach?
Ivor

[Ralph A. D'Amelio]

Thanks Ralph,
I've done a lot of CAD work for myself but never actually drew up a formal set of plans. I basically followed the format Steve Shumate (jetset44) used. It was a good learning experience.

I'd also like to take a moment to thank Steve for his help. He was nice enough to produce the tiled version of the plans from my drawing since I didn't have that capability. One thing I really like about the folks in this forum. We all tend to pull together. :)

Bob

No, I mean 1cm lower than trailin edge of elevator, not pivot. See the picture, It should make things clear. Sorry for inaccurate expression.
That is for incidence. The elevator should be set neutral along the red line shown.

The pivot point distance is mentioned to help getting right amount of travel. There is still little too much travel and about 40% expo is recommended for elevator.

[Rudi]

Hi Matti ,

Many , many thx to you and your partner ! :) After finishing Ralph's F4 I start with yours ;) It is nice, you make the incidence with the elevator and Ralph make it with the wings but both are the same in results apr. +1,5 degr :)
Here are 3 photos from my unfinished F4.

Greetings from vienna

Rudi

[kscbob1]

MJH thanks for the clarification and the beautiful F4.

It's amazing how cold it gets up there where you're at, I worked in Imatra the summer of '73 and again in Kouvala in the summer of '75 installing process control computer systems in paper mills.

Bob

[Spadinator]

Does any one have a photo of the T-bird paint scheme top and bottom? I found several photos of the phantom as a t-bird but nothing of the bottom.

Wow, you jarred my memory soo hard I almost fell off the chair. I had a set of four F4 Thunderbirds hanging from my ceiling, making a banked turn in a diamond formation as a kid. I loved those :)

I did a quick Google Image search and came up with these. The one decal set is on EBay.

[Wind Slave]

One more..

[Spadinator]

Perfecto!!! :eek: I remember as a kid going to watch the T-birds as f-4, t-38. and now f-16. The Phantom was my primary bird when I was mechanic in the USAF. Many thanks for the photos!!! Can you guess what color scheme I will be using? :p

Now you'll have to build at least four of them and run them all on the same frequency. Just line them up on the runway wingtip to wingtip and roll 'em out :) :cool: ;) :D :eek:

[Spadinator]

Ohhhhhh Yeah!!!! :)

[beanie]

thanks so much for the superb plans MJH!
i'm about to get started. quick question, how do you keep the wing tips set at an angle? did you cut them apart, sand in the correct angle and then reglue? or insert plywood guides to keep the angle?
thanks
-beanie

[MJH]

Beanie, just cut them apart and epoxy. Sanding is a good idea.

Thanks for the plans go to Dan, he made good job on them.

[MJH]

Oh, ONE more thing.
I used double sided tape on proto to install servos.
It does not hold the servos secure enough. I recommend doing some kind of bracket for the servos from depron. Look for the pics for servo placement. Flaperon servoas are inside the ducts.
I had abuse language some after couple of flight at low temperetures to do just that.

[MJH]

This Phantom is good canditate for ROG.
Prop is high enough to give reasonable clearance without making mains too tall. Add servo for steerable nosewheel and off You go.
I'll propably test this indoors next after xmas.
I'll update to BL power during holidays.

[radiorobertert]

All done except for Decals

[Dave Barrow]

radiorobertert, looks great, love the paint scheme.
