F-14D

[MCMF]

Some more updates...

Riging of the air valve try with pushrods connected and air lines too...
Second , final installation of the starboard engine in the fuselage .

[MCMF]

Now with both engines in place and arresting hook too....

I'm planning on having the arresting hook to operate with the aid of a servo but by no means will it be a fully functional one...just 4 scale apparance

Yes....

מרכז הכובד משתנה עם תזוזת הכנפיים,איך מתקנים בשלט ?

תודה,
ארז.

[MCMF]

Center of gravity shifts during the transsition of the wing movement but so does the Mean Aerodynamic Cord possition relative to the fuse and with it the A/C further than that the wings pitch attitude changes too ( while folding back they pivot upwards by a few degrees) with all these changes the resault is that no pitch trim is required.

[MCMF]

Next it's time to deal with the ventral fins installation this was done by inserting threaded inserts into the fin base with the aid of a few drops of structural glue.

תודה על ההסבר. (תרגום בקצרה...מרכז הכובד אכן משתנה, כמו כן משתנה זוית התקיפה של הכנפיים, לכן לא צריך תיקון בשלט)

[MDreamer]

so what´s you are saying that the wing movement is coordinated with the CG?
How do you calculate that? before building...

[MCMF]

Do I really need to unfold the analysys done to prove the maths?

I might show it at some point in the future the difficulty lays with the fact that I don't have it in the right form of media...i.e I will have to scan quite a few papers to be able to upload them here...besides I'm not sure I am willing to do that...

to satisfy you eager to to know how it's done, I can explain it you on the phone....or you may enter RCU and look it up with the guys who build the "Bone" bomber ...they did the same with their design too.

but you can look it up

[MCMF]

your transllation lack somwhat.....the wings AOA doesn't change the incidence does relative to the fuselage center line..

[ZvikaF]

מתקדם לאט...
לפי ההסבר שכתבת יש שינוי בזוית ההכונה בין מצבי הכנפיים וזאת כדי לנטרל את הבדלי מומנט ...

[אייל שפירא]

לא, אין דברים כמוך, אומן רנסנס ממש.

Second , final installation of the starboard engine in the fuselage .

Seen on the upper left corner of the tray is a gadget from Tam-Jets which functions as an air pressure failsafe system that lowers the gear in case the dialed in minimum pressure drops under this value due to a leak of some kind.

[MCMF]

Rigging of wiring and air tubing in the starboard side of the fuselage....

[MCMF]

Here is the preparation of the master switch box that will carry the various switches ,fill valves and air pressure gauges,

[MCMF]

Here we see the final installation of two out of four fuel tanks in the fuselage these carry some 1.7 Lt each ..total fuel capacity for ecah engine is 4.2 Lt.. without the hopper tanks

[MCMF]

Next is a particular reinforcement area on each one of the two larger fuel tanks..

[MCMF]

Hope all goes well ! Seen here are the four fuel tanks fully fueled ... leak test

פטר
כל הכבוד
נראה עבודה נקיה ואיכותית

I konw it's been a while since I posted any new info on the project but here is my "new thing" I have created this new tray out of plexiglass ....I just couldn't ressist it...I had to give this bird a touch of fancyness ...I'm gonna use this tray instead of the one I 've allready made out of ply and carbon sheet sandwich....I know it's a bit "tarty" being transparent blue n'so but what the heck... I like it .

[MCMF]

Two larger tanks of the "Cat" that felt the need of some extra reinforcement on their circumference due to a deforming while refuelling and while extracting the fuel out...so some fine carbon ribbon was added .

[MCMF]

Preparation of fuselage to wing wiring steps...

A. Soldering of extension wires to a D-Type 15 SN connector.

B. Runnig the bundle through protective mesh sleeve.

[MCMF]

Next was running the previous prapared wire extensions through the fuselage..

[MCMF]

Finally fuselage halves been joined...

[MDreamer]

Wow. that's insane!
we are waiting for the next project.. i think i see something in the background

אז תגיד שאתה בונה סירה , רמזים , חלקי תמונות , השארת אותנו במתח

אין ספק , אם כבר סילון יש חבורה שבעיני היא מנצחת ,

סקייהוק , פאנטום , F14 וכל השאר סתם טיסנים
אולי זה קשור לגיל/לילדות (למה נחשפת כילד / על מה חלמת )

אישית אחרי כל כך הרבה עבודה הייתי רועד להטיס כזה דבר , אבל בטח שאשמח
לצפות בכלי טיס הזה באוויר .

אין דברים כאלו , תודה על השיתוף.

אילן .
