Maybz - where in AZ are you? Want to borrow something to fly? I am in Gilbert and have an extra just about everything laying around but no MDC F-14 yet.
SS and bird dog with lights, Sunday, Samba, BL Electristar, 63" Cadet... Just let me know. I am sending a PM with my cell #.
(man must fly in weather like this)

Hey All,

For my wing pivots I used cut sections of an aerosol can lid, specifically I cut rings from the butane gas soldering iron refill cans lid to make bushes with.
They only need to be 5mm high and then I epoxied them around the circular wing pivot pieces, the hard plastic seems to act as a very nice bearing so far.
I didn't take any pictures to post here but hopefully you get the idea I used.

For wing lubrication I sanded both the wings and the areas on the various decking parts which would touch before I added clear selotape as a bearing material. This increased the tolerancing between wing and panels slightly so as not to add any excess drag to the system.
Originally I wasn't going to add the tape, but some experiments without & with showed it does help make the wing sweep a lot smoother.

This being my first depron plane I wanted to make sure it was good from the start, but at the same time finish it to go have a play ;-)
It is a super model and looks great in the air.

Ian

Got in a quick flight today. There was about a 5-10mph breeze, but it handled it easily. Definitely a fun plane. I think cut out another set of parts so that I can have a spare....just in case.

Here's some video of the flight.

Hi all,

I couldn't help it!! Maybz, that is an impressive design indeed!! my very sincere congratulations.

When you look at that design, so clean, so nicely fitting, mmmm... to those who haven't tried to design/draw plans for a beast like this it may seem so easy; but my friends, don't you be mistaken, behind this F-14, there are many hours of tough work! Once again nice work, keep it up!

Anyway, as I said, I couldnt help it, had to have it!

So here are a couple of pics of the cutting process in my cnc hot wire cutter driven by the CeNeCe PRO 1.10:





as you can see, pieces can be placed very close to one another, there are places with 1mm or less spacing!



This is what you get after a couple of hours of doing something else or staring at the cutter :-)



Can't wait to start building!

happy landings!

Dani

ps:choza, what happened to yours??

I just found this thread this bird looks amazing….
I only have one thing to say “WOW”

I just few questions what program did you use to design this F-14?
Are you going to sell this as a kit or should I go out and buy laser cutter?

I finally got a few pic of the Vac table jig I made for doing Mike's YF-23.

It'll come in handy for other things as well.

I'm simply powering with my shopvac for the time being.

It's made from 1/4" Sintra PVC sheet and 2" Blue Foam !
I grooved the blue foam to 1 1/2" depth plus an port to
manifold to all the grooves.

I made a single set of YF-23 parts with it and they came out pretty nice.

The idea that MIke had was to place grooves part way thru the depron
right where the bend lines are in his design.
I needed to be able to hold the sheet down FLAT ( all over) , to do this,
hence the VAC fixture.

This will be another great design by maybz for DF or pusher prop !

The bad thing is that it'll require twice the operations to do this since
my machine does NOT have an automatic tool changer.
That'd be ME ! ( ol automatic bob )
So I'll have to cut the sheets then change bits and then
do the grooves.

Hey Maybz,
A very greatful Thank You for sharing this project with us. I appreciate all the work you've done. You couldn't have made it easier for someone to understand and build. Only took a day to cut and assemble. Woulda been faster with one of those awesome CNC cutters, those things are neat!

The finish weight of mine is currently at 13.6oz w/TP 1320 11.1v and one of those H/L XT400 Esskay motors. If that doesn't push it then she'll get a Jet Screamers on her back. It's just about ready for paint and that'll push the weight up an Oz.

I cut enough parts for a second build and that one is goin' to get fans and maybe ailerons.

Thanks again and Happy New Year!!

I have a couple of the small GWS fans. Think they are 40mm? They just about slide into the ducts so it shouldn't take much moddin'.
I just picked up two 5300kv 12mm BL motors and if the fans give at least 7oz of thrust each (which should be easy enough) then I'll be in business. Seems I remember runnin' up one of those fans on a smaller Kv motor and got close to that amount of thrust.
