Well the gear seems to work fine so far, with the new wheels. Actually, they are not that bad. The aluminum does not bend (yet).

I am not as good as others at anticipating all the things that will eventually go wrong ... I just fix it as I go along ..

That's why all my jets are a work in progress


Yesterday I took a short video of Gregg F flying the F-86,

Good to hear, I really like your Sabre.

I'm itching to build one of these foamies for some reason, go figure. I haven't built an airplane in almost two years and haven't flown much in the last year either (did 3 events and maybe flew 12 times all year) and suddenly I'm into it again. Built the Yellow F-4 as well as a little Kyosho F-16 and a Multiplex Twister. Got about 10 flights in on the foamies in the last two weeks and now winter is here with a vengence . 20's and mondo wind today.

Anyway, the F-4 foamy looks good and the Mirage also. Like the Sabre but I've got a BVM 90% built on the shelf I ought to finish first...

Hey Chris at some point I thought of doing the Mirage, that thing is even better than the F-86 (the problem with the F-86 is that it is BIG).

But with two Rafales, I thought I pass on another Dassault delta

Here's a video for you which I think will convince you to get that Mirage as a lazy weekend flyer

It's Kevin Saunders (of JePe Pyranha fame) flying the Mirage at Bickley, unbelievable performance, fully glassed yet very light airframe with JePe 8S (or 9S?) Midifan setup with some el chepo lipos. And retracts with fully functional doors

Heavier flys better ... yeah right

LOL! Lazy weekend flyer <g>. I had seen that, it is enticing. I've got a stack of 2,650 40C packs on order for my Twister. I've also got a Schubi with a Hacker B50-13XL (more than 1 actually) on the shelf without a home. Might have to match them up .

There you go ... nothing better than an un-employed DS-51

Sunday night I made a few more decals for the F-86...

I printed them on paper in the right size, taped them over a monokote trim sheet, and then proceeded to patiently cut them out with an exacto knife.

Very nice, impressive patience . What / how did you do the panel lines - pen or tape? How did you scale up the markings on the computer, is it a drawing or a font?

Chris, for the thicker lines, I use Great Planes striping tape,

http://www3.towerhobbies.com/cgi-bin...&I=LXJ889&P=ML

it streches a bit more than the Carl Goldberg one, and works very well. They have various colors and widths at my LHS.

The thinner lines I do with a sharpie pen from target and a flexible ruler,

For the wing markings, I got from the internet these "Amarillo USAF" fonts, and used them in an MS Word document.

To start, you unzip the file containing the USAF font, and put the font in your c:/windows/font directory. Now it can be used from any Word document.

I then printed the stuff out on regular paper (couple of tries to get the size right), taped them to a monokote trim sheet, and cut them out with an exacto.

I cut out all the markings Sunday night while my wife was watching desperate housewifes, cutting did not take mor than an hour

I laid them on the fuse and wings with plenty of soapy water to get the alignment right.

Thanks, I knew about the Amarillo font. I had it on my machine @ some point. Maybe was the last machine because it is gone now. The "Minute Man" was what I was wondering about specifically.

... as far as detailing is concerned, I think I'll stop here for a while

Had two more flights yesterday, only small problem left is the leaky fill valve. Retracts & flyfly struts now hold up well.

Best flown with large majestic easy manouvers

I've had 12 flights on mine, and the FlyFly stock LG is holding up fine, after doing the various mods discussed before (new hard steel pins, trailing link redone, new wheels).

I managed to find some time to work on the landing gear. Initially I thought of putting in gear doors, but after doeing the whole installation I found they would not operate reliably.

The main inner doors would not shut 100% consistently, and the outre geardoors would flutter in flight.

So I removed all of the gear door stuff (kiss principle), and instead made the gear openings smaller:

So far the main mods to the included flyfly gear are :

(1) replace the flimsy plastic wheels !

(2) replace the soft steel pins with quality steel piano wire

(3) fix the trailing link connection with a screw

Now the gear works fine on grass ...

After flying the Sabre with the bigger 9S 4Ah 40C batteries (2900W) I have added a small graphics card fan to keep temps on the
esc (Hobbywing $99 100A 12S HV) down.

I still have to add two zipties to keep it secure.

No point (so far) of butchering the intake, and as it's installed it can easily be exchanged without ripping the fan & ducting out

Hello Dutch Master ,

Here are a couple of pictures of how I did the ply ducting, it has an intake diameter of about 87mm (width) x 75mm (height) or 51.2 sq dm.

One advantage of the ply ducting is that it is very stiff and supports the batteries well (9S 4Ah), but I do have a heavier motor (Neu 1515/1.5y, 360g) at the back which helps the CG.
