a plan in PDF file format can be tiled so it may be printed out on a normal printer as A4 pages and then taped together.parts plan taped together and laid out on depron

Hey Joe,
Very nice ! Sound like a good size at nearly 120%...
Don't forget to cut 6x6mm Depron strips to reinforce the gluing / model.
What power setup have you plan to use ? I cannot remember... :oops:
Fred
-
Hi Guys. Could that model just be made as a PSS model or is it to small to do so.
-
I've made the f15 as a PSS (enlarged at 150%).
Fully made with 6mm depron... Wayyyy too light ! :D
The flight was great with loads of ballast, but a bit limit for the structure... Much more like a beginner plane. :wink:
So, for me, I'll do the same, but using 4 mm balsa for the body and 6mm balsa for the wings. And I'm sure that will do a great looking PSS !
I have a picture of this PSS.. I'll try to find it and post it here...

Found it ! :D

Looks Cool. Whats that DG in the back ground. It looks like it could be a DG 100 or 200. Is the plan you can download from the mount Lenister site for the F-15 already blow up to that size or do you have to do it yourself.
-
Dammit. The Mount Lenister site is not working. It was working yesterday. Now I can't download the F-15 plan :cry: .

Hey Alan,
Yep, your right, It's a DG100. It's Patrick's glider. You can have more pictures in the gliderireland website. Very light model. Fiberglass fuselage and structural wings.
For the plan I have it at 100%, 120%, 150 % but basically any size.
I'm at home now, but I have the plan with me. Let me know witch size you want and I'll send you the pdf file.
Or Joe can send you the plan aswell.
Fred

The 150% size would be great, the bigger the better. I'm not sure when I will have time to build it, but it would be great to have it on file. My email address is in button below, I hope. Much appreciated.

Alan, You have a mail !
:D
Happy St Patrick's day !! :D

Thanks Fred. :D

Your welcome Alan !
Joe, the building is looking great so far !
You have to think of a paint scheme now ! :D
I've removed the link from the website on monday.
I'll put it back when you want.

ok here we go a bit more work done on the F-15
front and rear fuse sections together.center fuse fin is mounted.this holds motor mount,servo for elevator and the elevator control rod passes trough it.after lots of checking, holes were drilled and the elevator control rod was fitted.left elevator was glued on and control horns were positioned on the rod but not glued,yet!.servos were fitted.they were a push in fit, helped with a little glue for security.controls set up for elevator.motor,mount and mounting stick glued into position.

(http://homepage.mac.com/josephdoyle/rc/_img/f15/f15rear.jpg)
only problem is i don't think i have a folding prop of the right size.they all seem to be too big and will pull too much amps for the motor,esc,battery i have.will find something that works for a test flight!
not sure yet about a colour scheme.was thinking the usual grey military look.now i'm thinking a high visability scheme might be nice.blue or red.am prefering the red so far

more coming soon
actually liking the blue better now that i've looked at them together!
i think blue with the layout of the red scheme
-
Hi Joe,
My vote goes to the Blue one !
Great one, and certainly rare !..
Or a Tiger Meet scheme... :wink:
Fred
-
Yes the blue looks great :D .
-
So Joe, I think that's it ! " Le peuple a parlé !" :D
Go buy some blue and some aluminium paint !
Fred :)
-
blue it is then
right!. better go and finish the thing first!
-
Stop spending your time on the Internet !
Go back to work on your planes ! :D
Fred

brief test flight.was a bit windy.will try again tomorrow
this thing flys pretty good!.or should i say will fly pretty good.launch was uneventful.got someone to launch it over their head and away it went!.
first thing was it wanted to go straight up.trimmed it to fly level but,when full throttle is givin it wants to climb.so i have a thurst angle problem.it also wants to bank right with throttle.again a thrust issue.can be fixed by mixing elevator and aileron with throttle or by adjusting the thrust angle itself.will probably do both,using the mixing for fine tuning.
the power set-up seems to work well and its pretty quick in the air.
6x5.5 apc prop on a prop saver
mega 16/15/4 .not ideal.this motor works better with a gearbox swinging a big prop.which is what is was being used for.16/15/3 would be better
Jeti 40 ESC
3 Cell Hyperion LightStorm Lipo 20-30C. lots more power than older version (same as new Polyquest XP)
used P-Calchttp://brantuas.com/ezcalc/dma1.asp to work out power set-ups.amps, watts ,thrust ,efficiency.it's pretty good ballpark figure.
here's what it says for the above.kokam 2000 mah battery substituted for the hyperion(they don't have the hyperion)
(http://homepage.mac.com/josephdoyle/rc/_img/f15/f15motorsetup.jpg)
will fly again tomorrow weather permitting.hope to get video too
-
got some painting done.all the white bits will be light blue/gray like the nose.need some dark paint for the canopy and rear turbines.probably do an inverted version of the top on the bottom.

Hi Joe. Looks great :D . Is that one of those computer programs that gives you an idea of what motor, prop, battery and gear box to chose for your model. Whats it called?

Hey Joe,
Just saw the video !
Very nice, and your mate was not sooooo drunk ! :D
Nice flight, and nice music... Ok, joking here... :D
Alan, your Pb may come from Quicktime. Reinstall it, and that should be fine.
