P51D - EPP PSS
Fred:
So, here we go again, but this time with something a bit more relaxing ! :D
I can't really stay long without building something, so this time, that will be a PSS !
This is a 1.20 mtrs full EPP PSS kit that we are selling at the shop (www.islandmodels.ie for those who don't know ! :P )..
Today, the baby left me free for 1 hour... Perfect time to go hiding in the worksop !
The kit :
First thing to do, is to give the diedrhal to the wing by sanding the wing root on a sheet of paper flat on the workbench. Easier to do it than explain !
then, everything is glued with PU glue, and the parts hold in place with tape.
I'm not going to tell you how to shape EPP, just to do it outside ! :wink:
Then, just to have a look, you can put everything together for the first time (the elevator/rudder in coroplast are just slotted together)
The wing spars are made of 6mm carbone tubes. Both are glued with PU glue in the slots already cutted in the wings. They don't like together in the middle, as this part will be glued to the fuselage, and that will be strong enough !
And a strip of tape is put on it, to stay flat when the PU expand.
The ailerons are made of profiled balsa. The first job to do is to trace them on the wings, then cut it with a razor blade.
And everything is held temporarely with tape.
Well, you can put everything together again and admire the plane that is taking shape !
Fred:
The wing is then entirely covered with reinforced tape.
My plan is to primer the plane before painting... That is not going to hold long in combat, but I can do a nice scale scheme the time it will last ! :D :wink:
Next "big" job are the servos.
I'll put 3 on the plane.
2 for the ailerons, and one for the elevator (no rudder).
All the servos are standard size.
Lots of options are possible for the servos position. For my ailerons, I'm going to put the 2 servos flat on the top of the wing in the fuselage. Luckily enough, the 2 servos together are the exact width of the fuselage !
A bit of prep work, and you can start cutting !
The servos are then glued with cyano glue.
And that's it for today ! From the first cut to this stage, I spend 1 hour...
Tomorrow, I plan to do the elevator and to finish the covering !
IceWind:
Fred that is looking great!
Excellent job and within 1 hour! :)
I think i wanna have one of those! :)
My day today was joining balsa and gluing it. I'll post the photos soon!
Keep up the good work.
Fred:
Thanks Fernando ! :D
Well, 1 hr is easy with this kind of model !
I think I'll need another hour to finish it.. Plus at least another one for the paint and so on... :D
And waiting for your photos ! :P :P :D
Fred:
A bit more work done yesterday evening...
Here is how to make an integrated articulation for the stab... 10 minutes of work !
First, trace the fuselage reference and the elevator on the coroplast
Cut the elevator, the perpendicular side first. I left a 2 mm gap to allow free movement once covered in tape
Now cut the elevator... The trick here is not to cut all the way through but just cut the upper "skin" of the coroplast coroplast ! Bend it several times to make it more smooth to the movement, and then, you can trim what is left of the "skin" with a razor blade.
Et voila ! No tape needed to do the hinge, and perfectly smooth elevator !
The "U" to assemble the 2 elevator is made from a scrap Bicycle spoke (I use them to do my pushrods...)
All glued with fluid cyano...
And the result :
All integrated to the elevator :D
