Default Change of covering on my Badius...

OK ... as many know - I have the Accipiter Badius mini pattern Ship from Banggood - the older all foam version of the one on Hobby King.

It was supplied without decals ... as a plain white ARF kit. I covered in HK film - but even though looks OK for flight - never really been happy with it. But for others - it proved film could be used on bare foam.

I am now going to remove all film and replace with a more traditional style covering ... silk and PVA.

This will create a skin and give me a surface resistant to damage .... plus a 'canvas' to do my own colour scheme. Yes - to use my airbrush again !

So as she is now :



Start the stripping of film :



Fuselage stripped - needs cleaning up a touch and removal of tail feathers :



Tail feathers cut out ... wing uncovered ... :




I've also decided that I will try make her a trike U/C with a Stinger nose wheel set-up and mains set back a touch.
Will continue ..

The silk is synthetic from local dressmakers .... used for light backing to dresses / window net etc. Close weave and extremely light but strong. $3 for 1m x 3m. PVA is standard wood white PVA glue mixed about 70% PVA and 30% water.



First is one side of fuselage ... hopefully fuselage can be completed with a single wrap around piece avoiding joins except underneath.



Then wing but this time done in two pieces .. bottom first :



Tail feathers are done also one side at a time ...

They will dry overnight and get next parts covered tmrw. Once all dry - then its sand the joints ... maybe add another coat of PVA mix if weave needs more filling.

Tip - Forget Scissors for this stuff ... unless they are very good quality and SHARP ! Best is to cut with sharp new blade in model knife.

Carrying on ...

Trim round all edges - clear the glueing areas and apply other sides material ...











Now wait till later to work on completing the lay-up and then decide on colour scheme.

Covering of course does not tighten as in doped old style ... so there are ridges / areas that are not so level.

This will be sanded and then overcoated with another PVA / Water mix to fill / resolve.

Overall she's looking OK and a good resistant skin has formed.

I'm toying with idea to let wife loose with Airbrush ... see what she comes up with !! once all dry and ready for paint.

Nigel: I'm kinda waiting to see how it comes out. I recently used plain copier paper that I just tacked the edges down with about the same mixture, then allowed to dry overnight. Then I sprayed it with Windex and used low heat and it would shrink up quite nicely. It was on an open framework of ribs, but it should work on foam, guess I'll see what you come out with, but I don't like sanding dried glue. Marty

Looking good Nigel. My one and only foamie is a Multiplex FunJet that I started covering with 1 oz (if I remember right) fiberglass and WBPU. It worked pretty well for me. As for filling the weave I used high fill auto primer and wet sanded between coats. I got the vertical fins smoother than a baby butt. Problem is I lost interest and went on to who knows how many other builds. So far only the fins are ready for paint. I haven't even primed/filled the rest of the plane. Maybe one of these days....

Pink ... not really my colour !!

Anyway ...

So all started top put back together ...

First install landing gear mod ..



Check out wing fit ..


Spray up in multi freehand colours ...







Rudder was left of and will be hinged once paint dry ... and sprayed as well.

I have noticed that the silk in places needed more fill of the weave ... I'm hoping that the paint once set - will provide a better base that next coat on top can be OK ...
She will be receiving further coats but not so much to create a glossy plastic model !

Overall ? fairly pleased ... what would I change ?

It needs a better adhesive to tack the edges as the PVA is slow to hold the edges and some have lifted ...

BUT - the overall skinning effect of the foam is well worth it.

The landing gear change has corrected the tail-heavy moment she had very nicely and is a change I would recc'd.
