Thank's guys... Here is a continue...
In meanwhile, I buy Jet Cat P 80. It is new engine and it arrive to me from Lindinger Hobby shop in Austria. Because my country is not in European Union, Jet Cat engine in Austria was export product so, I get 20% down price...
We have here grass airfield so, I need this part...
All gear doors I made from thin (0,3 mm) aluminium plates. It is easy, easy to cut and make them shape.
Steve from Bobs Hobby Center buy in Sierra for me UP 2 retract valve and two small air cilinders. I use them for main gear doors...
Front gear door I made from alu plate also, and use servo to operate it...
I know that Panther have two doors, but...
Hitec servo 645 MG is for front wheel...
For better holding in close position, little magnet was add... You can see it in the middle of a door... On rear doors it is in front corner...
Glass was add on all parts...
...so now I put filler to see where I need to made a little repears...
Before adding panel lines, first want to put all stuff in fuselage...
I have two one liter gas tanks, UAT, all jet parts, air valve. servos, batterie...
In front of the plastic intakes I place one tank above other. All what I do in these phase of building need to be easy to assemble and disassemble...
Upper tank will stay in place with velcro strpips...
In front tunnel, in fuselage I made bracket for batteries. Li Po batterie for Jet Cat Ecu must always remove for charging, so bracket for it is with angle for easy operation.
In right side of tunnel is inaf space for lead, if model need it for CG.
I was trying to add in front all heavy parts, so on the botom of the right side fuselage, next front wheel is servo and air valve.
Above that is plate which carry pneumatic tank, ECU and fuel pump. Plate was made from light, 3 mm, plywood...
Air tank and ECU will stay in position with velcro also...
On the right side of the fuselage, I made place for propane gas tank... In front of it on the side of fuselage electronic valve and filter. Filter is in vertical position and it is not niggardly set, because Jet Cat manual wright to set that part in position like that. In that case no any air bubble can stay in filter...
On the top of propane gas tank is quick coupling, which Jet Cat add with engine... Festo can be good also...
Left side of fuselage, near gas tanks, is place for UAT, which is also in position according to user...
On the top of fuselage, I make plate for receiver, switchers, air valve... First must made bracket...
When this stage was finish, I take out all this parts and want to star adding panel lines. But first, want to check how ailerons, flaps and other parts are stand.
I was not satisfied with flap hinges, so made change like on Ziroli plan...
Before...
Last check...
...everything fit OK, ad finaly panel lines...
For panel lines first was made 1,2 mm widht strips of masking tape. I cut it on my Roland vinyl cutter...
For panel lines use few sources, plan, photos, books...
...and add lines...
Next was filler...
...and after taking 1,2 mm lines from surface result was grate...
Next step was adding rivets. For that I use soldering iron and metal template, which is made from saw blade...
Need one week to add rivets on all surface...
When press pick of soldering iron on surface it look like this...
...but after light sanding...
...it look grate.
Few more details on wings...
...and fuselage.
You need to add three to four layers of filler, to get thickness for surface like on photos. But, it is interestint to note, that after adding filler for panel lines, rivets and light sanding at the end of that process, Panther is just approximately 300 gr more heavy.
On this weight, you need to add paint, but paint apply in thinner layer, so I think all finish will not to be more than 500-600 gr.
Rivets on metal parts (gear doors) I made from little circles, made from vinyl tape.
Last process before paintig, was to add details on Panthers surface. For that I use Oracal 641 self adhesive foil. I put one layer on other, so like that I get required thickness.
Because layer is now thicker, on Roland vinyl cutter you need to add more force for cutting, and every part must cut three times.
After that process, it is easy to separate detail parts...
I use silver tape for this process...
Few details in close look...
In next ten days I hope that model will be paint...
Until than, best regards
Mirce
