You cannot keep a good model down ! Polaris vers6

[solentlife]

Yep ... I've gone through 5 so far .... because they are so such a great flyer - its the sheer use of them that I have worn them out. The Depron gets a bit 'tired' ... and they start to get a bit 'ornery' at times.

So out with the 3mm Depron to make templates. Oh I forgot to add ....

I have printed up the plans so often because its difficult to keep taped tiled plans in good order. So this time .. new print ... tape up and cut into parts ... then create permanent 3mm templates.
I did this with my G&G models ... now is time for Polaris.

No need for photo run of build ... its been so many times posted ...

I will incorporate my usual personal mods ...

1. My standard split servo arrangement with servos set out in the wing for ailerons.
2. Rudder servo mounted in the fin
3. Motor and servo leads will be led down the leading edge of fin in a channel and not buried in the laminations.
4. Fin will have a vertical thin ply tongue inserted in to tie in with ply plate on wing.
5. Nose will be a Depron box with PU glue / water mix poured in to foam up and form a tough light addition.

I am also toying with idea whether to add working canards .... the Polaris is well known for its tendency to not pull out at bottom of outside loops, to need a lot of down elevator ... maybe adding canards can help by controlling the nose ?

Progress report?

[solentlife]

I've been travelling around Caspian and Middle East so only got back last night ...

She's about 30% built ...

Top view showing the extra large ply plate I use ... this is very light fruit box ply ... stiffens that area really well ...



Closer look ... its epoxied as well to create a really strong bond .. you can also just make out the channel down the front of the fin that servo and motor leads bury into ...



Underside ..



The fin is more stiff and stronger as it doesn't have the internal channel for leads ...
