Slope Soaring / Quark 2M - Back to cutting innocent trees!

« on: May 31, 2013, 15:47:39 PM »

Thanks for the kind comments!

Eventually got the machine covered - film courtesy of Mr Cod - seems like good stuff for the price. I've covered the underside in white with the intention of putting big dark blocks of colour on.
Pix attached, always was a frustrated PSS'r  :lol:

With any luck, should get it out on the slope this weekend.

Much prefer the idea of a wood spar - aircraft spruce is much cheaper than carbon tube !

Cheers

Slope Soaring / Quark 2M - Back to cutting innocent trees!

Hi All

Thought I'd post yet another Quark - this time from across in Scotland  

I'm lucky in having my own homebrew laser, so cutting wasn't an issue  

Used liteply for the fuselage sides rather than 5mm balsa, so I'll see how much lead is needed in the nose :-)

Only had a couple of minor structural issues during the build, the servo plates were only attached front and rear on the formers - consequently, they were really weak at the servo cutout and just cracked when installing the screws (there was also a lot of flex when the servo operated). I changed the design to have the servo plates the same width as the fuzz - also stops the fuselage flexing where it's gripped. The other one was the vertical stab, the top half of the stab is held only by a couple of small areas of horizontal grain - I added a 6mm spruce spar at the fin TE which ties in to the end of the fuzz.

AUW is around 960g naked - I'll post some more pics when covered.

Great looking plane - thanks for making it available - good job!!

BTW, anyone struggling to get carbon tube etc in the UK - I got mine online from Woolmer Forest Composites ...

Not cheap, but nicely made and well packed - real pultruded too - not black chinese dust and epoxy :-)

Cheers
