Quark 2M - Back to cutting innocent trees!
Guysie123:
Hi Fred, I’m new to this forum and building the Quark, lovely kit by the way!
Quick question, what are these wing profiles for? They’re the same profile as wing tips N11 but unnumbered and full span in length.
Any advice would be much appreciated.
Thanks, Guy

1590 grams, can’t wait to fly it!
Great kit Fred and everything fitted together very nicely.
Detachable tail to help with the transportation.
Might make a second nose at some point with motor as an electric conversion.
C of G is currently 79mm from LE at root, does that feel about right?
Any advice on CG position from anyone would be greatly appreciated.
Thanks

Hi Guy,
Sorry for the delayed reply!
Your Quark looks fantastic! Looks like the V4 no?
For the CofG, correct, 79mm from LE is what everybody agree on. You can go either way from that point 10mm back or forward without too much problems.
Anyway, Quark is really looking good! Wish you all the best for the first flight, and hopefully, a lot of fun! :)
Keep us posted of course :)
Fred
Guysie123:
Hi Fred, yes it’s the V4 and really enjoyed building the kit.
Many thanks for the CG info, very grateful.
Keeping fingers crossed for some good flying weather in May, looking forward to throwing it off the slopes! The South Downs near Eastbourne (England) is our usual spot with a good variety for most wind directions.
Will keep you posted.
Best
Guy

Hi there!
Finally, I was able to maiden my Quark at Mt Salève, France near Switzerland, with a 15-20 kmh wind. It flies awesome and easy, thank you Fred!!
Weighs approx 1400g with 5 nimh 2000 mah and 100g lead. Needs a bit more wind than my ahi, but the inertia difference is so cool!
I just need to complete the covering with a more flashy extrados.
Now waiting for the next flights, maybe Belle-ile en mer, Bretagne, France.
Bye.
