I know Mark is flying the prototype more and will shortly get a new one to test following some more improvements in the layup and mechanicals.

Here are a few pics of the second prototype thats headed for Marks cpable hands on Tony Fu's QC bench.http://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-98490700-1335659393.jpghttp://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-19738300-1335659396.jpghttp://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-23728100-1335659489.jpghttp://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-97038500-1335659490.jpghttp://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-17191300-1335659492.jpghttp://www.barcs.co.uk/forums/uploads/monthly_04_2012/post-2066-0-90349200-1335659492.jpg

Perhaps I'll get a chance to video it next time the wind is blowing from the NW :)

Hi All,

some more flying with the Schwing - this time on a coastal site. Windspeed approx 20mph, flying weight 2.5kg.

Video here

Best day flying I've had for a long time! I'll add a couple more videos later too.

Mark

[Mr Ed]

VERY impressive!

_{Another for you from yesterday's flying}

_Enjoy!

Cool, Needle 100 competition? :cool:

[Mr Ed]

Not without an F3F legal nose. :-)

Darn pretty and looks as fast as a fast thing though.

[isoaritfirst]

Looking well sorted Mark..

[mark_r]

Liking this model more and more Mike - the small size (compared with my usual 3m stuff) makes it an ideal go anywhere model, but with the feel of the bigger stuff. Rock solid too for F3F type practice!

Superb Mark - will it be your No.1 model for Rugen

Model looks great, turn style excellent. The lower ones are quicker I reckon.

[f3fman]

Looks great, are you sure you haven't squeezed a turbine into it ! ;)

[hambone]

Fins copied of a certain popularChinese model I reckon...Emoji not working here

Wonder who designed said "popular Chinese Model?" :-)

[f3fman]

I expect he drew around a Sigma fuselage, I think I still have a couple in my model storage room ;)

Hi James,

Ref the thread on RCMF about "live airfoils" and your reply "However, how many people use UP and DOWN when programming thier snap flap?"

Lots of us have been doing just that for quite some time with airfoils that were designed for that application such as the TP42 and MG05.

Granted these are symmetrical aerobatic airfoils, but my elevator to flapperon mix for camber and reflex is permanently on, and there is a noticeable difference if it is turned off.

So I'm guessing you've designed an airfoil with similar characteristics in being highly sensitive to camber changes.

(sorry couldn't post this on RCMF-been a naughty boy on a temporary ban!)

MG06 as well

and the whole "4-axis" thing

nothing new here

nothing wrong either - airfoil designed for camber change is a good thing

Thats the one mate!

I know four axis flying is not quite what James is talking about, but with a wing that is quite sensitive to camber/reflex changes it can add an extra dimension.

interesting link on there to:

http://pierre.rondel.free.fr/4axes.htm

(run it through google translate)

1998 page - Marcel Guwang (MGxx) discussing airfoils for "4-axis" (constant camber change) - with a mention of Quabeck - which resulted in the "double cusped" MG05 on the Voltij - and the "cusped" (reflexed) MG06 on the Miraj & others - MG05 subsequently improved into TP42, and cusped/reflexed/designed-for-camber-change aerfoils further developed for F3B/F3F - all good development that we can benefit from
