Hi Guys,

Here is a short Video of Taiwan's Mr O flying the glass wing prototype Redshift. As you can see its a bit bendy but not bad for an all glass plane.

The carbon versions, type 1, 2 and 3 are CONSIDERABLY stiffer!

Yeah the UK team has picked some interesting colors.
Yeah...someone locally described it as (Translated) "Horse Pr*cK Pink" Hmm...But in fact it does grow on you.

Well, no accounting for taste though pink would NOT have been my first choice for a base colour.

Doing a couple in the "Alternative" scheme.

Cheers,

J.

First flights for the UK team last weekend. Unfortunately the wind speed was only 2, or 3M/sec so the competition was cancelled. But as you can see that even in this tiny breath of air, the Redshift still flew very well.

Words from Top UK pilot and Redshift F3f Team member:

"Loving the airframe - design, colours, flight attributes....it represents such a different approach to F3F. Very impressed with the straight line speed, tracking and responsiveness. As we predicted, its caused a bit of a stir within the UK F3F community, and that was in 2.5 - 3m/s wind speed!"

Other UK team members John Philips and Mark Passigham's planes should take to the air this coming weekend - if the weather permits. Last weekend's video can be seen here:

Cheers, and see you soon!

Hi Guys - more Redshift news from John Phillips:

Hello Jim

Well, Greg and I managed a good result on Sunday with the Redshifts, there first competitive outing in the UK. Greg was 6th and I was 5th.

Greg was fastest in two rounds and me one out of the nine flown  Only a point or two apart, the plane shows a lot of potential and make a fantastic noise when moving at speed. I’m sure Greg is off the same opinion.

I intend to fly the Redshift as my number one plane this year in the UK, as to the European/world cups not so sure it will work in the lighter air we tend to have there, but it will be with me so could happen

Still more to come from this plane, it’s different in looks but I feel the wing is right.

You don’t want to change the look of the plane, just the handling, the main thing is to keep the noise it makes 

Doc, I'm by no means second guessing your design philosophy.
But doesn't form (looks) follow function in aerodynamics (fluid flow)?

Keep the noise? Isn't one of the indication of a clean design the level noise or lack there of?

Wow, you guys are that attuned to the ships that you can tell which is which in the air by their sound?

With a tin ear,
Konrad

Hi Konrad, the Redshift uses a new wing design which concentrates on trying to manage the airflow. This means that I wanted to know pretty much whats happening with any of it when its traveling at competition speeds.

A few things came out of the study.

1. There is no substitute for aspect ratio if you want a fast sailplane.
2. The planform makes a lot more difference than people might think.
3. You don't want moving control surfaces close to the wing tips. YES the further out they go, the more effective they become. But the wingtips are where most of our trouble starts on sailplanes, and the more you disturb them, the greater the chance of that trouble occurring. I wanted to keep them clean.
4. I want the vortices concentrated where I know where they are, and where they can hopefully be controlled by the wing shape and the tip profiles. What I don't want is a ragged shedding of the boundary layer here, there, and everywhere - even if it is quieter.

If the planform works - with the wing getting to high speeds, then the vortices will be there at high pressure and they will be noisy.

The Redshift has a strange kind of noise ONLY at high speed and I call it a "Twistle"

The Redshift makes a very special noise - its quite unlike anything you have heard.

Come along for the flying and bring your ears!

Cheers,

Doc.

Congrats to Aeroic Racing Team John Philips for his 4th place sat the Eurotour Northern Open (UK) at the weekend.

Conditions were a bit scrappy and as usual the international field was strong.

Memories - the first USA Maiden of the Redshift F3x at Tick Point.

Wayne on the sticks, here conferring with Bruce prior to the first sortie.

Perfect wind, lovely sunshine, killer view, great friends - What a day!

And by the way - happy birthday, Wayne!

Huge Congrats to John Phillips flying the Redshift in the English open last weekend where he garnered fastest time:

As John puts it:

"39.22 in thermic air, open style turns as best I could...fast plane"
