Hi Rich (E) and Steve,

Thanks, you've sold me. I'll certainly keep my eyes open for dates and locations.

Cheers

Mike

I managed to sneak up the field yesterday for my first flight of the year where I tested the new head plate cut for me by Malcolm. The results were excellent, so much so that I felt comfortable enough to fly it close in keeping pretty much within the out skirts of the patch.

I then switched to a two blade set up which required 3 degrees extra rearward tilt, a little extra nose weight with the throws reduced to 40%. It did fly but was a little pitchy, I will probably switch to a different aerofoil and add a little extra nose weight when I get chance to get to the field next.

I managed to grab some footage of a couple of flights, the final 3 blade set up first followed by the 2 blade set up.

Enjoy
Rich

G' Day Rich . My compliments on your newest project give my best to Deb'ssmiley and the model looks pretty good also. Looks a very nice clean flying machine ....must try the two blade version.

Happy Landings

Chris...

Nice one Rich, 3 blade looks great.

2 blade setup still WIP... think strong bike clips required for us mortals.

You will have it sorted I am sure then a 2 blade setup would be lovely in the air with the characteristic blade slap. Of my 2 RPGs the 2 blade is by far my favourite!!

Nice one Rich. Obviously no problem with the new 3 blade head. Seems to fly smoothly. May try one of the new plates and see how it compares with my set up

That looks really well dialled in on the three blades.

We're those your old Rex blades used on the two blade setup ?

Graham,

I would appreciate your thoughts on the final triangle once you have tried it?

Rich,

Yes, the very blades! bit old and tattered but still working OK, will be trying a slightly different profile with a wider cord. Obviously a tad more nose weight is needed but its not far off.

So over the winter I pondered the flight characteristics of my original large Revolver. Look great in the air but a bit floaty on the large Gemini blades.

I decided to try the 6mm blades cut down a bit. Yep flys but inconsistent. Maybe blade flex ??

Plan C was 9mm blades for stiffness but shorter.

Bingo, flew yesterday and perfect, great lift , good spin up and much better forward speed without being excessive. Great thing about these it's trial en error

Finished front

The definition of Design Steve is " trial and error "

Can't wait for this one thanks

Denis Watkins,

I hear you on that but I'm rather impatient and really am climbing the walls to see hopefully the Revolver 2 in RCM+E as have always had a fascination with autogyros! I mean it is an absolute credit to it prolific designer Rich Harris

Kindest Regards All

Well, my Ajay has just bit the dust so keen to move on to a pusher. Any sign of this ever appearing in the mag?

Gavin,

Sorry for the delay in replying, yes the Revolver II is planned as a future plan in the not so distant future.

One of the issues that was hindering us was the unavailable HK C30 head, this has now been resolved with a readily available head designed and produced in the UK by Coolwind HERE, they will also be supplying the triangular head plates and any GF parts needed for this specific model for those who don't fancy making them.

I have now had confirmation that my Revolver II will be published in the May edition, I will add a full list of what is needed nearer the time.

Friend and fellow Gyronut Chris from down under has completed the fourth test model, he went a different way and carved his from foam then glassed it. I believe it has been a bit warm but he has flown it now, I'm hoping he will find the time to make a flight video in due course.

A photo of his example, note the cowl !

As promised a rough list of building materials for the up coming Revolver II, all of the balsa sheet is of medium grade. If you are able to select the blade balsa and spruce so that its density and weight is as close match.

I will add the GF sheet needed but Malcolm at Coolwind models has kindly agreed to supplying all of these parts CNC cut as well as the sintered 3d printed head. Also available will be free files to a 3D printed head unit, these will be on Coolwinds 'download' page, a friend has printed these for me so I will post how it goes together in the coming month as there are bearings etc that will needed to be sourced to complete.

Construction Materials

1 off : 3mm x 102 x 915 balsa sheet

4 off : 6mm x 102 x 915 balsa sheet

1 off: 3mm x 300 x 600 Lite Ply sheet

2 off : 6 x 13 x 915mm spruce strip (1/4" x 1/2" in old money)

3 off : 6 x 10 x 915mm spruce strip (1/4" x 3/8"

1 off: length of 10SWG piano wire

1 off : 3.2mm x 13mm TE section

1 off: 6mm thick sheet of depron

1 off: 0.4mm thick Fibre Glass sheet

1 off: 0.8mm thick fibre glass sheet

1 off: 1.5mm thick fibre glass sheet

The rest is block wood and small pieces that I presume most will have knocking around in their scrap box.

If I think of anything I have missed I will add

The 3D printed head is explained by its designer in the video below starting from 1.27

Rich,

Only just seen the most recent few posts. Looking forward to the mag coming out this week. I need something to get the juices flowing again after moving house and moving away from both of my Lincolnshire clubs and the excellent flying fields there. Struggling to find a decent club/field near me.

I bought a job lot of the HK heads a couple of years ago. Could I use one of these or would you suggest the head from Coolwind, which do actually look much smarter!

Gavin,

The 3 test models on in the UK have all used the blue HK head consistently over the last few years so we know they work well. It was only because they have dried up over the last 12 months that Malcolm decided to designed his own taking the opportunity to improved upon the original. All of the hole centres match so if anyone does break their HK unit the plates will transfer over onto the Razer unit. Generally it's the front arm that goes on the HK head, Steve Jones modifies this part on his from aluminium I believe.

I hope you find a new field to fly and that you have a go at the Revolver smiley

Yes mine uses the HK head as with many of my small models - absolutely fine but the weak link is the forward arm as it has minimum section due to all the drilled holes. Flying loads are not the issue but a tip over on takeoff or landing normally snaps it like a carrot.

Not being a machinist I thought there must be a way and with aluminium strip from ebay and a pillar drill and hacksaw a much stronger arm can be made in 5 mins which bolts straight on... I will post a pic.

This model is probably my most flown and still my 'Go too !! '

Some pics from just last Sunday cheeky

Good news, Malcolm @ Coolwind has now added all of the CNC cut FG parts for those who don't fancy tackling them.

They are located HERE
