DH Cirrus/Gypsy Project

yes its kinda depending on the type of profile but the profile we will be using is a little hollow and will be fine with 1+ for both top and bottom wing and the stab at 0.

 

With this type of profile you would not see or feel much differance when you go for a +1 lower wing and a 0 lower wing which should give a later stall for the top wing.

Hi Danny and Ton,

 

Nice project you're doing here! Ton will draw me a DH-83 Fox Moth, so the wings and tail can be copied.

(little explanation: I'm a modelling collegue/friend of Ton, flying on the same field. We usually help each other with our projects )

Hi Jitze,

 

The Fox Moth doc is comming nice together did find a nice 3view so looks promissing.

 

Ton

Danny ,

 

No progress yet still waiting for the 3view hoping it will get here soon.

 

Ton

The Fox Moth 3 view by Roy Tassel at 1/48 scale is in RC Scale Aircraft Dec / Jan 1993 together with the article for Malcolm Hardings 59 inch span Fox Moth plan no RSQ 1700.

 

The same 3 view was avail at 1/36 scale from Roy Tasssel at that time.

 

 

Danny. I have the magazine mentioned above............

kc,

 

must check not sure but I think that I have that 3View already including the article,

what I really need are cross sections.

 

 

Danny,

 

Good news received the 3view today not super it looks like a copy from a copy but 100% better than I had untill today.

 

So looks like can have a go soon.

 

Just a question about the construction and build ; do you want a fast build with mostly cnc parts or a little modified construction as per plan you already have.

 

Ton

Hi Ton, the model is for us so you must say what you want too

Personally, I think a faster build would be nice. I am not going to go mad as I have enough long term projects. If we drop the hinged wings then I wont be overly dissapointed. I am worried about the wings though. Those ribs are so thin. The flying wires will have to be functional if we use that aerofoil. If we want to go mad then we can with the detailing. And if somebody else wants to build on without the detail then thats good too.

 

Looking forward to making all that cowling in anneled lith plate

Hi Danny,

 

Okay that's clear.

 

Have placed the drawings in cad and will make a rough check with the foto's and go from there.

 

Ton

Yes will show as much as possible will be fun to do this one in 3D.

 

Ton

 

Hi Danny,

 

Yes still keen but for the moment modelling is a little on hold.

Iam working on the bathroom and that's a lot of work, making good progress but still some work to do and its a big mess in my workshop.

 

Can do a little every now and than and did finish my Corby Starlet to send in to RCME so thats one of the cadboard.

 

The DH60 keeps on spinning in my head and iam also a little confused so here is a question for you Danny, do you know if the fuse of the DH60's is fully sheeted with plywood or is it steeltube with linen / nylon or what ever.

 

Ton

 

Hi Ton, glad the enthusiasm hasn't faded. I know what family stuff is like and it must come first don't worry

The earlier DH60 was wooden framed with ply turtle decking and fabric covered if I remember correctly. The first steel tube version was the DH60M

The reason I am enquiring is the Spitfire is nearly done and my building board is feeling lonely, not sure what to start/finish next

Cheers

Danny

Hi Tony, I see the mention above of the possibility of setting the upper wing at a little lower incidence than the lower wing. I am slowly working on a Fokker Dr1 to the A Lunn design from the plans service. (RC 1213) It appears that one problem with the full size design was that the upper wing was doing more than its share due to all three being set at the same incidence. I therefore wonder if the model might benefit from some adjustment to the angles of incidence...if so do you have any suggestions as to how much? It seems to me that since the upper wing has the ailerons, if that stalls first it is going to lead immediately to a loss of aileron control, plus the extra drag high up is going to pull the nose up, making matters worse.

 

I think actually the Dr1 would also have benefited from the addition of an extra bay to the fuselage, as was done for the DVII. Might have made them a little easier to land without ground looping! Still, I guess it is a bit late to redesign them now.

 

regards

John

What size have you guys decided that you are going to build these?

I have an OLD David Boddington 36" plan for the Cirrus Moth.

 

You going to get the plan published at the end?

 

Hugh

Hi Hugh, we are hopefully doing these at 1/6 scale which will result in a wingspan of around 60"

 

I am not sure what Ton's intentions are for the finished plan.

 

Cheers

Danny

John,

 

Sorry for the late reply but I have no experiance with the DR1 have it on my to do list.

Had done two flight about 2 years ago with a Sopwith triplane.

Was not my model and had lots of problems flying is it straight the model was very unstable specialy with the power on.

Had two test flights and never seen the model again which realy is a pitty would had loved to check out the model and to see what the problem was.

Sorry can't help you with the incidence on the wings.

 

Ton

Great choice of scale Danny. VERY interested in seeing the finished plan.

 

Hugh

Hugh,

 

As Danny mentioned already the size will be about 60" and yes will for sure make it a plan for RCME, but we are still a long way from that.

 

 

Danny,

 

Not much progress but have set the coordinates from the Raf15 profile in Cad and am still brainstorming on the construction and have already some ideas of how doing things.

But first have to clean up the 3View and set things up in basic lines.
