Thanks again Tony , another well done set of plans.

Great stuff Bob, when you get the DXF files, could you please email me a copy

I got the 2 x 50 mm fans into the little one today, don't know how it will go ...

Weight all up with a 3 / 2200 battery is 844 grams (just under 30 oz)

After the slight hatchet job I did on my small ME-262 and fitting of 2 x 50 mm fans, I needed to see if it would fly .. this evening there was a bit of wind BUT thought ... I had to give it a go ...

YES … YES … it flew and flew pretty well too ... straight from the hand launch, needed no trim .. AUW with 2200 / 3’s battery … 844 grams

It didn’t quite have enough oomph to take off from the grass, so I had to hand launched … not something I like to do, especially when you don’t know what its going to do

This gives me a lot more confidence to continue with the 1200 mm wing span with the 2 x 64 mm fans …

I had the plans printed yesterday, so I will now make a start on the build … anyone else building it?

WOW again ! and Congrats !

DXF files can be sent shortly.

But I still have questions about the plans.
On the large page all those rectangles stacked together will be cut
as one large outline but I'll put holes in to mark the cut lines.

There are some rectangles inside the wing outline ?
I believe they must be thickness spacers I will change the line type to DASHED on them,

BTW the monsoon had arrived at my pos ! :>(
My front and side yard are currently suitable for The Mermaid or similar types.
This happened last winter once an all was ok so I'll be monitoring as the day progresses.

Hi Bob and thanks

These are only doublers for the wing and hatch (see pic) ... was going to just say cut out of scrap 6mm Depron but decided to add them on the plan ... think I called them "Fuselage Doublers"

This is correct Bob, only cutouts on the wing are to line up the nacelles (see pic) ... all other lines are to show where the CF spar, thickness spacers (doublers for the ailerons) and ribs and formers go

Hope the weather passes you by without too much damage mate

I thought I'd seen my last STILT house in SouthEast Asia !

Just a bit soggy, no damage expected.
The same thing happened last year.
My new shop is on Higher ground so no issues there :-)

Still ... it can't quit raining soon enough for my taste !

Thanx for explanations. Got It !

I tend to work up the Outlines then forget to go read the original plans for details.

With 50mm fans being sufficient you're going to have to work on a
catapult launcher !
Rotation from the nacelles may not be possible even with more speed.

I cut out a bit the back part of my SOG Mig 29 and now it Hops off smoothly !

However The landing and taxi with Slide On Nacelles worked great.

Great flight Tony, maybe a small bungee along the ground for take off to save you hand launching.

Or maybe some fans like these 120mm 4400 watts each !!!

WOW .. now thats a fan Think it might just get off the ground with 2 of them ... do they come with a shroud? or do you have to make one?

Yes, maybe a good idea to have a small bungee, I have a bungee somewhere I can cut down (left over from the glider days)

This was just a test run Bob, to see if indeed it would fly with fans ... I am now building the 1200 mm one with 2 x 64 mm fans and I hope it will have enough oomph to get it off the grass...and, if anyone wants ... I am sure it would be capable of taking retracts

Started the build of the 1200 wing span today, cut our most of the parts and started the fuselage skeleton

Did a little work on the Nacelles and decided to insert the fans in from the front rather than cutting a hatch in the bottom of the nacelles

I used MPF for the bendy bits on nacelles so I had to do a little modification to the parts as they were a little long ... Depron should be OK and may need just a tiny bit of sanding ...

F5 needs a notch out of it for the battery floor (see pic)

Kev (Loco1) .... Do you think the nacelles will need a thrust tube behind the fan ? ... if so will a taper to 85% be OK ? .... 64mm to 85% = 54mm

Will change at my end for Cutout in F5 and add RETAINING Tabs on nacelle former cutouts.

All changes have been incorporated.
I have cutting files ready to go.

If anyone is interested in having this model cut out for them via CNC
please contact me.

There are 3 ea Full sized sheets of depron ( aka 6ea 1/2 sheets ) in this parts set.
It will take over 1 hr of Machine time to cut plus packing.

I will be asking $72 due to the extra time, size and materials.

Looking good Bob, will let you know if I find any other mistakes

You do know that the middle sheet (on your picture of the 3 sheets) is 3mm Depron .. don't you?

How much harder would it be to cut these parts from MPF Bob ? these are the bendy bits for the nacelles and would be a lot better in MPF (see 2nd pic) parts inside the Red line

Lockey

PS. When I cut out the wing yesterday, I was wondering if the CF spar should be moved (see pic) red is where the spar is now and the dotted line is where I am thinking of moving it to ...

I can do 3mm - it's in stock :-)

MPF, yup I have that too.

But it'll require a bit more layout time.

Spar can be moved at the same time.

It appears that I may, yet again, have been a bit premature.

No problem :-)

Didn't know you were going to set up for this one yet Bob, maybe hold off a little till I get further into the build and see if there are any other changes, mistakes or mods

Cheers mate
