I started my Stampe several years ago but work and life got in the way and it stayed on my 'To Do' list.

Now with some time I am determined to get her in the air this year.

Trawling through the huge resource that this thread provides...

Off the shelf. dusted off [literally] assembled and fettling. Engine [a beautiful Saito 180] ready for a bench run before fitting.

Not too long i hope before another Stampe maiden.

Wish me luck chaps.stampe.jpeg

Welcome Martin,

The model has stood up well to being left on the shelf, the Saito should sound lovely.

My favourite colour,,,, my next one will be yellow,,

You won’t be disappointed

And the Saito will go well in it

Don’t forget to use the rudder

HI guys, what is your opinion of a Saito 1.50 in this bird? I have a restoration project (pictures posted on a few pages back) and would like to get it started.

I put a old Saito 125 in one and it went well,but then I’ve had a few with OS120,and the Laser 150

But must confess to being more happy with more power

I don’t think you will be disappointed

I think the 150 would pull it fine.

At 16 lbs. the Saito 120 flew it fine, but our field is a clearing about 800' wide and 2000' long, edged with 100' pines and sometimes on climbout the Stampe got kinda close to the tree tops.

I've now switched to the 180 and she climbs out smartly with an 18/6 prop.

I imagine the 150 would be good with a 17/6.

There's a link marked shakedown on page 158, four from the bottom that shows mine with the 180.

I have just purchased a Slec Stampe kit off of a good flying chum of mine. I will not be starting the build for a while, as I have other things on the go, but have scanned through this thread and am now reading it properly.

I would like to build mine for electric power and would also like to split the wings somehow to make transport and storage easier.

Has anyone done either of these?

Any comments / advise would be gratefully received.

Hi yes both have been done,split wings and electric motor.

I think the Ghost Squadron have built two electric ones

split wing shouldn’t pose to much of a issue

Was watching Aces High earlier,

Rounded wing tips

Well what you’d know

There heavily modified Stampe’s

Home working saves me 14 hrs a week that I have used to get my Stampe sorted

Just put her all together, finalised rigging and checked CoG.

Those with great memories will remember me posting in 2015 when I started.... Martin McIntosh was very clear about keeping weight out of the tail. He was right, I need a whopping 1.3Kg of church roof up front..

Build [without ballast] = 6.4 kg, once the weather warms I still need a coat of clear coat so will go up a bit more.

Rigged

Looks very nice Martin, will get round to building one at some point in the future, always Preferred the look of the Stampe to the Moths.................M

Just wondering Martin, do you have any diagonal braces on the outer wing struts?

Ni Nick, no I have not. The wings all seem very fixed and I already feel it will take ages to set up each time for flying!

not flown yet so could fit later if needed.

If you mean this Martin then the answer is no, I had enough trouble with the rest of the rigging. Many broken HD wires show that the wings flex quite a lot but having fitted small springs to each they now do not break and so far neither have the wings. I think that the struts probably help a lot here.

Which kit is it, the original Precedent or the later SLEC one, and what are you using to power it since 1.3kg is a hell of a lot and mine has none, built fairly standardly from the Precedent kit? It is only 6.2kg despite Solartex and epoxy coated throughout. CG is 1" in front of the upper wing TE.

My query was to Martin U as I cant see the diagonals un the pictures of his Stampe.

Martin M

it is a Precident model with a Saito 180 but 3 servos at the tail.

presently with 3 mm rod but I am planning to change them to carbon fibre.

If you mean right at the back then that is where your problem lies. Mine are as far forward as possible with a balsa push rod on elevator and pull-pull wires on the rudder.

3 servos come to about 6oz and with the placing 4 times behind c of g compared to distance in front for ballast means at least a pound of lead to balance the servo weight alone, not withstanding any additional tail weight that may need compensating from the build process.

saito 180 is a few hundred grams lighter than a Laser 180 that I have in mine (which balanced slight nose heavy with no ballast) so that also would contribute to the weight needed up front.
