This is a Morane Saulnier Type H monoplane I built in Depron. For reference, I used Emanuel Fillon's rubber powered version plans, enlarged to 160% and built from Depron instead of stick and tissue. I made some changes also -- I reduced the wing incidence of the original, which looked like quite a lot  to me. I also built a conventional rudder and fin, instead of an all moving stab.

The wingspan of this model is 20" and wing area is 90 sq. in. I used a helicopter V911 brick from Banggood. Motor is an 8.5mm WLToys geared coreless.

Present flying weight is 53 grams.

It's a fine flier in light conditions outdoors -- actually it can fight a small breeze quit well in the right hands and is very resistant to stalling. It flies very nicely indoors, too.

That's a really nice looking model. What size(s) of Depron did you use ? I'm assuming this is rudder, elevator and throttle. Not being a constructor of foam models ( apart from combat models in the late 70's !!! ) or an RC flyer I am still interested in prototyping models in this material for freeflight applications

Hi Mefot, I used 2mm Depron in this plane. I can no longer get that here in the U.S. though I have a number of small cutoff sheets left in stock.

All is not lost here, though....I did a lot of density and stiffness tests on foam and other materials at one time. And I found that a 3mm foam that HobbyKing sells has the same weight per area as 2mm Depron does. And more stiffness.

Speaking of free flight I did try a rubber powered 2mm Depron and tissue adaptation of the Boston Beancraft Banana bostonian once. It's in my avatar. It was heavier than I'd hoped and I had trimming problems indoors (it was winter) resulting in enough damage to the fuselage that I set it aside. But I think a second version could be made to work and possibly come at the 14 gram limit. As usual, the tail turned out to be the place to concentrate weight reduction. I think I shouldn't have moved the rubber peg aft and that may be the reason I had to balance with weight in the front. Probably too much greed on my part!

I might try that model again some day in the light of present experience.

Thank you FreeflightModeler! The little Morane is my favorite of all the planes I've built.

There's an outdoor video of it flying in winter when I was first testing it. It was deceptively gusty, with calms between. Practically unstallable. But the downwind landing, uphill did lack grace:

and here I was trying it indoors for the first time. (Pardon also the initial ground loops. Can't blame that on wind.)

That's a good inflight pic.It shows the landing gear details nicely too.

Thanks for the reply  Smiley Not sure if you can get it over the pond but I have just started experimenting with Grauper Vector Board. It seems to be almost indestructible but I've not got to the model building stage yet  !!!   Grin
