Savoia-Marchetti SM.81 Pipistrello
Okey dokey - I'm in.
This may come as a surprise to some that I'm not doing a Guillow's kit.
(I still plan to do the B-29 one day) but I'm in the mood for a plane that doesn't have retracts, has more than one engine, is rarely modelled, flies sloooowwwwwww and is still a warbird of sorts.
I took a plan I found on the web - the only one I could find for free and tiled it in Adobe.
I'll patch it together to give me a ~ 36" span model. I'll modify it somewhat from the battleship shown on the plans for a light version that will putt around the sky on a lazy Sunday arfternoon.
I can't actually find this modelled yet on RC groups but my search was pretty lame

I'm looking at his combo right now
I accidentally printed it at full scale reproduction and then thought - hey what the hell I don't have a 48" plane with me here and with this one, I can solve one of my most probelmatical issues in these comps - getting aerial shots in flight. I can put a camera INSIDE the plane - that's legal I suppose...?
Ha ha Steve, got a giggle out of that

A pic here for scale of the project. That's one of my JR Tx's for comparison.
Actually after studying it, it's quite a lean design for a slimer.
Of course it was a FF design so is really only beefed up aroung the motor mounts.
Intersting wing removal method. I found a copy of the 1970 Aero Medeller mag on E-bay so that may help some. having said that it's only 1 page of notes
Ah well - who cares? I'll do some weight & wing loading estimates tonight.

Hi Joe - probbaly could, it may appear a busy plan but when you look at it, seems well thought out.
I'll leave that with those who know & enjoy ACad though

I'll be following with interest Phil - one of my all time favourites and a future build is an SM 79. - I also have that Aeromodeller plan and 'article' - they were frugal with the words in those days

On the frequency now, Phil! Once again, you've selected a fascinating airplane to model.
How the three-engine arrangement ends up affecting the COG and flight characteristics will be most interesting to watch. Are you considering flaps?

Thanks guys, yes I'm getting quite keen on starting but have a few things to complete first - like a P-51 I'm doing and then I'm off to Manilla on business followed by a vacation for 3 weeks where I have no access to anything aeronautical.
(might slip a copy of the plans in for daydreaming though )
Ordered my first items last night - found a set of wheel pants at Keith Sparks' awesome website www.Parkflyerplastics.com which appear perfect and will save me a lot of time.
and the method of joining them is here;
Hi Chris, not thought about flaps, If I can build light enough this ought to come in around 11oz/sq ft which will float down easily enough.
After doing the P-51 with all it's complexity, I sort of want a simple, uncomplicated and light 'floaty' type of parkflyer.
Pat, I umm'd and arr'd between an SM-79, CANT 1007 (single and twin fin) and the SM-81.
The '81 won out as it has fixed U/C and not been modelled often, plus it has a simple colour profile. I actually have the SoLite cream colour covering in stock, the red wing flashes will just go on right over the top of that in red SolarTrim, also from my stock.
So next will be to order the nuts & bolts stuff mentioned above and in the meantime a trip to the LHS to check all their quality balsa stocks and start squirrelling it away.
I love this part of the build, bringing the plan to life. Oh also I have a suite of pilots in stock - the 1/2A Williams Bros pilot busts - a few very Italian looking gents amongst them will make a fine addition to the cockpit in the correct (or close to) scale.

Here's the gear I ordered from HK last night.
Plus a swag of sevo leads, glue etc etc.
Sometimes the pix are worth more than a link.

Lots of really nice info here.
Unfortunately it's above the 3mb limit to post here directly.

Thanks Modelholic (what a good name )
I joined that site and submitted the plans, in return I got the electronic copy of the Profile magazine - bargain!
Well today I finished my last project (attached) Guillow's P-51, so now can commence construction on the SM81.
In between work & finishing that model and a vacation, all the gear turned up so tomorrow it begins....
