Skymaster (oz15588)
About this Plan
Aeropiccola Skymaster. Radio control sport model. Wingspan 1460 mm.
Update 10/10/2024: Added articles from 1964, 1971 and 2012, thanks to Pit.
Quote (google translated): "SKYMASTER RADIO CONTROL MODEL
This model, known throughout the world as one of the best models in the single-channel series, has all the necessary requirements to be preferred by beginners in the radio-guided category. It does not present excessive difficulties in setting up and above all it can be assembled easily and quickly, as is expected by new modelers. The main characteristics are: Wingspan mm 1460; Length 970 mm; Wing surface 29 dmq; Weight gr 850.
The SKYMASTER adapts to all small-displacement motors, in any case not exceeding 1.5 cc, and to all single-channel radio systems.
Anyone who wishes, because it is naturally up to the task, can transform this model into a multi-channel model by adapting the horizontal tail plane with a mobile part and equipping the model with a three, four or even more channel system.
The prototypes made by the author and his collaborators are of various kinds. The first was the classic model, faithful to the description and drawings reported in the article.
The second was instead equipped with three channels and equipped with a 2.5 cc engine and with floats for landing and take-off from the lake (see photo).
The third and last version was the one with the four channels. The wing was moved to the lower part, the wing dihedral decreased by 5% and naturally four independent controls were introduced, namely, elevator, rudder, ailerons, engine.
SKYMASTER in multi-channel version, is easy and safe. In fact, we intend to publish the description and drawings of the modifications shortly, thus giving the opportunity to the not many, unfortunately, owners of multi-control equipment to be able to create an excellent model with a not excessive expense. As for the normal model, as we present it, it is truly excellent as a whole. It has a slow and safe flight; a normal and not too fast climb; it can be easily controlled without bad surprises and with a little 'hand', it is also possible to obtain good aerobatic results.
In this regard, we remind, especially to radio control beginners, that with single channel it is possible to obtain aerobatic figures: all you need is to have the model perfectly centered and carefully set up and, by exploiting the gyroscopic torque of the propeller, you can obtain, in addition to the right and left turn, also the descent and the climb.
It is well known that by insisting on the turn on the left side, that is on the side of the gyroscopic force of the propeller, the model tends to plunge while on the other side, due to the opposite effect, it tends to climb. Taking the right 'hand' it is therefore not impossible to obtain even the looping, even if as a figure it is not perfect because it occurs, as they say, on the wing.
In any case, for further details, just contact our colli borator who will be happy to give the necessary advice to anyone who needs it.
CONSTRUCTION: FUSELAGE : It is no coincidence that I start from this organ, in the description of the model. In fact, the fuselage, although not such a delicate organ, like the wing or the tail planes, is the main rib of the entire complex and in the specific case it is also the organ that contains the main control device.
A series of 6 rectangular section frames form the main shape and strength framework of the fuselage. Frames No. 2-3-4-5-6 are made of 1.5 mm aviation birch plywood while No. 1, which supports the engine mount, is made of 3 mm thick plywood.
Four square section hard balsa strips (5 x 5 mm) form the stringers of shape..."
Update 10/10/2024: Added alternate plan, thanks to Pit. This (low res scan) is the later Skymaster 2 version (dated 1965) which shows RC installation with 2 channels, as opposed to the single-channel original plan.

Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

I think every rc Italian modeller made a Skymaster once in their life. I remember a relic of this model in my home too when I was a child.Pit - 10/10/2024
The man in the article photos [main pic] was Franco Conte, owner and founder of Aeropiccola company of Turin.

Now we have 2 versions of the plan here, the original and the Mk2. If we can get hold of a high res scan of the Mk2 plan (both sheets) then I think we could split this into 2 listings.

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
