Well, as a matter of fact, there’s no such thing as a package.
Buying that Flitz was some kind of boutique shopping experience. When I collected my preordered and prepaid pink sample at Insider Modellbau in Zollikofen near Bern, the staff guided me to some shelfs in the back of the shop:
These are the wings to choose from. Which one of these decoration patterns do you like best? – There you go. – Now, this fuselage here will match your wing. – Over there, we’ve got some stabilizers and fins in pink. – And don’t forget your accessories‘ purse … (Sorry, slightly exaggerated, but I just couldn’t help it).
This is what I got. The kit consists of:
- 1 wing, full carbon with Rohacell core, deco pattern pink, 97 g
- 1 fuselage, full carbon, 34 g
- 1 horizontal stabilizer, hard foam with carbon reinforcements, 3 g
- 1 fin, hard foam with carbon reinforcements, 3 g
- 1 small plastic bag containing bits and pieces, 9 g
Accessories & Fittings
The plastic bag mentioned above contains:
- brass string for rudder and elevator steering linkage
- teflon tube for brass string
- rudder horns for elevator and rudder
- clamping sleeves for brass string
- steering linkage bearing
- wooden servo mount
- wing servo cable connector
- rudder horns for ailerons
- wing fastening screws, steel
- servo pocket covers
- launch peg anchor plate
- launch peg
- horizontal stabilizer fastening screws, nylon
- 1.2 mm steel rod (steering linkage ailerons)
Manual isn’t either.
The Insider guy shows me a built Flitzebogen 1, which is not far from a 2, indicating some potential pitfalls and areas in need of attention and special care. This helps a lot. For those requiring written advice, the manufaturer provides some building instructions (for the Flitzebogen 1) in the web and there is a forum on RC-Groups.
The manufacturer Andrei Iakovlev is really pushing the limits of lightweight construction. The fuselage is a very light, ingeniously moulded but more or less conventional piece of carbon fibre art work. But the wing is different. I’ve never come across such a featherweight yet rigid structural component.
However, its skin is of such delicacy, that it behaves more like a foil rather than a crisp carbon structure. Removing the underlying Rohacel core, the servo pockets for example, will cause the surface to warp. A tiny little bit only and hardly measurable, but nonetheless visible depending on the angle of incidence of the light. This is not an issue of aerodynamics but of aesthetics, if at all. But extra care must be taken anyway.
- Avoid dents caused by too hard grasps and accidential hits.
- Replace removed Rohacell core material with some other supporting structure for the skin.
And of course, a hard shell case for storage and transport is mandatory. The thin white foam sheet wraps the kit came with are irresponsibly far from sufficient.
The wooden servo mount supplied with the kit is very light as well and fits perfectly. I must confess that I don’t really know how to use its asymmetric shape and the small holes in it. But I’m going to replace it anyway. It is burnt in some areas by crude laser cut. (I know, carbon does add to the strength of the assembly, but this applies to high-tech carbon fibres only, not to dumb charcoal.)
