Scratch built Gws Edf 50 Me 262 Schwalbe thread


Hi guys !
Here's a new buildthread about the Messerschmitt 262... I know it's not the first, but this one is a so nice flyer... I couldn't resist.
I designed her to be easily flyable and to allow (almost) everyone to fly it without "steelnerves". The first one i built 4 years ago used the brushed motors version of the GWS EDF 50, so she was underpowered and motors lifetime was very short (like the real one...). When brusless motors like Feigao 1230 were available, i decided to build a new one, and i was not desappointed : She was just like i wanted, with a nice scale looking, enough power, reliability, lightweight and good flying characteristics. She's not supersonic, and only needs cheap equipments.
Let's see some specs :
WS : 1100 mm (43,3")
WA : 18,5 dm2
W : 555 grams (18,69 oz)
WL : 30g/dm2
controls : Throttle, ail., elev. (rudder is possible and recommanded)
2x GWS EDF 50 (2x3x3 rotors), 2x Feigao 1230 5300kv, 2x Castle creations Thunderbird 09, 3s1p TP 1320 mA.

As usual, the airframe is out of 3 mm Depron, with use of foam blocks, 6mm deprons, 0,4 mm plywood and 3 mm balsa in some places. The main preoccupation during this build is to save weight everywhere it's possible to get the best Thrust/Weight ratio and wingload. There's no power to spare, so it's a good thing to keep an eye on the scale...
Of course, it'd be possible to overpower it with a pair of microfans and razor 300, for ex. But it'd be essential to reinforce the structure with a sandwich balsa/carbon:balsa spar and hard balsa leading edges, and to change thrustline by adding 1 downthrust.

Fuselage


The first step of the build is cutting all the pieces from 3 mm Depron : Formers and basis.

The upper fuselage is built first. Formers are glued on the basis before glueing the rear fuselage skin panels between formers F5, F6, F7, F8.

Nose cone curves are made with small 3mm depron stripes glued between formers F1 to F5... this method will remember something to those who are used to balsa works... Don't worry, it's not so long it seems to be !

Vertical fin is built before to be glued on the rear part of the basis (beware of angles, and don't forget the elev. pushrod !). In this step of the build, you'll have to decide if you want the rudder control suface... I've just one thing to say : I miss it on mine !
Before starting on the construction of the lower fuselage, don't forget to draw the stab. location and incidence (0), it's the best moment.

Of course, the lower part of the fuselage is built using the same ways as for the top. The main difference is the battery tunnel in the nose cone. With holes everywhere for battery cooling.

Lower part of nose cone is also built by glueing 3mm depron stripes on formers F1 to F5

A small foam block is glued and sanded in end of the nose cone construction.

Work on the rear part of the lower fuselage (there's a vertical sheet of 3 mm Depron between F7 and F8 formers)...

Because of the small radius, work on the tail cone is a bit different : Two sides are glued first. Then, the bottom (2 x 6mm Depron is glued and sanded.
