NG 2m from Doroshenko Models

Details

The NG - New Generation 2m is a lightweight general purpose high performance model from the Doroshenko stable. The NG2m is a modern design with a slippery airfoil and an excellent finish. It has many innovative features and it is very complete. The lightweight yet strong construction is a joy to handle and the plane should give many years of satisfaction. We are supplying this great model with some beautifully made fabric wing, tailplane and fin bags. These have been expertly made from reflective fabric with black canvas edging and red and white NG2m logos and will keep the model safe from transport and storage damage.

The NG2m’s pod is a strong all carbon fibre molding with a very generous canopy hatch. This is suitably placed aft allowing generous space for a geared motor installation. Unless the firewall is recessed fitting an outrunner would be difficult. The long nose of the glider version allows ballast and RC to be fitted a long way forward of the CG, reducing the weight and wing loading. There is a little access hatch on the top near the wing root to simplify connecting the aileron servos. The rear of the fuselage consists of a long but lightweight carbon boom with pushrods (inners and outers) ready fitted. At the rear of the boom a beautifully molded carbon fin and tail mount enclose the internal elevator horn and also incorporate a clever plug-in fin mount. Overall the NG2m’s fin and tail, with its removable fin, hidden elevator connection, and superb attention to aerodynamic design is probably the best I have seen on any model glider. And as it is totally prefabricated it is almost ready to fly, with only the rudder control horn to be fitted.

The two piece wing is molded using spread carbon skin over a Rohacell type foam core. The good surface finish and modern airfoils give it an excellent glide angle and speed range. A clever innovation is that despite the very gentle dihedral break mid-span (making this a polyhedral model) the ailerons are actuated by an internal spigot from the end of the flap. This may sound iffy but it has been executed brilliantly and there is total free movement and yet no slop (free play) in the ailerons. The spigot is hidden within the ailerons and there is no external linkage visible, so it doesn't show up well in a photo. So the wing needs just two servos, simplifying the RC installation and the radio setup.

The fin and tailplane are nicely molded from lightweight spread carbon over a Rohacell type foam core, and are both light and reasonably strong. The removable fin has a strong oblong spar at its base that locates in a suitable tube in the fuselage rear. The fin is retained in flight with small lengths of clear tape over the join.
