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.
We stock both electric and glider versions of the
NG2m. The electric model can be built light and flown as a 2m F5J type thermal soarer or a higher power motor can be fitted and it can be flown as a warm liner. Similarly its excellent speed range allows the glider version to be used on the flat or as a light/medium wind slope soarer.
All the NG2m models in stock have the nose in place (as shown in the studio photos), and can be built as gliders or electric models. The
Light electric layup models include a 32mm firewall in the accessory pack. The reason for not installing the firewall is so that the customer can decide if he want to fit the firewall at the very front and use a probably geared inrunner, or to recess the firewall and fit an outrunner. The
Strong glider layup models have a towhook fitted and a stronger layup wing to cope with winch launches or big slope aerobatics. The wing on these models is about 40 g heavier and the other parts are a little stronger also.
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.
The complete accessory pack includes all linkages. Apart from RC only two 20 cm extension leads (for the aileron servos) will be required to complete the model. Supplied with wing and tail bags.
