Do you feel the need for speed? The Hobbyking Viperjet is a true, fully aerobatic speed machine with stunning good looks to match it's performance.
The Viperjets composite fuselage and pre-covered built up wings help propel it's slippery shape to blistering speeds, the flaps help to slow it down enough to land at almost any flying field, the inclusion of a rudder means a wider envelope of aerobatic performance over the usual bank'n'yank capability of so many jets in this class, giving the pilot so much more to explore beyond simply outright speed. The "winglets" will provide lift, right down to the slowest of speeds, meaning a greatly reduced stall speed and excellent flying manners.
A full hard-ware kit is included, smooth inlet ducting is pre-installed, just leaving you to fit the supplied efflux tube. Fixed landing gear is also included or you can belly land. The large canopy area gives you plenty of options for Lipoly batteries, ranging from 4s~6s for the real speed freaks!

Received another one of these last week , no issues in shipping :)
Retracts will go in (changesun 15v2) drop right in 15.5mm thick , xhangesun 10b v3 edf on 2600kv 6s and castle 100 amp esc . Hitec servos all around , should come out around 5lbs with 6 lbs of thrust.
CG at 76mm , video to follow.
Receiving for Christmas present. Opened up and gave the model a good once over. Very nice fit and finish, well packed and thus damage free. No instructions with model but I saw this on RC groups. Looks pretty straightforward. For a very low cost composite jet I would say very good.Ok Flight Test : The Final Flying Weight was 2.1 Kg using a 1.7 Kg Thrust EDF on 7 Cell ( 70 mm 5 blade HET fan with 3W-25 HET motor ) consuming 50 Amp at full throttle ; Battery was Nanotech G2 A-Spec (two: one 3S and one 4S 2200 mAh) in series.
On takeoff , a small rock on the pavement broke off the left landing gear on the wing but took off with authority ; Controlling the ailerons was difficult with landing gear hanging down on one side ; Landing was smooth but very fast ; I did not deploy the Flaps on first flight to avoid any unpredictable behavior . No major damage but will try flying again soon . The batteries had 70pcnt capacity left upon landing after one loop of light . Hope to have better luck next flight .First Impression: boxing good; came with cracks in the leading edge of the left duct inlet -fixed with gap filling glue. Also cracks between both air inlets and body. No box damage -this is factory cracks. The description says dry weight 950gr . True but left out the hardware package weighing 220gr : so no electronics dry weight is about 1.2 Kg. Using regular 9g servo for Ail,MG for flaps ,steering and rudder with lightest edf unit (non metal ) with 60Amp ESC lightest electric landing gear from hobby king and 4gr wheels. Total electronics without wire connectors and receiver was 440gr . Add 40 gr connectors and 15 gr receiver :total expected flying weight with a 4s(300gr ) or 6S(400gr) 2200 MaH is
:2.0 -2.1 Kg at best . Pretty heavy ,so get a strong EDF system.
