I have received this baby. I have a lot of works to modify it. It takes 5 to 6 hours to build. I don't know the right CG. So, I don't dare to send her into the sky without correct CG. If someone can help me, I will give thanks to him.

only because the cheap price.. i flew this today. but the wing broke in half just after takeoff, i recommend any of you to join the 2 carbon fiber rods with another one inside. and glue the all lot.. or a carbon fiber plate at the bottom. i flew it with a 4s bat 1800 mah, and the recommended motor and edf. power is fine. cg about 10mm -15mm behind the center line of the back wheels.

could any pic a picture of the inside component layout. if i put the bat in front of the plane , i get it way to nose heavy. i was going to use a 4s 4000mh bat.im a bit worried about flying this plane, as it as such small ailerons.

* as you know that the Ducted fan is for the speed but you have to keep it all full throttle all times....it's not suitable for this type of airplane. I would recommend to have a pusher for this setup because it provides more thrust and agility in slow fly and much cheaper setup.

Box arrived today from the Aust warehouse.
The box only had the bare airframe and 2 carbon spars, contacted the hobbying support and got the usual pissoff we dont care.,
Do not purchase this item.

Just got the item. No wheels, landing gear etc, just a bare airframe with 2 spars for the wings. Aussies buyers don't go near this product, it's as bad as a naked picture of jukia gillartd.

hi, i received this model lately and start building it. there is no manual,which is very frustating as it become a skill tester to build, but once u have figured out were goes were,it is quite simple after all. there are a few flaws. like the carbon rods are too long if u dont drill the sides of the wing to get in fully in, also. the engine inlet and outlet are block, and need to be cut out,very tricky operation as u dont want to affect the airflow.i will not use the edf unit from this model as the wiring will be in the airflow outlet. there is a 3800kv 70mm edf unit,blue one at 18$ that is a great one,the wires go inside the ribs. just need to make a little hole in the foam.i will try to sit the edf as forward as possible to bring the CG forward. and help with the battery weight. also i have polish the wing and fuselage as the is a lot of little dots. that will affect the airflow. the carbon fibre rods seems to be seem from the top of the wing after gluing. the wing is so fin at the area. i am now waitting for my harware. oh, a painted model would have been nice too.

Here is the setup to get this thing flying: Turnigy 2836 out runner 3700kv spinning 68mm lander fan (because the fan is much thicker than any other fan sold here) but still using the edf housing supplied with the kit, 55A Turnigy Thrust ESC, powered by Turnigy Nanotech 4S 1800mah. With throttle management (only need 50pcnt to cruise around), the flying time is around 3,5-4 min. Few things to keep in mind: need a few days of work to assemble the plane, there is no steering rudder for take off and landing so you need to make one as it needs more than 10 m of runway to take off, rear landing wheel needs to be move backward a few cm to prevent the nose from tilting up. With all the modification above, the cg should be located in the rear wheel wells (from the original mold). Last, do not fly it in a very windy situation (above 20 mph wind) as both wings may fall apart in the air (it happened with mine)

Good kit but YOU MUST have some building experience! I decided to use a Dons 70mm setup, 80A ESC, 4S 40C 2200mAh pack. Just as other scale UAS platforms this bird will tip stall if you get slow. Beyond that its a neat airplane!

Yea finally got it into the air after six months of trying four different powersets. Found a good after market set from a competitor. This uav handles well is a kitten in the sky. Using. 4s setup place the 2.2 lipo an inch from the canopy aligning lip balances it perfectly V-tail input expo keep down the response sensitivity.touch it down soft on landing or it hops like a rabbit.
