After a much anticipated release in 2011 the Sirius has proven to be an extremely reliable and popular FPV model for the amateur FPV'er.
This airframe has a thoroughly thought out design and a few clever inclusions such as the external ESC mount, removable electronics tray and external FPV transmitter mount on the tail boom.There are provisions for a fixed nose mounted camera but many FPV users are using the supplied plywood canopy support as a camera mount for added flexibility.
Constructed entirely from EPO with a carbon tube in the rear fuselage section and a carbon wing spar - ensuring rigidity where it counts. Being EPO, the budding FPV pilot can relax and concentrate on learning their orientation without fear, this model will take a lot of knocks and keep asking for more!!
The wing halves are a simple plug in affair, allowing easy transport and quick set up at the field.
In flight the model is stable and forgiving - another plus for the budding FPV'er!
Wing Area: 24.8dm2
Maximum Weight: 1100g

2200-4400mAh 3S or 4S Lipo Battery
Motor: 2212-2218 KV1400kv
Arrived well packed but with no instructions. Not a big issue as I have built a few planes. With the carbon fibre spars in the wings and fuselage it feels very solid. Lots of room in the fuselage for FPV gear. Two mods I found worth while (1) Larger hard rubber wheels as I fly off grass. Also the plastic nuts to hold the wheels on are unreliable I have replaced mine with colletts and grub screws. It is embarrising to bomb the runway with one of your wheels. I also epoxied the tail plane into place and instead of the screw supplied drilled out the hole and glued in a piece of carbon fibre tube.
I am running a Turnigy SK32830-1020KV motor with 30amp esc and a 3cell 2200 mah LiPo. Once trimmed the plane is very docile and flies very steadily
Overall a good value easy to fly planenice plane no dmg @ allGreat plane, well built for the price. I built mine with a TURNIGY Plush 30amp Speed Controller, NTM Prop Drive 28-36 3000KV with a Master Airscrew 7x4 3 blade pusher prop and i have 2 ZIPPY Flightmax 3000mAh 3S1P 20C running in parallel. After a few flights i have found the motor i have choosed to be a touch to powerful for this plane but i'm yet to put all my FPV equipment in it so i'm hopeing it will just rightmine arrived with the fuselage is two halves need to glue them together other than that the plane flies and handle weight of my FPV gear. flies very good with two 3s 2200mahFast shipping, no damage at all, easy built, decal are not efficient and hard to keep in place ( i will remove them all and paint it), funny look ( my wife call it : fish head ), the landing gear hold the weight, easy flyer, forgive a lot, but very stable flight for video, it bis not small plane, similar size as the bixler2, not the best EPO Foam but for this price it is a really good deal. This plane can be a good plane for FPV beginner with small budget. Good job HK
