The Hobbyking® ™ Y4 Scorpion Micro multi-rotor frame is a high quality glass fiber frame that offers both great looks and performance. Built from light weight yet extremely rigid glass fiber and carbon, the Y4 offers a great combination of weight savings and strength.
The Y4 Scorpion styling makes it look more like a deadly creature than a multi-rotor frame, while still offering excellent functionality and performance! The Scorpion is also supplied with 4 x 2900kv Brushless Outrunner Motors that are perfectly matched to this frame, helping take the guesswork out of the power train.
This multi-rotor frame is designed for use in the "Y-4" configuration utilizing 4 motors (2 mounted at the front, 1 on either arm and 2 mounted at the rear for yaw and lift control), we also offer a full line of multi-rotor electronics such as control board, ESC, batteries and more, so it has never been easier or more affordable to get a multi-rotor in the air!

• Lightweight but powerful motors
• Flat packed for low shipping costs
• Great for experimentation

Nice little copter. Took me about 20 minutes to assemble the frame. The instructions are a little blurred, so it was kind of difficult to tell which parts you needed, because several are similar in size. Also, make sure you glue the tale AFTER you mount the motors to it. If you glue it first, then you won't be able to get the screws in. ALSO, it doesn't come with screws for the motors. The motors need 2mm adapters for propellers. The overall construction is good. Some parts are a bit tight, and hard to get all the way together. The frame is pretty solid after you get it together. The regular kk2.1 is too big for this little frame. I would go with the kk mini, or naze32, or equivalent in size flight controller. There is not much room for electronics on the body.super produit on aurait aimer des vis plutot que de coller les poutres mais bon ya moyen de bien s amuser quand meme et puis plus tard pourquoi pas rajouter 2 moteur en plusleuk om in de tuin te vliegen
is heel stabiel om zo klein te zijnFlight review!
First off, no CG indicated in the skimpy plans! I used a ballpark from the position of the big brother (Y650 Scorpion).
It flies fairly nicely. Because of its size and weight, handles hard landings (crashes ;-) very nicely - nothing broken. Also due to its weight, it's VERY responsive. by the time you desensitize the gyros to where they're not oscillating you don't really have a "hands off" hover and always have to keep the corrections up.
If there's anything negative - and this will take more testing to try to work out what's happening - it's that the rudder seems almost ineffective. Just doesn't want to yaw. I did notice that one of the 2 motors on the back stops sooner than the other 3, it's possible it's not spinning as fast - not enough torque to yaw the little thing.
By the way, I'm using the Atmega 328 PA V3 board. Kind of large but was left over after I replaced the board on the 650 Scorpion (with the LCD one). If you use this board, don't flash the most current version of firmware, use the next one down (4.5 I think). The most current one doesn't work.
