Intro
My first build! Had a great time putting it together and learnt a lot in the process. Hopefully didn't counteract said knowledge acquisition by inhaling too much lead solder vapour. I highly recommend these DYS 1407 4300kv motors. They rip!

Build notes

• The Realacc Y150 stack housing is fairly cramped. I had to use some spacers at the front to widen out the housing so that the FC had room and wasn't contacting with the frame or the RX or VTX strapped to the roof above it.
• The Matek PDB came with the Realacc Y150 frame so the PDB cost should not really be included.
• The King Kong 90gt prop guards were lying around and proved to be handy to use as protectors for the FPV cam.
• Only one ESR capacitor (for smoothing power for cam/VTX transmission) was used. 10x are in the list here.
• 5 zip ties used. 2 for antennae, 3 to hold the camera protector structure (King Kong prop guards + plastic ring from the mouth of a moisturiser bottle to keep the guards out of the view of the camera as much as possible)
• Rubber bands used to hold the VTX and receiver away from the FC on the roof of the frame and to steady the camera from vibrations.. Seems to help with "jello"

Flying impressions
This little quad has shiteloads of power. Much more than my first RTF 210 brushless quad. I'm still getting used to how much momentum is generated when I punch the throttle. It just seems to float more than I expect and I sometimes find myself thinking "drop! drop!' when approaching obstacles to fly under.
The motors were running fairly hot/warm originally but this seems to have gone away after raising Pitch and Roll P (Proportional) gain.
Flight time on the 850mAh 4s batteries is about 5 mins or so of fairly heavy thrashing.
Don't know how much it weighs but I can think of a few ways I could cut down the weight for a future build that I'm sure would help with flight time.

Warning
Those little DYS 30303s coupled with the 4300kv motors mean VERY fast and sharp little blades. Watch your fingers folks!
