For a while I've been looking to build a quad just to get those smooth, slow cinematic shots. Something safe to use around people and to fly inside with.
The Squirt was the answer to those needs. Build was quite easy, plenty of space for all components, tunning was a bit harder. Nurk's blog about it helped alot.
Not the best flying quad out there but gets the job done. It's quite a temperamental machine - hates wind and ground effect prop wash.
Getting used to fly such a low camera tilt took a while but was a fun process.
UPDATE: After months of tunning and trying other stuff I found this tune from Robert Moss by suggestion of Benoit Fink AKA Fincky. It's amazing!
