Not much space if you're going on holiday with the family in a Renault Clio. This design fits into a 52cm toolbox with transmitter and all accessories.
Just thought I'll share my crash resistant design that has evolved through many drops and repairs. On impact it is now usually just a matter of replacing a rivet or a prop. The electronics and battery can quickly be removed for installation on another airframe.
The props are 15" RC timers and as shown I get about 23min flight time with a slightly damaged 5000mAh 4cell Lipo at 1500m above sea level, 25 deg C.
The difference in spacing between front and rear props doesn't have a noticable effect on stability and it flies waypoints very well.
I'll post basic plans if anyone is interested or if you want an airframe let me know.
Update: Plans for the airframe

Hi, Murray knew this drone HALO ... but do not know how to design the removable arms .... I think about it for a long time!!
Hi Lee Van, there aren't online stores where you can find Brushless at a lower price of rctimer! if I were you, I would try to trust the 5010!! .....
Alex, for after purchase support you'd probably be better off with RCTimer. I haven't read a lot of good customer support from the Goodluckbuy and other such shops. I could be wrong, but for their price for that 5010 motor you could buy known, quality motors for less.
I haven't experimented much with motors, but if you are adding a gimbal you'll probably want to use a smaller 4s battery or go to a 5s battery if you stay with the 360kV's.
For a Y6 the 360kV's would be ideal, but to keep it small you'd probably want to go for removable arms and landing gear, like the UAVforge winner shown below.
Hi,Why do you think the 360Kv brushless RCT are not good or are of poor quality?For the price maybe?See here and especially the price! What do you think?bye

What are people experiencing for throttle settings and amp draw for normal flight? I'm wanting this for FPV purposes, so GoPro, gimbal, VTx are part of my weight equation. I've been looking around at motors and am not sure what direction to go. I know the RCT 360 pancakes on 4S and 15' props are being used. I'd kinda prefer a better quality motor though. The RCT HP 4215 series comes in at ~120g each (I believe). Tiger motors would be good, but more $$$ than I care to spend per motor. HK motors are not really in my thinking...for quality issues. Sunnysky's have good performance reports and more towards the direction I'm leaning. The Sunnysky 4108 motors are ~ 112g each. The 380kv ones might be good for 15" props on 4S, or maybe even 14" on 6S (two 3S in series). 480kv look good to on 4S and 14" or 15" props. I'm hoping that feedback on performance and amp draws of already flying frames might help me make more sense of which direction to look.
I think that the motors from 360 kv to rctimer are the best compromise between price and quality performance.I also think that there would be a great way to create a frame to Y6 using the same motors.What do you think Murray?
I bought these 620kV motors a while back and was really disappointed.

They look pretty similar to the ones you are considering. They are really heavy, the shaft is small and bends easily in a crash, and the set screws come loose. I am profoundly pleased with the rctimer 4215 460kV motors.

They are small, light, efficient, very quiet, and well made. Plus the CF props bolt directly to them or you can use the included prop adapter (the bolt on type) for plastic props. They are more expensive but well worth the added expense. I have found that I have spent far more money than I intended to spend because I had to buy replacements for inferior parts. I think its better to find a way to buy good stuff and actually enjoy the hobby.
I see RCTimer is selling the 530kV motors that look the same as mine for about $18. The Sunnysky 480kV's should also be fine. You'll really need to look at you final weight and choose motor/props so that it can barely hover when the cell voltages reach 3.5V (when the ESC's cut out) for optimal endurance. The 360kV's are a bit slow for a 5Ah 3s. If you intend to fly in strong wind then you'll want some power reserve at low battery voltages or it will become too sluggish. That is when I'll unplug the electronics and do the quick transfer to the frame with 10" props.
Oops...edit to my motor choice...Sunnysky X4108S motors...not 4215 (which are from RCTimer).
Murray, I was wondering how you mounted those 15" props to a normal prop adapter. The only ones I'd seen had the smaller center hole and then two other holes for the mounting screws.
I'm in the process of trying to get some frame parts cut for me for my build. I've been looking at different motors. I'm thinking, perhaps, Sunnysky 4215s in the 480kv range for 14" props on 4S? These low kv pancake motors and large diameter props are new to me, so I'm not sure what might make a good combo.
