it was on 2s 450mah and 1306 4000kv with gemfan 5125, pretty lightweight. the weak point is in the middle of the arm:

HI Hugnosed,

Thanks for the photos and experience.    I really appreciate it.   

I thought I might put my spare set of Brotherhobby 1504.5 motors on that frame with a JHEMCU GHF405 flight controller.

I will likely plate the motor mount locations with a custom fabricated carbon fiber sheet or a section of of a production arm;  I always have spare arms in the parts bin;  Yeah, sometimes I just buy spare arms if I like the looks of them and the price is right.   

You know, I am no stranger to arm extensions, overlays, and custom fabricated carbon fiber parts.

In fact, I have been rather impressed with my two quads, Phantom-X and Phantom-4X, built on the GEPRC phantom frame with arm extensions. 

I will see what option works the best for me.

Thanks Again. 

the frame is one of the lightest choice. i beleive for flighttimes it might work nicely, the stiffnes-lag comes under load not while cruising. not sure if you have a near lightweight frame on your list, but i guess it could work for flighttimes without crashes.
im still using this frame on my original hyperbola for performance, i didnt crash it allready, as i like to bash with it im allways in danger while flying xD

im not sure, but i beleive its pretty expensive as a single product?
the benefit of the frame is truly weight, nothing else

Hi Hugnosed,

Well I am not a basher; no acro, racing, or that stuff.  I mostly fly with the throttle at about 20-30 percent; I am an easy cruiser; just want to hang in the air until the battery runs out.

My first objective is keeping things below 250 grams since I am trying to stay out of the way and under the radar.

I am also trying to work on my 5K badge, so having enough Fly Time to make it to 5K and back has been a consideration. I would like to be able to may the 5K with an AUW less than 250 grams. Not sure that is possible, but worth a try.

Yeah, I have started a 7 inch build, BEAST, that will definitely NOT be sub-250, but might make the 5k run. Might be useless after the new FAA regulations take effect; and are enforced. 

Thanks for all of your help.    

hmm, my 18minutes flight was very slow, cant imagine what distance that could be. i flew near the ground, i guess windy conditions could give a problem.

awaiting your 5inch ul-longrange try, i would realy like to see 5k on an ul 5inch :-)

i beleive there could also be options to go even larger than 7inch and stay lightweight, a 9" with lightweight carbon props and a frame out of carbon tubes.... with your orange 2306 motors :-)

Hi Hugnosed,

After I finish the two 7 inch builds, I will put together an ultra light 5 inch with the Hyperbola frame. 

So far, my longest Fly Time was over 21 minutes with the Katana-LR4 running a 3s 18650 pack. It will be interesting to see how the 5 inch Hyperbola build does using the same 1504.5 motors.   

very intressting
also if used with 18650cells


my 18min flight was with a tattu 1000mah 75c, there is still a lot of achiveable flighttime from battery choices :-)
