This is pretty cool.

That was a proto type, I haven't seem any videos with the kit version yet at 10 percent .Would be interesting, I thought for mine 44 percent was minimum (2400) any less and it was barely flying , 2700-2900 is about right.Anyone replicate the 10 percent light 3d with there stock kit?Curious

I just got my first CP heli kit, a TREX 250 DFC. I went small because I am not a good pilot yet and don't like the the large blades going at high speed. I am thinking when I get better, to try the compass warp and start out at low head speed. I also love how quiet it was in that video and really like the way they designed the air frame, dual belts, rigid head, etc. That video really made it look like something I could move into one of these days.

when that video was shot i was running a 1500kv motor and a 17t pinion, with the stock setup to get that head speed you need about 40%.

Thanks Dave ,that clears up that mystery,I couldn't figure out how you did it otherwise!

[Dave Ketelhut]

yea, and at those head speeds im pretty sure just adding the canopy it wouldnt get off the ground, it was a handful to fly LOL

[Stevemech]

That is still my favorite Warp video and awesome flying, the main reason I bought the Warp!

Great vid!! Any info other than a flat 10% Throttle curve? Whats the swash travel set to? Pitch curve settings? Pitch at hover? Thanks

[Dave Ketelhut]

i was using the koby esc Gov at 10%, pitch was 13° and cyclic was 7° for step J swashplate cyclic geometry step in Beastx.

Not exactly advisable. You could get by with a relatively low headspeed like 2600 range but much lower and you really need to be a skilled pilot. When the headspeed is that low you have no room for error as you don't have the power to get out of things if it goes wrong and you need to have great collective management skills to prevent you from bogging the heli down to the point where it can't fly. Low headspeedflights are neat, I have a somewhat low HS governor setting on my stretched 450 but I am past the stage of learning the basics and thanks to the mCP have relatively good CM skills. Just my .02

I enjoy the low HS...IU1 set at 2500 gov by Sk720...flys great..w/canopy on..no problems at all... a must try for everyone Using Thor 1350 35c lipo at aprox. 210g. Nice light packs.

Good points. I was just thinking of running a low headspeed to do simple, upright flight. I am not as far along as you so I am not talking about doing anything but very simple stuff. I do find it cool though that he could do all that in the video with the low headspeed. Maybe someday I could get that good.

I have 30 flat 65 flat and 85 flat curves on a koby55. 30 and there's just enough pop to flip inverted and push up and away. Good fun if your bored

Do you know what your hs is at those different settings?I'm thinking 2400 hs is about minimum?

No idea at the moment, down and waiting on parts. Using the stock pinion and motor.

I tried 10% as at that time was unaware that Dave k's setup had a higher kv motor and it wouldn't get off the ground, tried 20% which worked but useless then 30% which is just about flyable in FFF, anything else is silly. Happiest at 65% for now
