Mr. Lifter 2011; Walter Lafouine takes over heaviest lift!! .

Who's got the best copter? It really depends on what you consider the best.

Post your copter, it's performance for one or more of the categories below and the equipment you used and any other interesting details.

Also post your ideas for other categories.

Current top designs in each category below get bragging rights as well the right to the name Mr. Lifter.

Ia Mr. Lifter - Heavy Lifter, greatest payload including battery, dead man lift style, must clear at least 6 feet for at least 10 seconds with video.

1) Walter Lafouine's heavy lifting hexa copter, 12.1 kg!!
2) Killy's big hexa 7.81 kg!!
3) pipercubdude's quad 5.45 kg payload
4) Killy's quad lifting 4.69 kg
5) Redfox74's Y-6 lifting 3 kg
6) Warthox's Y6 lifting 2.32 kg
7) Tretch5000's Y6 lifting 1.886 kg
8) Warthox's hexa lifting other multicopters, 1.675 kg
9) Wayne Young's quad lifting 1.45 kg

Ib Mr. Lifter - Controlled Heavy Lifter, greatest payload including battery with a flying task. Task is 2 minutes of flying showing controlled flight. Demonstrate controlled forward and reverse flight, 360 degree turn left and right turn (pirouettes or circuits) at any point in the flight.

1) Killy's hexa does a flip while weighted with 5.29 kg!!
2) Warthox's Y6 lifting 2.32 kg
3) Jag Svensonn's quad with 1.7 kg payload
4) Warthox's hexa lifting other copters 1.675 kg
5) Warthox's quad lifting "idodized" salt. 1.239 kg
6) Wayne Young's quad lifting 1.225 kg


II Mr. Lifter - All Out Time Duration, longest time in a single flight. Video not required (but is OK), but at least an in flight photo and detailed description required to verify duration claim.

1) timnilson's tricopter, 28 min 30 sec
2) Tretch5000's Tricopter, 23 min 35 sec
3) Captaingeek's quad 10 min
4)

III Mr. Lifter - Most Efficient Duration , highest time in seconds divide by (Ah x number of cells) of your battery. Video not required (but is OK), but at least an in flight photo and detailed description required to verify duration claim. The larger this number is the better.

1) ben123's micro hexa 712.5 sec per Ah x #cell
2) Tretch5000's micro quad 472.3 sec per Ah x #cell
3)
Tretch5000's tricopter, 1415 sec / (2.500) Ah x 3s = 188.67
4)

IV Mr. Lifter - Most Weight Efficient, payload weight divide by copter weight, payload includes batteries.

1) Killy's quad , 4.1875:1
2) Walter Lafouine's strong hexa, 3.457:1
3) Killy's big hexa, 3.3234:1

7) midnight999's hex 1.325:1
8) Wayne Young's quad 1.18:1


V Mr. Lifter - Most Durable, need video demonstrating durability

1) Tretch5000's tricopter
2) n3m1s1s's quad

Here is an example of an entry.

Tricopter weight = 380 grams
Max payload including battery = 386 grams

lift efficiency = 386/380 = 1.016

Duration 9min 11 sec, battery size 1100mAh 3s

Duration Efficiency = 551 sec / (1.1 Ah x 3s) = 167 sec per hA x s

Motors Turnigy 2730-1500
esc's Mystery 12A
GWS 8043 prop
Wii controls

I'm all for some fun contests. To keep things real I think there needs to be rules associated with the heavy lift. It is easy to bounce an unflyable payload in the air for a few seconds. I think some kind of duration or distance needs to be defined before a lift is considered real. This will demonstrate full control of the vehicle and payload. Obviously some sort of video is needed for verification.

For the lifts I think it would work to have a lift/ weight ratio. So if your copter weighs a pound/kilogram/grams, put that in a ratio with how much it lifts. I.E. the copter weighs 1 pound. It lifts 2 pounds. So the ratio would be 1:1.

Good point. How about a minimum duration of 30 seconds, payload and copter to stay above 6 feet for the duration.

Did you have a choice anyway?

Also, for this competition, anyone can make new entry's as often as they like. Made a new copter or improved on an existing entry...please feel free to post again.

I'm looking forward to seeing lots of different designs and also I'm looking forward to seeing if there are any trends that distinguish the winners.

For example, I have done some bench top testing on motors and props. One trend I have seen is that a lower kV motor when matched well with a propeller in general will require less power for the same thrust. At the same time, it seemed that the maximum thrust did not always get better with lower kV. Now I'd like to see if the bench testing has any bearing on what works in actual flight.

hmmm...

Guess 10-12kg is no problem.
But to risk all 4 of my batteries in one 30second try..... dont think so !
The such of AMP is so high that I fear the battery will suffer from this.

why not 10second and not 30 ?

10-12 kG would be very impressive.

OK, let's try 10 seconds to protect the equipment. I'll modify the first post.

Sorry I maybe got something wrong here
10-12kg is included the copter (3.4kg)

So I will try to lift 6-8kg payload

Dont know if it`s possible.
But last time I did the test I`m sure I got some more throttle to give.
The problem with FY90Q is that, after you reach full throttle, there is NO auto stabilization left !!!

Hi Gents,
To piggy back on Milo's suggestion and you are headed in the right direction, may I also suggest a few more rules. What is the point of lifting weight in a flying vehicle for 30 seconds and not doing any controlled flying? I suggest flying a set sized figure 8 course and altitudes to make it a more useful competition. The flying duration should be usable not 30 seconds, but more like 2 minutes, all documented in raw video verified for non-editing. Maybe others will have verification ideas to add too? And reqarding the duration efficiency competition...please don't make this another Mr. Holger sit motionless for 30 minutes and hover demo... A duration test being run on a continuous circuit with x minutes hover in between would be a much more operationally useful competition and information. FWIW
Cheers,
Jim

How about two categories. Dead lift as already written plus ... heavy lift with a task as you have suggested.

There you go Not to offend anyone but even those human dead lift Gents have trouble navigating themselves around It would be a good comparison
