Also, what motor/prop combination are you currently using? Considering your recent encounters with the EPP1245 props.

Thanks, Greg and everyone else for the nice comments. I received a request to put the video on vimeo since the direct download is so large:

Backyard Deer followed by FPV Quad (1 min 6 sec)


I was using the 1045/-09 combination as shown in the OMM Rev2 design on the index page. I've not been able to get the 1245/DT combination to perform quite as well in the vibration area but I think it has potential. As for the mount, I am still using a large pool noodle foam with some soft foam mounted around it. Here is a video I was going to include in an upcoming chapter which should answer your questions:

Hi ClodAholic,

A detail review and discussion about the old vs new board is linked from the first page index. Look under the "Building and Flying" section in the PWB Details area (the review is highlighted in Red).

Thanks Mike. A picture is worth a thousand words, and a video clip leaves little room for questions . I've tried replicating your foam mount, but as I have come to realize the best mount in the world is useless until you eliminate (or at least greatly reduce) the aircraft vibration. I think I was just lucky to get a really stable platform and simple "bent aluminum stick" camera mount that functioned so well. It's a shame that particular quad decided to have an argument with a brick building . I haven't been able to get a platform as stable since then . . . but I'm still working on it.

With regard to the motor/prop combination: Has anyone tested the 3 blade HD9050 props in conjunction with the DT700 motors? I know the efficiency was less than the 1045 when using the TP2410-09 motors, but what about with the new DT700 motors? Just asking because I've seen those 3 blade props and they are really beefed up compared to the props we are currently using. Of course, they are also pretty heavy .

I just flew 15 min during lunch hour with 20+ mph gusting wind. man, this is stable. you can see the gyro fighting the wind as small amplitude oscillation. (barely noticeable) just very cool. lot of fun to show off. gave a friend a chance to fly and he thing it is very cool. (he used to fly heli as well, so it came naturally to him) doing slow piro was tough as i am not as solid in holding position in wind nose in so I was drifting a fair amount.

so far, I have about 1hour on my set of 1245. just very good flying. I have tiny bit of buzz in one of my blade, so I will check it out later tonight.

Mike,

First of all, Thanks for all the hard work and information. I ordered everything to build a replica of your copter today. I plan on doing fpv mostly, but that
deer video has me pondering a cam as well.

I have been flying the wings off of my fpv easyglider for two seasons now. Although i wouldn't say i'm getting bored i do have the itch to fly something different and fly places that are not possible by plane.

nothing to do now but sit back and wait for parts to start rolling in.

To OMM or anyone who feels like chiming in...

$500 is the target price for the basics from page one...plus your own Tx I understand.
But as far as FPV and OSD capabilities, what kind of extra cash to get quality and performance like we are seeing from your rig? I don't remember but are there full specs for all the FPV/OSD stuff on page one? I am trying to come up with some dollar figures so when I go begging for money, I have an idea of what it will cost to get in the air with the best system.
Thanks!

Hi 13brv3

I tend to agree with you. I have been flying just about all types of models aircraft and helicopters for over 30 years, and in any wind above 10mph the Kquad is a handful requiring very rapid corrections, and it tends to drift downwind needing strong application of power to just hold position, and even then its rising and falling 15 - 20 feet at a time as the wind gusts.

New Draganflyer sextocopter


Now we know what Mike Dammer has been up to lately...
Look Ma! No TI!! CF Blades!(Yikes! Are those O-rings holding I see holding on those blades??) and frame! GPS! Hi-Tech Controller with 2-way data! 25 minute lipo flight time! Camera options! Will fly with one motor out! VERY N_I_C_E!!!Be sure to watch the videos.
Cost? You have to request it...I'm sure it is out of my hobby budget

industrial. my guess is 15 to 20k price tag. I do like the dual rot concept. but in reality, does not do much more than most quad.(like the folding arms though) do like the redudancy feature about motor failure flight. (but I've seen octo do the same with mk controller) anyway, always nice to see new concepts.


I've flown in gusting wind a lot with small helis, so it does not bother me. frankly, quad is easier than most heli that I've flown in wind, and no question for sure in this size class. lot less up/down due to smaller disc area.(higher disk loading) disk size of 226 sq" with 4-12" blade vs 340sq" for something like trex 450 w 335mm blade. I mean it would drift if you were up on top of it, but was not bad at all.

I don't know anyone that has tried a frame that large with 1045 props and perhaps it is outside the range of the Spectrolution controller. Even with 12 inch props I would recommend going no larger than 840 mm (420 mm to center). By the way, 1245 props with the DT700 motors are absolutely stable in Yaw, Pitch and Roll at the 420 mm to center spacing.

It is also possible that the last production run had some problems. I had heard that he ran out and had to make another run. Please keep us informed.

I am awaiting my board and there is a delay. Some boards had to be sent back due to some quality issue which needed to be reworked. Mike mentioned my order would be delayed for several more days. Hope I don't experience any quality issues or problems. I will build an OMM stock copter.

I would believe this report

I'm messing with you of course, but Seriously, wind is one of those things that's difficult to report accurately, and it's mostly because we have no real feel for it. Very few people get the chance to measure the wind where they're standing, so they know what 10mph really feels like.

I've seen some classic videos where the guy tells you the wind is 30 mph, but the tree in the background isn't moving at all. Maybe somebody should tell the tree

Rusty (Davis Vantage Pro2 in my yard, and Kestral 1000 in the FPV box)

PS, the new Dammar copter is pretty cool, though I wouldn't even bother to ask the price.

Hi Clod,
This forum can move pretty fast, so you do have to read back abit. Mike answered you in post#2941. Click on the X above the traffic counter at the bottom of the page to get to the $399 DF Experimental board: http://www.spectrolutions.com/

I was hoping he would use the index.
