Rainy day, but it flies anymore !

Nic,
The only parts of my Quad that are MK are the FRP chassis squares. All other parts i.e. the booms are 10x10mm alloy that I bought from the local DIY.
The booms themselves weigh a total of 100grams approx, that's one continuous piece and two separate @54cm and 26.5cm(x2) respectively.
The MK chassis squares are negligable and then you have such odds and sods such as roll cage, nut & bolts etc.

Max,
Very slick.
I take it that your motors are not equi-distant and your Quad is actually a rectangle?
I know it is only a short time period but how are the flying characteristics and, if you know, how do the three blade props compare to two blade props?

Tom.

Hi Tom,
Frame is rectangle but motor to motor si square

honestly, not perfect square 37x40cm...

he flies very well with my "old" quad board that I put from frame to frame...
I didn't touch the gain...but only flew 10mn in my garden.
Maximus
ps: I use 3 blades only for test, 2 blades have better efficiency

Fair enough.

Tom.

I have used a cut-off from a piece of pool noodle connector to make an above prop camera mount. It works very well will little perceivable vibration.

I am going to try and improve it further by mouldng some bathroom silicone into thick strip, or blocks, and sandwiching them between the rollcage and the foam/cable ties to further reduce any transmitted vibrations.

...and some video.

Quad Onboard Video 1st May 2010 (2 min 6 sec)

Tommy
Nice flight and video.
What camera are you using?
Thanks,
Neal

Neal,
It's a Panasonic Lumix DMC-ZS3.
MP4ing the video and then putting it on Vimeo really screws up the video quality though.

Tom.

I'd like to thank the group for all there help and also George for his efforts in designing a very nice product. I did some filming but need to get it out of my camera. The conditions were: 10-15mph wind and it did get a little tossed a bit for my first flight. However flew rather well for first flight. Being I'm using 4 -750KV motors, a 4cell 4000 Lipo pack, plastic plates & landing gear,my weight was rather high at 4lbs.and giving me maybe a 10min test flight or less The weight seemed to drain my battery as using alot of power to get her up. I did not have any issues with the "flipping" at all. The board seem to do its job, and I did not have to do any adjustments except for flying inputs. I'm going to either make a lighter frame & plate or buy one to get some weight off. Looking forward the new board George!!
Thanks

Glad to hear that so many people are having success with their quads.

Blindflight. You quad is the sturdiest looking thing I've seen yet! It's a compramise I guess. Strength on a heavy frame. Or longer flight times on a weaker frame. Can't wait to see some video

CJ

Blindflight,
What does she tip the scales at, if you know?

CJ,
My thinking is that a Quad on the whole does not require much beefing up unless your going for something intense i.e. twin inverted motors per boom, heavy duty gimbal and camera/video.
You could say you only have to have a beefy Quad if your prone to crashes and even then the bigger they are the harder they fall.

My Quad, which uses MK airframe squares and homemade 10x10mm alloy, is light and I crashed a good few times in the early days and it came out unscathed, except for the props.

Tom.

Fair enough tom. I'm sure I'll figure it all out when my stuff comes. I've designed three frames so far but with no carbon fiber having showed up yet I'm still just drawing. I've got a 25cm center to center mini quad, a 55cm FPV quad. And something a little more heavyweight at 120cm centers for lifting a monster camera. I'll have to post some pics when I'm next at home.

CJ

Yes, we always need photos.

Tom.

TommyGun: weight is a hefty 4 lb's 6.8oz Testing flight time was under 6 mins. Need to trim some serious weight...I have some Trex 600 tail boom's comming

Here are some pictures of parts I made and views. Still trying to work on video.

Hi,
Little problems happened this morning...I've had some difficulties to associated the 2.4ghz with the Tx, then once all ok, I've pushed the throttle, the quad took off and...no action of the sticks
Fortunately (for him) the quad plunged into the biggest thicket of brambles...recovery was more painful for me
Only on prop broken, carbon is strong !!!

I have made the arms little longer with some carbon plates and fix a little camera on the top...Here is the movie.

Blindflight,
Crikey, 'tis a pretty build though.

What is your motor distance and battery specs?

p.s. if you save your photos in 24bit instead jpeg, even though the file will be much larger, you'll retain much greater quality and the overlayed writing will not deteriate.


Max,
Did you figure out what happened? What radio are you using?

Tom.
