I thought about that but wanted to keep it simple. I am still not 100 percent sold on the quads. Most of my flying is with planes and I hardly use the rudder or yaw control. Still doesn't feel natural. I will keep practicing because I like the idea of a quad. Once I am better at flying it I will probably attempt to build a folding frame. Good luck!

Snipe,

You have to wake up that Left Thumb if you're going to have fun with these multicopters. There is no way to really enjoy them if you don't.

I suggest you get on a simulator and fly the crap out of some Heli's until you're sick and tired of doing it. It will teach you to fly with yaw control, which is a whole 'nother world of flight.

Its kind of scratch built because i sourced all the parts from different places.

i replace the fiber glass booms with aluminum round tube because well i broke the last ones

very sturdy now and everything dialed in, with out the cradle it is very twitchy and over powered, when the camera cradle is attached it flys a bit sluggish, (more time to think )

running a kk board but still debating what more advanced board to use

got some more time on my new scratch tri today, this is the 5th time i've taken it out,starting to get the feel for it,

pretty sure i like it more then my quad, i can't believe home smooth they are, so light and floaty,

sorry for the weird video situation, it was the only way i could wedge my phone in the park bench lol.(helps to watch in full screen).

didn't break anything at the end, just straight back up and off again, very much enjoying the robustness of a home build over fancy motor mounts and carbon fibre.

Hi all,
This was my first successful Xcopter build using the HK V1 controller. Everything on this build was around $100. I was able to get the gyros set to perfection on this bird and it flew like a dream with 8" props. Then a friend wanted to buy it and offered what it took for me to part ways with it.

Stable Scratch Built Quadcopter Xcopter (3 min 3 sec)


I shot lots of video with this quad and now that it was gone, I had to build another. I had been assisting other people on their builds but then it was time to build another for me. Ha ha! This is what I ended up with. A larger frame, better motors, 10" props, and used the HK i86 board. This controller was super easy to set up.

Building on the success of this combination, I replaced the i86 board with the KK2 board with auto level and returned to the 8" props which seemed to work much better.

However, battery life was shorter with this setup so when an offer came, I sold this one too. What I built next was a foldable T-tricopter. It took me a while to come up with this design and now I plan to use it on an H frame quad copter for an even more compact package. Please excuse the silliness on this video. I watched Batman, The Dark Knight.. Ha ha!

I am now working on a Power Tower. I've flown it in my garage just to dial it in and it's a monster to tune. Next time I fly it (whether it's indoors or not) I will get some video. Seems every session I've had so far ends in broken props and at times a stripped servo. But when I replace it this time, I'll shoot it.

Take care all,
Ron

I moved the kk board under the lexan for protection after I dropped the bird from 20 feet on its top. Next stop is landing gear with integrated camera and lipo tray. Thanks to Mr. Suburu for filling me in on default settings resets to plus quad. I spent a couple hours dialing my x quads P and I values in with plus quad settings. I was frustrated to say the least. Flies quite nice now.

last two pics are before the board was moved.

If you have some of that plexi left over, that would make for some great battery protection.

Small Quad Refreshed with APC E 7x5

Those props worked, but balancing was a pain as my prop balancer does not allow those to turn more than about 45 degrees. Then a blade hits the bottom. Clearly normal 2 blade props are easier to balance under those circumstances. I still balanced the 7x3.5x3 props well and it was all smooth and with few vibrations.

But I always thought that I should try some other props too. If only just for fun or educational purposes.
So I got myself the only 7" props I could find in push and pull configuration: APC Electric 7x5 props.

Pretty well balanced (1 of 4 was perfect, the other ones needed small amount of cellotape) out of the box. Since the prop adapter I have is a 5mm one, and APC does not seem to be a friend of mm, I had to get some Hyperion adapter rings. Very easy to put into the puller props, but impossible to fit into the pushers, so some light sanding was required.

But it was worth it. When going from the Gemfan 7x3.5x3 to APC Thin Electric 7x5 props, this happened:
  • Hover throttle moved from about 70% to 43%
  • The sound is way less high pitched (neither good nor bad, just an observation)
  • I had to use less P (going from 7.1 to 5.1) as otherwise I get fast oscillations
  • It's not docile anymore and acts much faster and more sensitive for roll and pitch changes (yaw is pretty much unchanged)
  • When giving too much throttle (about >80%), the motor mount vibrate. For now I simply limit throttle to <80% which is plenty much power left.
  • Although eCalc told me the props will stall, power usage did hardly change: Before as well as afterwards I use about 1600 mAh for 10min slow cruising.

Much less a beginner quad than before. I'm glad I did not start with those props.
The biggest surprise was the lack of power usage.

As a result, for my larger quad (35cm diagonal M2M) I'll definitely try different 8" props: Graupner, APC E and SF, GemFan CF and whatever else I can find.

It seems that every year on October 31st, there are a lot of short bandits that come around to rob us of candy. Well, this past 31 Oct, I had something in store for them. I decked out my T-tri in a ghost outfit.. Moo Hoo Ha Ha Ha Ha Haaaa!

Happy Halloween (1 min 39 sec)

I've also found that if you tune the HK i86 board, it will hold it's position quite well. I had my Tri staying in an space of about 10 to 15 ft slowly drifting back and forth, so I thought I would get some video of this.

aerotestra (Air Shell) Multi Rotor Airframes

This is a design that I have been working on for the better part of a year. It occurred to me a frame constructed this way would be lighter, stiffer, and more durable than the frames currently being made. It is 555 mm frame based on my first scratch built version. It weighs in at 395 grams. It can take a petty tough landing without any damage.Name: IMG_1047.jpg
