Just a quickie to illustrate the action.

Briefly, a coned rotor blade behaves exactly like a dihedral wing, and generates more lift when slipped towards the high wingtip. So far so familiar.

BUT......

.....a rotor is also a gyroscope, and gyroscopic precession means that this extra lift does not lift the rotor disc until some 90 degrees later. So the extra lift on the leading blade causes it to rise when it is in the retreating blade position, hence a roll away from the retreating blade.

Equally, the reduced lift on a trailing blade influences that blade to fall as it becomes the advancing blade.

Whether it's coming or going, it rolls the same way.

Mnemonic summary..... "Retreating blade Rises"

Enjoyed aerobatics championship at Motegi yesterday. The weather was nice and flight was impressive! It has been suspended for these 3 years but it is back! I am posting photo my friend Imai-san took, and video I took.

Satoru

Jyuris Kairys's winning flight
He is making maneuvers I never understand??

Klaus Schrodt
Very sharp Extra 300L flight. Bear with me the first 30 sec. He is drawing heart.

Matador formation flight
Formation! What can I say? See their new 'batterfly' mirror ke low pass, too.

Greetings Alula fans. Alula construction has commenced. Well - I started a little while ago - I'm just lazy at taking photos of this one.

The colour scheme was dictated by the available texta markers - I searched for spray paints but could only get the foam eating variety. At the stationary shop I bought some jumbo markers (about $10 AUS each). I noticed that EPP doesn't colour as well as, say, depron - but I guess we are after a lightweight finish on this purposeful soarer.

The niftiest part I think is the logos. I copied the alula logo from the web site (www.dream-flight.com) and just typed 'richter' in pussycat font as that sort of looks appropriate and similarish to the font used on the web site. These were printed on ordinary paper and I used a sharp balsa knife (yes I do use balsa) to cut the characters. The template is placed over the wing and texta-d over. Pretty nifty eh!

Anyhow - here are the pictures... enjoy.

That's right, battery freaks, Max Amp arrived. 4000mAh, 11.1V. Until today, the Hyperion was considered the best of the best. Now Max Amp is the best of the best.

11/6/06 flights:
Max Amp 4000mAh
35min

Hyperion 3300mAh
27min
Magorator seemed considerably dimmer, which prevented flying far away.

For a total of 62 minutes off the ground, 20 minutes longer than the Blue Angels can fly. Can't believe how inferior the Hyperion now feels,
but that's technology evolving. A couple years ago it was nihilistic to fly just 8 minutes at a time.

Now there are kids who load down their copters with beepers, buzzers, fancy lights, and soft cutoff speed controllers to warn them of low
battery voltage. We've had success just timing the flights. When the throttle starts softening, look at the time during a stable hover. When
the throttle is still softening and the time is around maximum, fly 2 your flight box and hover just above the ground until motor shutoff.

11/4/06 flights

1 video flight + 2 night flights
Strong wind prevented long nose-in hovers on 3rd flight.
Nose-in landings & takeoffs started on 2nd flightn

Entered the nose-in takeoff & landing world 4 the first time on flight #2. So far it's mainly nose-in takeoffs & nose-in controlled crashes.
Can hold a nose-in hover without any wind for as long as we can stand it. Definitely not as fun as nose-out hover.

On flight #3 got the first night flying photos.


Incidentally, discovered Max Amp by reloading rcgroups.com over and over and clicking through banners ads. Proof again that banner ads work.

Max Amps bounced back to 10V after motor shutoff. Hyperion still bounces back to 9.5.

Back to my blog...
Man, lots of great scores lately. I got a bunch of CR stuff. Contender, Turbo and Climmax fuses. I need to get a bunch of cores cut so I can build them, so I guess its time to get Les Hovarth on the phone..

My sisters husband, Allan Dey died at age 49. He left two children, Alexander 6 and Christine, 9. He's been in and out of the hospital for years with heart problems, but it finally caught up wuth him.
I went to the funeral last Sunday, and ran into a bunch of my friends from the old days. In a way, I miss the hell out of those people, but on the other hand, I'm glad I moved out of that area. The methamphetamine use had done a number a bunch of those folks, and a couple in particular were shells of their former selves. The region I used to live in seems locked into a downward spiral of white-trash townie behavior. The best thing that ever happened to me was getting out of that area...I guess I miss what those people used to be, but I didnt miss what they had become.

On a much funnier note, I used to work with a friend, and he used to cap on one of the speed-addled charachters I just descibed. Doug loved to come up with a new bit every day about some of these poor suckers. I was talking to one of the funeral-goers who had been a close friend years ago, and hes said something that made me laugh so hard..."Mmmmm Bud, you 'member my Aunt Creepy?..."

Doug would have rotated at about 2000 rpm in his grave over Aunt Creepy.

Aunt Creepy..geezus, I couldnt laugh about it then since I had just stepped out of a funeral but h my gawd I laughed so hard about that today at work... Aunt Creepy? AUNT CREEPY? Bwahahahahah. I havent laughed like that in YEARS!

So, all in all it was a really bitter-sweet experience. I had been feeling nostalgic for the old days and for the people as I had known them- then.
I miss them for what they were, but to see them now, wow, glad I moved out. Really glad I moved out.

I started with an E-Sky Honeybee fixed pitch. It has taken a beating, I'll tell you. Luckily spare parts are inexpensive, and BPHobbies has flat rate shipping of $6 for them. So every time I break a part and need to order, I order 2 or 3 of that part, so I'm ready for next time. The problem is that I haven't really been breaking the same parts.

I'm on my second set of landing gear, my second head, and my second plate thingy. (not the swashplate, the rectangular one)

Yesterday, I was packing up the helis for my club's first indoor flying session at a new, larger gym. When I got outside, it was so warm, beautiful & calm, I just HAD to fly outside for a bit first. You know where this is going by now, right?

Long story short. I accidentally left the dual rates on 70%. I got up about 50' high, and the wind took me away, even with full cyclic fighting. That extra 30% throw would've come in handy. As it is, I had to give up fighting the wind and slowly throttle down. I wound up crash landing it on a roof. Cabin parts flying and the head popped off. The only mechanical thing that was broken was one ball link bar. But I don't have any spares of that one part. I could almost build a whole 'nother head with my spares, except for that !$%^# part.

I bought an E-Sky Lama V3 a week or two ago. This is more like it. It is designed for flying indoors, and has a much quicker learning curve. I tried flying it outside too. Same result; the slightest puff of wind and it was carried...Continue Reading

Got my Mini Graphite back from Dave Hauch ( www.git-r-built.com )
And pleased as punch. Looks great. Don't know when I'll be ready to fly it.
Weather has been cold and wet.
I want to take it to Arizona to the Electric Fest.

I asked 2 diffrent hobbyshops, and neither had heard of, or could even find a sorce for these. and those I asked I know are great sorces of information. Not that anyone reads these blogs, but maybe it will come up in a search and save someone some time.

In a previous blog I outlined the modifications I made to turn a 5 oz. inexpensive digital camcorder (sub $30 and as low as $19 with coupons) into a lightweight, 2 oz. RC video camera with 20 minute video record capability. In this blog I show the mounting of this stripped digital video camera to a foam UFO that was designed and built by my friend Steve Z. This UFO can be made to "hover" much like a helo but can also do full 3-D stunts.

Unfortunately Steve had an electronic "flame out" on the first flight and the plane crashed...big time! I recovered the camera, cleaned off the mud and grass and mounted it to a second foam UFO. I have included a video of this first successful flight however the areal video is a bit soft, (professional term for being slightly out of focus). The soft focus was a result of the previous crash and not rechecking the focus prior to flying it again. In any case you can see the potential that these inexpensive digital video cameras can bring to the entire RC community.

To see the video from the first UFO flight:

Although the footage wasn't nearly stable enough to justify it, ran a stabilization pass on it. Since most people don't have the computing power 2 play HD, we're not offering the high definition copy, but the high definition quality is better than anything achieved before on a consumer platform, simply nihilistic.

Software stabilization gives you an idea of what it would look like if the camera pitch and yaw were somehow decoupled from the copter. The uncontrolled roll doesn't take away as much as you would think. A proper gyrocam is way too heavy.

i have a castle creations 25A Brushless speed controller. I was trying to program it using the Transmitter stick as per their instruction in the manual. But it is not going to the programming mode. Other wise the Controller is working fine. any tips?

Today's location was southern Laytanton for the absolute lowest wind of the valley. 20mph. It's so consistently windy in Calif*, 1.5% of the universe's power comes from wind.


Enclosed skids completely in foam and that combined with lower rotor speed greatly reduced vibration. Since the radio antenna was attached to a skid, it was also enclosed in foam.

Enclosing of the radio antenna caused rapid loss of reception at long distances.


The higher blade pitch is undeniably much quieter. It's better than the Comanche.

In high wind and with the low rotor speed, tail rotor was completely ineffective. The tail rotor is driven by the main rotor, you see. After fighting for some time to achieve left rudder at high altitude, lost tail rotor completely and entered flat spin. Added cyclic to control the descent but that proved disastrous. Sideways crash into U. Know. What. S.A.

Next time, don't touch the cyclic and just use the throttle to try to put it down away from the property. The loss of tail rotor was due to our 3/4" tail boom padding getting pushed into the tail rotor by aggressive rudder movements. Need to secure that.

After burying the camera mount, it was time for the second crash. Seems this location in southern Laytanton has strong downdrafts from the surrounding hills. Entered a downdraft while flying downwind, descending, and that caused vortex ring state. The reflex action is of course to add forward cyclic, but with the wind from...Continue Reading
