Relaxing in the yard and got a quick flight in.

Simplecopter 2.0 With Canopy (2 min 58 sec)

Posted by papadwight | Apr 14, 2014 @ 06:41 AM | 2,048 Views
Late night flight out front in the front yard. Been a while sense I flow out there on left side. It lets me fly in front yard which is ok with small plane. Seem to need a lot of power early. It also would not get to high, which it can go into the 100 s of feet for a long time most times. The new prop had a big chip out of it. I have learned if a prop twist or gets a good chip out. I have replaced a few motors only to put them back on. Because a new prop fixed it. Which was the last thing I did in each case. Well the battery is coming up on the cox,checked with meter. It does have a low volts in it. The cox cruiser is done its a control line plane. I learn don't put you foamy's near your solder iron they dont mix well. But this was nrver coming to be a looker. Still ok to fly and thats want I care about. Want to fly bad but wind 13 mph to 18 mph all day. Still did not stop me from going out side a looking many times. Looking at scatch building or just getting flying wing I can fly in about 12 mph winds. Got to do a lot of reading or order a crash hobby plane to put togather. Still want one of these this summer....Continue Reading

My first controlled twin-boom project.
My aims are :
- Very easy to fly - not necessarily a conventional trainer, but sturdy, stable, and forgiving enough for low skill level
- Capable of carrying some weight (heavier battery, FPV gear, drops, etc.) at low speed
- Easily repaired and adapted

Span : 800mm
Cord : 150mm root, 100mm tip, straight leading edge, forward swept
Length : 625mm (200mm fuse, 150mm wing cord, 200mm boom, 75mm tail)
Plant : Turnigy 1811 2900kV (2S 5.8A) turning 3 blade 5 x 3
Battery : Turnigy nanotech 950mAh

AUW : @400-450g
Thrust : @ 200-250g

All 6mm depron sheet.
Tail servos mounted in leading edge of wing, wire rods running through booms (6mm CF tube) to tail.
Fuselage glued directly to underside of wing.
3mm CF rod glued to inside of bottom wing plate for added rigidity. Probably not required.
Landing gear is HK Bixler upgrade gear : http://www.hobbyking.com/hobbyking/s...Tailwheel.html

MkI
The first incarnation proved a decent flyer, and although my non-existent skills let it down, I was able to get it to hover in approx. 15mph headwind. The very thin fuselage performed well in wind, but provided little room for electronics, and was destroyed in a crash, and replaced for MkIII.

Mk II
Added landing gear. Additional weight aft of CG required a second battery to maintain acceptable CG, and AUW suffered greatly. As a result, its plant was barely able to keep it aloft, but the gear is easily removed, and the plane performs well at low speed without...Continue Reading

Hello,

I made this 6 moth ago :

ppm signal from an arduino and an old joystick (0 min 43 sec)


It was based on an arduino sketch that converted potentiometers positions into PPM signal. Each potentiometer's center pin must be connected to an A0-A5 arduino's pin, one pin on +5v and the last one on ground.

I just rewrited the source code, so i'd like to share it :

Code:
#define NB_WAY 6 // number of ways
#define LOW_LENGTH 300 // How long last (in s) a low between 2 pulses
#define MIN_PPM_PULSE 1300 // minimum pulse length in s
#define PPM_PULSE_LENGTH 700 // how much more s will last the max pulse length
#define PACKET_LENGTH 21000 // How long (s) last a full trame

// trame length is fixed ! Every trame will make PACKET_LENGTH s !
// MUST NO BE MORE THAN 32ms !!! (timer's prescaler constraint)

#define PPM_OUTPUT 13 // OUTPUT PIN

int way_value[NB_WAY];
int way_pin[NB_WAY];
int way_min[NB_WAY];
int way_max[NB_WAY];

int i = 0;
int p = 0; // temp var for duty cycle calculation
int last_i_timer = 0; // last way's value sent through PPM signal
unsigned long int trame_elapsed_time = 0;
bool output_state = LOW;

void setup() {
  // ppm output :
  pinMode(PPM_OUTPUT, OUTPUT);
  digitalWrite(PPM_OUTPUT, output_state);
  
  // inits arrays
  for(i=0;i<NB_WAY;i++)
  {
    way_pin[i] = 14 + i;
    pinMode(way_pin[i], INPUT);
    way_value[i] = analogRead(way_pin[i]);
    way_min[i] = way_value[i];
    way_max[i] = way_

All great vendors. Just putting a list up so folks know where to go to get fast service. Delivery is usually less than 5 days (and I'm on the EZ Coast)

RMRC (readymaderc.com) - Midwest based
MRSS (multirotorsuperstore.com) -West Coast/Cali based
Getfpv (getfpv.com) - 3rd Coast/So.East/Florida/based
rcmanchild.com - West Coast/Cali
3drobotics.com - West Coast/Cali
Flyduino.net (Germany)
BuddyRC.com - Midwest
amainhobbies.com - West Coast/Cali
diyquadcopters.com- EZ Coast/NC (hey neighbor!)
gothelirc.com - The Great Southwest/Chandler, AZ
massiverc.com - Middle o' the Boot/Central Flo-rida/based
ValueHobby.com - Midwest
securitycamera2000.com (asia/usa/canada)


Concerning bargain basement style e-com US based/shipping sites(none of the above companies of course). . .if you see prices on hardware that are super low, you can be guaranteed someone in the food chain is not getting paid.

The victim here, is typically the original designer of the device, the guy/group who actually came up with the idea and is now watching it be mass produced and sold for next to nothing, without their consent or compensation.

Any money you spend with companies like this, is heading straight out of North America/UK/Europe and directly to the mfgr/wholesaler in Asia(prob China) (with a small piece going into the pockets of the site owner).

Items that have been engineered/designed, and are obviously being pirated(flight controllers for example), I try to purchase from vendors who are known to...Continue Reading

The Renegades

Yours truly here got so wrapped up in the SEFF magic this year that I did NOT do a show from Hodges Field. Fortunately, a band of 'Renegades' got together and put together a really cool show for the one I failed to record. At this point, I cannot tell you with any real certainty exactly who all is on this show (I'm actually listening to the recording as I type this LoL), but I thank all of you for your help with this!

Join us for next week's show, as we should all be back in our respective workshops and will be streaming our recording session LIVE again!

My hobby is RC Helicopters and they are getting a lot better than they were!!

Well, I have 9 mini Coaxels, first one I bought was a protocol Predator then assorted military helis including 2 Chinooks and 1 Large Syma S033G Coaxel 3ch Helis.

3 Coaxel 4ch Helis,(had 5 but 1 broke and gave 1 away).

6 mini 4ch FP, 1 XIEDA 9958(never could fly that one), 2 V911s and 1 V911-Pro and 1 Syma F3, also 1 is a Walkera Super FP FBL(can't fly it yet)and 1 Large FP 4ch Syma F1.

2 Mini 6ch FBL Walkera Genius Cp and Genius Cp V2 and last but differently not least is a Walkera V400D02. I actually hovered it for a little bit but ended up in disaster had to replace the main gear and possibly a servo.

I will add some pictures later.

Hi,
The first release of the MultWii Joystick feature is ready.
See the foamcopter blog for all details about the software.
Currently the software is only available for windows.

A movie of a test flight is also available. I'm flying my quad with a USB gamepad connected to my laptop (running W7 64b and a modified MultiWiiConf v2.2) which is connected to the multiwii quad via bleutooth. The flight mode is set to ANGLE and the joystick mode is set to ARCADE. The arcade mode makes it easier to fly the quad with a gamepad.

Hi guys!

This is a video of just the maiden flight without any of the unboxing or flight review stuff. Sometimes it is best to just enjoy the flight of a new plane and here it is!

Today I went out and got a few test flights on the new Align 815 and 855 Digital HV servos. The gear train is super smooth and quiet, yet extremely powerful. I did a number of maneuvers such as pitch pumps and tic tocs just to see the control response and these servos are fast. Testing them further under high speed flight loads and they were precise and were able to hold the loads applied during high walls and high speed tumbles. Look for the Align 815 cyclic and 855 for the tail, they are Digital HV servos perfect for any helicopter from 550-800.

BT, Dan, and Rocky arrived first. BT flew a motorized Radian Pro, Dan flew the Steigeisen DLG with a custom empennage, and Rocky flew an EZ Glider with a steel rod inside the wing joiner rod. We flew close to an hour continuously in great lift, but with occasional lulls. LP joined us and flew a greenish plane that I can never remember the name of. At one point a hawk flew up to investigate Dan's plane, then folded his (her?) wings and did an incredible high-speed dive at a 45-degree angle just in front of us down below the lip. A few minutes later, he/she reappeared, only to fold wings and dive again, off to the left. BC showed up and put together his ASW-?

The wind had freshened considerably and those of us in the air decided to land and pull out some heavier models. I flew left and high, walked down the road parallel to the cliff, turned downwind (misjudging the strength of the wind), then landed reasonably well about 40 yards short of my intended spot. BT also had problems with the wind. BC was helping him keep an eye on the Radian, but it quickly shrunk to a spot in the distance far downwind from the cliff. When it "landed", they saw a huge explosion of dust. Rocky and BT found the broken fuselage and intact wings about a half mile east of the slope. In the meantime, Dan had also tried to land, but had also been blown far downwind. It took a
