Here is the latest revision of my favorite hobby project based on Multiwii project.
In two words: it's pretty stable, improved and extended version of Multiwii.
- INS (inertial navigation system) integrated with GPS and Baro
- predefined PIDs to fly out of the box for frames 330 and bigger
- completely different precise althold integrated with INS
- right altitude management by setting desired vario (vertical speed) with throttle stick
- single PID controller for hovering and altitude management
- stable hovering trottle estimator/corrector by I-part of alt PID controller
- smart land detector
- reduced effect of air-cushion to avoid incorrect raw baro values and jumps near the ground accordingly (integrated with INS)
- controllable by desired vario (vertical speed) landing
- new SAFE_ALT_DURING_AH define. It helps to protect descending less than specified in define altitude. Activated when SAFE_ALT box activated in GUI.
- precise, rapid, sensitive to external perturbations (wind, pushes) GPS-INS position hold (INS_PH_NAV_ON define)
- possibility to fly with activated position hold and stop at predicted point on stick release (tunable by Pos-I value at GUI)
- wait for target altitude at RTH and WP navigation
- skip whole RTH cycle if distance less than RTH_RADIUS meters and make a landing
- safe and soft takeoff on RTH and WP Navigation
- for safety prevent arm if RTH or NAV switched on

Had a couple days in a row of cold and rainy weather,fortunately I have a small fleet of micro quadcopters to have some indoor flying fun My "whooped" Eachine E010,Eachine H8 mini and JJRC JH1000 keep the flying going during inclement weather:got a few others as well but these ones have been getting a lot of flying time recently

Here's some photos of the Hobby King Le Petit ARF. The model is impressive and a great candidate for 1/2A conversion. The only issue I've experienced was a pushrod not glued. The aluminum rod goes into a carbon fiber square and has shrink tube over the point where they meet. One pushrod had no CA and was moving as I was connecting the elevator clevis to the horn. I recommend pulling the pushrods out and checking them.

I was at Target the other day. I happened by the toy department and spotted this TINY (1") drone and controller for around 30$. I doubt that it could lift any kind of camera, although maybe a SPY CAMERA like you see on TV. Very stealthy.

I fly a lot at night using lights only because when it's dark you can't really see the body of the quad, you have to rely on the lights. For this reason I did a modification to the front lights by turning them facing forward instead of upwards. I found that in the stock position even though you could see all the lights, at certain distances you still couldn't tell the orientation. By pointing the front lights forward instead of upwards you can definitely tell when the quad is facing you because you see the bright headlights pointing your way.
You have to cut away a little bit of the plastic to make them fit facing forward and then secure them with some hot glue. A side effect of using the hot glue is that it actually increases the area that's illuminated so the lights look bigger. And in case you're wondering, they're actually quite durable even with head-on crashes.

Hello every one, im trying to start a business in mapping and site photography through a crowd funding web site https://www.youcaring.com/lancegraham-699283
Please Share if you can
im looking for opinions on the best reasonably priced equipment
phantom or inspire
dji or 3dr
and probaly most important the camera type and sensors
any advice and or opinions are greatly welcomed
This is 90mm Micro FPV Racing Quadcopter Based On F3 EVO Brushed Flight Controller,
My sample came with built in Flysky receiver, i will test to bind with Flysky FS-i6 and FS-i6s Transmitter,
For FPV will test with Eachine Racer FPV Drone 7 Inch 5.8G 32CH Monitor,
So I bought some wood last night for the next airboat hull. Over the next few months ill be saving up some money so that I can get the powertrain I want.
This is going to be a 12 cell system. I need to get the Motor, ESC, Batteries(two 6-cells in series I think), a new high torque servo (steering).
I was thinking about adding a flap under the boat that drops down like airbreaks under the water and pretty small. If the boat is going to be going in the 60mph+ range i want a way to get it to stop fast!
Later today I'll start on getting some plans worked up on graph paper! I know the prop will be around 16 inches long so the tower will be around 9 1/2 inches tall. As for how long and wide. I have yet to decide.
Im also going to try some new building techniques to get this really cool looking!

I'd like to mod a V911 to a brushless setup.
Ordered and received a micro 7000KV motor and a MX 3A ESC from HobbyKing. It states the ESC will process PPM as well as PWM signal.
Could anyone please help me in the direction to wire this up? I mean the "+", "-" and "S"... As the heli receiver has a PWM output does that mean I do not use the "+" and "-" ? Only the battery connectors and the "s" from the helis main board? Please help?
Now I am in a confution that, does it produce enough thrust . May be I could get a total of 5Kg thrust right??. I think after building the airplane body it may be weighs about 8-10kg.
Wing span is 2.4 meter.
I am sorry for my English if I am wrong...
Will it work??
First time I am trying on scaled model plane and my knowledge on this is much lower than experienced ones like you..
