I don't know what to say = I'm just not good enough to fly it !
All I did was crash the Invader till I broke it !

Whats the problem ?
I can't play with the supplied remote .
Left stick is Elevator , right stick is throttle and aileron .
I simply can't do it .

It goes against every fibre of my Mode 2 brain .

Anyhow , when I got to my CG test spot , the wind started to pick up .
This kind of makes CG testing a little challenging with a new model .
Also the configuration of the Tx really messed with me ..
Every single time that something happened that required REFLEXES to correct the sticky situation = I just made it worse .
I lost count of the number of times I smacked terra firma with the Invader .

Currently the Invader is resting and being glued back together .
Will I try again = HELL NO !

I will remove the flight board and put it away with the Tx for another project where no mixing is required .
Just does not work for me in this wing - Might be ok in a glider .

I have already ordered a brushed ESC , so will pop in a micro 4ch Rx and just bind to my Taranix Q x7 .

So is there a gripe !
YES = The supplied battery is garbage ..
I tried to charge it and the voltage jumped all over the place .
I tried to discharge it and the voltage dropped immediately and the charger stopped .
Cant charge the battery , cant discharge it . = Junk ..

Yes = I hate the Tx configuration .. Just makes me feel icky all over .

Here are some wing pictures.
I am going to sheet the leading edges to for high starts and the extra weight of the radios.

I got a good price on the drone. brand new in the box. I put a spectrum FPV racing rx on it, but I can't get it to work. does anyone have suggestions? This is the first drone I've had, and I'm afraid I don't have a clue about them.

I've recently completed my review of the fatshark attitude v5 including the obvious comparisons between the now competitive $240 - $300 FPV market. These have replace my Aomway Commander V1s as my regular goggles and here is why:
  • They have bright and clear OLED screen which allow me to see more detail
  • They have the removable module that allows you to upgrade to rapidfire etc. if desired.
  • They have very good antennas included as stock
  • They have the legendary Fatshark support
They do of course have their downsides including fatshark's stubborn refusal to integrate more of their "modular" design but I (personally) feel these are outweighed by their benefits.

See my full review here:

So I said the other day I would be adding the Tinyhawk Freestyle to my collection, well that's not happening right now as I just saw reviews of the Happymodel Larva X!The Larva X looks like more bang for the buck so This will be my purchase at this time.
I'll share more once she arrives.

I need some help
Im moving all my electronics from a wltoys 10428 buggy to my old Tamiya dirt thrasher
Everything went well but I need to reverse the steering servo
Its a 5 wire servo.
Any suggestions?

It was a good day at the field, winds were a little strong at 15 km. We never get 0 winds in Ontario so if I want to fly I have to deal with winds of 10 to 20 km. any more than that and I'm just asking for a crash and repairs. But managed to fly all day and take my plane home in one piece. Lots of good footage from the run cam 2. Very impressed with that camera's picture quality and price.
For most of the day I just practiced take offs and landings in the wind. I can handle a steady wind, but gusts can come at all the wrong times. Over all, it was a good day with friends, and that's worth all the bashing and crashing.
Some times I think I have too many planes. After all I can only fly one at a time. But I do like the way each handles and fly. I like them all for different flight conditions and handling. The timber is steady, the cub is almost a glider with the full wing, the mini pulse is a bullet, the opterra is a blast to feel the rush of being in the cockpit. I'd like to put FPV in all of them.
It's raining today so I'll work on the giant scale corsair from top flight. I have most of it ready to cover, I just need to get the flaps to move and work in unison because they are in three pieces. All other surfaces work nice, rudder, elevator, ailerons, retracts, It's still a long way from first flight but it keeps me busy and out of the rain and out of trouble.
Wishing you all a good day and soft landings.

The Mil Mi-24 (Russian: Миль Ми-24; NATO reporting name: Hind) called the Crocodile by the Russians is a large helicopter gunship, attack helicopter and low-capacity troop transport with room for eight passenger. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with 48 other nations (Wikipedia).

Model by Helijah for the sim FlightGear.

Twenty different colour schemes are available, some examples below. These will be available via Dropbox as the zip file is too large to post here.

Also for the first time, proper chopper sounds are available for copters in Phoenix. I just love that "wap wap" sound they make!

The files can be downloaded here.

Hi guys,
I have one question. I have the corelessCW motor, which has only 2 wires. How esc can I use?

How to check signals when using Radiolink AT9S/AT10II /AT9 /AT10

Check if the antennas of transmitter and receiver are damaged, especially the ones on receiver. The silver part at the front of the antenna is the most important as it’s the feeder line.
If the feeder line is damaged, keep flying will cause the unstable internal current which weaken the signal.

Check the RSSI value.
① Power on the transmitter and receiver with both antennas parallel and straight and within the distance of 30cm. (as picture attached below)
② Then check the RSSI value. Range between 0~-30dBM is normal and if the value gets closer to 0, the signal is stronger. If the value is between -30~-90, signal is not good and the control distance would be limited.

Check the flight environment of the antennas are all right and RSSI value is normal within the range
① Check if there is electricity substation or high voltage cable or wifi nearby.
② Check if the antenna of tansmitter and receiver is damaged or welded joint
③ Installation: try not get the receiver close to ESC/galvanometer/ metal part of the flight
④ Let the end of the receiver antenna drooped and out to avoid the signal being blocked by the flight frame.

A large part of the debugging work of the drone is the debugging of flight control parameters. The generalized flight control parameters include guidance, navigation, control law and adjustable parameters in various control strategies. The general flight control has hundreds of parameters that require human debugging, and some even hundreds of thousands. As the basis of drone control, attitude control is the first to be the first to debug the UAV flight test. Of course, the navigation parameters and the vibration analysis of our previous PX4 combat are definitely before the debugging posture. Better state.

The attitude parameter debugging method we are going to talk about today is for the most widely used cascade PID controller. In the attitude control, the controller based on the time-scale separation hypothesis is generally divided into inner and outer ring structures, and the inner ring controls the attitude angle. Rate, outer ring controls the attitude angle. The separation of time scales means that the inner loop responds much faster than the outer loop, so the inner loop response can follow the expectations given by the outer loop in a short period of time. The P (outer ring)-PID (inner ring) type structure used in PX4 is designed in this way. The design of the control law for attitude control will be discussed later and will be described separately for the Euler angle and the quaternion. Discussion. Today we will talk about how the parameters of the P-PID inner and

So yeah... I'm a bit late to the mini-quad game. Last time I was really building multirotors, the standard size was a 450mm quad...

Anyways, I snagged this little guy to get in some practice before I attempt to destroy my Gopro Hero 7 on a quad that I can't really handle And man, this thing is FUN! People told me these micro 'CineWhoops' were underpowered, so I can't imagine what a proper 3" freestyle setup is going to be like because this thing blew me away! Plenty of power for me right now and my twitchy thumbs. Only problem I have noticed thus far is in dives I do regularly get washout, causing the quad to suddenly yaw-spin when I pull out of the dive. I suppose that is just a limitation of these little beasts, so I will learn to fly around it.

Here is a (mostly) raw clip at the end of my first day flying an FPV quad. I am hooked
