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

So what interested me in the Invader flying wing .. ?

First there was price , $66 Bananas . $44.40 Green Backs
Second , the Rx ...
It looks to be a 3ch job and takes regular servo plugs .. ( Yes the Invader has servos in the wing )
Also it has a inbuilt ESC for brushed motors .. So the Rx itself looks to be interesting ( has a afterlife )
Just wondering what protocol the Invader runs , Rx has a bind button .
Third , it be RTF ...

So , is it all good , bad or ugly ?
I guess thats whats interesting , what ?

THE Ultimate .. Goggles Battery Pack [Suprisingly Good / Suprisingly Cheap]

After using a few different FPV goggles, and different batterys I've found myself on the search for the best battery pack possible.


--
I've started out in FPV with the Quanum box goggles and FPV monitors varying from 7 to 10 inches in size, and used regular lipo's for them.

My first "real" goggles where the low budget Eachine EV100 goggles, I liked the EV100 and EV200D batterys, but did not like the short run time / price.
Later I upgraded to the FXT Viper goggle, and also got the Aomway Commander V1 - that I paticurly like because of the low weight.

The Viper needs a fairly large / heavy pack to get the unique box style type goggles to balance, so I bought the Fat Shark 18650 battery pack.
At that time I had the idea that would be the best battery pack possible, I already used 18650 Li-on batterys so while I found the Fat Shark holder fairly expensive I went ahead and started using it.

However I was still not that happy with it. It's a bit hard to push it in the Viper strap, I can't even use the battery indicator properly and for the Aomway I've found it way to large and heavy to my licking. Also the 18650 pack is not always that conveniant to charge.

Than I found these Quanum 2S 1500mAh Head Set batterys on Hobbyking, these works rather well on my Aomway, easy to strap on and fairly cheap to obtain a few. Runtime still not that great however, I've found myself...Continue Reading

This balsa cowl was made for a P-51B from plans (Aerofred). I had seen lots of videos on how to make a plastic cowl using liter bottles. Several builders encouraged me to haul off and buy a $25-$40 fiberglass cowl online. What?! However, I wanted a lightweight wood cowl that I could make. It took about 10 hours, but I used materials I already had on hand, so technically it was a savings. And it won't take me nearly as long next time.

Needed:
Rare Earth Magnets (from Harbor Freight)
1/8" X 1/8" stringers (mine were basswood)
1/8" balsa sheet at least 3" wide
F1 and F2 formers from 1/8" basswood light ply
glue / epoxy -- I used Extreme Power medium CA and Titebond II
You need to have your motor on hand to get the measurements and centering correct -- I used a Great Planes Mount and a Rimfire .46 motor

Context: This balsa cowl will go with a P-51B-D. (A has the guns on top.)

Tips to watch as you go through it.

1. Make F1 and F2 first. Get them glued with balsa between them. My plans called for 3/8", so that meant three 1/8" sheet balsa glued together.
2. Cut out a full-size F3 on the fuse and your front 1/8" balsa should be 1/8" smaller all around than F2. You'll want to sheet/plank the former to blend with the angle on the F2. Cut 1/8" notches about 1" apart all around the formers.
3. Tack glue temporary guides inside the rear and front ends. By tack, I'm talking a tiny drop of CA near the motor...Continue Reading

Since my last post, a great deal has occurred.
My family has now moved down to join me, and my flying rate remains quite high.
My mate Garry and I have restored a model SE5a.
The model was built by an old guy who finish the model but he never flew it.
He got sick and passed away. Over the subsequent years, about 9 or 10, the model remained in his garage, where is was damaged quite badly and gathered dust, until I found it in late May.
Gazz and I, mostly Gazz, repaired the model, and finally maidened this beautiful plane.
She is very heavy, not sure exactly how heavy because I haven’t put her on the scales yet, but, just guessing, I’d have to say about 5kg. This is very heavy for a model with a wingspan of just 1.5m.
We’ve installed a 580kv motor with a 100amp speedie.
To balance her, we had to put 300 grams into the nose under the engine cowl.
I’ll let the photos tell the rest of the story.
She is a handful to fly, and particularly land, but, a satisfying challenge. She now has 8 flights on her.
Oh, as a side note, I have phoned his widow and told her the model has flown and sent her pics of the model in the air.
Old Betty was genuinely thrilled....Continue Reading

Hi guys,
I am novice here (73 years) and I have the question. I am building SpaceWalker mini rc plane. I have the Flysky FS-i6X i6X 10CH 2.4GHz AFHDS 2A RC Transmitter. For my plane I need buy the Oversky MXL-RX62H V2 Receiver Integrated with Dual Servo for Frsky DSMX DMS2 FUTABA SFHSS - DSMX/DMS2.
My question. Can I use these structure? Can this receiver understand this transmitter?
Thanks for yours ansvers.

Want to say hi to everyone in the boat RC model circle and find other like minded groups here inaustin, tx.
My name is jack, have been a boat model afficinado (sp?) for 50 years or more, probably since high school 1957.
I am currently detailing the "Weisel" RC german patrol boat that I have owned since the 1960's purchase in 1965 while stationed in Germany.
I found the kit in the World's best boat and plane model shop, La Source des Inventions in Paris, France.
In the early 90's I had the boat in the water with one large graupner motor driving 3 props through a transmission. Found it was slow and low power to turn in
choppy lakes. So in 1994 was on a trip to France and went to the La Source in Paris where I had purchased the Weisel boat kit. They recommended using 3 Speed 600 motors which are now installed. Hope to find an RC boat club here in austin, tx with whom I can have access to local water sites.
Here is to happy boat RC greetings. jack charrin

The Depron Powered R4 DLG is moving forward .

Wing post and nose cone are done .
I just need to use some laminating film on the nose cone for a final weight .

Then I can move the wing post ( slides on the carbon boom ' at the moment ' ( ATM ) for CG .
So some ironing , and then some gluing . And the R4 should be cooking !



2nd 450x wing is in limbo right now as the 1103 motor did not work ...
So more waiting for a refund and the purchase of a new motor .

Disappointed that some hyperstall/microstall tendencies persisted in the B-Wing mk.2, I was about ready to hack off the leading edge of the wing to give it a sharper profile. In fact, I even ran some quick CFD tests of different leading edge designs to see if my extra-round leading edge was causing premature flow separation or other problems.

Quick KFm2 Leading Edge CFD test (0 min 50 sec)


While those simulations were running I decided to go out to my secret test location and run a few other scenarios with the Mk.2 to see if I could reduce the microstalling further.

First Flight: removed the AA battery that was taped on for nose weight (24 grams). Hyperstalling immediately exaggerated and a new 'diving' or 'tucking' tendency arose making it impossible to fly straight and level

Second Flight: added back the AA battery and added a second battery (total 48 grams) for nose weight. Microstalling 99% eliminated! No more tucking and no more bobbing in regular turns (only in very hard, high-g loaded maneuvers which is somewhat expected)


---------Flight Video---------
https://www.instagram.com/p/B1pv_1Ln..._web_copy_link


So for now, I suppose that ends the B-Wing microstalling/hyperstalling mystery... sort of. By changing from a KFm-2 Airfoil to a KFm-4 I saw a large improvement in flight performance. And then by dialing in the CG I was able to eliminate 99% of the remaining issues. The aircraft still doesn't fly perfectly, but that is something that can be tuned in over time (I can live with this considering it has been over 3 years since I built a plane!).

Next Step: Get my FPV pod v2 finished up and go for an FPV maiden

Yep Les Amis,
Ballade en Forêt, CINE"CAN" DO IT ! lol ... Voici un test que certains attendaient, le CINECAN, un des derniers Whoop HD de chez Eachine. Un peu déçu au départ à cause du léger jello en plein soleil (pas en indoor), puis j'ai découvert le filtre ND8 qui est fourni et qui réduit considérablement ce problème. Des images très exploitables, un appareil costaud et pas trop mal réglé en sortie de boite, au final un petit engin bien cool toujours prêt à filmer quelques cinématiques dans des espaces exiguës . En bref, je valide car pour 150€ (avec coupon), si on retire le prix de la Caddx Tarsier (75€) , Eachine nous propose encore un appareil à un prix défiant toute concurrence ! Bon vol et bon film à tous ...

Eachine CINECAN 4K - Review Test Démo - Beta FPV a de la concurrence ! (35 min 8 sec)


NOTATAZ : 17.5/20 Pas mal du tout !

Niveau : Débutants et Confirmés

I just had the worst FPV experience ever, and it was my first time out FPV'ing for real.

Situation was:

Emax TinyHawk Freestyle

FLI14+ FlySky RX w/ telem & FlySky Dark Knight NV Nirvana TX
AKK F3 VTX
Luminere Micro AXII (RHCP)
**************************************
FXT Viper 2.0 Goggles
Aomway ANT009 Diamond Directional and a Pagoda RHCP

I could not get more than 20 feet away without loosing signal all the way (mostly)

ends up this was the issue/s:

Had the +in going to the OEM EMAX VTX input pin 5v. ( really lower than the 7v min input req.)
It was in PIT mode.. ( learn how to exit out of PIT mode for your particular VTX)


Once I put the +v input wire onto the + lipo pad and got it our of PIT mode the image quality was awesome and I could actually fly it FPV.

Make sure to identify if you are in PIT mode , and do not assume your VTX runs on 5V

Other than that, buy a Freestyle and 20 batteries and have a blast, and email your fav battery charger mfgr's and ask for a 10 pack capable 2S 1AMP 10-port active charger with a wide range DC input. and within 2-3 months we should be able to buy that unicorn charger :-)
