ILS Approach for Arducopter (5 min 31 sec)

The recently released Version 3.2 of my GCS FlightZoomer (for ArduCopter) offers an automatic approach system, that is similar to the ILS for manned aviation. For plane it was working since last year but since copters can't just slip down the glideslope and then touch down with a lot of forward speed, the implemented procedure had to be changed as follows:
Name: ILSCopter.png
Views: 0
Size: 33.0 KB
Description:
❶ At first, Copters will stay in GUIDED mode and will descend on the glideslope towards the runway.
❷ The moment, when an altitude of 7m above ground will be reached, the descend will stop and the copter will continue in level flight until the begin of the runway is reached.
❸ At that point, forward speed will be cut to zero, and the FlightZoomer autopilot will put the copter automatically in ArduCopter's LAND mode.
❹ The ArduCopter LAND mode will then simply perform a straight down descend.

As you can see in the examples in the video (towards the end), the whole procedure provides stunning results.

Some more bullet points about ILS approaches for copters:
  • As any number of runways and glideslopes can be defined upfront in the FlightZoomer navigation database, the airspace can be structured to support flexible flight operations in changing conditions (different for plane vs copter, have runways for different wind directions).
  • The final descend can start in a controlled manner at a rather high altitude. There is no need to for a long descend in LAND mode.
  • Solution picks up terms and procedures of manned aviation.
  • The procedure does hardly deviate from the solution for planes (the only difference is the short vertical descend right before touchdown).

Plan was to CG all 3 new planes starting with the F959 .

Unfortunately just after I was done with the F959 , there is a rain front moving in .

F959

I was expecting all sorts of nasty things , but to my surprise the F959 flies like a bird .
There is one thing it wont do = Turn !
At the very slow chucking speed for CG testing , the rudder and elevator were super soft to non existent .
I did apply just the smallest amount of throttle , maybe 10% .
And the F959 actually flew in a straight line with so little power and maintained altitude . But that soft elevator rudder !
Obviously to get more authority , more speed is needed .
Now , how slow was I flying ? A fast human could easily outrun the F959 .. ( So slow )

Obviously with the F959 so soft on the controls I had to move the battery further back ..
To cut a long story short , I moved the battery almost all the way out from the space where it is supposed to go ..
And it was still soft on the controls , exhibiting no instability what so ever .

I dont know that I have ever come across a model with such a wide CG range .
But it did turn better for moving the battery at such slow speed .
I am going to have to velcro the battery so I can move it further back ..

Hmmmm , at 111 grams flying weight .. And the CG being able to be moved back ..
I wonder if I can pull 12 grams out of the nose ? and make the 959 a true sub 100 gram model !

I really wanted to CG the Ezio and Firstar today as well .. But I dont want to be caught in the rain .. So another time !

Spektrum technical recommends:

1. Start with a new model and not an existing model.
2. Bind it with the bind plug removed. Make sure receiver is blinking when you bind.
3. In System Setup Channel Assign assign a switch to turn SAFE on or off. Any switch can be used between channel 5-9. The gear channel is 5. If the gear is used for retracts then use channel 6 to activate switch B. I like to use Switch B because it’s the easiest to toggle on and off with the left forefinger pad. The middle position (1) can be set to On or Off.
4. Move both sticks to lower inside position. In the monitor screen make sure throttle, aileron, elevator, and rudder are showing plus or minus 100 percent.
5. Toggle switch B between stops (0 and 2) until you see a “twitch” in the elevator. Stop toggling when you see this and confirm the switch works by holding the model nose down and tail up. SAFE On should give you up elevator. Turning it off should give you neutral elevator. Put model into a bank. The upper wing aileron should raise trying to level the wing. If you don’t get this re toggle the switch again.
6 Once the switch is working you can name the model, select wing type (flaps), throttle, cut, rate switches, mix switches, and audio.
7. On first flight turn SAFE Off and trim the model at what ever minimum power is to maintain altitude (roughly 50 percent throttle) then land. If FM (flight modes) are used then trim for each flight mode such flaps up,...Continue Reading

Making my own wheels has been an interesting project. Using layers of balsa and basswood ply has been a challenge, but theirs texture looked like tread. The last part was building a "receptacle" into which they can fit inside the wings between #4 and #6 rib.

I've made my own plans on this. And except for pinching my thumb and later my palm with linesman's pliers working the 1/8" wire, it was relatively painless and full of good sanding effort.

The wheels were rattle can spray painted with Testor’s flat black and I used clear flat matte spray lacquer on the finished wheels for protection and durability. The hubs were dry brushed with Testor’s silver enamel. They were affixed with Gorilla Glue 5-min. Epoxy.

The Apollo XI field has been around for about 60 years. New legislation signed by our president gives the FAA new power over RC flying they did not have before.

Affective May 24th 2019 the FAA suspended operations at the Apollo Field pending review of the local airspace and operating procedures.

Test Flight #3 - Ranger G2 with 8X4 Prop - Loops,Rolls, & Flaps Deployment ;-)



Here is a link to the Video:
https://www.youtube.com/watch?v=CcZh1ZxiZ10

After performing the Motor Thrust Angle MOD on the Ranger G2 it gave me space for an 8x4 Prop.
I removed the stock 7x5 Prop to conduct some Test Flights with and 8x4 Prop.
This should produce significantly more thrust than the stock 7x5 Prop.
I have this plane trimmed out pretty well now ;-)
I have increase the Airleron from 100% Scale to 110% Scale to give a bit more Airleron authority.
I think I like that additional deflection on the Airlerons.
I also programmed some down Elevator with the Flaps to keep the plane from nosing up when Flaps are deployed.
Let's see if that helps.
So let's go do some Rolls, Loops, and Flap deployment ;-)

Yep Les Amis,
Silence ... ça tourne !!! Comme je vous en avais parlé récemment, j'avais craqué pour cet engin et l'ai commandé directement chez iFlight. Voici donc enfin ce fameux MEGABEE ... Un 3" inspiré du shendrone squirt v2 entièrement assemblé par iFlight .Bien conçu, costaud et des finitions très propres, ce petit racer vous permettra de faire des prises de vue tout en douceur, en mode stabilisé ou en acro, dans des endroits confinés en intérieur ou en extérieur, afin de réaliser de jolie cinématiques couplé à une bonne caméra (normalement prévu pour la Gopro 7 Black) . Bien équipé avec sa Tower SucceX F4 V2 et sa caméra FPV Caddx Ratel, il est très maniable et hyper stable grâce à ses protections d'hélice qui lui servent surtout de conduits d'air qui lui confèrent une poussée supplémentaire . En bref, je ferai bien sur d'autres tests sur cet appareil, mais pour l'instant je suis très content de ses performances . Bon Film à Tous

一般的にはrc潜水艦のwtcはアクリルパイプで作られているようですが、WWII時の潜水艦 は細長くて
前後共先細り、しかも小スケールモデルなので、サーボも入らない細いパイプしか搭載できず。
なので、FRPでハル内側に沿ったケースを作ることにします。

上部ハルの天井部分には5㎜の隙間を開けて、水と空気が入れ替わるスペースを作ってみる。
wtcに十分な浮力が出来れば、浮上した時に喫水線を下げることが出来るのではないかと予想。
浮力が足りなければ、浮力体のスペースに出来るし。

上部ハルには5㎜厚スチレンペーパーとバルサパテ、下部ハルには石粉粘土でキールとモーター部 を
カバーする。マスキングと、pva(洗濯のり)を3回重ね塗り。

樹脂が足りなかったので下部ハルだけ作業した。今回はサフェージングマット1プライとガラスク ロス
4プライでやってみた。

I tried to whole “let’s print an airplane “ thing again. This time it’s an ECLIPSON model T. I really had to add the nose ballast on this one. Flight weight is 930g, about 100g over ideal. I’m just hoping that the plane will hold up to the stress of flight. The quality on the parts I printed isn’t great.
