  linkage stopper

I have encountered a problem with the linkage stopper supplied with my HK Sbach 342 EPP 3D 900 mm airplane.
Linkage stopper is the term HK uses for the metal piece used to adjust a linkage by tightening a screw, as shown in attached photo (this is not the Sbach, just a photo I had that shows what is meant). The stopper in the Sbach is attached to each aileron servo arm with a threaded rod nut; the problem is the nuts vibrate and come off. If you tighten them on movement of the aileron they cause the pushrod to deform, and bend the servo arm and horn .

I have decided to remove the stoppers and use a z-bend at each end of the pushrod, with the z-bends orientated at 90 degrees to each other. I am using music wire K+S 0.047, which I get from Frontline Hobbies Newcastle where it is stock item KSE-0502. The advantage is that there is nothing to become loose. A disadvantage is that if you get the pushrod length wrong you have to start again and make another - however with a standard z-bender this is quick and easy, and the wire is cheap and comes in 36" lengths. I was able to use both pushrods in my first attempt.

In the tail the Sbach has short pushrods for both the servo arm and elevator horn, that both go into a length of heatshrink tube, then adjust neutral position, shrink, then add cyano. This seems to be working OK so far.

I would be interested to know if anyone defends the stoppers, or uses the above method or other methods.

  UAV risks to manned aircraft

FAA require aircraft operators greater than 250g to register with FAA. CASA may follow FAA, and I have already seen noise about this in the media. This would apply to most of us plane or quads. Look at this article for some science on assessment of the risks.

Firstly a show of hands.

Who is interested in being involved in some FPV multi rotor racing at McCoy park?


Also post up if you have any objections or suggestions along these lines

Especially put up your hand if you feel that you might like to be the organiser/driving force behind making it a success.

Hi guys.I’ve received a deluge of emails pretending to be PayPal, so the other day I’ve forwarded one of the emails to their spam section on here is a copy of the email I received back read important that everybody reads it.

Here is there an email address to report any suspect emails phishing@paypal.com.au

Dear Bob Hoswell,
Thank you for partnering with PayPal to combat fraudulent emails. We take reports of suspicious email very seriously. Your submission helps us identify potentially malicious activity and take the appropriate action needed to protect our customers.
Did you know that approximately 90% of all email sent worldwide falls into the spoof, phishing, spam, and general junk category? By submitting reports of suspicious email to us you are helping to address this problem.
To help you identify suspicious email, below are a few things that PayPal will never do in an email communication:
1. Send an email to: "Undisclosed Recipients" or more than one email address 2. Ask you to download a form or file to resolve an issue 3. Ask to verify an account using personal information such as name, date of birth, driver license, or address 4. Ask to verify an account using bank account information such as bank name, routing number, or PIN number 5. Ask to verify an account using credit card information such as credit card number or type, expiration date, ATM PIN number, or CVV2 security code 6. Ask you for your security question answers without displaying each security question you created 7. Ask you to ship an item, pay a shipping fee, send a Western Union Money Transfer, or provide a tracking number before the payment received is available in your transaction history Any time you receive an email about activity to your PayPal account, the safest way to confirm the validity is to login directly to the PayPal website and review the relevant section. If you see suspicious activity, you would do the following:
1. Open a new browser and type in "www.paypal.com"
2. Log in to your PayPal account.
3. Click "Activity" near the top of the page.
4. Click on the suspicious transaction to expand the details.

  IMPORTANT SAFETY ISSUE

Posted by: secant0give

- Replies (8)

Please be aware that some receivers and this includes some FrSky receivers. Have a failsafe condition that means the receiver continues to output the last good received position signal to the servos. It appears that with some FrSky receivers this is also the default setting.
This may be the case with other brands of receivers as well.

If you fly fixed wing and your receiver has a failsafe setting it MUST be set to go to zero throttle in the case of a los of signal. I cant stress how important this is!!

It is also very easy to test. All you have to do is have someone hold the model, set the throttle at some safe setting ie 1/4 throttle and turn off the TX while it is running. The throttle should return to a zero setting in a very short time. If it keeps running RESET THE FAILSAFE so it does shut the motor down when the TX is turned off!!!

If your plane fails the above test and you have trouble setting the failsafe then please ask for assistance we will get it sorted out for no problems at all.

It's important because if there is a loss of signal from the TX then at least the model wont be fully powered up when it's uncontrolled flight comes to an end. It doesn't take much imagination to think of what might occur if it goes in at full noise.

If you know of or use any other receivers that behave like this please post up a list and also hopefully links to how to correctly set the failsafe.

Here is a link to the manuals list for FrSky receivers it's not difficult to set them correctly just find the appropriate manual and follow the instructions.

Hi guys. Here are some information on flight stabilisation systems.
I’ve thought about putting one of these devices in Bix 3. Because of the problems with the Bix 3 Pauling to the right and generally difficult to fly apparently I’m not the only one experiencing this problem, there are several systems available HK orange,FY-40 comes in several versions and including one unit with a GPS and several other units as well.

  Serious stuff!

Was at a utility convention in the US, and some of the exhibitors were commercial survey or UAV vendors.

The displayed commercial-grade equipment was incredible the chopper in the pics was powered by fuelcells, and would fly for hour. The pic of the tv screens, is a shot inside a large van used as a mobile surveillance command centre. Basically this thing rocks up to say a school shooting (seriously, that was the example they used!!). A 40foot extendible pole comes out the top of van, with aerials, tv cameras on it, it launches a handful of multi rotors all with hirez cameras, that go to fixed locations/alt and become viewing platforms. All the video comes back to the screens in the van, so within 10mins of arriving on scene every angle they want is covered, the tech and video quality was amazing. most of the multis could stay on station for 45-90mins, single charge. The left most one on the table (pic) guy said could operate in upto 55mph winds and was worth about US$70k... serious tech!

  Air Racing Dates for 2016

I thought I would start this thread for all the official racing events this year and put them all in the one place.
So if it's to do with NSW pylon or Large Scale or Quad racing post it up here!!

Here is some info recently to hand about the Large Scale racing this year.
Dates and places for the events and some changes to the rules


Hi Guys,

Just thought I would give you an update on the coming 2016 F1 Air Race season.

Latest info is on the following web site
http://rcmnewssjg.wix.com/rcm-news-f1-air-race

Note: The class names have changed slightly, again. Essentially add 1 to what you thought you were !!

F1 is now a new class for 35% scale aircraft with tuned pipes etc. No ARFs allowed !! These should be pretty quick models.

F2 is the old F1 for ARFs such as Nemesis, Cassutt and Sundowner. 56cc engines can continue to be used with any prop. Nemesis and Cassutt will be allowed with up to 63cc engines due to limited supply of smaller engines, BUT there is a prop pitch limit if used in a Nemesis. Currently this is 12" but it may be revised over the year to try and ensure parity with the 56cc engines. I would think that it may end up at 13" but we will have to see.

F3 is the old F2 for Nemesis with up to 35cc engines and 8500 RPM limit.

Red Bull is the same except there is a new Wingspan Minimum of 1650mm. This is a few mm under the Seagull MSX-R making all current planes legal I think. It doesn't say it yet, but I believe it should say that the external shape may not be modified.

Dates - This is what I believe but nothing is set until it is published

19-20 March Darrawit Guim (Vic State Field)

Bairnsdale has been canceled 2nd- 3rd of July Bairnsdale (date has been changed from the 11th and 12th of June)

20-21 August Bendigo

15-16 October Canberra

Anyhow, best get building, repairing, modifying and practising as the first race will be here in less than 8 weeks.

Cheers,
Jeremy

I am migrating across to a Taranis... and have an orange tx module for my DMS/X receivers. I will of course range test before first flying each on the new setup, but does anyone know if the transmit power of the orange module is same/similar, hopefully not less, than my dx7s?

For Sale - a crashed Bixler 2 with all repair parts needed.

See: http://forum.rcflyingclub.com/showthread...2#pid23922

I haven't been able to return to the hobby since this crash. I ordered all the spare parts after the crash so everything should be unused.

Included are a few spare batteries, spare parts I accumulated, remote control, receiver, everything!

Pickup in Toongabbie or Olympic Park (where I work).

Make me an offer!

Mob ph: Oh four two two one one seven six two six.
