Ninjalock- Throttle safety harness

Reading through the forums one day I saw a picture that a guy had posted with a rubberband holding down the throttle stick. I thought to myself "That looks stupid!" The next day I bumped the throttle accidentally and flew the airplane out of the back of the car. I started using the rubberband trick from then on.

 That was version 1.

Version 2 looks a lot better and I don't have to replace it every couple 'o weeks. If your radio doesn't have a safety option for the throttle, feel free to copy or improve the design and make one of these for yourself and your friends. Just let me know how it works out for you.

One piece of sewing elastic

Two pieces of shrink tube

One O ring

A little bit of hot glue

One end of the elastic is looped around the handle on the back of the radio, hot glued to itself and then the shrink tubing keeps it secure.

The other end is looped the same way and looped through an O ring.

Hopefully the pictures will fill in the blanks.



 

Fly safe-

Don't let this happen to you!

Hi, I use throttle cut with my Helis all the time... Of course I do, with Helis you always do. But I also have planes. Started fiddling with the t-cut settings and got nowhere. But hey, why make it so difficult? Take the switch you wanna use and mix it to the throttle channel... "when switch on, throttle 0%". Never had an issue again. Of course, when you switch the cut off, what ever throttle setting you have kicks in. Then again, at that point you SHOULD already be paying attention.

just to specify: when switch on - throttle curve = 0 all the way.

Sounds like a good idea for an article!

Hi,
I changed my DX6i "Trottle Cut" button to a switch, now I can
use it as a safety option for the trottle (see into the DX6i menu to activate it).

However, a issue may happen with some ESC, that can
learn the Trottle cut position as a new Trottle zeroed position (if you switch on your ESC with the Trottle Cut set). The Trottle Cut works, but the ESC starts at full speed once you release the Trottle Cut switch.

This issue seem to not happen with Turnigy Plush edition (but do with Hobbyking SS serie).

Hope it may be usefull you,

Overlander

Hi Overlander
So, did you actually remove the button and replace it with a toggle switch?
Sounds like an awesome hack.
Have you documented it in a blog or an article somewhere.
Sounds pretty useful for those that are willing to to a little soldering etc.
Thanks for the comments.

Ouch!

This is one of those things that, once seen, is so obvious that it is ingenious! I'll be adding one of these to my Turnigy. My neck strap often engages the throttle unexpectedly. Fortunately, no appendages have been in harm's way. Its only a matter of time, though.

Yeah- OUCH! That one was my hand. A friend had cut his just a couple of weeks before- even worse

Talking to some of the guys at the field and I guess this is a common practice to do something similar to this in the DLG community. They'll take a rubberband and use it to keep the stick in the "up" position.
I think because they mix flaps in with the throttle channel...

Now that I read this article, I can't not do it. Only have myself to blame if I or others get hurt due to accidental throttle advancement.

That is a great idea. Sorry that you had that happen to you. Thanks for sharing.

Yes, it was a hard way to learn a lesson, but lesson learned!
This also caused me to re-evaluate my flying wing launch method.
A great motivation to learn one of the side arm launching techniques and a reminder that complacency can be truly dangerous.

Hmmm... need to revisit this. I don't have this on my transmitter at this time.
Maybe need to create an updated version...

Watch a guy's airplane try to fly out the pits the other day. Reminded me of these things.
