O-ring on Spark

[IPedro]

I heard that you can put an o ring instead of a battery clip to protect the spark battery from falling. How do you fit a #141 o ring in the spark? How does it work? I haven’t found any video on YouTube explaining anything about the o ring. Can anyone help saying everything you know about o rings on spark please?

This is an example with a rubber band.

The O ring works well.



You may have to remove the props if it's too tight to stretch around the motors.

I had one of those but prefer to fly with prop guards on and the one I had wouldn't let me do that.

I modified my clip with a Dremal took so it would fit along with the guards but with repeated use it broke from not having the structural integrity before I modified it.

Rather than purchasing another one, or one that may work, I went with the O ring and so far so good.

If you have the new type batteries you dont need anything. There is a post here showing the difference.

I use a clip and are happy with it. I wouldn't use an elastic band because they are prone to breaking with age. A elastic band could flip up into a prop and bring your spark down. An o ring would be more durable

An o ring would be more durable

I agree.

The picture I used was an example of how to put the O ring on.

At the time I took the picture I was using a clip and not the ring, but now that my clip broke from being modified to fit with the prop guards, I use an O ring.

So - what size o-ring and where to buy?
I use the clips but every single one I've seen has a sharp inner corner that will eventually fail from stress.
Yes - I've had two fail so far. They should have used a radius on those joints.

They list three different materials - anything specific? I'm figuring silicone for stretchability since the other two are listed as medium hard.

The ones I got were standard buna 90?

I got the silicone and couldn't be happier - perfect for the Spark. It's even easy to move out of teh way to swap the battery.
Perfect! Thanks for the referral.
