Need pictures and ideas on where and how to install a BRS in my new (new to me) Kitfox IV-1050. Pls provide me details and contact info if possible. I'd like to leverage everyone's learning.

Thanks!

Here are some photos of the installation on my KF-IV1200 restoration project.

It's mounted behind the seat pointing down. It fires through the bottom of the fuselage. The lines are wrapped around the the right side and attached to the main spar carry-throughs.

Let me know if there are some specific views you want.

Thanks for these.... your location was just was I was thinking although it is pretty tight.

Can you give me some pics of your final install. Ideally need a close up of the bracketing so I can see how it mounts and where you pointed the rocket.

Thanks!

Is your header tank mounted directly on the backside of the seat?

I've got the seat out of the plane now, that will allow for better photos...

Yes, the poly header tank is mounted directly behind the seat pan.

I will take some fresh shots of the mounting later (football game is about to start. ) and put them up in my album for all to see...

(Too depressed by the football game. Thought I'd put some photos up.)

Here is the chute cannister mounted.

Here is the pull handle and the routing of the "wrap around" leads. This plane is a little strange in that the origional builder did not put the stringers down the side. If you do have these wood stringers installed, the "wrap around" would go behind the wood, hidden beneath the fabric rather that covered with a tape like this.

You might want to check out this ballistic chute discussion from a couple of weeks ago, if you haven't already:

It contains engineering drawings and a discussion about manufacturers.

Good luck!

Av8r3400,

Did you change the fabric below the rocket so that I can escape without disruption?

I did not build the plane, I bought it as a project.

As far as I can tell, nothing special was done to the fabric of the belly to aid or hinder the launch of the rocket.

BRS recommends a certain thickness to ensure that the rocket can penetrate without issue. Obviously it depends on what you have. For me, I plan on cutting a hole and replacing with a very lightweight piece of fabric.



Hate to see anyone go through the trouble of having a BRS, then need it, and it doesn't deploy right. That would be worse than not having one at all.

Thanks for all the help!!!

Jason ..you can perferate an "X" where the rocket ends up pointing with a perferating wheel ..looks like a pizza cutter but has teeth,.it's allot simpler way of preparing the deployment area and you have no evidience of it from the exterior when the finish coat of paint is on ....
check your hobby store ,,thinking I see them in there.
