Trying to get some good sense and safety incorporated into an event here. Does anyone know of a currently available commercial made shut-off. I thought MBS had one but it's not shown in their catalog.
Thanks

Contact Bill Bischoff.

THANKS!
Do you have a contact #?

I have always preferred to make my own, tailored to the airplane.
The only finesse issue is grinding the notch halfway through the 3/32" piano wire.

home made isn't what I'm looking for although I have always made my own as well. I want one that anyone can go purchase. I thought that was clear in my request. So far, Brodak seems to be the only one?
Thanks

This shutoff is very simple and trouble free. I sell the bent wire for $1.00. The other part is a modified 1/2A control horn. It only takes a couple of minutes with a Dremel cutoff wheel to make.

thanks Bill.
I have put through the rule change proposal to include the shut-off and if passed will do a small write up of shut-off's and include yours. It's always problematic when proposing ANY change to existing rules so now the whining can begin.
Thanks again

Ken, you are welcome to use/ reproduce any of the above images. Good luck with your proposal.

Nice photos, Bill. Do you rig it to the up or down line? I thought I should ask the man with experience. I could see it working OK either way.

The shutoff trips with down elevator. If the control system is on the outboard side of the plane, the elevator horn should be mounted on top of the elevator. The shutoff cable can either connect to the horn or the pushrod. If the controls are on the inboard side of the plane, the easiest thing is to just mount another control horn on the top of the outboard elevator.

If looking for a commercially available shut-off, Fourmost Products makes one similar in operation as Bill B's. See: http://www.fourmostproducts.com/our-products/fuel-fittings/ (http://www.fourmostproducts.com/our-products/fuel-fittings/). I have used this in an R/C set-up but not U/C.

Thanks Norm. I had completely forgotten about Foremost. I brings back nightmares of the years we spent trying to make shut-off's for fast combat.

what ever u do ,don't ever ever
put the shut off on the UP LINE.i can GARENTEEEE that at the worst time u will need to give full up and trip it usually nose up and no air speed.
I have flown 3 planes with the shut off on up. I hated all of them
-
I'm confused. Is this about buying, making, or a rules change proposal?
If it's a rules change, what is it? If it's requiring shutoffs on ALL racers, it won't bother me, but it will squeeze out some others.
The merits of shutoff in Combat can be defended, but the rule squeezed out so participation.
I bought some Russian F2A shutoffs. Good workmanship. But like all store-bought shutoffs, you need to engineer the model to fit the shutoff.
