Default UUUggghhhhh

I just noticed on the plans that F-711C gets tapered for tri-gears. Why is this? I don't see it getting in the way of anything.

Anyone?

Thanks,

Tom

Default Darn good question

Tom, hello, good question. I don't see an issue other than
a little extra weight. Curious myself to why it would differ from
an A model to a tail dragger. Check in with Vans. I seriously doubt
they suggest you change it.

I'd guess that on the TDs, the lower parts of the bars are used to anchor the tailwheel spring socket, so more strength and therefore more metal is needed down there. Or something like that.

Thanks, Bob K.

I don't have a good answer for you but does the tie down block need to fit between the two. If not it must be weight.

Thought it might be for weight reduction - I'll shed is someplace else.

Thanks,

T.

It's difficult enough to find opportunities to remove weight from these airplanes. I'd suggest that you taper it per the plans.

On my RV-3B, which is a much less pre-shaped and pre-drilled kit, the similar parts needed tapering. I marked it with a Sharpie, cut OUTSIDE the line with my bandsaw (using a 14.5 tpi wood blade, cuts like butter), filed it to the line with a Vixen file, and dressed it with a fine mill file. Took only a few moments.

Go for it.

Dave

Looks like I tapered it for my -9A.


If you are ever going to do a tail wheel conversion, leave the extra material!

I'm sure that's why the QB has the extra material.

Default tail wheel

doesn't the front tail wheel leg bracket tie into those on the bottom? i can't recall for sure, but that is what it seems like!
