B-70 Valkyrie (oz6639)
About this Plan
B-70 Valkyrie. Profile scale delta pusher model.
Quote: "A Bob Linn design. B-70 Valkyrie. A high flying model of the US Air Force's newest, fastest, highest flying airplane. The world's first true nuclear bomber. Now in production at Northern Aviation ...dozens of these B-70's have been flown with .020 and .024 size engines, this power is adequate and the flight pattern realistic, however if desired, engines of up to .049 displacement can be used if tank is used as engine mount."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsGood Morning from Oklahoma Steve, I built and flew one of these B-70’s with an 0.020 for power back in ’75 while an Aero Engineering Student at Parks College of St. Louis University. Two things I’d like to share: One it’s a three foot long flying SPEAR! Make sure it’s not going to come down anywhere near other people. Two, launch it level, NOT nose up. The wing can and will blank out the rudders. So what you thought was set for a nice turn will take off in a straight line in the last direction it was pointed in. Other than that it was a lot of fun!

I flew a Competition Models B-70 back in the mid 1960s that was built by my dad. It flew nicely on a Cox .020 reed valve engine and was eventually lost OOS in a thermal. I've been looking for a quickie, all sheet project for electric power, and due to the nostalgia value this one holds for me, this will be it. A sincere thank-you for making this plan available and the memories!

Back in the early '60s my Dad and I built one of these with an .049 on the back. We flew it several times out at Rosamond Dry Lake not far from Edwards AFB. Being a delta it was fast, glide ratio un-powered was pretty steep, but it sure looked neat in the air!! Like the previous commenter stated it was a bit of a powered dart so I had to make sure everyone was watching whenever we launched it. Thanks for making the plan available, I can't wait to make another one!!

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
