Valley Engineering (Backyard Flyer)
USA Part 103 Buyer’s GuideValley Engineering
The Backyard Flyer folds, and the same shop turns your propeller. Valley Engineering builds the folding-wing Back Yard Flyer and is the source behind Culver aircraft propellers. They publish no price we can compare, so we grade them unrated.
2BUSINESSES, ONE SHOP
The aircraft and the propellers come from the same people, and the contact details are cross-listed on the Culver Props site. Useful if you want both. Confusing if you do not know.
Published today: no price. Contact for pricing and specs.

The lineup
One Part 103 design.
Folding wing, tailwheel, open cockpit. Specs on request. Ask about the Culver propeller while you are talking to them, since it is the same shop.
This listing is thinner than the rest
We have not finished verifying Valley’s engine options, kit tiers, or weights against their own site. Rather than fill the gap with guesses, we left it empty and told you.
Who it suits
- Pilots who need folding-wing storage from a small, builder-focused shop.
- Buyers who also want a source for aircraft propellers.
- Hands-on builders comfortable dealing with a small operation directly.
What you give up
- Smaller company, so lead times vary and support is one or two people.
- No published pricing at all. Every conversation starts with a phone call.
- Contact details live on a second site, Culver Props, which is confusing the first time.

Part 103 compliance is yours
An aircraft marketed as Part 103 capable can exceed the 254 lb powered empty-weight limit once engines, instruments, and options are added. You weigh the finished vehicle and you confirm compliance with 14 CFR 103 before you fly it. See the Part 103 disclaimer.
Are you Valley Engineering? This listing is free and independent, and right now it is thinner than it should be. Send your model list, engine options, and kit tiers through the contact page and we will fill it in. The free listing is not conditional on any paid engagement.
Your buyer just configured an airplane. Could they do that on your site?
Built by Christopher Eller. If you build Part 103 aircraft and want this on your own domain, with the leads landing in your inbox instead of ours, that is the whole job and I do all of it.
