Flying the Valley Engineering Back Yard Flyer UL

Here's a video of the new Back Yard Flyer from Valley Engineering with its four-stroke Big Twin engine. Remember, this is a part 103 LEGAL Ultralight WITH a four-stroke engine, starter, alternator, battery and individual toe brakes. Not only that, the wing swings 90 degrees for storage... in less than 5 minutes.

The take the original 40 hp and up it to 50 with a lot of internal changes and new cam, carb, heads, pistons and other stuff. Hell of an engine and FOUR STROKE.

[TheWisey1234]

how much do the cost.

[dstarks1943]

@TheWisey1234 @TheWisey1234 It depends on how you want it. With or without custom trailer. Either way, the plane comes complete ready to fly. No construction needed.

[TheWisey1234]

do you need a licence for one

[dstarks1943]

Nope.. as a legal ultralight, you do not need a license to fly this plane. BUT... Anyone thinking of doing this SHOULD TAKE SOME LESSONS FROM A Certified Flight Instructor. I can't emphasize this enough. Just like the quote from the test pilot that flew the first Piper J-3. "this plane can just barely kill you." No matter how slow they fly or how light they are, they can still kill you.

It looks like a 1/2 V WW and that would be legal .

[dstarks1943]

@dochelp1m

Actually it's a Valley Engineering Big Twin. V-Twin, 4 stroke, 40 hp or you can upgrade it to a 50 hp.

Welded aluminum takes maintenance like all planes. Rivets get replaced, wood rots, steel rusts. Just part of owning an aircraft. Maintenance! Just sell ready to fly. No kit.

price for kit?

@cmartman48 what is the solution do you suggest?

[cmartman48]

I notice a real thick airfoil towards the middle section where the prop air flow is.

My main concern is the welding. Not if ! but when ? welds will crack. Any porosity will eventaully give way to corrosion which will cause premature fractures. Anything that vibrates will cause cracks, gauranteed!

Crack= crash and burn!

@dstarks1943 Is that a single-pin crank, I wonder? I thought I heard the engine doing a "potato-potato-potato" like a Harley. Impressive. BTW, how's the Taube?

@0851481111 25.000 - 30 000 $

It depends on motor, I mean what motor you wanna use and do you want it with trailer or not. It's not so cheap if you think that you can buy it easy.

[Mr2Waren2]

how far can it fly?

[gunnersdoubleott]

@dstarks1943 How is the 50 hp upgrade accomplished? Is it the same engine just tweeked a little?

Looks like a great set up.
