needs a B&S v twin.....
WOW! That's impressive!
Mr. Barrows is one of the few people in aviation that if he says it will be 250 pounds, I'd bet it will be 250 pounds.

Its a thing now - and growing - Openppg - I no longer have mine but loved the design - PPG just wasn't for me.
Cant wait until we get solid state batteries and doubled capacity
Cheers
You can bet on that. His prototype 4 seat Bearhawk had a EW of 1195 lbs , from Bob. When I flew it I told Bob I would not change a thing. I loved it. Hated to sale my Bearhawk project, plans #276. The closest EW of any other Bearhawk that I know of is from a friend of mine in WY. His weighed 1238 lbs. A lot of that was paint and seats. Bob is one of the honest and nicest person that you will every meet. What he says is how it is.

I believe so, when Bob is ready. Bob wanted to built a legal ultralight , electric powered, and with enough wing area to work the lift on the nearby mountain ridges. Fly to the ridge with power and have fun with the power off and fly back to his field on electric.
I talked to Bob this morning and all is well!
WOW a Bob Barrows designed Ultralight!!
He gave me some numbers but I will wait.
Gotta subscribe to Jared’s Newsletter.
Bob seemed to think that the Briggs V Twin would be a good fit, so maybe he will look into it
Another bit of information is that Bob has recovered nicely from his crash. That was good news

Barrows is the man. Right up there with Rutan, VanGrunsven, Schlitter, Hamilton, and Wilson for living aircraft designers that get things done.
He is a Pro that likes .028!
Watching the video on YouTube, a little item on there is classic Bob, the intersection of two aluminum tubes, the miter of two 4130 tubes welded together then inserted into aluminum then pop riveted, this Ultralight is gonna be full of Bobs tricks!

R&B website isn't working now , but Bob still answers his phone and replys to his e-mails Bearhawk Parts from R&B Aircraft – Bearhawk Aircraft
I tnought it was decided batteries were counted in the 254 lbs even if removable. Lets hope the FAA comes to their senses on not counting battery weight. But thats an oxymoron.
or forget Epower and think O-100.
