Nothin' new under the sun.... https://www.rcgroups.com/forums/show...&postcount=437 The pusher JBug was a nice putter around the gym flyer at 20" span (or was it 22?) But i do like your vdub theme! And even if you just glued some clear plastic to inside of windows i bet it will strengthen the fuse a ton!

I bet that the JBug could be tricky to balance. Not much room forward of the CG. Your right about the windows also.

It wasn't all that bad, since it weighed essentially nothing and even the tiny battery moved a bit easily affected the cg. The Large nose pusher type planes are fun to watch fly, I expect yours will be a hoot!

Those Overhead Projector Transparent Laser printer sheets "from Work"
make pretty good windows and they are thin.

Too bad I don't work anymore ( yeah right ! )

I also have some fairly thick clear plastic for Vac Pulling but I just never get around to that
Sooo ! I may use a piece to cover the whole front of my Beeker.

Mike, I always tend to gravitate toward the unusual in my aircraft "likes". Hopefully it will bring a smile to the faces of those who decide to build one also.

Anticipating to maiden the Beeker Saturday morning, if the weather cooperates. Showers here this morning. My son will be able to video for me Sat morning, so I hope to have something up very soon!

Sorry guys I punched the wrong button
I scaled the airplane from the 2x4 sheet of foam board
and came up with a wing span of42.750
this should be a real floater with an under cambered wing

I thought so myself.
hence my comment about an indoor version sometime b4 Fall.

The designers' dimensions are in the 1st post so I guess I got pretty close, eh :-)

But, the original designer, cbalgra , did a built up wing.
Then again my plans only have a single sheet for each side of the wing.
If you want to cut another and laminate up the spar and curved top sheet It could become a
faster speedier , maybe even aileroned plane.

I suppose one could put whatever kind of wing they want on the platform.

It'll look good against the back drop of Mt Renier !

I'll be doing a test CNC Cutting tomorrow.
That's a check plus I'll have parts for myself :-)

I'm thinking that since it's going to require 2 full sheets of MPF
that I'll be able to offer it for $36 + Shipping.
That's Just the Cut Foam Parts.

Yes as I posted earlier, this was an old design. The plans I have is almost exact as the OPs design, rounded nose and all.

AS promised I have done a test cutting and all went well except for the Fin,
which was not cut for some odd reason.

See pix please.

Not much to complain about here ;>}

edit l8r:

Fin fixed and formers narrowed as they were designed without
consideration of the Doublers. Otherwise not too bad so far :-)

Bob, that looks outstanding!

The only difference I notice, is that on the prototype, the nose didn't get pulled all the way together. It was done to allow a larger battery to be mounted as far forward as possible to adjust CG. I have a 3-cell, 2200mah batt all the way forward to achieve balance at about 28% of chord.

wow really ? !

Well I'll have to wait-n-see how this one goes together.
Could be I'll need a serious Nose skid( weight) eventually.

Or maybe put the pak on the outside just to make it UGLIER than a Vdub :-} NOT

Good luck tomorrow.

Best
