I see that Dan had his hands full again with the big Bi-Slob. Dan told me about it last year but it was not ready for prime time.
So what's the story?
-
I watched it fly on Friday. It is throtled so he can make it hang and he was doing some stunts with it. quite an impressive plane...

What engine does it have ?
How is it throttled, I dont see a 3rd line ?
How much is it scaled up from the normal Slob, and what is the weight ?
-
I'm sorry, I don't know the answers to that. Possibly they will be on SH and give a bit more information...

Dan uses the Z-tron on his wrist to throttle. I believe the engine is a Supertigre 3000. The engine has a custom muffler that has been quite a handful. The original was far too heavy and the new custom underwent some breaking during the experiment stages. I'm glad it held up over the week. Dan had mentioned that during the hang, the nose is pointed up which was presenting a few problems with fuel draw. At the low speed and nose pointed up the engine wants to lean up causing erratic running which usually results in the engine speeding up without him throttling. He seems to have a fix for it. The prop is 20" and its quite a finger biter when starting initially. There were a few minor adjustments prior to Brodak's in which all of them seem to make the flying even better. The throttle is hooked to the rudder helping to yaw the plane out. Aside from some leadout adjustments and more tip weight the plane flew great. Ken

The critter unscrews to travel.
Danny is switching to a Perry carb.
It is a 2 CI gas engine, I believe.

BIG !!!!
Alan Buck's Grandson Xander trying it on for size

The slob is twice the size of the original.
The Super Tiger 3000 weighs 42oz without the muffler and turns a 20 x 6 prop.
(The ASP 1.08 from the Flight Streak would barely fly the Bi-Slob. It couldn't even climb to the top of the circle with the 1.08!)
The weight is unknown, but it is probably in the 12lb range.

Doubling all dimensions actually makes a plane four times the size (volume) of the original. (Or is it eight times the volume, since there are three dimensions being doubled. Perhaps someone proficient in HS math can offer an opinion.) The engine required is double the size of the double dimension Streak. As for subjective impressions. It looked like Danny, in order to overcome the pull of the BIG SLOB, had to tilt himself even further from the vertical than he does when flying the Big Bad Black Streak. Amazing. Since the Big Slob flies slower. There's a throttle control using Windy's infrared device. The throttle control simultaneously induces Big Slob amounts of rudder offset. Prop hanging is almost happening. Loops are tiny, scary, a threat to all. The slob flops and jiggle juggle back flips are spectacular and alien. It's the scale... the size... too big a bird to fly loosie goosie. Th BIG SLOB IS A THREAT TO ALL! Kudos to Dany and Ted for putting another notch on the tree of ultimate weirdness.

When we published the "Slob" we never anticipated that we were spreading a disease.
I think Dan was the first to build one after he saw mine. He was the first person that I flew "Double Slob" with many moons ago.
But, I am afraid that Dan's strain of the disease is incurable! The white coats are looking for him.

I saw a sketch of it in a ancient magazine, ::)
Was it two flite streak wings with a cardboard fuselage ,
or was that a tangental reality ? ;D
Aye , four times the area , eight times the displacement.I think .
Check by putting it in a bath , like Galelao , or Archimedies , or was it deVinci .
Dont go running out doors in a hurry though, remember modesty is more befitting.

All of Ron Pavaloer's "BiSlobs" had corrugated cardboard fuselage sides. We published it with balsa and 1/32 ply doublers. My Slobs have all been balsa with the plywood doublers. I had also seen the picture years back stating that it was based on the Flight Streak wing. Ron did not confirm this when we did the Flying Models article. Certainly, the trailing edge construction is very different from a Streak.
