Default "Starbee Light"

Fyi, I just noticed on Starbee's home page that hey! they have a new stealth addition to their lineup that is advertised to weigh in at 247#. As usual on the site, there's zero info, and just a tiny pic to pique the interest. But a perusal of the parts list indicates they've apparently made UL weight with a new cheaper and lighter composite tail assy, a tank seat, what looks like different mains, and something other than a Rotax engine--but they include an instrument pod with instruments. Interesting!

I wouldn't doubt that weight one bit! I wonder if the seat tank is lighter than the plastic jug?

treaze : the Ultralight has a MZ-201 on it. I was up there when he was building it. Looks ok!

Redbaron :
If you add the aluminum, jug, bolts and the fiberglass seat, it might add up to the seat tank......

True it is striped

The rotax 447 is 6 pounds lighter, you would hit 241 lbs

Redbaron :
I don't know what the weight is red.
Well I just report what was asked.......I think the MZ-202 is lighter than the 503 but not sure what the numbers are....

Yo Red,

We seem to be looking at different numbers.

MZ-201 (used w/StarBee UL) 69 lbs
MZ-202 (w/heavy gearbox) 87 lbs
Rotax 447 (dry) 81.7 lbs

Add a few ounces for the gear oil 82 lbs

The MZ-201 is essentially the same power as the 447, so I come up with the MZ being about 13 lbs lighter, not 6 lbs heavier than the Rotax.

I think the difference is that the MZ-201 Dana uses has the belt drive and the Rotax has a gearbox.

He gets a banana! I don't think Rotax even offers a belt drive for the 447. Although I saw a home-made one on a FW UL some years back.

I started out with dual carbs (like the 202), but belt drive (like the 201), and busted UL weight when I switched to the gearbox.

Rocky, how well (or poorly) did the belts hold up? Why did you switch to the gearbox? I ask because I'm considering that set up on the UL I'm plogging along on.

Pete my hirth had a belt! Its lighter but If the tension isn't just right the belt will slip, if its too tight its hard on the bearings! I like the gearbox myself!

Not well at all, but it wasn't designed for that combination. I was just trying to stay light. The poorest belt lasted almost 4 take-offs. A good Gates belt would last about 20-25 hrs only. Sport pilot came out then so I went that route.

I think a good Gates belt on the 201 would work. The extra horsepower of the 202 was too much for the belt.

Pete,

In Puerto Rico do you ever expect to fly over 1-2,000' MSL?

If not, the MZ-202 at 45 hp and the belt drive should work fine, especially on a light bee. The whole engine, ready to fly with the belt drive is only 69 lbs.

In the summer my density altitude gets up to 8,000 in the afternoon, so I need a bit more smash to fly. The 202 gets me around nicely at this elevation. When flying at Mentone or Bensen Days, performance is outstanding, and the bird and I are a bit heavy.
