Must be something on your end. I just tried the SOH link, and it downloads a 16,966 KB file that opens fine. I also downloaded from Flightsim.com, with an identical sized file, just a different name.

The Flightsim.com one is the one that downloaded the small file for me, first, because I was interupted while finding my "save to" spot in my FS hanger. I get this often from Flightsim.com. I simply redownload, and it comes thru properly.

Which is correct. Having owned and flown a couple different ultralights, I assure you they do fly "nose down" to counteract the huge amount of lift in the wings. They are designed to start flying around 25-35 mph, most even slower, and the only way to counteract that lift is to reduce the incidence in flight. The most fun you can have, legally!

Great, thanks Don. It wasn't a problem, just one of those Hmmmmmm, things, lol.:salute:

It worked, just didn't like my down load manager..and wow this is fun. Thanks modelr for the help.
 
Can someone help me with the landing? The green arc goes down to 40 kts but I always get the stall horn at about 50, and the actual stall around 45 kts...

Therefore I have issues getting it down in really short fields.

Am I doing something wrong or is this what everyone else has?
 
Pretty close, when I did the dead stick landing, I was squeaking out every ft of altitude I could to get back to the airport and it seemed that at around 42kts it lost lift and dropped.:salute:
 
Well my observation about the MAI-890 so far.
I think it's pretty right on.

From my previous experience operating an ultralight, one tended to be concerned about temperature, altitude, and the especially the resulting density altitude.
Not being snarky here, but we all tend to forget sometimes.
Remember, your 'envelope' is a whole lot smaller than most general aviation planes in an ultralight.
You get a bigger margin of 'error', so to speak in a GA.

Flying an ultralight was all about weight and density altitude for me, way back when.
A real balancing act some days.
Sometimes in the summer, you just didn't have enough air left to work in by afternoon.
I'm sure advances in designs have made that a whole lot better. My experience is from 25 years ago.

But I noticed it yesterday, the MAI-890 was struggling in warmer, and very humid air at around 6000'.
The stall speed was definitely higher than indicated where I was at too.
I checked it at near sea level and it was operating just fine.

I believe Piglet made us a flying machine that will keep you 'honest' about your flying skills and operating within the old envelope, IMHO. :icon_lol:

I looked at the specs a few days ago on the manufacturers website and noted that they show the "service ceiling" as 3800m which works out to a bit more than 12,000ft. I guess if you're carrying oxygen that might be fine, but for the sake of a simulation, maybe you just needed to get higher? lol.
 
Besides me, has anyone noticed that the engine sound is a two cycle? and there appears to be a four cycle rotax four cylinder engine? BTW does anyone remember where that addon with a four cylinder rotax engine is at? Thanks.
 
Flaps???

One question - does the real deal have flaps? Piglet modeled his with flaps, but I can't seem to locate a site that states either yea or nay. Mind you, if it doesn't actually have flaps, this isn't meant to be a critique of Piglet's design. In fact, I've always been a huge fan of his models. I'm just curious. :ques:

Well the real airplane does not appear to be equipped with flaps.
 
The MAi-890 has no flaps, just full-span ailerons on the lower wing only. The Rotax's I work on at work sound very "two-stroke" like.
