Rotax 582 RPM

[DieselFan]

I repitched lastweek - at 90 I get 6300-6400 What are the risks flying bar in foot flat for too long and what is too long? Temps were 1100F, water 70C.

6800 is max rpm for no longer than 5 minutes

6500 you can stay at all day as long as the EGT is within limits

Min 950degF max 1150 degF

Hi DieselFan,

I'm curious to know as to how the re-pitching effected your inflight performance figures. (i.e. take off distance, climb, cruise & top speed and also at a later stage your new fuel consumption)

Thanks Morph, feel much better now

My take off is around 6000 up from 5500 (Manual said 5600 with my wing), I used to get around 600fpm two up and around 700+ one up. Now it's a hang of alot better around 900 one up, with two up at 700+.

Cruise one up is 4500 two up 4800. Can't say accurately for fuel yet as with the increased vooma I was gunning it and flying like a F16...still after 2 hours at Avg GS of 66mph (my cruise is 55). Fuel used was 23l used. She doesn't go over 6 in normal flight or climb, but with bar in at 90+ goes past.

Fuel appears to be more by about 0.5l.

One noticable diff was glide vs deadstick was more similar. Engine "idles" higher during flight now.

Hi all,

While on the subject of the 582, hoping for some help from the pros. I have an Aquilla 582 with a warp drive. Just had the AP and flight authority done which i passed.I have also recieved my flight authority. My AP tells me that my prop is worn and that i will need a new one Quote R7000. He has a new woden prop for me R4000. I am about to go solo and want to move to my kite. When i did a pre flight, i found a small hair line crack on the thin mettal sheeth that goes arround the prop before it enters the warp drive. Incidently, the school kite has the same crack on its prop. I realy like my instructor but cant help feeling that im been ripped.

Please expand on the "worn" theory. Sounds fishy to me.
If the crack is in one of the hub halves it is serious and must be sorted out.

Here is a post along similar lines. I would talk to Niren at Aviation Engines
