Can anyone tell me what the maximum static rpm should be for a Rotax 582 in

a Kitfox lll. Also top rpm on take off?

I turn 6,500 at 55 MPH during climb out......  I talked to  Lockwood....  a 

fine Rotax outfit, they say I should be at 6,700 and see a  big increase in 

power.... I have to tell ya... it scoots at  6,500..........

 

Good luck

You need to check the accuracy of your tach first.  My Westach is off by 

300rpm at the high end and it varies with temperature.  I check it 

everytime I fly with an optical tach.  You can easily be over revving 

the engine or not producing all the power you are entitled too.  Once 

you are certain of the tach's accuracy then follow Lockwoods 

recommendations.  They know what they are talking about.  I like 6500 

static for my climb prop, and a bit less for the cruise prop and use 

6700 rpms as max.  Cruise is any where from 5800 to 6000 rpms depending 

on my mood.

If you have a GSC prop, I believe they say no more than 6200 static...I 

don't think I've ever been below that myself, however

I just talked to GSC and they told me 6200 max for there prop but I don't  

know why. You can adjust it for cruse verse speed.  I have been worried  about 

my 3to1 gear ratio Ebox and a 3 blade prop any thought on  that?

well yes at 6,200 your way down on HP.  I used to be at 6,200  went to 6,500  

wow, huge difference...   and these two  strokes like to spin...  less 

internal stress...believe it or not... I was  told.,on a KF 1,2,3  regardless of 

prop gears etc, you need 55 MPH  climb at 6,700 WOT 1,100 EGT on a 582....      

now,  503, that's different depends on 1 or 2 carbs.....   in fact LOWER RPM  

than the 582....  I am told the 582 has different timing and is more  efficient 

due to rotary valve.

 

Personally, I feel its one fine 2 stroke.

 

Now GSC may have its own limit on prop and I would abide by that, but your  

losing a lot of power...  been there had a GSC ............  the wood  was easy 

to nick....  just a personal choice....

 

you can adjust prop.... been there too.   BUT personally, I would  adjust to 

6,500 to 6,700 WOT 55 mph and cruise will be fine...   if  you add pitch you 

might get off the pipe...been there too very scarey.  

 

Now if you have in flight, different story.....

 

I have about 225 hrs on a 503 and 300 ish on a 582, I have tried all kinds  

of combo, remember this is NOT a 4 stroke, its a tuned 2 stroke ....big  

difference.  they are very peaky

Dont take my word, call Lockwood.... or similar.......  

 

The only warning I can give you is NOT to over pitch a 2 stroke, I went  from 

1,500 feet per min to 500 once when I thought more pitch meant more speed  

and efficiency ....  wrong..

 

Enjoy....

Most of you are talking about rpm at cruise. What should be the max rpm tied

to the ground? Static rpm?

Not at Cruise WOT in Best Climb speed.  

 

I never have tied my plane down and Run it a WOT. Initial  RPM on TO roll is 

a bit over 6,000 and quickly climbs as plane  accelerates.

Greensky Adventures, another guru who's been in the 582 business longer than

the Kitfox has been around, always recommended 5800 WOT static.  It quickly

climbs once the wheels leave the ground.  It keeps the EGTs down and gives

decent cruise at 58-6000 rpm.  Climb rpm is determined by climb speed and

angle.  Worked well for me for 400 hours with GSC prop.  Other props may

need different numbers.

This may explain why my KF2/582 grey/IVO 66" shows such a high cruise speed

at 5800 rpm (88mph). From these posts, it is obvious my prop has too much

pitch. On climb-out, I see 6100 max at 70 mph. I get about 1000fpm solo at

this setting.



I bet if I pitch it to 6500, I'd go vertical.



Nice thing about these props, easy to re-pitch where you want it.
