Posted: Mon Sep 12, 2011 6:43 pm Post subject: GSC Prop

We have a 582 Pulsar ready to fly but the prop is only allowing 5600 RPM  static, which is too low for flight. If take off were attempted the prop would  load up and the RPM would drop. This could be a break in issue on the engine or  his prop may have too much pitch.  

  

 Does anyone have a prop for a 582 Pulsar, perhaps a GSC ground adjustable,  that he can borrow or purchase? He is grounded until he gets a replacement.  

  

  

  

 Thanks,

 Greg Smith

Greg:

	I have an original fixed pitch Perry prop that would not allow me  

sufficient Rpm when I had the the 2:1 gear reduction and was breaking in  

the engine.

	If he has the 2.24:1 gear ratio in his motor reduction unit, he is more  

than welcome to try it.

A few points on the 582 and Peery prop.

 

1) do NOT believe the ratio that is stamped on the 582 gearbox. Do a physical check so to make sure you 

      DO have a 2:1  ratio   gearbox.  As an ex Rotax service agent, I meet a few that were incorrectly stamped.

 

2) not all Peery props had the exact pitch (albeit they has small variation).

 

3) you must have at least 5800 RPM on  static run-up, but best not more than 6000 RPM static.

 

4) here in the UK, if we could not achieve 5800 RPM static with the supplied Peery prop, then we ran in our 582 

      (and  flew for up to 10 hours) with a "clipped" Perry prop.

 

5)  In my Pulsar 582, I fitted the supplied Peery prop, but had to "clip" that prop.  I cut off about 1/4" at the

      prop tips so to achieve the static 5800 RPM. I ran for a further 300 hours with this prop. with no adverse 

       problems.

 

6)  I test flew Pulsar 582,s for our UK builders, and never attempted a flight with-out a minimum 5800 RPM

     static run-up. Anything less, then the 582 can "baulk" down during take-off.

 

My pennies worth!!

Alan, I have had the same experiences here in the States on test flights so  I know the feeling. Most of the time, if the prop is going to load up, it does  it on take off roll but I did have it happen once at about 200 feet on climb  out. In that case, 1/2 degree was all it took to correct the problem. But your  are right, the original Perry props were sometimes not correct or mismatched to  the gear box. 

 In this case, he is using a Culver prop, but again, it may not be right. I  have always liked the GSC adjustable for the 582. It provided a way to adjust  for winter and summer to get peak performance.
