Partner and Lazulite elevators

[Dean Pappas]

Hi John,
No correction here, though I would like to add some. You're quite right about the snaps, but they aren't the thing that has driven elevator size for me, over the years. Spin entries have. I still haven't found the stab/elevator airfoil that will give reasonable sensitivity at high speed, and still enable me to reliably drive the plane into a deep stall, without just an airplane-length of climb at the very end.
I've gone back and forth with Nat on this one, several times over the years, and still no great breakthrough. Probably the best I had was the old MAYA II, and it had a thick stab and very large elevator.
 
Still looking for a magic bullet.

I am curious why you would want to increase the elevator size. 
I have observed several instances where decreasing the stab size has resulted in a perceived improvement in snapping. 
I think that increasing the elevator size amplifies the effects of control system shortcomings.
It also decreases the drag vector magnitude that occurs on operation of the surface. I suspect that to be small enough to be insignificant.
 
I am ready to be corrected...

Hi again all, 

Owners of the Pl Partner and Lazulites, I would like your thoughts. 

Before I finish the stabs and elevators, I am somewhat concerned at the very small elevators found on these models. I've seen one Partner fly and the owner suggested to DEFINATELY enlarge the elevators. I tend to agree...but who am I to argue with Quique and the Matt's design philosophy.

If the consensus is to make them bigger, then I will, as sofar I'm not comfortable with their current size. 

Thanks for any ideas. 

best regards 

Tom 

PS: If any of you have been cruising on any Aussie sites recently....the guy who just had his behind kicked at our State champs and W/C team trials...was NOT me ( he just happens to look like me, have the same name and job, seems to be married to the same woman....OK..... OK it was me, I admit it !)

Shall we just say I had a shocker of a weekend ?
