[NSRCA-discussion] Partner set-up question

Wed Oct 18 14:18:56 AKDT 2006

George,

I really couldn't tell you- I still need to (finish) building them!!

However, I was hoping that some of you boys in the US might have an answer to that? But I gather that the ratio of Partners to Lazulites is quite high in the US?

I always wondered why there are relatively few Lazulites flying in the US. The Lazulite has a few differences, enough I guess for a selection of pilots. The wing sections are the same, but differ in percentages etc.

George-as far as my expectations are concerned regarding pitch values, I'd expect them both to be about the same. As a rule of thumb, I would have thought the stab which is lower to pitch less-but there are enough differences in stab/wing and fuselage for it to perhaps be the same, i.e.: trimmable with a bit of incidence work.

Incidentally-the marks on either fuselage suggest 0-0 wing stab???? I'd have to draw the fuselages up to see rigging angles.

Tom

Hey Tom,
What are the differences in the mix values between these two models? Particularly pitch values. Your opinion please.
Geo.

Hello Claude and all,

These are the measurements I came up with. Please-if anyone has other data it would be interesting to compare. First up nothing earth shattering as far as the numbers are concerned. Quite standard actually.

Partner

With reference to the canopy floor.

Datum line/spinner center    56 mm below canopy line
wing center                        92 mm below canopy line( or 36 mm below datum line)
stab center                        63 mm below canopy line( or 7 mm below datum line)

Lazulite

With reference to the canopy floor.

Datum line/spinner center    56 mm below canopy line
wing center                        90 mm below canopy line( or 34 mm below datum line)
stab center                       57 mm below canopy line( or 1 mm below datum line)

I presume that with the stab center on the Lazulite, I may have made an error in measurement and that the stab is actually located ON the datum line( it was getting late!)

The models are actually very similar, with a bit of coaxing the Lazulite Canopy will fit on a Partner and vice versa.

I have not compared 1/4 chord to 1/4 chord moments-but if these are wanted I'll measure that up as well.

The Lazulite was disgustingly close ( by millimeters) to my own Merlin design.I'm still kicking myself for the cash that was 'burnt'.

Hope it is of help.

Tom

Tom,

No one else has responded.  I would really appreciate if you could give me the information. I can deal with metrics if that's what you use.

Thanks, Claude

Claude,

Have you had any answers yet?

If not-I'll measure up my unbuilt one and see what the numbers are. I hope they will make sense with the results from others?

Can some one tell me the distance below the engine thrust line to the centerline of the wing on the Partner? And I would also like to know the distance above the wing centerline to the center of the horizontal stab. Thanks, Claude.
