Hi guys,

Droped as newbie in pattern forum...Just got Flair's LARK 70 with Magnum 52XLS 2 stroke.
What prop size would you reccomend for this combo ? APC props I can get without problems.

Any help apprecciated.

I would suggest several: 10 X 7, 10 X 8, 11 X 7, 11 X 8, maybe an 11 X 9, 12 X 6. If you are going to fly pattern with it, look for the prop that will give you a nice constant speed plus vertical, without being real zippy (too fast) in straight and level flight. I'm betting an 11 X 7 or a 12 X 6

Regards,
GPB

How big is the Lark-70?

I would recommend an 11x7 for vertical yet fat enough to be crisp-

Cheers-

Lark is 59" span, actually scaled-down Swallow.

Since Magnum 52 is not available, MVVS 49 with tuned pipe will be there.
On recommended prop sizes is also 11x7 so I presume this will make good combo.
