RE: need a easy flyer for a OS46la
I flew my Four Star 40 for two seasons with a .46LA. It was a good setup for normal sport flying, it just lacked vertical climbing ability.
That engine is now flying my new Dazzler. It's a smaller plane, so the power is a better match. I don't think the Dazzler qualifies as a lazy Sunday flyer, though.
The new GP Escapade ARF would be a good fit as well.
Good luck
