Rotax 503

I’m going to be using an Rotax 503 on my Affordaplane. Do y’all think this will be a good engine for the Affordaplane?

Hi Dave, they only require around 40-45hp where a 503 offeres 50hp depending on which 503 exactly.
I see they have even flown this airframe with a full size VW upfront which is nearly double the weight of the 503. So I would say it seems that a 503 would be a great option.
