As you can get that amount of thrust (and more) out of a 55mm fan now then the set up is fine as you have found.
The whole ducting set up I have in this model is sub optimal (intakes are a bit rough too), 2 kinks around the support boom... I expect to be able to get more thrust, now I have a better understanding of what I'm doing, I have figured out a way to support the wing without such a ridiculously large support boom.

Ok, breaking news... My girl friend has suggested we scale up for the next one... 8ft over the existing 6ft... I'm 100% behind her, but we simply don't have the space to build it that big

Anyone want to loan me a large workshop in West London? Hahahahaha
