I'll have to fly it soon, but here you go. A bit late, but better here than never. Not FMS fans, but the notion of lightening and increasing nacelle length to reduce aft weight and required battery size is correct. The forum I posted this info in was clearly the wrong forum. Spec wise it looks good.

Sounds good aeromaniac. Actually more relevant to what you're planning is my Microfan GWS 262. Should have done the same aft lightening that I did on the EDF50 build linked in my last post. Still have it unflown, due to loss of interest. My first flew well until a weak 1.5A linear BEC shutdown. A standard 2A BEC on a 20A ESC would have been fine. It flew well but was heavy for a hand launcher. When I built the Microfan version, it wasn't much lighter and required some lead along with a battery about the same weight 5.5oz that I have my recent build balanced with. I also covered the wing with Microlite, which looks good but adds weight. The nacelle liners used heavy paper, versus the almost transparent vellum I now use that weighs much less than standard paper. The small cable operates a Dubro brake on the removable/steerable nose gear, which works with a 4gm servo and down elevator. The most recent EDF50 build linked in my last post is at least 5oz lighter than the Microfan version below, and probably more like 8oz lighter, if not more.

Got some video of it flying here. Tiny 12mm Feigoa motors/EDF50 fans exceeded my expectations. https://www.rcgroups.com/forums/show...&postcount=413
