RE: Mini F-16 vintage project consideration
Looks like my Balsa should arrive tomorrow, not much I can do untill then. I built an adapter or mandrel to wrap the 1/64 ply around but it's not perfect. I think I am just going to use the rings I had cut and some clamps with some hardwood. Lets see how it looks once I get some material in my hands.
Also I purchsed off of Ebay a CD of Ducted fan design articles including the Kress design documents. Interesting stuff. According to cres the annual area of the fan sweep should be equal to the OD of the tail pipe for a zero restritcting flow. The way I designed my fan I'll need to choke off the taip pipe a bit. Plus it looks really important that I get the inlet fairing right. I'm not sure how I am going to do that. I was thinking a large foam block but maybe Balsa would be easier to deal with. I'm not sure how I am going to do that yet.
