I was a bit concerned about nose stability (no maple mounts to stabilize it). I build a couple of different setups; these fillets, some cheek cowls and a sort of weird, molded wrap around, but didn't really like any of them. This is the only one I was really much considering at this point. It gives a very cool plan view, but overall, I didn't like it much. Now that I'm down to it, I was reconsidering. I'll look at it again today. they would make little difference in final weight but may add something to nose stability. Same reason I have those long fairings on the flaps. The nose looks a bit blockier than I had planned. If I don't put the fillet on, I may rework the cowl to give it a somewhat less blocky look.
