Hello All

I am a very raw begineer at MOI, I have had some success and got things right through to being machined.

However I am trying to model a simple tailplane for a model aircraft, my problem comes at the wing tip, I have scaled a common section with seemingly plenty of stations near the tip, but I still get a nasty looking hard edge in the surface. I am lofting down through the sections.

I have attached a red lined image showing where the problem is.

Any pointers to getting a nice surface would be appriciated.

Regards

Barrie
