Oooohhh......your pix of vertical fin in post #417
Cant tell much from the angle of your photo.....don't make that ECM fairing too fat.....Ken Williams made that mistake with his old K&A F-100.......the fairing wasn't parallel taper and square.
Maybe too late to alter the plug?

Your effort is looking great.

Hi Mike,

Yep, already molded it so too late. I am sure its too fat. Mine has a straight top and bottom edge and trailing edge is not scale either. If it looks reasonable, thats good enough for me.

really you think so? I think its the low resolution pic. That was 1 minute after removing the plug they have not been polished up yet. I am done trying to make things perfect so the plug was only sanded 2 400 grit. I even dinged it in a couple places in actually filled it with clay and smoothed it over before molding lol. if its going to be painted outside the mold I figured what difference does it make how perfect it is.

I glassed the mold for the ducting the other day and then decided to test fit and realize that the nose gear would not fit so had to modify it and re glass the bottom section

well I am a little bumed. I tried to order E flite landing gear from Billy at USA RC jets and found out the guy he get the upgraded trunnions from is no longer making them so I had to go with air retracts I had from a composite ARF rookie. I love the e flite retracts I have in my xxx so I was hoping to use them in this as well.

moving on. I got the nose gear formers installed. What a pain in the butt that was to get the weird angle that the f-100 has. this is the part I love and hate about scratch building. its fun to try to figure out and solve problems but can also be frustrating. It was very difficult to get the right angle and also make sure that the landing gear and wheel does not hit the ducting.

Gotta live the look of the Hun!
