Miguel,

The marks to drill the holes for the temporary bolts that hold the nose section to the fuse are visible. Be as careful as you can and drill those as accurately as possible and then test fit the nose to the main body. You are looking for 3 things in my opinion....

1. the fit of the top of the nose section to the main body

2. the fit of the bottom of the nose section to the main body

3. and that the distance from the nose section to the edge of the intake is the same on each side of the nose.

Adjust the bolt holes slightly to achieve the desired fit. Philips method of CAing balsa sticks over masking tape at the joints works like a champ.

Take it in steps though

First glue the nose to the main body by only glueing the nose sides to the intake sides (still make sure the top of the nose and bottom of the nose align with the main body)

Once set, it is easier to come back and add cloth/epoxy to the upper and lower joints and add any additional reinforcement you want.

Sorry but I can't help you with the intakes as I am not going to do that mod.

Hope this helps
