Quest/Enerjet Quad Runner Build #Q5016, Part 6, Fin Spacing Guide & Fin Gluing

GOTHCHA: Well, the Fin Marking Guide cut from the instruction sheet didn't fit, the ends didn't match up.

I went to payloadbay.com. then tools to find the fin marking guide link.

I first typed in the diameter of 1.97" but it printed a bit small.

1.98" diameter was a better size.

The picture on the right shows the correct fit.

Two 3/16" diameter launch lugs are supplied.

One is glued even with the low end of the body tube.

The upper lug is glued 8" from the top of the lower lug.

 

My first glue line is evened out by making a "V" with my thumb and index finger. Draw the "V" down the glue line making a even bead. 

The fins and body tube were filled with CWF and sanded. Filler/Primer was sprayed and sanded.

I set a fin next to the root edge glue line and mark below the top tip of the leading edge.

The tube is scraped, down to the bare tube for a stronger glue joint. 

Scrape almost to the top of the root edge length.

After scraping off the filler/primer, re-draw the fin lines with pencil and a aluminum angle.
