Enerjet by Aerotech Strong Arm Build, Part 4, Strakes

On the left is the front of the strake, on the right is the rear.

The final tip cuts are marked with pencil.

Cut them a little wide outside the pencil lines. Then sand to shape with a block.

TIP: It's easier to visualize the shape by turning over the strake and checking the bottom.

I drew a centerline to better see the wedge shape.

Engine Removal Tip?

Mike Meyer posted on the Facebook Estes Model Rockets page:

"I was finishing up the Super Orbital Transport today.

I got the bright idea to stuff a D engine in. It went in flush with the tube and wouldn’t slide back out. Tried a few knives and then knew what I had to do. I used a cork screw to yank it out. But then I noticed the retainer clip slid out a 1/4 inch. And I was able to clear everything. Still not sure how the clip slides but here’s a few pics to illustrate my wine bottle cork removal process."

It was worth a try, but maybe not the best way to remove an engine. The corkscrew also pulled and tore the engine hook down the engine mount tube 1/4".
