Estes Scissor Wing Transport Build, Part 17, C/G Balance

The kit supplied clay pat weighed .25 oz.

I ended up using .17 oz. to get the model to balance 8 1/4" from the elevator hinge as shown in the instructions.

To balance the model I made a "V" with my thumb and forefinger at the 8 1/4" point. I couldn't balance the model on a straightedge.
I would think the clay weight would go in the hollow nose cone but my weight went inside the rear tube.
The rubber band has been fitted over the two posts on the pivot.

With the wing tip sticker in place, the wing tip fit is too tight between the posts on the wing holder. I'll have to lightly sand top to open up the inside span of the plastic post extensions.

Estes Curvilinear #3231, Build, Parts 9, Tape Reveal and C/G

The tape was pulled and the color separation was pretty good.

The ring was slid into place. The color separation is sharp between the ring and fin slots.

Here's why the engine mounts weren't glued in earlier. I have to find the center of gravity (C/G) of the model with 13mm engine mount in place.
With the 5/60 mount slipped in with an A10-3t engine, the balance point was 3 1/2" from the rear edge of the main tube.

The 18mm engine mount was inserted with a B6-4 engine in place. I doubt I would ever use a C6 engine in this rocket. Bits of cay weight were added and stuck on the outside of the nose cone until it balanced at 3 1/2" from the rear.
The total clay weight added to compensate for the 18mm engine mount was .16 oz.

Estes Skydart II #3229 Build, Step 23, C/G Balance Point

On the back of the smaller Parts List is the glide trimming directions. The balance point (without the pop pod inside) is 5" from the back of the body tube.

This was a hard picture to take!
I pencil marked the body with a pencil at the 5" point. Here the model was balanced on a straightedge.





The supplied clay weight starts at almost .25 ounce.
Bits of clay were added to the inside of the nose cone until it balanced at the 5" mark.
In the end .08 oz. of clay was pressed into the nose cone. Your model balance weight may vary -
