Semroc Cherokee D Build Part 3, 24mm Engine Mount

Look at the left side of the picture. You can see the engine hook compressing the BT-50 motor mount tube.

The instructions don't mention notching the centering ring for a better fit of the engine hook.

TIP:

Anytime a part deforms a tube like this, you should notch the ring. It won't take much to relieve the pressure.

The inset picture on the right shows notched ring and the rounder tube.

Sometimes engine fit can be tight. Imagine how much tighter the engine would be if the motor mount tube was compressed and out of round.

Here's the finished 24mm engine mount.

TIP:
Use black electrical tape to hold down the engine hook.
I recently opened up an older model where a masking tape wrap was in  place. The tape was dried out and flaked off the engine tube!

TIP:
Wait to do your tape wrap until after the centering rings are in place.
With the rings glued in place you can set the tape closer to the actual center.

BUILD TIME: 24mm Engine Mount = 20 minutes
TOTAL BUILD TIME so far = 50 minutes
