Estes Gauchito Build #1279 OOP, Part 3, Engine Mount Prep




On the left is the motor mount tube supplied in the kit. The seam gaps were wide and the tube felt weak.
I cut a new BT-5 tube to substitute.






The Mylar engine hook hold down ring had some cut burrs on both sides. With a new knife blade I was able to shave it smooth.






The fins were laser cut but the centering rings were old-school die cut.
The fit on the BT-5 motor mount tube was very tight. A few passes with some 220 grit sand paper and I had a good friction fit.


I've learned from past experience - 
Be sure the engine hook is straight before gluing on the entering rings.
The picture on the left shows a crooked engine hook.

  1. Excellent advice. When an engine hook is glued in crooked it also shortens the overall length of the hook, which may hinder the engine from fitting underneath it.
