I spent most of my shop time yesterday taking care of those last minute, but absolutely necessary, details that you must address before that first flight. For example:

Installing the aileron servo.


Here, the servo rails have been epoxied to the underside of the wing.


I secured one aileron in neutral while I adjusted that servo linkage.


Finished. The arms offset to the front will provide aileron differential.

Testing the power system.


With a 4-cell, 4,500 mAh battery reading 16.6 V, the system drew 46 A and consumed 740 W on a 14 x 8 wood prop.

Setting the control throws.


I used the instructions' recommendations for control throws on low rates and boosted the high rates by 30%. Here I was setting the rudder travel. Oh, and I dialed in plenty of exponential.

Adjusting the weight and balance.


When I plopped the Cub on the balancing stand, it was nose heavy, requiring an ounce and a half on the tail. Here is the weight of the model after balancing.

At this weight, I'll have 102 W/lb available at take off.

Let's fly!
