I tried it on an Ultra Stik 40 and was somewhat underwhelmed.

The difficulty you will experience setting it up depends entirely upon the capabilities of and your familiarity with the radio used. The concept is simple; flaps are down, ailerons are up.

Perhaps because I do not fly this so-called "3D" is the reason I do not see the uses of crow in a powered model. Not throwing rocks at those who do enjoy 3D; it is simply not my cup of tea.

However, the two extra servos and linkages added substantial weight to the model; it was a borderline pig to fly, even with the power of a 70 Surpass. Perhaps, on a larger model with lighter wing loading, this wouldn't be an issue.

Good luck.
