Gee, Dave- when we were corresponding last year about an Arcus model
WingRigger, you were adamant that the linear actuator was "too complex
and unnecessary."...

Unfortunately, the proportionality of a gas spring that fits inside the
IMI structure is too high - otherwise gas spring would be preferable.
If you can fit a gas spring with more constant force, that would be best.

I find that a combination of the spring and actuator is preferable.

Using both is just unnecessary complexity, cost, and weight.


Now, how about a thank-you for repeatedly providing you with engineering
data and measurements, instead of snide comments? Really now.

Thanks,
