Warning [X(] !!!!!

Noobie alert

Prepare to roll your eyeballs outta your head .

I'm building a plane restraint for use at the field/testing engines in the plane/flight-line etc and I have an uber-simple question.

How high should the support be (from ground level) for the uprights ? I have a tail-dragger trainer but I want this thing tall enough so that as I advance it'll be high enough for tricycle - gear equipped planes. But no Giant scale stuff as I don't ever see going there.

Generally speaking, how high does the top of the elevator sit above ground level at it's "max" for your most typical planes ?

Muchos thankos !!!!
