Flying Tips Elevator
Exponential
To
execute smooth slow rolls, point rolls and inverted flight it is very helpful
to have the model feel the same when it is inverted as it does when flying
right side up. Most good
flying jets have built-in positive stability about the lateral axis with
emphasis on their "up right" condition. To get the right elevator feel you can increase the ATV travel of
the down elevator and, more importantly, apply some "negative exponential" to
this side of the channel. As an
example, my 60" F-86 utilizes 35% positive expo on up elevator and 15% negative
expo on down elevator. ATV's are 110% up and 115% down. Slight variances in component installation,
and C.G. will affect the final numbers that make your model "feel" right - you
just have to make adjustments between flights until you get it right for
you.
