Here is another goofy law of aerodynamics to ponder---
If wing loading is low enough - the deflection of the elevator will never be excessive---
before you yell "impossible!"
fly a really GOOD 3D Shock Flyer type model - with any good one -- you can do a full bore vertical dive -chop power -yank elevator to 50 degrees (easy to do) and the model will simply snap to horizontal flight and settle .
I grew up on models which sometimes rolled upon application of elevator - including control line stuff which was really wierd.
The more I play with these really low inertia electrics - the more I see where flight problems really originate.
- we are all used to designs which are fairly heavy and/or low on power
.This is a logical intrepretation of the flight envelope of the majority of full scale designs from the past.
No one is to blame -
It is simply a fact that from the first flight - any meaningful advance was based on better power to weight and lower weight to size.
