In the assembly manual for my GP Super Chipmunk ARF, it states that the plane should be set up with different elevator throws. Not just the normal High/Low rates but left and right as well.
On low rates it states Left 1" and Right 5/8" . High Rates 1.25" (left) and 1" ( right).

Can anyone explain why this is so and is it mandatory?
Also what is the impact if one chooses not to set up the model this way?

The rest of the model is pretty standard and it has a DLE 20 in it.

Thanks,

I set the throws equel and started at the low end and then adjusted it a little after I flew it a few times. I put a G-20 in mine. Flaps are very good and will slow the plane down BUT remember to carry a little power until your ready to flare it.

Low rate is for "everyday" flying, High rate is for aerobatic, toss it about the sky type of flying.

No need for dual rates. Hook it up for low rate parameters and then adjust after each flight to fit your flying style.

That's just me, YMMV

The manual that I found for the GP Super Chipmunk with 81 inch wingspan gives the chart below for the control throws. This chart does not tell me to use different throws for each side of the elevator. It does say to use different throws for up vs down on the elevator.
