I have a couple questions about an extra 300XL. I am thinking of buying one that has been modified with giant control surfaces and a lightweight design for 3d flying. Do extras in general snap roll when you pull up hard like a cap? does it nose tuck when full rudder is applied? those are the two symptoms i collide with and am very dissappointed with in my cap. Are there any other bad habbits the extra inherently has?

Spaceclam,

I dont have any first hand knowlege about the Extras, but what I've heard from a few of the flyers at the club is that all aircraft will snap if too much evelvator is defelcted at too high a speed. The cap is Notorious.... I've had 3 of them.

Either mix lots of EXPONENTIAL into the elevator or fly with dual rates on when flying normally and switch them off when you wanna do 3D stuff!!

i can't do 3d, it is way to heavy. 28 oz/sq ft. i am actually kinda dissappointed. the extra i am looking at is 20 oz/sq ft.

Virtually any airplane will snap roll upon application of "up" elevator, if the elevator travel is in excess of what is required to force the wing in a stalling angle of attack. For normal, non-3d aerobatic flying, I try to adjust elevator travel until it is just sufficient to stall the wing. I take the model up high, apply full power, and full up elevator. If the model fails to complete a single loop before yawing and rolling away off track, the elevator travel is excessive. If it continues looping steadily, staying pretty much on track, the elevator travel is insufficient. I find that best overall results are obtained by fiddling with elevator travel until the model flies roughly one full loop before going crazy. This means that you can apply full "up" elevator close to the ground without having the model snap over on its back and bore into the ground. I repeat the process with the model inverted, applying full "down", to set the "down" elevator travel.

I have seen too many nice models crashed by application of too much elevator when recovering from a dive at low altitude.

So-called 3d flying normally requires much more elevator travel than normal aerobatics, so great care has to be exercised to avoid inadvertently applying too much elevator deflection. The best way to do this is to fling the model around at a safe altitude to determine what you can get away with, and how quickly you can recover.

ok, i see that. But my real concern is that the cap can't make any tight turns, or pull up quickly or anything because it snaps. will an extra be able to make tight turns and pull up quickly?
