Yeah, no fair flying your model through the rotation!
I use a preset, and have experimented with NOT using one. Not using a preset does require a more upward launch angle, and does risk a tip strike (ask me how I know) but does yield good results. Not any better than with a preset, but in some cases penetrating upwind on the launch is best handled by a more shallow climb angle than your preset may be tuned to.
If windy, and I wanna be upwind, I will throw without a preset. But really, who wants to be upwind anyway
