I'm right handed so I hold the transmiter in my left hand advance throtle to full. Grasp fusalage
under wing near center of gravity. Toss the plane briskly straight ahead like launching a toy glider or like trowing a spear.

If the elevator and rudder are at netrual you should have plenty of time to get to the sticks.
For insurance I sometimes add a tiny bit of up elevator with the trims to insure a shallow climb.
By tiny I mean when you look at the elevator edge on you can just barley see that is up from netrual. Maybe 1/32-1/16 of an inch up.

It's scary if you've never done it before. If you can launch over tall grass. If things go wrong the grass can save you're plane from serious damage.

Good luck,
Oscar
