As mentioned before power or speed is your friend.
If you can master to fly that thing, you will probably be pro.lol
Good lord..... a V tail without airlerons.

Just give it full power to pull it thur the turns.
Back out the power on straight ways to conserve the juice.

Read up on lift theary.
wind over and under the wing via by the prop (power)
Or speed. Just extend your arm out and swing it back and forth.
Feel the wind ?

A glider fly in this way also aside from thermal.
Gravity pulls the glider towards the the earth.
Speed it gain thereby more wind is generated.

When your plane stalled and started towards the ground.
Instead of pulling on the elevator. neaturalzize the controls.
The plane will head toward the ground faster to gain speed so the wing
can start flying again. I guess give yourself plenty of altitude.lol

The control surfaces only change the pitch of the plane or AOA of the wing
it will not lift the wing or the plane.
There's a maxium pitch or AOA until lift is lost.
Pulling up on the elevator will only cuase the wing to stall or stop flying
if there's not enough turst or power.

The controls will also be less effective with less wind.

To make a tight turn around ?
Do a stall trun as a turn around
Kind of like a skateboarder riding a half pipe pattern.

have fun, don't give up
