I would use flaps.
I have hundreds of flights on Savex L39 and you should remember, it has a fairly high wing loading.

As EDF you do not have the advantage of landing ‘lighter’ than take off.
Use around 5 deg of flap for take off and around 45 deg for landing.
Combine the landing flap with around 1 to 2 mm of down trim.
When setting up the flaps, ensure each side move exactly the same.

As you decelerate to landing, on the downwind leg, deploy takeoff flap and continue to decelerate.
Make you cross wind turn and deploy main landing flap.
By doing this on the crosswind leg you can ‘read’ the rate of descent and speed.
Be prepared to add power, the landing flap ‘really’ slows her down.
Set your rate of descent with power, not elevator.

Make your final turn and adjust power to increase or decrease descent as required.

As has been said, check flaps at altitude first to ensure that they are balanced and to know what to expect!
