Get on G and practice with a Viper a bit - it will help. The Freedom will do what you tell it. Visualize yourself in the pilot's seat. Full throttle on takeoff, the rest of the flight around half. Fly a racetrack pattern, and don't let it get out where you have trouble seeing it. First flight, make right turns only. Right aileron to bank, up elevator to bring it around, left aileron to level. Fly it right down the runway on the upwind pass, then tiurn right and parallel the runway on downwind. Once you have it trimmed to fly hands-off, take it up a couple hundred feet and pull back to idle on an upwind leg to check stall speed and characteristics. (BTW, did you check lateral balance?) When you were running the engine, did you happen to get a timed run at full throttle?

Keep your first few flights short. Mental fatigue sets in quickly, and you'll start making mistakes when it does. If you have enough room, take off by standing directly behind the plane, ease it up a foot or two, cut the power and land WITHOUT turning. Stop and examine what you observed - did the plane track straight on the ground, did it stay straight in the air? Taxi back and adjust the trims, repeat until the plane rolls straight and climbs out without a fight.

Landings are easiest if you are positioned behind and to the side of the plane. I have students fly the racetrack pattern until they can do so at a consistent altitude at cruising speed, then I reduce the throttle a little each circuit until they are starting to make a gentle descent. The airplane will handle differently at different speeds - just like a full scale one. When you can fly slowly - gentle turns and hold heading - you are ready to land. As you turn onto final, reduce throttle to idle and hold a touch of up elevator in. Use elevator to control pitch, throttle for rate of descent. Mains down first, then the nosewheel.
