Finally, test on RWY at low speed. With assistance from the good neighbor, I made some 90, 180 and 360 turns on apron. Brake and steering work good. Continue on RWY at very low speed, check hard braking and steering. No problems, but I have to increase tire pressure at nosewheel. After 5 rounds, will be about10 km, I found cooling temp was near 100 C. So to be safe I returned to hangar. I have some ideas how to increase airflow to cooler.
