I installed the Turbulator kit
I made only 1 flight since the installation but I think it is definitely an improvement.
More directional control during start/landing.
And slower stallspeeds.
I heard that Pure flight was busy with an improvement of the weight/balance of the plane. ( increase the weight of the tailwheel).
I asked them why not put a weight in the place of the tailhook for those people who have no intension to do any glidertowing.
They answer that both are possible.
So this summer I fly to Tjechië and install the extra weight in the tailhook area.
I will keep you informed.
