Durafly Autogyro G2 V2 Rd.4 Success, Hi Viz & Crash Analysis

Another 'day out' with this unique flyer!!! This time I have some flying success, but also a big failure. Unlike previous flights/crashes where the aircraft seemed to just fly beyond its limits, regardless of my stick inputs, this time however it was easy to analyse what went wrong - pure pilot error. On approach to landing i flew too close to myself and overcompensated with elevator causing the craft to lose momentum and stall, by the time it had flown past me it was too late to correct as it had commenced a severe stall turn, leading to the inevitable crash. There are more videos to follow of subsequent crashes which i cannot explain. The next day out resulted in a straight nose dive into the ground, it occurred about one football field length from me so the best i can guess is perhaps a radio error, so i swapped out the receiver and did some other minor adjustments. The next next day out was another short flight in near perfect flying conditions, she adopted a right bank angle that i could not apply enough counter aileron movement, resulting in another crash (on board videos to follow - time permitting) . At this stage I am despairing somewhat , due to the endless repairs and blade replacements etc. All advice would be appreciated . I am inclined to think that c. of g. is probably an issue with this as forums suggest that the craft maybe a bit tail heavy and perhaps pilots should be looking at a greater tilting angle, definitely in excess of the recommended 3-5 degrees below horizon.
