I flew with Gennady at Skytrace. I would highly recommend him for instruction. He not only knows the 52 inside out but can offer both ab initio training and advanced aerobatic training to a very high standard. You will be a much better pilot as a result of flying with him.
Personally I would not recommend that a low time PPL jumps straight into a 52 without appropriate training. Its cheap insurance really!
