Ram Z, what engine have you got. I´m doubting on whether to buy the groovy of the leo and I don’t really know which one to get. I´m planning on using a OS 90 Fx with a perry pump. How much does the groovy 90 weigh? I´ve just finished building the groovy 50 3A and it weighs 2,600 kg a little too much for an .46. Have you made any modifications to the original kit. I personally don’t like the elevator pushrod system.
