Jim, TCKC TaG program hasnt changed, there isnt one. Until recently this area has been prodomently 4cycle but that is slowly changing. This is also the reason getting an x30 would be ill advised from a club standpoinT but it looks to be the better engine. out of curiosity, if we had a TAG class would you come back on occasion? Maybe i can sell it to the board.
Thought rotax but id prefer to do my own maintenance and tuning a rotax is not fun from what i know.
see if i can talk to jerry about his x30 and maybe look into the x125t.
As for price, seen both listed as used for about 2+/1 x30 / prd.
