Again we have a case of two pilots, two ways of doin it!!! Mostly I also adj. at ther front!! However I needed to tighten my belt last night and had the issue Sur. decribed needing to cut more slot in the boom. Not wanting to take it apart, and knowing I'd be taking it apart soon I opted to adj. from the tail box and it works just fine.. So I think either way is ok!! BUT if time is not a factor and you don't need to slot the boom doin it from the front is the best way!!!
