Hi All: My 14 yr old daughter and I have been chipping away at a K2 (S/N <3000) for about 6 months. We're 2/3 of the way through the RF board, having completed the control and front panel boards. Would you suggest we complete the kit and then backfill with all the Rev B updates? Or would there be something to be gained by trying to do those updates as we go along? Tnx de Brian W3BW
