I've got a manual start MW54 Mk1 (12#) in my "classic" BVM Fury. No bypass and a carbon-fiber 65oz. fuel tank which was designed by someone before BV did a conversion kit (came out of Gordon's early F86 with the FD3/67). It flies great. It's not overpowered, nor underpowered and weighs 14.5 lbs. dry. I'm looking forward to flying it again after either repairing my wing, or by some miracle, finding another "old style" wing kit or built wing for sale. Its a great flying plane with this power setup, and a couple more pounds of thrust would be even better still. Good luck with yours!
