John,

Agreed, they need to be dependable, but if you already own them & they run well, you should have no trouble. Make sure you've got an airtight fuel system as the lines are quite long from the center section tanks to the engine nacelle's. Not sure how good the fuel draw is on those motors. I've used some other HP 2strokes years back and always found them to be decent quality.

BTW, go for the scale rudder hinge. Lot's of work but it REALLY looks good!
