Does anyone have a line on how to find the Procise automatic centre punch? They don't have them at my Home Depot and I can't find them online either. Such a great solution for balancing the motor housings on the Phantom. Maybe there's a practical alternative? On a related note, the balancing bar I got from Atlanta Hobby will not thread the extra props I just bought, even though the props fit perfectly on the Phantom motor housings. Go figure.... (A.H. is out of stock on them but agreed to send me another one when they're in....)
