I had a top c12 and was very fast but i got it second hand and the bearings were leaking so i dont know how old it was or how much fuel was run through it.I like the looks of the Fantom FR.12 the cheapest price motor will be the novarossi @ $100.00 including shipping. 129.00 plus shipping for the Fantom and 119.00 plus s&h for the O.S .12CV-RX
