Motor...
A guy in the radio control zone forum was helping break one in. They had to take the head off to get some plug coils out of the sleeve. He said that it's only 4 port. The Ofna/Picco .26 is 7... I'm disappointed. It's probably still OK, but it won't have the 2.7HP at 37000 RPMs of the Ofna motor. It's probably closer to the 2.39 of the Ofna .25. It should still have plenty of torque though with the bigger bore .26.
