A rating system would be nice for these motors.
For example, I used to run an OS 21vg(not mentioned). For the 120-140 you pay for them, you can certianly beat the snot out of them for the price. With a high nitro fuel they run hot.
There is a local guy that runs what I believe is that Novarossi limited. An awesome motor for the price. His buggy hauls!
One of the guys had a Picco. It was dead in under a gallon. The OEM would not support it. The LHS could do nothing because the motor was discontinued. That was the first and last one raced at the track.
Over all I like the list!
*** side note ***
Anyone try out that Odonnell? I would like to stick that into my Revo or maybe my SC8.
