Star_Scream ,
Your last sentence speaks to one of the reason we started Club 40 in the first place. We wanted to have a fun, simple, slower racing class from which those who caught the fever would want to move up into 424. We wanted to support our 424 brethren by using the same engine as they used. Two reasons: make possible easier transition and cause more demand, so the manufacturer would be happy to continue selling that engine. Yes, we did and have let folks use other .40s. Back then, only 10 years ago, lots of people had .40s and we wanted to sucker, or shall we say entice, them to try racing.
When AMA declared the .46nx equal to the TT Pro, we said, "Yea!" and, in November, voted to include it in our list of approved engines, with no testing on our part.
Our leaders and fast guys all ordered the engine. Lots of bench testing occurred. But the proof is in the pudding and the pudding is when the planes are in the air. Our (Indiana) pudding was in the air on May 14th. It was truly not equal!!!
The committee members decided not to discard the TT 40 but to put the EVO .46 on hold. A case of "Damned if we do and damned if we don't".
Now our best people are testing propellers, trying to get equal pudding.
