I just want to throw out an idea. I understand the premise behind creating the Retro IRRA rules set. The Can-Am Plus class is still there, but I do not hear of any activity in that scratchbuilt anglewinder class.
Therefore, would there be any interest in modifying/adding to the IRRA rules by making two changes:
1) Add the other three classes to the Plus and spec the chassis as anglewinder
2) Spec motors at 60K-75K RPM.
The remainder of the rules governing spec, bodies et al could remain the same. Perhaps some fine tuning is needed; I do not know on that. The classes are a little faster, arguably, than the inline Retro specs and the chassis are different, but the Retro essence is there.
Again. This is just a idea and I do not know how much interest, if any, would be in exploring it.
