The Impact has all the changes plus from what I had discussed with Andreas for a "new" pattern plane. The current Rev-Pro I have electrified is a standard Rev-Pro. I have a white one due in this week that I will probably cut the fillets off of. I may also have a fiberglass canopy made instead of the clear one that comes with the kit. Other than that, this white one will be stock. I have ordered an Impact, but with a due date of Late May, I'm not sure if I'll have time to finish it before the NATS/Team Trials. I don't know anything else about the Impact other than what is posted on the site.
