mlyle No, this was on the Sparky, RE1 has no support due to that missing module. I'm using the latest BLHELISuite, BLHeliSuite16614902, but the previous one, BLHeliSuite16614901 also has the same problem. Appreciate your help, though.
EDIT: Just tried with BLHeliSuite16514802, same problem. After those failures on MSP_3D, it's all OKs all the way down. Then the app gives that "Abstract Error" and eventually crashes. Considering BLHELIConfigurator works fine, it's most probably a BLHELISuite screw up. At the very least, the app shouldn't crash.
